Subject[PATCH v4 0/2] context tracker support for arm64
Date
Implement and enable context tracking for arm64 (which is
a prerequisite for FULL_NOHZ support). This patchset
builds upon earlier work by Kevin Hilman and is based on
Will Deacon's tree.

Changes v3 to v4:

* Rename parameter of ct_user_exit from save to restore
* Rebased patch to Will Deacon's tree (branch remotes/origin/aarch64
of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git)

Changes v2 to v3:

* Save/restore necessary registers in ct_user_enter and ct_user_exit
* Annotate "error paths" out of el0_sync with ct_user_exit

Changes v1 to v2:

* Save far_el1 in x26 temporarily

Larry Bassel (2):
arm64: adjust el0_sync so that a function can be called
arm64: enable context tracking
