Unify arch/x86/mm/Makefile between 32 and 64 bits.
All configuration variables that are protected by Kconfig constraints
have been put in the common part of the Makefile; however, the NUMA
files are totally different between 32 and 64 bits and are handled via
an ifdef.

change_page_attr_add is only used in pageattr.c now, so we can
make this function static.
change_page_attr() isn't used anywere at all anymore; this function
is a really bad API anyway so just remove the bloat entirely.

Since change_page_attr() is tricky code it is good to have some regression
test code. This patch maps and unmaps some random pages in the direct mapping
at boot and then dumps the state and does some simple sanity checks.
Add it with a CONFIG option.

Introduce fixup_exception() on 64-bit and use it in kprobes to
eliminate an #ifdef.
Only 64-bit needs search_extable() due to a stepping bug.

mmap_is_ia32 always true for X86_32, or while emulating IA32 on X86_64
Randomization not supported on X86_32 in legacy layout. Both layouts allow
randomization on X86_64.
