Hi Dmitry,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on 62918e6fd7b5751c1285c7f8c6cbd27eb6600c02]
url:
https://github.com/0day-ci/linux/commits/Dmitry-Safonov/Add-generic-vdso_base-tracking/20201124-083732
base:62918e6fd7b5751c1285c7f8c6cbd27eb6600c0
Generic way to track the landing vma area.
As a bonus, after unmapping vdso, kernel won't try to land on its
previous position (due to UNMAPPED_VDSO_BASE check instead of
context.vdso ?= 0 check).
