Hi Linus,
Please pull this tiny arm64 fix for -rc7, which tells recent versions of
clang where to find the assembler for building the compat vDSO.
Cheers,
Will

Hi Linus,
Please pull this single arm64 fix for -rc7. It's a revert of 747a70e60b72
("arm64: Fix copy-on-write referencing in HugeTLB"), not because that
patch was wrong, but because it was broken by aa57157be69f ("arm64: Ensure
VM_WRITE|VM_SHARED ptes are clean by default") which we merged in -rc6.
We spotted the issue in Android (AOSP), where one of the JIT threads gets
stuck on a write fault during boot because the faulting pte is marked as
PTE_DIRTY | PTE_WRITE | PTE_RDONLY and the fault handler decides that
there's nothing to do thanks to pte_same() masking out PTE_RDONLY.
Thanks to John Stultz for reporting this and testing this so quickly, and
to Steve Capper for confirming that the HugeTLB tests continue to pass.
Cheers,
Will
