Subject: [PATCH] powerpc: Remove sections use from ppc64 and drivers

Here is a new patch that removes all notion of the pmac, prep,
chrp and openfirmware initialization sections, and then unifies
the sections.h files without those __pmac, etc, sections identifiers
cluttering things up.

Subject: [PATCH] ppc64: Updated Olof iommu updates 1/3

Split out the implementation-specific parts of include/asm-ppc64/iommu.h
to separate include files (tce.h and dart.h respectively).

The generic iommu code really doesn't care about the underlying
implementation, and the TCE and DART stuff is completely different.

Subject: [PATCH] ppc64: Updated Olof iommu updates 2/3

There are potential cases in the future where the IOMMU might be
mapping smaller pages than the regular MMU is using. Keep the
allocator working on MMU pagesizes, but the low-level mapping
functions need to map more than one TCE entry per page to deal with
this.

Subject: [PATCH] ppc64: Updated Olof misc updates 3/3

Replace some of the hard-coded constants with PAGE_SIZE/SHIFT/ORDER where
appropriate.

Likewise, in a couple of places it doesn't make sense to base some
allocations on page size when all that's required is a constant 4K,
etc.

Subject: [PATCH] ppc64: Store virtual address in TLB flush batches

This patch slightly change the TLB flush batch mecanism so that we
store the full vaddr (including vsid) when adding an entry to the
batch so that the flush part doesn't have to get to the context.

This cleans it a bit, and paves the way to future updates like
dynamic vsids.

Subject: [PATCH] powerpc: unified signature of timer_interrupt() between
 ppc32/ppc64

On ppc64 timer_interrupt() returned a value that was never used.  Changed
the ppc64 version of timer_interrupt() to no longer return a value so
that the signatures between ppc32 & ppc64 match.  This will simplify
future merging of arch/powerpc.

Subject: ppc46 iSeries: Make some generic irq code compile for iSeries

In order to call finish_device_tree() on iSeries we need to define
virt_irq_create_mapping(). We also need to set ppc64_interrupt_controller to
something other than zero. If we want to do interrupt setup via the device
tree on iSeries this code will need some serious work, but it's harmless to
have it there as long as the nodes in the iSeries device tree don't cause
it to be invoked.

Subject: ppc64 iSeries: Update create_pte_mapping to replace
 iSeries_bolt_kernel()

early_setup() calls htab_initialize() which is similar, but not identical
to iSeries_bolt_kernel().

On iSeries the Hypervisor has already inserted some ptes for us, and we
simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert()
implements that logic.

For the case of a non-existing pte we just call iSeries_hpte_insert(). This
appears to work, although it's not entirely equivalent to the old code in
iSeries_make_pte() which panicked if we got a secondary slot. Not sure if
that's important.

Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(),
which is called from htab_initialize() for each lmb region.

We don't need to call stab_initialize() for the boot cpu on iSeries, so
we hack around it so that early_setup() can be called on iSeries.

Subject: ppc64 iSeries: Call early_setup() on iSeries

Misc steps to incorporate the flat device tree on iSeries.

- define iseries_probe()
- call build_iSeries_Memory_Map() earlier
- return __pa() of the flat device tree from iSeries_early_setup()
- actually call early_setup() for iSeries
- add iseries_md to machdep_calls
- build prom.o for iSeries
- enable /proc/device-tree for iSeries

Subject: ppc64 iSeries: Move setup of systemcfg->platform into iSeries device
 tree

Add /chosen/linux,platform to the device tree so we can remove iSeries
specific code in setup_system() to set systemcfg->platform.

Subject: ppc64 iSeries: Define /cpus in iSeries device tree

Add the /cpus node and nodes for each cpu, as well as cache size properties,
reg propery, "linux,boot-cpu", and timebase/clock frequency.

With those properties in place we can remove:

- setup_iSeries_cache_sizes()
- code in iSeries_setup_arch() to calculate timebase etc.
- iSeries_calibrate_decr()
- smp_iSeries_numProcs() and simplify smp_iSeries_probe()

From c8b84976f86adcd10c221d398e1d0be2b778f3c8 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Tue, 27 Sep 2005 18:44:42 +1000
Subject: powerpc: move iSeries_setup.[ch] and mf.c into platforms/iseries

iSeries_setup.c becomes setup.c
iSeries_setup.h becomes setup.h
mf.c retains its name

Also moved iSeries_[gs]et_rtc_time and iSeries_get_boot_time into
mf.c since they are just small wrappers around mf_ functions.

Subject: powerpc: move hvCall.s to powerpc/platforms/iseries

Rename it to hvcall.S and (so I can do that) rename hvcall.c
to hvlog.c - a more appropriate name.

Do some white space cleanups.

Subject: powerpc: Move iSeries_pci.c to powerpc/platform/iseries

and rename it to pci.c.  This also required moving
arch/ppc64/kernel/pci.h into include/asm-powerpc (called
ppc-pci.h.

Subject: [PATCH] powerpc: merged asm/cputable.h

Merged cputable.h between ppc32 and ppc64.  In doing this removed support
for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
dont compile correctly.  C code should use cpu_has_feature().  This is
based on Arnd Bergmann's initial patch.

Subject: powerpc: merge idle_power4.S and trapc.s

Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype

Subject: powerpc: Use SPRN_xxx rather than xxx for SPR numbers

This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to
special purpose registers to SPRN_HID0, SPRN_SPRG3, etc.  Using the
SPRN_ symbols clutters the namespace less, and the forthcoming merge
of asm/processor.h and asm/reg.h is going to remove the non-SPRN_
versions.

Subject: ppc64: Use SPRN_ prefix for special purpose register names

Now that we are using the merged reg.h we have to use the SPRN_xxx
names rather than the xxx names.

Since lparmap.s gets included in arch/powerpc/kernel/head_64.S,
this avoids depending on a file in another directory.

Subject: powerpc: Get 64-bit configs to compile with ARCH=powerpc

This is a bunch of mostly small fixes that are needed to get
ARCH=powerpc to compile for 64-bit.  This adds setup_64.c from
arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c.

Subject: ppc64: compile fix - define execve in misc.S

inline in the merged include/asm-powerpc/unistd.h, so we need a
definition here.

Subject: powerpc: move iSeries/iSeries_pci.h to platforms/iseries

The only real user of this file outside platforms/iseries was
drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR()
so we move that to abs_addr.h (and lowercase it).

Subject: powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpc

This makes ppc use the syscalls.c from arch/powerpc/kernel, exports
copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc),
and consolidates the sys_fadvise64_64 implementations for 32-bit.

Subject: powerpc: change sys32_ to compat_sys_

This allows us to get rid of one type of entry in systbl.S.

In passing we remove the duplicate compat_sys_getdents and
compat_sys_utimes for which there are generic versions.

From 143a1dec7e04e0a9712ff93e779aabfb21dfd97c Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Wed, 19 Oct 2005 23:11:21 +1000
Subject: powerpc: Merge machdep.h

A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

Subject: ppc64: Minor compilation fixes

This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of
sys32_ to compat_sys_ in the ppc64 syscall table, and removes a
reference to a non-existent arch/powerpc/xmon/Makefile.

From: Paul Mackerras <paulus@samba.org>

Subject: powerpc: Merge time.c and asm/time.h.

We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c.  This also makes an
asm-powerpc/rtc.h.

From: David Gibson <david@gibson.dropbear.id.au>
Date: Wed, 19 Oct 2005 14:53:32 +1000
Subject: [PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]

This patches the ppc32 and ppc64 versions of the headers and .c files
with helper functions for manipulating the performance counting
hardware.  As a side effect, it removes use of the term "perfmon" from
ppc32, thus avoiding confusion with the unrelated performance counter
interface from HP Labs also called "perfmon".

Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac
with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

Subject: powerpc: Move some calculations from xxx_calibrate_decr to time_init

Previously the individual xxx_calibrate_decr functions would each
print the timebase and cpu frequency and calculate several values
such as tb_to_us and tb_to_xs.  This moves those printks and
calculations into time_init just after the call to the platform's
calibrate_decr function.

Subject: powerpc/ppc/ppc64: Various compile fixes.

This declares powersave_nap in system.h and makes it an int everywhere,
fixes typos for the maple platform, fixes a couple of places where
I missed removing the last two arguments from a message_pass function,
and makes ppc64 consistent with ppc32 in the type of the
pci_bridge.cfg_data field.

In the merge tree, commit 0458060c1c59c5378d8fb5daabe18cf4681c35cd
broke boot on some machines because the initialization of conswitchp
was moved to arch/powerpc/kernel/setup_64.c, but a corresponding copy
was not added to arch/ppc64/kernel/setup.c.  This patch fixes it.

Subject: [PATCH] powerpc: Merge thread_info.h

Merge ppc32 and ppc64 versions of thread_info.h.  They were pretty
similar already, the chief changes are:

	- Instead of inline asm to implement current_thread_info(),
which needs to be different for ppc32 and ppc64, we use C with an
asm("r1") register variable.  gcc turns it into the same asm as we
used to have for both platforms.
	- We replace ppc32's 'local_flags' with the ppc64
'syscall_noerror' field.  The noerror flag was in fact the only thing
in the local_flags field anyway, so the ppc64 approach is simpler, and
means we only need a load-immediate/store instead of load/mask/store
when clearing the flag.
	- In readiness for 64k pages, when THREAD_SIZE will be less
than a page, ppc64 used kmalloc() rather than get_free_pages() to
allocate the kernel stack.  With this patch we do the same for ppc32,
since there's no strong reason not to.
	- For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE
via asm-offsets, thread_info.h can now be safely included in asm, as
on ppc32.

Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and
Power5 (ARCH=ppc64 and ARCH=powerpc).

Subject: ppc64/powerpc: Fix time initialization on SMP systems

This moves smp_space_timers from arch/ppc64/kernel/smp.c to
arch/powerpc/kernel/time.c and makes it initialize last_jiffy[]
instead of paca[].next_jiffy_update_tb, since last_jiffy[] is
now what the time code uses.  It also declares smp_space_timers
in include/asm-powerpc/time.h and gets rid of an ifdef in
div128_by_32.

Subject: ppc64: Rearrange btext initialization for consistency with ppc32

Moved init_boot_display from arch/ppc64/kernel/pmac_setup.c to
arch/ppc64/kernel/btext.c and declared it in asm-ppc64/btext.h.
Call it from init_early rather than pmac_init_early.

Subject: powerpc: Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.c

Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.c, update
the Makefiles to make it work, and make ARCH=ppc64 still work.

Michael's version put vio.c in arch/powerpc/sysedv but after consolting
Paulus, this one puts it in arch/powerpc/kernel.

Subject: powerpc: Merge i8259.c into arch/powerpc/sysdev

This changes the parameters for i8259_init so that it takes two
parameters: a physical address for generating an interrupt
acknowledge cycle, and an interrupt number offset.  i8259_init
now sets the irq_desc[] for its interrupts; all the callers
were doing this, and that code is gone now.  This also defines
a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and
makes the platforms that need it select that symbol.

Subject: powerpc: Merge rtas.c into arch/powerpc/kernel

This splits arch/ppc64/kernel/rtas.c into arch/powerpc/kernel/rtas.c,
which contains generic RTAS functions useful on any CHRP platform,
and arch/powerpc/platforms/pseries/rtas-fw.[ch], which contain
some pSeries-specific firmware flashing bits.  The parts of rtas.c
that are to do with pSeries-specific error logging are protected
by a new CONFIG_RTAS_ERROR_LOGGING symbol.  The inclusion of rtas.o
is controlled by the CONFIG_PPC_RTAS symbol, and the relevant
platforms select that.

From fda262b8978d0089758ef9444508434c74113a61 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Thu, 27 Oct 2005 20:20:42 +1000
Subject: [PATCH] ppc64: remove arch/ppc64/kernel/setup.c

and use setup_64.c from the merged tree instead.  The only difference
between them was the code to set up the syscall maps.

From 25c8a78b1e00ac0cc640677eda78b462c2cd4c6e Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Thu, 27 Oct 2005 16:27:25 +1000
Subject: [PATCH] powerpc: Fix handling of fpscr on 64-bit

The recent merge of fpu.S broken the handling of fpscr for
ARCH=powerpc and CONFIG_PPC64=y.  FP registers could be corrupted,
leading to strange random application crashes.

The confusion arises, because the thread_struct has (and requires) a
64-bit area to save the fpscr, because we use load/store double
instructions to get it in to/out of the FPU.  However, only the low
32-bits are actually used, so we want to treat it as a 32-bit quantity
when manipulating its bits to avoid extra load/stores on 32-bit.  This
patch replaces the current definition with a structure of two 32-bit
quantities (pad and val), to clarify things as much as is possible.
The 'val' field is used when manipulating bits, the structure itself
is used when obtaining the address for loading/unloading the value
from the FPU.

While we're at it, consolidate the 4 (!) almost identical versions of
cvt_fd() and cvt_df() (arch/ppc/kernel/misc.S,
arch/ppc64/kernel/misc.S, arch/powerpc/kernel/misc_32.S,
arch/powerpc/kernel/misc_64.S) into a single version in fpu.S.  The
new version takes a pointer to thread_struct and applies the correct
offset itself, rather than a pointer to the fpscr field itself, again
to avoid confusion as to which is the correct field to use.

Finally, this patch makes ARCH=ppc64 also use the consolidated fpu.S
code, which it previously did not.

Built for G5 (ARCH=ppc64 and ARCH=powerpc), 32-bit powermac (ARCH=ppc
and ARCH=powerpc) and Walnut (ARCH=ppc, CONFIG_MATH_EMULATION=y).
Booted on G5 (ARCH=powerpc) and things which previously fell over no
longer do.

Subject: [PATCH] powerpc: Purge bootinfo.h

With ARCH=powerpc we assume the presence of a device tree, so we don't
require any support for the old bi_recs method of passing boot
parameters.  Likewise, we've never needed it for ppc64, but we still
had an include/asm-ppc64/bootinfo.h from which nothing was used.  This
patch removes that file, and all references to it in arch/ppc64 and
arch/powerpc.  A related, unused variable 'boot_mem_size' is also
removed from setup_32.c.  The bootinfo stuff remains in ARCH=ppc for
the time being.

Built and booted on Power5 (ARCH=ppc64 and ARCH=powerpc), built for
32-bit powermac (ARCH=powerpc and ARCH=ppc).

Subject: ppc64: Use the correct prototypes for i8259 functions

We still had an old copy of i8259.h lying around; this gets rid of it
and corrects the callers of i8259_init and i8259_irq.

Subject: ppc64: use the merged syscall table

This allows us to also use entry_64.S from the merged tree and reverts
the setup_64.c part of fda262b8978d0089758ef9444508434c74113a61.

From 007e8f51b26ae7b6a17651af5a0f01ab6491cdca Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Fri, 28 Oct 2005 15:35:50 +1000
Subject: [PATCH] powerpc: Move xics.[ch] into platforms/pseries

This patch moves the XICS interrupt controller code into the
platforms/pseries directory, since it only appears on pSeries
machines.  If it ever appears on some other machine we can move it to
sysdev, although xics.c itself will need a bunch of changes in that
case to remove pSeries specific assumptions.

Subject: [PATCH] ppc: make phys_mem_access_prot() work with pfns instead of
 addresses

Change the phys_mem_access_prot() function to take a pfn instead of an
address.  This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures.  We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.

Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn.  Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.

Subject: [PATCH] TIOC* compat ioctl handling

TIOCSTART and TIOCSTOP are defined in asm/ioctls.h and asm/termios.h by
various architectures but not actually implemented anywhere but in the IRIX
compatibility layer, so remove their COMPATIBLE_IOCTL from parisc, ppc64
and sparc64.

Move the TIOCSLTC COMPATIBLE_IOCTL to common code, guided by an ifdef to
only show up on architectures that support it (same as the code handling it
in tty_ioctl.c), aswell as it's brother TIOCGLTC that wasn't handled so
far.

Subject: [PATCH] fix missing includes

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

Subject: powerpc: Fix bug arising from having multiple memory_limit variables

We had a static memory_limit in prom.c, and then another one defined
in setup_64.c and used in numa.c, which resulted in the kernel crashing
when mem=xxx was given on the command line.  This puts the declaration
in system.h and the definition in mem.c.  This also moves the
definition of tce_alloc_start/end out of setup_64.c.

From edf03c1ee84e5095e8f4a4b8ad6e0784118cb176 Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arndb@de.ibm.com>
Date: Mon, 31 Oct 2005 20:08:40 -0500
Subject: [PATCH] powerpc: move mmio_nvram.c over to arch/powerpc

The nvram code formally known as bpa_nvram.c is rather
generic really, so it is quite likely to be useful to
future boards not based on cell.

This patch puts it into arch/powerpc/sysdev.

Subject: [PATCH] powerpc: Merge bitops.h

Here's a revised version.  This re-introduces the set_bits() function
from ppc64, which I removed because I thought it was unused (it exists
on no other arch).  In fact it is used in the powermac interrupt code
(but not on pSeries).

- We use LARXL/STCXL macros to generate the right (32 or 64 bit)
  instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S

- ppc32 previously used a full "sync" barrier at the end of
  test_and_*_bit(), whereas ppc64 used an "isync".  The merged version
  uses "isync", since I believe that's sufficient.

- The ppc64 versions of then minix_*() bitmap functions have changed
  semantics.  Previously on ppc64, these functions were big-endian
  (that is bit 0 was the LSB in the first 64-bit, big-endian word).
  On ppc32 (and x86, for that matter, they were little-endian.  As far
  as I can tell, the big-endian usage was simply wrong - I guess
  no-one ever tried to use minixfs on ppc64.

- On ppc32 find_next_bit() and find_next_zero_bit() are no longer
  inline (they were already out-of-line on ppc64).

- For ppc64, sched_find_first_bit() has moved from mmu_context.h to
  the merged bitops.  What it was doing in mmu_context.h in the first
  place, I have no idea.

- The fls() function is now implemented using the cntlzw instruction
  on ppc64, instead of generic_fls(), as it already was on ppc32.

- For ARCH=ppc, this patch requires adding arch/powerpc/lib to the
  arch/ppc/Makefile.  This in turn requires some changes to
  arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc.

Built and running on G5.

Subject: [PATCH] powerpc: Move naca.h to platforms/iseries

These days, the NACA only exists on iSeries.  Therefore, this patch
moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries.
There was one file including naca.h outside of platforms/iseries -
arch/ppc64/kernel/udbg_scc.c.  However, that's obviously a hangover
from older days.  The include is not necessary, so this patch simply
removes it.

Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since
cell wants them as well as pseries (and chrp can use rtas-proc.c too,
at least in principle).  rtas_fw.c is gone, with its bits moved into
rtas_flash.c and rtas.c.

Subject: [PATCH] ppc64: Fix add notifier crashes

The extraction of PCI stuff from struct device_node left some false
assumptions in notifier code.  As a result, dynamic add crashes when
non-PCI nodes are added.  This patch fixes these assumptions.

There's no reason for smp_release_cpus() to be asm, and most people can make
more sense of C code. Add an extern declaration to smp.h and remove the custom
one in machine_kexec.c

Subject: powerpc: Merge smp.c and smp.h

This also moves setup_cpu_maps to setup-common.c (calling it
smp_setup_cpu_maps) and uses it on both 32-bit and 64-bit.
