Subject: [MODERATED] Updated L1TF native OS patch
Date: Tue, 1 May 2018 16:42:47 -0700	[thread overview]
Message-ID: <20180501234247.GA41910@tassilo.jf.intel.com> (raw)

[no threaded cover letter because I haven't figured out how
to do that with the speck tools]

Here's a v2 of the L1TF native OS patch kit. I reworked
it based on Linus suggestions. Instead of explicit masks it now
uses inversion for swap entries and the PFN part of PROT_NONE
entries. The swap entry patch is Linus' with only minor comment
changes and some testing.

It drops supports for mitigation high MMIO. After some discussion
we decided that is too unlikely to happen, and with inversion
it is somewhat painful.
