[PATCH] Fix 'make headers_check' for Alpha

Browse Source 
Alpha currently fails 'make headers_check' in the 2.6.18-rc kernels.  This
patch fixes it, by moving the existing #ifdef __KERNEL__ in asm/page.h so that
it covers everything that userspace shouldn't so, and by adding asm/compiler.h
to the list of exported files so that its use within asm/byteorder.h is
successful.

[ Note that at least with GCC 4, <linux/compiler.h> doesn't do the forced
  inlining about which there are nasty comments (and a workaround) in
  <asm/compiler.h>, unless you set CONFIG_FORCED_INLINING.  Rather than keep
  the mess you have in <asm/compiler.h> you could perhaps just make sure
  CONFIG_FORCED_INLINING=n is also honoured with GCC3, and make sure it cannot
  be set for Alpha? ]
