[PATCH 1/2] powerpc/mm: fix up pgtable dump flags

[Oliver O'Halloran]

On Book3s we have two PTE flags used to mark cache-inhibited mappings:
_PAGE_TOLERANT and _PAGE_NON_IDEMPOTENT. Currently the kernel page
table dumper only looks at the generic _PAGE_NO_CACHE which is
defined to be _PAGE_TOLERANT. This patch modifies the dumper so
both flags are shown in the dump.
