[OpenAFS-devel] Another build problem on sparc-linux

[Dean Anderson]

In the libafs tree '../linux/highmem.h' points to
'/usr/src/linux2.4/linux/highmem.h', which includes 'asm/highmem.h'.

On sparc, asm is a link to asm-sparc or asm-sparc64, in the linux source
tree, depending on architecture.

The asm-sparc version of highmem.h includes asm/kmap_types.h, which has
the definitions needed.

The asm-sparc64 version of highmem.h doen't include kmap_types.h, nor does
it directly access asm-sparc.

It looks like a (simple enough) kernel bug in the sparc linux 2.4 kernel
source, except that I'm wondering why no one else has this problem... Most
distributions don't muck with the kernel sources too much.
