Hello,
These patches are related to a recently queued series [1] that fixes the
same bugs in normal code. That series finishes with a patch that would
have exposed the BPF bugs, but luckily it won't get merged until v6.18.
I don't know enough about BPF to verify that it emits the correct code
now, so any pointers are welcome.

Both patches look good so:

Since this only touches riscv and I have a bunch of fixes pending, I
propose to take those patches through the riscv tree, I'll just wait for
Björn to confirm it is correct.
@Radim: This is the third similar bug, did you check all assembly code
(and bpf) to make sure we don't have anymore left or should I?
Thanks,
Alex
