[BK-2.4 PATCH] Fix compile with highmem and highio

[Anton Altaparmakov]

Hi Marcelo,

Below patchlet is required to make your current bk tree compile with
highmem and highio enabled.

Please apply.

You can also get this changeset by doing a:

	bk pull http://linux-ntfs.bkbits.net/linux-2.4-kmapfix

Best regards,

	Anton

   Remove duplicate & bogus kmap_prot and kmap_pte exports.
   These are arch specific and only four architectures implement them. So
   on all other orchitectures with highmem enabled compilation would fail with
   these exports in ksyms.c... The architectures which need them already
   export them via their arch-ksyms files.

No, only these 4 architectures allow to set HIGHMEM. So no failure here.

No. They don't. At least in 2.4.20-pre4. I think they may be exported in
your tree, because of the ntfs backport patch.

Oops. You are right. I need to reclone a clean 2.4 tree. Mine has somehow 
managed to gain a few "extra" changesets. Ahem.

Sorry for the noise.
