ccef086454 x86, mm: Correct the implementation of is_untracked_pat_range()
The semantics the PAT code expect of is_untracked_pat_range() is "is
this range completely contained inside the untracked region."  This
means that checkin 8a27138924 was
technically wrong, because the implementation needlessly confusing.

The sane interface is for it to take a semiclosed range like just
about everything else (as evidenced by the sheer number of "- 1"'s
removed by that patch) so change the actual implementation to match.

65f116f5f1 x86: Change is_ISA_range() into an inline function
Change is_ISA_range() from a macro to an inline function.  This makes
it type safe, and also allows it to be assigned to a function pointer
if necessary.

6b18ae3e2f x86: Move memory_setup to x86_init_ops
memory_setup is overridden by x86_quirks and by paravirts with weak
functions and quirks. Unify the whole mess and make it an
unconditional x86_init_ops function which defaults to the standard
function and can be overridden by the early platform code.

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.
