- 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

instructions, so extend the decode mask for B.cond to cover BC.cond
- Flush the walk cache when unsharing PMD tables. Recent changes to
