| | | | | | | | | Increase max addressable range to 64TB. This is not tested on real hardware yet. Reviewed-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc/mm: Fix typo in PTRS_PER_PUDScott Wood2012-09-171-1/+1
| | | | | | | | | | PTRS_PER_PUD should be based on PUD_INDEX_SIZE, not PMD_INDEX_SIZE. We got away with it because PUD and PMD had the same index size, but this is no longer true with Aneesh's patchset to support a 46-bit user effective address space.

* powerpc/mm: Split the various pgtable-* headers based on MMU typeBenjamin Herrenschmidt2009-03-201-0/+74
This patch moves the definition of the PTE format for each MMU type to separate files instead of all in one file. This improves overall maintainability and will make it easier to add new types. On 64-bit, additionally, I've separated the headers relative to the format of the page table tree (3 vs. 4 levels for 64K vs 4K pages) from the headers specific to the PTE format for hash based processors, this will make it easier to add support for Book3 "E" 64-bit implementations. There are still some type-related ifdef's in the generic headers, we might remove them in the long run, but this patch shouldn't result in any code change, -hopefully- just definitions being moved around.
