This is a backport of the series that recently went into 5.8. Note that the first patch is more a complete rewriting than a backport, as the vdso implementation in 5.4 doesn't have much in common with mainline. This affects the 32bit arch code in a benign way.
It has seen very little testing, as I don't have the HW that triggers this issue. I have run it in VMs by faking the CPU MIDR, and nothing caught fire. Famous last words.
These are also needed in 5.7.y, right? If so, I need that series before I can take this one as we don't want people moving to a newer kernel and suffer regressions :(
The original mainline changes:
4b661d6133c5 arm64: arch_timer: Disable the compat vdso for cores affected by ARM64_WORKAROUND_1418040 c1fbec4ac0d7 arm64: arch_timer: Allow an workaround descriptor to disable compat vdso 97884ca8c292 arm64: Introduce a way to disable the 32bit vdso
do apply cleanly to stable-5.7. Do you want me to resend them separately, or will you pick the patches directly from mainline?
Thanks,
M.
