• 22a9835c3   [PATCH] unify PFN_* macros ... Browse Code »

  Just about every architecture defines some macros to do operations on pfns.
  They're all virtually identical. This patch consolidates all of them.

  One minor glitch is that at least i386 uses them in a very skeletal header
  file. To keep away from #include dependency hell, I stuck the new
  definitions in a new, isolated header.

  Of all of the implementations, sh64 is the only one that varied by a bit.
  It used some masks to ensure that any sign-extension got ripped away before
  the arithmetic is done. This has been posted to that sh64 maintainers and
  the development list.

  Compiles on x86, x86_64, ia64 and ppc64.
