Subject: [PATCH V4 00/14] powerpc/mm/ppc64: Add 128TB support
Date: Thu, 16 Mar 2017 16:06:59 +0530 [thread overview]
Message-ID: <1489660633-24125-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
This patch series increase the effective virtual address range of
applications from 64TB to 128TB. We do that by supporting a
68 bit virtual address. On platforms that can only do 65 bit virtual
address we limit the max contexts to a 16bit value instead of 19.
The patch series also switch the page table layout such that we can
do 512TB effective address. But we still limit the TASK_SIZE to
128TB. This was done to make sure we don't break applications
that make assumption regarding the max address returned by the
OS. We can switch to 128TB without a linux personality value because
other architectures do 128TB as max address.
Changes from V3:
* Rebase to latest upstrea
* Fixes based on testing
Changes from V2:
* Handle hugepage size correctly.
