Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Catalin Marinas:

 - Handle probe on hinted conditional branch instructions.

   BC.cond instructions can be simulated in the same way as B.cond
   instructions, so extend the decode mask for B.cond to cover BC.cond

 - Flush the walk cache when unsharing PMD tables. Recent changes to
   huge_pmd_unshare() introduced mmu_gather::unshared_tables but the
   arm64 code was still treating the TLB flushing as only targeting leaf
   entries (TLBI VALE1IS).

   Fix it by using non-leaf-only instructions (TLBI VAE1IS) when
   tlb->unshared_tables is set
