This makes the range reservation feature available to other
architectures.
-v2: add get_max_mapped, max_pfn_mapped only defined in x86...
to fix PPC compiling
-v3: according to hpa, add CONFIG_HAVE_EARLY_RES
-v4: fix typo about EARLY_RES in config

Makes early_res.c more clean, so later could move it to /kernel.

Finally we can use early_res to replace bootmem for x86_64 now.
Still can use CONFIG_NO_BOOTMEM to enable it or not.

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 8a27138924f64d2f30c1022f909f74480046bc3f 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.

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.

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.

Impact: cleanup
This fixed various signedness issues in setup.c and e820.c:

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.
