c4c4688f72 x86: UV BAU messaging timeouts 
This patch replaces a 'nop' uv_enable_timeouts() in the
UV TLB shootdown code. (somehow, long ago that function got
eviscerated)

If any cpu in the destination node does not get interrupted by the
message and post completion in a reasonable time the hardware
should respond to the sender with an error.  This function
enables such timeouts.

Tested on the UV hardware simulator.

05e4d3169b x86: drop double underscores from header guards 
Drop double underscores from header guards in arch/x86/include.  They
are used inconsistently, and are not necessary.

1965aae3c9 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.
