If you're going to use the B (1T segment) bit instead of the bolted bit,
at least define a proper constant in line with the existing naming of
the hash table constants in mmu-hash64.h. I would suggest doing the same
with the VRMA_MASK/VALUE thing and calling it HPTE_V_VRMA_MASK or
something similar.

In addition, I would recommend following Michael's advice and using
using the bulk remove Hcall whenever possible.
