Include acle-compat.h directly rather than getting it via sysreg.h.
Add new code to read and parse cpu identification data using the new CPUID mechanism defined for armv7.
Add new TLB and cache maintainence functions for armv6 and armv7.
Eliminate an unused macro whose name clashes now with a function in the new cpu-v6.h
Add cache maintenance functions which will be used by startup code to initially set up the MMU.
Fix a "decl is not a prototype" error noticed by gcc (but not clang).
Update comments (r4 is not used anywhere), use non-profiling entry macros.
Add arm option ARM_NEW_PMAP, to allow us to begin adding the new pmap code alongside the existing implementation
Add armv6 implementations of cache operations to avoid duplication

Remove _PROF_PROLOGUE from the EENTRY() macros.
Stylish changes... put tabs where they need to be in macros, move lines around so that related things are more grouped together, rewrite comments.
Fix the GLOBAL macro so it works (upper vs lowercase X), use it in _EENTRY.
Create 'L' variants of all the ENTRY macros for file-static/local symbols.

Clean up our ARM assembly:
MFC 275256:
Switch to the ARM unified assembly language as the clang integrated as only supports it. Binutils supports it when the ".syntax unified" directive is set.
Sponsored by: ABT Systems Ltd
MFC 275264:
Update _ENTRY to use _EENTRY to reduce the common code.
MFC 275321:
Remove extra labels, ENTRY_NP already provides them.
Sponsored by: ABT Systems Ltd
MFC 275322:
Correctly a few incorrect uses of ENTRY/EENTRY and END/EEND
Sponsored by: ABT Systems Ltd
MFC 275416:
Fix the name of the coprocessor to include the "p" prefix, the clang integrated assembler expects this.
Sponsored by: ABT Systems Ltd
MFC 275418:
Switch to unified syntax so these can be built with clang 3.5.
Sponsored by: ABT Systems Ltd
MFC 275519:
Add missing END macros to some of the xscale functions.
Sponsored by: ABT Systems Ltd
MFC 275520:
Use the unified syntax in a few more assembly files
Sponsored by: ABT Systems Ltd
MFC 275521:
Set the alignment to 4-bytes after a string as clang 3.5 can switch to thumb mode if this is incorrect.
Sponsored by: ABT Systems Ltd
MFC 275522:
Place the literal pool after a RET otherwise clang 3.5 tries to put it too far away from a ldr psuedo instruction. With this clang will place the literal value here where it's close enough to be loaded.

MFC 275523:
Switch to an armv6k cpu, without this clang 3.5 complains "bx lr" is unsupported as it needs a newer cpu.
Sponsored by: ABT Systems Ltd
MFC 275524:
Switch to a .cpu directive. These will work when clang 3.5 is imported where the .arch directive is a nop.

MFC r270882, r270930:
In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo). The EABI unwind info requires a .fnend for every .fnstart, and newer binutils will complain about seeing two .fnstart in a row. This change allows newer tools to compile our code.
Do not generate unwind info in asm functions if _STANDALONE is defined. The .fnend op causes the assembler to emit RELOC references to unwind support functions that don't exist in libstand.
