Miller # Date: Thu Mar 15 14:18:00 2018 -0700 # # 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") # Signed-off-by: David S.
