x86: add MAP_STACK mmap flag

2008-08-15T18:45:19Z

as per this discussion: http://lkml.org/lkml/2008/8/12/423 Pardo reported that 64-bit threaded apps, if their stacks exceed the combined size of ~4GB, slow down drastically in pthread_create() - because glibc uses MAP_32BIT to allocate the stacks. The use of MAP_32BIT is a legacy hack - to speed up context switching on certain early model 64-bit P4 CPUs. So introduce a new flag to be used by glibc instead, to not constrain 64-bit apps like this. glibc can switch to this new flag straight away - it will be ignored by the kernel. If those old CPUs ever matter to anyone, support for it can be implemented. Signed-off-by: Ingo Molnar Acked-by: Ulrich Drepper Signed-off-by: Linus Torvalds

x86: consolidate header guards

2008-07-22T19:31:34Z

This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum

x86: unify include/asm/mman_32/64.h

2007-10-17T18:26:15Z

Same file, except for the extra 64bit MAP_32BIT define, which does not hurt for 32 bit compiles. Signed-off-by: Thomas Gleixner
