[ARM] fix fls() for 64-bit arguments

2008-07-26T14:23:25+00:00

arm's fls() is implemented as a macro, causing it to misbehave when passed
64-bit arguments.  Fix.

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.  Thanks to Adrian Bunk.

[ARM] 3852/1: convert atomic bitops and __xchg over to raw_local_irq_{save,restore}

2006-09-25T09:34:03+00:00

Thomas Gleixner noticed that bitops.h should also use the raw_* irq
disable/enable variants, and __xchg needs them as well.

[ARM] Add linux/compiler.h includes where required

2005-11-16T17:23:57+00:00

atomic.h, bitops.h and mmu_context.h are using likely/unlikely.
thread_info.h uses __attribute_const__.  Hence these files require
linux/compiler.h to be included.
