#     powerpc/mm/hash: Increase vmalloc space with hash translation mode
#     
#     This patch updates the kernel non-linear virtual map size to 512TB
#     with 64K page size and hash translation mode. We allocate one context
#     for the vmalloc region and hence the max virtual area size is limited
#     by the context map size (512TB for 64K and 64TB for 4K page size).
#     
#     This patch fixes boot failures with large amounts of system RAM where
#     we need large vmalloc space to handle per cpu allocations.
