x86: partial unification of asm-x86/bitops.h This unifies the set/clear/test bit functions of asm/bitops.h. I have not attempted to merge the bit-finding functions, since they rely on the machine word size and can't be easily restructured to work generically without a lot of #ifdefs. In particular, the 64-bit code can assume the presence of conditional move instructions, whereas 32-bit needs to be more careful. The inline assembly for the bit operations has been changed to remove explicit sizing hints on the instructions, so the assembler will pick the appropriate instruction forms depending on the architecture and the context.

x86: revert commit 709f744 ("x86: bitops asm constraint fixes") 709f744 causes my computer to freeze during the start up of X and my login manger (GDM). It gets to the point where it has shown the default X mouse cursor logo (a big X / cross) and does not respond to anything from that point on. This worked fine before 709f744, and it works fine with 709f744 reverted on top of Linus' current tree (f74d505). The revert had conflicts, as far as I can tell due to white space changes. The diff I ended up with is below. It is 100% reproducible. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

x86: partial unification of asm-x86/bitops.h This unifies the set/clear/test bit functions of asm/bitops.h. I have not attempted to merge the bit-finding functions, since they rely on the machine word size and can't be easily restructured to work generically without a lot of #ifdefs. In particular, the 64-bit code can assume the presence of conditional move instructions, whereas 32-bit needs to be more careful.

x86: merge the simple bitops and move them to bitops.h Some of those can be written in such a way that the same inline assembly can be used to generate both 32 bit and 64 bit code. For ffs and fls, x86_64 unconditionally used the cmov instruction and i386 unconditionally used a conditional branch over a mov instruction. In the current patch I chose to select the version based on the availability of the cmov instruction instead. A small detail here is that x86_64 did not previously set CONFIG_X86_CMOV=y.

x86: merge the simple bitops and move them to bitops.h Some of those can be written in such a way that the same inline assembly can be used to generate both 32 bit and 64 bit code. For ffs and fls, x86_64 unconditionally used the cmov instruction and i386 unconditionally used a conditional branch over a mov instruction. In the current patch I chose to select the version based on the availability of the cmov instruction instead. A small detail here is that x86_64 did not previously set CONFIG_X86_CMOV=y. Improved comments for ffs, ffz, fls and variations. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86: partial unification of asm-x86/bitops.h This unifies the set/clear/test bit functions of asm/bitops.h. I have not attempted to merge the bit-finding functions, since they rely on the machine word size and can't be easily restructured to work generically without a lot of #ifdefs. In particular, the 64-bit code can assume the presence of conditional move instructions, whereas 32-bit needs to be more careful. The inline assembly for the bit operations has been changed to remove explicit sizing hints on the instructions, so the assembler will pick the appropriate instruction forms depending on the architecture and the context.

x86: finalize bitops unification include/asm-x86/bitops_32.h and include/asm-x86/bitops_64.h are now almost identical. The 64-bit version sets ARCH_HAS_FAST_MULTIPLIER and has an extra inline function set_bit_string. The define currently has no influence on the generated code, but it can be argued that setting it on i386 is the right thing to do anyhow. The addition of the extra inline function on i386 does not hurt either. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
