Subject: [PATCH 0/8] x86/mm/cpa: Further optimizations
Date: Wed, 19 Sep 2018 10:50:16 +0200 [thread overview]
Message-ID: <20180919085016.164552924@infradead.org> (raw)
Thomas' CPA patches made me look at the tlb invalidate crud around there. These
patches are the result of cleaning some of that up a bit. They are based on top
of Thomas' patches.
Dave, can you have a wee look at the Atom errata thing; this does grow the
amount of code between the page-table update and the TLB flush a bit, but all
that PTI crud we did a while back already made it a non-trivial amount of code.
