For x86 this affected highmem pages only, since they were always kmapped cache-coherent, and this is fixed using kmap_atomic_prot(). For other architectures that may not modify the linear kernel map we resort to vmap() for now, since kmap_atomic_prot() generally uses the linear kernel map for lowmem pages. This of course comes with a performance impact and should be optimized when possible. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com> |
