This breaks building on sparc64:
CC [M] drivers/infiniband/hw/mthca/mthca_provider.o
/build1/tduffy/openib-work/linux-2.6.11-openib/drivers/infiniband/hw/mthca/mthca_provider.c: In function `mthca_mmap_uar':
/build1/tduffy/openib-work/linux-2.6.11-openib/drivers/infiniband/hw/mthca/mthca_provider.c:352: warning: implicit declaration of function `pgprot_noncached'
/build1/tduffy/openib-work/linux-2.6.11-openib/drivers/infiniband/hw/mthca/mthca_provider.c:352: error: incompatible types in assignment
make[3]: *** [drivers/infiniband/hw/mthca/mthca_provider.o] Error 1
make[2]: *** [drivers/infiniband/hw/mthca] Error 2
make[1]: *** [_module_drivers/infiniband] Error 2
make: *** [_all] Error 2
This is ugly, but fixes the build. Perhaps sparc needs
pgprot_noncached() to be a noop?
