Hi Linus,
Please pull these arm64 fixes for -rc1. The major fix here is for a
filesystem corruption issue reported on Apple M1 as a result of buggy
management of the floating point register state introduced in 6.8. I
initially reverted one of the offending patches, but in the end Ard
cooked a proper fix so there's a revert+reapply in the series.
Aside from that, we've got some CPU errata workarounds and the rest is
summarised in the tag.
Cheers,
Will
