  arm64: tlb: Flush walk cache when unsharing PMD tables (2026-05-22 11:13:51 +0100)

----------------------------------------------------------------
arm64 fixes:

 - 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
