[PATCH] slab: fix handling of pages from foreign NUMA nodes
The numa slab allocator may allocate pages from foreign nodes onto the
lists for a particular node if a node runs out of memory. Inspecting the
slab->nodeid field will not reflect that the page is now in use for the
slabs of another node.
This patch fixes that issue by adding a node field to free_block so that
the caller can indicate which node currently uses a slab.
Also removes the check for the current node from kmalloc_cache_node since
the process may shift later to another node which may lead to an allocation
on another node than intended.
