Subject: [RFC PATCH 0/5] Add support for 4PB virtual address space on hash
Date: Sat, 10 Feb 2018 16:26:38 +0530 [thread overview]
Message-ID: <20180210105643.11857-1-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 4.
Aneesh Kumar K.V (5):
powerpc: Don't do runtime futex_cmpxchg test
powerpc/mm/slice: Update documentation in the file.
powerpc/mm/slice: Reduce the stack usage in slice_get_unmapped_area
powerpc/mm: Add support for handling > 512TB address in SLB miss
powerpc/mm/hash64: Increase the VA range
