[PATCH] bitops: use non atomic operations for minix_*_bit() and ext2_*_bit() · 67b0ad57

Akinobu Mita authored Mar 26, 2006

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.

[PATCH] bitops: alpha: use config options instead of __alpha_fix__ and __alpha_cix__ · 4b417d0c

Akinobu Mita authored Mar 26, 2006

Use config options instead of gcc builtin definition to tell the use of
instruction set extensions (CIX and FIX).

This is introduced to tell the kbuild system the use of opmized hweight*()
routines on alpha architecture.
