remove asm/bitops.h includes

including asm/bitops directly may cause compile errors. don't include it
and include linux/bitops instead. next patch will deny including asm header
directly.

pte_exec(), and pte_user() except where arch-specific code is making use of
them.

This patch is required to handle file-mapped or swapped-out pages
correctly.

- Fix pte_to_pgoff() and pgoff_to_pte() macros not to include
  _PAGE_PROTNONE bit of PTE.
  Mask value for { ACCESSED, N, (R, W, X), L, G } is not 0xef but 0x7f.
- Fix __swp_type() macro for MAX_SWAPFILES_SHIFT(=5), which is defined
  in include/linux/swap.h.

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE()
and GET_PFN() in pgtable.h.  However, the only callers of any of these
macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or
drivers/sbus.

This patch removes the redundant macros from all architectures except
sparc and sparc64.

One of the changes necessary for shared page tables is to standardize the
pxx_page macros.  pte_page and pmd_page have always returned the struct
page associated with their entry, while pte_page_kernel and pmd_page_kernel
have returned the kernel virtual address.  pud_page and pgd_page, on the
other hand, return the kernel virtual address.

Shared page tables needs pud_page and pgd_page to return the actual page
structures.  There are very few actual users of these functions, so it is
simple to standardize their usage.

Since this is basic cleanup, I am submitting these changes as a standalone
patch.  Per Hugh Dickins' comments about it, I am also changing the
pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

This patch removes page_pte_prot and page_pte macros from all
architectures.  Some architectures define both, some only page_pte (broken)
and others none.  These macros are not used anywhere.

page_pte_prot(page, prot) is identical to mk_pte(page, prot) and
page_pte(page) is identical to page_pte_prot(page, __pgprot(0)).

* The following architectures define both page_pte_prot and page_pte

  arm, arm26, ia64, sh64, sparc, sparc64

* The following architectures define only page_pte (broken)

  frv, i386, m32r, mips, sh, x86-64

* All other architectures define neither
