generic: implement __fls on all 64-bit archs

2008-04-26T17:21:16Z

Implement __fls on all 64-bit archs: alpha has an implementation of fls64. Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.

forbid asm/bitops.h direct inclusion

forbid asm/bitops.h direct inclusion Because of compile errors that may occur after bit changes if asm/bitops.h is included directly without e.g. linux/kernel.h which includes linux/bitops.h, forbid direct inclusion of asm/bitops.h.

alpha: lock bitops

Alpha can avoid one mb when acquiring a lock with test_and_set_bit_lock. [bunk@kernel.org: alpha bitops.h must #include ] Signed-off-by: Nick Piggin Cc: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Adrian Bunk Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

alpha: fix bitops

2007-10-18T21:37:29Z

Documentation/atomic_ops.txt defines these primitives must contain a memory barrier both before and after their memory operation. This is consistent with the atomic ops implementation on alpha.

bitops: introduce lock ops

2007-10-18T21:37:29Z

Introduce test_and_set_bit_lock / clear_bit_unlock bitops with lock semantics. Convert all architectures to use the generic implementation.

alpha: cleanup in bitops.h

2007-05-30T17:07:54Z

Remove 2 functions private to the alpha implemetation, in favor of similar functions in . Provide a more efficient version of the fls64 function for pre-ev67 alphas. Signed-off-by: Richard Henderson Signed-off-by: Linus Torvalds

- unless defined(__alpha_cix__) and defined(__alpha_fix__) - remove generic_fls() - remove generic_hweight{64,32,16,8}() - remove generic_fls64() - remove find_{next,first}{,_zero}_bit() - remove ext2_{set,clear,test,find_first_zero,find_next_zero}_bit() - remove minix_{test,set,test_and_clear,test,find_first_zero}_bit() Signed-off-by: Akinobu Mita Cc: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] bitops: alpha: use config options instead of __alpha_fix and alpha_cix__

2006-03-26T16:57:09Z

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.
