Palmer Dabbelt 9b7fef255c Merge patch series "riscv: asid: switch to alternative way to fix stale TLB entries" 
Sergey Matyukevich <geomatsi@gmail.com> says:

Some time ago two different patches have been posted to fix stale TLB
entries that caused applications crashes.

The patch [0] suggested 'aggregating' mm_cpumask, i.e. current cpu is not
cleared for the switched-out task in switch_mm function. For additional
explanations see the commit message by Guo Ren. The same approach is
used by arc architecture, so another good comment is for switch_mm
in arch/arc/include/asm/mmu_context.h.

The patch [1] attempted to reduce the number of TLB flushes by deferring
(and possibly avoiding) them for CPUs not running the task.

Patch [1] has been merged. However we already have two bug reports from
different vendors. So apparently something is missing in the approach
suggested in [1]. In both cases the patch [0] fixed the issue.

This patch series reverts [1] and replaces it by [0].
