Subject[PATCH v3 00/13] arm64 kpti hardening and variant 2 workarounds
Date
Hi all,

This is version three of the patches previously posted here:

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-January/551838.html
v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-January/552085.html

Changes since v2:

* Fix typo in comment
* Include Falkor hardening from Shanker
* Add ThunderX2 MIDRs (subsequent patches under review)
* Avoid applying hardening from preemtible context
* Fix stack offsets in hyp SMC call

Cheers,

Will
