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.

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.
