Avoid false positive warnings in kmap_atomic_prot() with DEBUG_HIGHMEM
I believe http://bugzilla.kernel.org/show_bug.cgi?id=10318 is a false positive. There's no way in which networking will be using highmem pages here, so it won't be taking the KM_USER0 kmap slot, so there's no point in performing these checks.

Miller" <davem@davemloft.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> [ Really sad. We lose almost all real-life coverage of the debug tests with this patch. Now it will only report problems for the cases where people actually end up using a HIGHMEM page, not when they just _might_ use one. - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
