5411be59db [PATCH] drop task argument of audit_syscall_{entry,exit}
... it's always current, and that's a good thing - allows simpler locking.

ee1cca1b06 [MIPS] Fix branch emulation for floating-point exceptions.
In the branch emulation for floating-point exceptions, __compute_return_epc
must determine for bc1f et al which condition code bit to test. This is
based on bits <4:2> of the rt field. The switch statement to distinguish
bc1f et al needs to use only the two low bits of rt, but the old code tests
on the whole rt field.  This patch masks off the proper bits.

2a2c3e4519 [MIPS] Sparse: fix sparse for 64-bit kernels.
This commit breaks sparse for 64bit kernel.  The -m64 option is
required.  Also, some macro values (such as _MIPS_TUNE, etc.)  contain
double-quote characters so it would be better quoting arguments by
single-quote characters.

6f8782c4b2 [MIPS] Use __ffs() instead of ffs() in ip32_irq0().
With recent rewrite for generic bitops, ffs() is defined the same way
as the libc and compiler built-in routines (returns int instead of
unsigned long).  Use __ffs() for 64bit value.

6ad0013b31 [PATCH] fix mips sys32_p{read,write}
Switched to use of sys_pread64()/sys_pwrite64() rather than keep duplicating
their guts; among the little things that had been missing there were such as
	ret = security_file_permission (file, MAY_READ);
Gotta love the LSM robustness, right?

9200c0b2a0 [MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2.
This fixes kernel builds with gcc 3.2 (not 64-bit, that is looking like
it is beyond recovery) and 3.3.  With these bugs fixed we now also can
get undo 3b4c4996a0c24da9e6f8be764e3950b756b18cc0 and similar bits for

e4ac58afdf [MIPS] Rewrite all the assembler interrupt handlers to C.
Saves like 1,600 lines of code, is way easier to debug, compilers
frequently do a better job than the cut and paste type of handlers many
boards had.  And finally having all the stuff done in a single place
also means alot of bug potencial for the MT ASE is gone.

The only surviving handler in assembler is the DECstation one; I hope
Maciej will rewrite it.
