Subject: [GIT PULL] core/mm changes for v5.2: Unify TLB flushing across architectures
Date: Mon, 6 May 2019 08:57:46 +0200 [thread overview]
Message-ID: <20190506065746.GA105888@gmail.com> (raw)
Linus,
Please pull the latest core-mm-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-mm-for-linus
# HEAD: f6c6010a07734103a31faa0cc977641b358c45b0 mm/resource: Use resource_overlaps() to simplify region_intersects()
This tree contains the generic mmu_gather feature from Peter Zijlstra,
which is an all-arch unification of TLB flushing APIs, via the following
(broad) steps:
- enhance the <asm-generic/tlb.h> APIs to cover more arch details
- convert most TLB flushing arch implementations to the generic
<asm-generic/tlb.h> APIs.
- remove leftovers of per arch implementations
After this series every single architecture makes use of the unified TLB
flushing APIs.
Thanks,
Ingo
