#     sparc64: Fix regression in pmdp_invalidate().
#     
#     pmdp_invalidate() was changed to update the pmd atomically
#     (to not lose dirty/access bits) and return the original pmd
#     value.
#     
#     However, in doing so, we lost a lot of the essential work that
#     set_pmd_at() does, namely to update hugepage mapping counts and
#     queuing up the batched TLB flush entry.
#     
#     Thus we were not flushing entries out of the TLB when making
#     such PMD changes.
#     
#     Fix this by abstracting the accounting work of set_pmd_at() out into a
#     separate function, and call it from pmdp_establish().
#     
#     Fixes: a8e654f01cb7 ("sparc64: update pmdp_invalidate() to return old pmd value")
