The p?d_page() methods still rely on highlevel types and methods:

In file included from arch/x86/kernel/early_printk.c:18:
/home/mingo/tip/arch/x86/include/asm/pgtable.h: In function ‘pmd_page’:
/home/mingo/tip/arch/x86/include/asm/pgtable.h:516: error: implicit declaration of function ‘__pfn_to_section’
/home/mingo/tip/arch/x86/include/asm/pgtable.h:516: error: initialization makes pointer from integer without a cast
/home/mingo/tip/arch/x86/include/asm/pgtable.h:516: error: implicit declaration of function ‘__section_mem_map_addr’
/home/mingo/tip/arch/x86/include/asm/pgtable.h:516: error: return makes pointer from integer without a cast

So convert them to macros and document the type dependency.

Impact: unify identical code

asm/io_32.h and _64.h have identical prototypes for the ioremap family
of functions.  The 32-bit header had a more descriptive comment.

Impact: unify identical code

asm/io_32.h and _64.h has functionally identical definitions for
virt_to_phys, phys_to_virt, page_to_phys, and the isa_* variants, so
just unify them.

The only slightly functional change is using phys_addr_t for the
physical address argument and return val.

The _none test is done differently for every level of the pagetable.
Standardize them by:

 1: Use the native_X_val to extract the raw entry, with no need to go
    via paravirt_ops, diff -r 1d0646d0d319 arch/x86/include/asm/pgtable.h, and
 2: Compare with 0 rather than using a boolean !, since they are actually values
    and not booleans.

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.
