[PATCH] x86-64: Fix wrong gcc check in bitops.h

2007-02-13T12:26:25Z

gcc 5.0 will likely not have the constraint problem Signed-off-by: Andi Kleen

[PATCH] x86-64: Use different constraint for gcc < 4.1 in bitops.h

2007-01-11T00:52:44Z

+m is really correct for a RMW instruction, but some older gccs error out. I finally gave in and ifdefed it. This fixes compilation errors with some compiler version. Signed-off-by: Andi Kleen

[PATCH] optimize hweight64 for x86_64

2006-09-26T08:52:38Z

Based on patch from David Rientjes , but changed by AK. Optimizes the 64-bit hamming weight for x86_64 processors assuming they have fast multiplication. Uses five fewer bitops than the generic hweight64. Benchmark on one EMT64 showed ~25% speedup with 2^24 consecutive calls. Define a new ARCH_HAS_FAST_MULTIPLIER that can be set by other architectures that can also multiply fast. Signed-off-by: Andi Kleen

[PATCH] x86_64: x86_64 version of the smp alternative patch.

2006-06-26T17:48:14Z

Changes are largely identical to the i386 version: * alternative #define are moved to the new alternative.h file. * one new elf section with pointers to the lock prefixes which can be nop'ed out for non-smp. * two new elf sections simliar to the "classic" alternatives to replace SMP code with simpler UP code. * fixup headers to use alternative.h instead of defining their own LOCK / LOCK_PREFIX macros. The patch reuses the i386 version of the alternatives code to avoid code duplication. The code in alternatives.c was shuffled around a bit to reduce the number of #ifdefs needed. It also got some tweaks needed for x86_64 (vsyscall page handling) and new features (noreplacement option which was x86_64 only up to now). Debug printk's are changed from compile-time to runtime.
