5b17e1cd89 asm-generic: rename page.h and uaccess.h
The current asm-generic/page.h only contains the get_order
function, and asm-generic/uaccess.h only implements
unaligned accesses. This renames the file to getorder.h
and uaccess-unaligned.h to make room for new page.h
and uaccess.h file that will be usable by all simple
(e.g. nommu) architectures.

54321d947a x86: move pte types into pgtable*.h
pgtable*.h is intended for definitions relating to actual pagetables
and their entries, so move all the definitions for
(pte|pmd|pud|pgd)(val)?_t to the appropriate pgtable*.h headers.

c47c1b1f3a x86, pgtable.h: fix 2-level 32-bit build
- pmd_flags() needs to be available on 2-levels too
- provide pud_large() wrapper as well
- include page.h - it provides basic types relied on by pgtable.h

18a7a199f9 x86: add and use pgd/pud/pmd_flags
Add pgd/pud/pmd_flags which are analogous to pte_flags, and use them
where-ever we only care about testing the flags portions of the
respective entries.

ab897d2013 x86/pvops: remove pte_flags pvop
pte_flags() was introduced as a new pvop in order to extract just the
flags portion of a pte, which is a potentially cheaper operation than
extracting the page number as well.  It turns out this operation is
not needed, because simply using a mask to extract the flags from a
pte is sufficient for all current users.

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.
