Something in recent linux-next kernels caused linux/highmem.h to
no longer be included implicitly from o2iblnd_cb.c, causing a build
failure:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c: In function 'kiblnd_kvaddr_to_page':
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:549:15: error: 'PKMAP_BASE' undeclared (first use in this function); did you mean 'RTM_BASE'?
if (vaddr >= PKMAP_BASE &&
^~~~~~~~~~
RTM_BASE
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:549:15: note: each undeclared identifier is reported only once for each function it appears in
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:550:28: error: 'LAST_PKMAP' undeclared (first use in this function); did you mean 'AT_HWCAP'?
vaddr < (PKMAP_BASE + LAST_PKMAP * PAGE_SIZE)) {
^~~~~~~~~~
AT_HWCAP
This adds back an explicit include for the header.

Thanks for finding and fixing this. I did recently reduce the number
of include files that were automatically included everywhere. Clearly
some config combinations didn't get tested properly.
