2008-11-23x86: introduce ENTRY(KPROBE_ENTRY)_X86 assembly helpers to catch unbalanced ↵Cyrill Gorcunov
declaration v3 Impact: make ENTRY()/END() macros more capable It's usefull to catch unbalanced or messed or mixed declarations of ENTRY and KPROBES. These macros would help a bit. For example the following code would compile without problems ENTRY_X86(mcount) retq END_X86(mcount) But if you forget and mess the following form ENTRY_X86(mcount) retq END(mcount) ENTRY_X86(ftrace_caller) The assembler will issue the following message: Error: ENTRY_X86/KPROBE_X86 unbalanced,missed,mixed Actually the checking is performed at every _X86 macro so maybe it's good idea to put ENTRY_KPROBE_FINAL_X86 at the end of .S file to be sure you didn't miss anything.

2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
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>
