Subject: [PATCH V3 0/3] Add support for 4PB virtual address space on hash
Date: Wed, 7 Mar 2018 10:12:01 +0530 [thread overview]
Message-ID: <20180307044204.8904-1-aneesh.kumar@linux.vnet.ibm.com> (raw)
This patch series extended the max virtual address space value from 512TB
to 4PB with 64K page size. We do that by allocating one vsid context for
each 512TB range. More details of that is explained in patch 3.
Changes from V2:
* Rebased on top of slice_mask series from Nick Piggin
* Fixed segfault when mmap with 512TB hint address
Aneesh Kumar K.V (3):
powerpc/mm: Add support for handling > 512TB address in SLB miss
powerpc/mm/hash64: Increase the VA range
powerpc/mm/hash: Don't memset pgd table if not needed
