This only appears to be a problem with strangely configured
cross-compilation ... native compilers don't have this issue.
But in the interests of helping others at least compile for
ia64, this can go in. -Tony

There are a few variants of the STACR register that affect more than
just the "AXON" version of EMAC. Replace the current test of various
chip models with tests for generic properties in the device-tree.

It's not like it really matters at this point since the system is
dying anyway, but handle_critical pushes too few registers on the
stack so the register dump, which makes the register dump look a bit
strange. This patch fixes it.

The current implementation of copy_to_user_page() gives "vaddr" to the
cache instruction when trying to sync the icache with the dcache. If
vaddr does not exist in the TLB, the CPU will silently abort the
operation, which may result in the caches staying out of sync.
To fix this, pass the "dst" parameter to flush_icache_range() instead
-- we know this is valid because we just wrote to it.

The current debug trap handling code does a number of things that are
illegal according to the AVR32 Architecture manual. Most importantly,
it may try to schedule from Debug Mode, thus clearing the D bit, which
can lead to "undefined behaviour".
It seems like this works in most cases, but several people have
observed somewhat unstable behaviour when debugging programs,
including soft lockups. So there's definitely something which is not
right with the existing code.
The new code will never schedule from Debug mode, it will always exit
Debug mode with a "retd" instruction, and if something not running in
Debug mode needs to do something debug-related (like doing a single
step), it will enter debug mode through a "breakpoint" instruction.
The monitor code will then return directly to user space, bypassing
its own saved registers if necessary (since we don't actually care
about the trapped context, only the one that came before.)
This adds three instructions to the common exception handling code,
including one branch. It does not touch super-hot paths like the TLB
miss handler.

Generate a new set of OCD register definitions in asm/ocd.h and rename
__mfdr() and __mtdr() to ocd_read() and ocd_write() respectively.
The bitfield definitions are a lot more complete now, and they are
entirely based on bit numbers, not masks. This is because OCD
registers are frequently accessed from assembly code, where bit
numbers are a lot more useful (can be fed directly to sbr, bfins,
etc.)
Bitfields that consist of more than one bit have two definitions:
_START, which indicates the number of the first bit, and _SIZE, which
indicates the number of bits. These directly correspond to the
parameters taken by the bfextu, bfexts and bfins instructions.

The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments. This normalizes them to a canonical
value similar to what EDK generates for most other devices. This is
needed to get ml300 support to compile in arch/ppc.

The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 broke the oprofile
configuration for MIPS by allowing oprofile support to be built for
kernel models where oprofile doesn't have a chance in hell to work.
Just a dependecy list on a number of architectures is - surprise - broken
and should as per past discussions probably in most considered to be
broken in most cases. So I introduce a dependency for the oprofile
configuration on ARCH_SUPPORTS_OPROFILE.

IRQ_PER_CPU had been OR-ed in, instead of set. This had been working
by accident for quite a while.

The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (sched: restore
deterministic CPU accounting on powerpc), unconditionally calls
update_process_tick() in system context. In the deterministic
accounting case this is the correct thing to do. However, in the
non-deterministic accounting case we need to not do this, since doing
this results in the time accounted as hardware irq time being
artificially elevated.
Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING'
checks in time.h into one for neatness.

Our automated test suite looks for keywords like error, fail, warning in
the boot log. In the case when the nmi watchdog is determined to be
stuck in check_nmi_watchdog(), none of those keywords are displayed.
This patch adds a keyword, "WARNING:", so it makes it easier to notice
when the nmi watchdog isn't working correctly. Also add a proper
KERN_WARNING mark to this printout.

The recent Kconfig changes in x86 resulted in CONFIG_X86_HT no longer
being set if (X86_32 && MK8).
After grep'ing through the tree I think the problem is that different
places have different assumptions about the semantics of CONFIG_X86_HT,
either:
- hyperthreading or
- multicore
This should be sorted out properly, but until then we should keep the
2.6.23 status quo.
