In order for CPUidle to work on SMP systems, an implementation of
cpu_idle_wait() is needed.
This patch duplicates the x86 implementation of cpu_idle_wait() for

Do this by adding flush_icache_all to cache_fns for ARMv6 and 7.
As flush_icache_all may neeed to be called from flush_kern_cache_all,
add it as the first entry in the cache_fns.
Note that now we can remove the ARM_ERRATA_411920 dependency
to !SMP so it can be selected on UP ARMv6 processors, such
as omap2.

UP systems do not implement all the instructions that SMP systems have,
so in order to boot a SMP kernel on a UP system, we need to rewrite
parts of the kernel.
Do this using an 'alternatives' scheme, where the kernel code and data
is modified prior to initialization to replace the SMP instructions,
thereby rendering the problematical code ineffectual. We use the linker
to generate a list of 32-bit word locations and their replacement values,
and run through these replacements when we detect a UP system.

All platforms which currently support SMP also support the ARM SCU
and ARM TWD blocks, so it's pointless to make these config symbols
conditional on the platform symbols which SMP is already conditional
on.

Provide a mechanism that allows running code in IRQ context. It is
most useful for NMI code that needs to interact with the rest of the
system -- like wakeup a task to drain buffers.
Perf currently has such a mechanism, so extract that and provide it as
a generic feature, independent of perf so that others may also
benefit.
The IRQ context callback is generated through self-IPIs where
possible, or on architectures like powerpc the decrementer (the
built-in timer facility) is set to generate an interrupt immediately.
Architectures that don't have anything like this get to do with a
callback from the timer tick. These architectures can call
irq_work_run() at the tail of any IRQ handlers that might enqueue such
work (like the perf IRQ handler) to avoid undue latencies in
processing the work.

data corruption
On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption
can occur under very rare conditions due to a store buffer optimisation.
This workaround sets a bit in the diagnostic register of the Cortex-A9,
disabling the optimisation and preventing the problem from occurring.

corruption
On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption
can occur if a shared cache line is replaced on one CPU as another CPU
is accessing it.
This workaround sets two bits in the diagnostic register of the Cortex-A9,
reducing the linefill issuing capabilities of the processor and
avoiding the erroneous behaviour.

On versions of the Cortex-A9 up to and including r2p2, under rare
circumstances, a DMB instruction between 2 write operations may not
ensure the correct visibility ordering of the 2 writes.
This workaround sets a bit in the diagnostic register of the Cortex-A9,
causing the DMB instruction to behave like a DSB, which functions
correctly on the affected cores.

faulty ASID
On versions of the Cortex-A9 prior to r2p0, performing TLB invalidations by
ASID match can result in the incorrect ASID being broadcast to other CPUs.
As a consequence of this, the targetted TLB entries are not invalidated
across the system.
This workaround changes the TLB flushing routines to invalidate entries
regardless of the ASID.

v2: fixes from Russell King:
- include linux/io.h instead of asm/io.h
- fix whitespace in Kconfig
- Use spin_lock_init to initialize lock
- Return -ENOSYS instead of BUG for unimplemented clock ops
- Use proper return values in tegra2 clock ops
additional changes:
- Rename some clocks to match dev_ids
- add rate propagation
- add debugfs entries
- add support for clock listed in clk_lookup under multiple dev_ids
v3:
- Replace per-clock locking with global clock lock
- Autodetect clock state on init
- Let clock dividers pick next lower possible frequency
- Add support for clock init tables
- Minor bug fixes
- Fix checkpatch issues

Trivial conflicts in Documentation/feature-removal-schedule.txt

Now that all arches have been converted over to use generic time via
clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME
config option and simplify the generic code.

As long as the zImage is placed within the 128MB range from the start of
memory, ZRELADDR (Address where the decompressed kernel will be placed,
usually == PHYS_OFFSET + TEXT_OFFSET) can be determined at run-time by
masking PC with 0xf80000000.
Running through all the Makefile.boot, all those zreladdr-y
addresses == 0x[0-f][08]00_0000 + TEXT_OFFSET can be determined at
run-time.
Option CONFIG_AUTO_ZRELADDR and CONFIG_ZRELADDR are introduced,
CONFIG_ZRELADDR _must_ be explicitly specified if:
- ((zreladdr-y - TEXT_OFFSET) & ~0xf8000000) != 0, which means
masking PC with 0xf8000000 will result in an incorrect address.
Currently this is only a problem on u300.
- or the assumption of the zImage being loaded by the bootloader within
the first 128MB of RAM is incorrect
- or when ZBOOT_ROM is used, where the above assumption is usually wrong.
[ukleinek: changed mask from 0xf0000000 to 0xf8000000 for mx1 and shark
+ some review fixes from the mailing list]

This was deprecated in 2001 and announced to live on for 5 years.
For now provide a kernel parameter for those who still need it.
