Alexander van Heukelum e407d62088 x86, traps: introduce dotraplinkage
Mark the exception handlers with "dotraplinkage" to hide the
calling convention differences between i386 and x86_64.

Alexander van Heukelum a28680b4b8 x86, traps: split out math_error and simd_math_error
Split out math_error from do_coprocessor_error and simd_math_error
from do_simd_coprocessor_error, like on i386. While at it, add the
"error_code" parameter to do_coprocessor_error, do_simd_coprocessor_error
and do_spurious_interrupt_bug.

This does not change the generated code, but brings the declarations in
line with all the other trap handlers.

Srinivasa Ds da654b74bd signals: demultiplexing SIGTRAP signal
Currently a SIGTRAP can denote any one of below reasons.
	- Breakpoint hit
	- H/W debug register hit
	- Single step
	- Signal sent through kill() or rasie()

Architectures like powerpc/parisc provides infrastructure to demultiplex
SIGTRAP signal by passing down the information for receiving SIGTRAP through
si_code of siginfot_t structure. Here is an attempt is generalise this
infrastructure by extending it to x86 and x86_64 archs.

Jaswinder Singh 70ef56414e x86: mm/fault.c declare do_page_fault before they get used
declared do_page_fault() in asm-x86/trap.h for both X86_32 and X86_64

removed do_invalid_op declaration from mm/fault.c as it is already declared in asm-x86/trap.h

Vegard Nossum 77ef50a522 x86: consolidate header guards
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.
