x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

x86: unify include/asm-x86/linkage_[32|64].h Remove definitions of FASTCALL/fastcall from linkage_32 as compiled with -regparm=3 by default since 2.6.20 and should no longer be needed. CONFIG X86_64 and CONFIG_X86_ALIGNMENT_16 are mutually exclusive as found in Kconfig.cpu so it should be fine to test them separately.

x86: shrink __ALIGN and __ALIGN_STR definitions Impact: cleanup 1) .p2align 4 and .align 16 are the same meaning (until a.out format for i386 is used which is not our case for CONFIG_X86_ALIGNMENT_16 anyway) 2) having 15 as max allowed bytes to be skipped does not make sense on modulo 16 Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> LKML-Reference: <20090309171951.GE9945@localhost> [ small cleanup, use __stringify(), etc. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86, tracing: add notrace to asm-x86/linkage.h notrace signals that a function should not be traced. Most of the time this is used by tracers to annotate code that cannot be traced - it's in a volatile state (such as in user vdso context or NMI context) or it's in the tracer internals.

x86: asm linkage - introduce GLOBAL macro If the code is time critical and this entry is called from other places we use ENTRY to have it globally defined and especially aligned. Contrary we have some snippets which are size critical. So we use plane ".globl name; name:" directive. Introduce GLOBAL macro for this.
