Crestone Peak Slow is the 800MHz PA-8800 cpu in the C8000.
0x88B is probably the Crestone Peak Fast.

When we show_regs, we obviously have a struct pt_regs of the calling
frame. Use these in show_stack so we don't have the entire bogus call trace
up to the show_stack call.

This patch adds the known pa8900 CPUs to the inventory list and removes
the Crestone Peak one which apparently never escaped into the wild.

Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug
by accidently removing the "static" from iodc_dbuf. This resulted in, what
appeared to be, a trap without *current set to a task. Probably the result of
a trap in real mode while calling firmware.
Also do other misc clean ups. Since the only input from firmware is non
blocking, share iodc_dbuf between input and output, and spinlock the
only callers.

Originally, show_stack was used in BUG() output. However, a recent commit
changed it to print register state (no idea what that's supposed to help,
really...) and parisc was missing a backtrace because of it.

iommu_is_span_boundary in lib/iommu-helper.c was exported for PARISC IOMMUs
(commit 3715863aa142c4f4c5208f5f3e5e9bac06006d2f). Alpha's IOMMU can use it.
This removes the check on the boundary size alignment because
iommu_is_span_boundary does.

This allows monitoring compile issues with Kautobuild for
other omap1 boards until we have more board specific defconfig
files.
After 2.6.25, we can add a generic config_omap_generic16xx to
compile in support for all 16xx boards and then remove other
boards from OSK defconfig.

locks can be aquired in both irq and non-irq contexts, they need

H2 and H3 were broken on by e27a93a944a5ba6a0112750c8243abba86d56e94,
which removed declarations for their tps6501x chips. This resolves
that issue for the H2. (Note that this patch *also* broke the isp1301
support on H2; it presumed a not-yet-merged new-style I2c driver.)

Get rid of build warnings and errors in mainline for H3 boards; not
all the H3 updates were correct, it seems like the OMAP1 boards are
not getting proper build testing.
Also, commit e27a93a944a5ba6a0112750c8243abba86d56e94 introduced a
regression related to the tps65013 chip.

Remove false lockdep warnings about lock recursion when declaring
IRQs as being wake-capable, by marking putting GPIO irq_desc locks
into their own class.
(Thanks to Peter Zijlstra for helping track down such a small
fix to this problem.)

The DNS-323, Kurobox-Pro / Linkstation-Pro, QNAP TS-109/TS-209 and some
other orion-based systems have several bogus memory entries in the tag
table, which causes the system to crash at startup. Ignore them by
resetting the tag ID to 0 in a machine fixup function.

My recent hack to allocate the hash table under 1GB on cell was poorly
tested, *cough*. It turns out on blades with large amounts of memory we
fail to allocate the hash table at all. This is because RTAS has been
instantiated just below 768MB, and 0-x MB are used by the kernel,
leaving no areas that are both large enough and also naturally-aligned.
For the cell IOMMU hack the page tables must be under 2GB, so use that
as the limit instead. This has been tested on real hardware and boots
happily.

Subject: Export empty_zero_page
The empty_zero_page symbol is exported by most other architectures
(s390, ia64, x86, um), and an upcoming ext4 patch needs it because
ZERO_PAGE() references empty_zero_page, and we need it to zero out an
unitialized extents in ext4 files.

A bogus test for unassigned resources that came from our 32-bit
PCI code ended up being "merged" by my previous patch series,
breaking some 64-bit setups where devices have legal resources
ending at 0xffffffff.
This fixes it by completely changing the test. We now test for
res->start == 0, as the generic code expects, and we also only
do so on platforms that don't have the PPC_PCI_PROBE_ONLY flag
set, as there are cases of pSeries and iSeries where it could
be a valid value and those can't reassign devices.

The pattern substitution rules were failing when used with zImage-dtb
targets. If zImage-dtb.initrd was selected, the pattern substitution
would generate "zImage.initrd-dtb" instead of "zImage-dtb.initrd" which
caused the build to fail.
This renames zImage-dtb to dtbImage to avoid the problem entirely.
By not using the zImage prefix then is no potential for namespace
collisions.

Some drivers (such as V4L2) have code that causes gcc to generate
calls to __ucmpdi2 when compiling for 32-bit powerpc, which results
in either a link-time error or a module that can't be loaded, as
we don't currently have a __ucmpdi2. This adds one so these drivers
can be used.

At present, we can hit the BUG_ON in __spu_update_sched_info by reading
the regs file of a context between two calls to spu_run. The
spu_release_saved called by spufs_regs_read() is resulting in the (now
non-runnable) context being placed back on the run queue, so the next
call to spu_run ends up in the bug condition.
This change uses the SPU_SCHED_SPU_RUN flag to only reschedule a context
if it's still in spu_run().

commit 4ef11014 introduced a usage of SCHED_IDLE to detect when
a context is within spu_run.
Instead of SCHED_IDLE (which has other meaning), add a flag to
sched_flags to tell if a context should be running.

Not all e300 cores support the performance monitors, and the ones
that don't will be confused by the mf/mtpmr instructions. This
allows the support to be optional, so the 8349 can turn it off
while the 8379 can turn it on. Sadly, those aren't config options,
so it will be left to the defconfigs and the users to make that
determination.
