Richard Henderson 3ab6e68cd0 accel/tcg: Add tlb_flush_page_bits_by_mmuidx*
On ARM, the Top Byte Ignore feature means that only 56 bits of
the address are significant in the virtual address.  We are
required to give the entire 64-bit address to FAR_ELx on fault,
which means that we do not "clean" the top byte early in TCG.

This new interface allows us to flush all 256 possible aliases
for a given page, currently missed by tlb_flush_page*.
