Johannes Weiner e9ac829185 ARM: boolean bit testing
Bit testing (test, testset, testclear, testchange) for bit numbers
known at compile time returns a word with the tested-for bit set.

Change it to return a true boolean value so to make it consistent with
the out-of-line path and all the other bitops implementations.

Nicolas Pitre 94fc733664 [ARM] 5339/1: fix __fls() on ARM
Commit 0c65f459ce intended to fix truncation issues with fls() on
ARMv5+ by renaming it to __fls() and wrapping it into a C function.
However that didn't take into account the fact that __fls() already
already had different semantics in the kernel.

Let's move the __fls() code into fls() function directly, and redefine
__fls() with the appropriate semantics.  While at it, bring a generic
__fls() definition for pre ARMv5 too.

Russell King 4baa992243 [ARM] move include/asm-arm to arch/arm/include/asm
Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.
