Subject: [PATCH v4 0/4] shoot lazy tlbs
Date: Sat, 5 Jun 2021 11:42:12 +1000 [thread overview]
Message-ID: <20210605014216.446867-1-npiggin@gmail.com> (raw)
The additional unused config option was a valid criticism, so this now
purely just toggles refcounting of the lazy tlb mm.
Thanks,
Nick
Since v3:
- Removed the extra config option, MMU_LAZY_TLB=n. This can be
resurrected if an arch wants it.
Nicholas Piggin (4):
lazy tlb: introduce lazy mm refcount helper functions
lazy tlb: allow lazy tlb mm refcounting to be configurable
lazy tlb: shoot lazies, a non-refcounting lazy tlb option
powerpc/64s: enable MMU_LAZY_TLB_SHOOTDOWN
