[MIPS] Fix bitops for MIPS32/MIPS64 CPUs.

2006-04-27T14:13:49+00:00

    
With recent rewrite for generic bitops, fls() for 32bit kernel with
MIPS64_CPU is broken.  Also, ffs(), fls() should be defined the same
way as the libc and compiler built-in routines (returns int instead of
unsigned long).

[PATCH] bitops: use non atomic operations for minix__bit() and ext2__bit()

2006-03-26T16:57:10+00:00

Bitmap functions for the minix filesystem and the ext2 filesystem except
ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic
guarantees.

But these are defined by using atomic bit operations on several architectures.
 (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc,
sparc64, v850, and xtensa)

This patch switches to non atomic bit operation.

[MIPS] Cleanup fls implementation.

2006-02-07T13:30:24+00:00

    
fls was the only called of flz, so fold flz into fls, same for the
__ilog2 call.  Delete the now unused flz function.
