The patch titled
rework-ptep_set_access_flags-and-fix-sun4c-fix-fix-fix
has been removed from the -mm tree. Its filename was
rework-ptep_set_access_flags-and-fix-sun4c-fix-fix-fix.patch
This patch was dropped because it was folded into rework-ptep_set_access_flags-and-fix-sun4c.patch
------------------------------------------------------
Subject: rework-ptep_set_access_flags-and-fix-sun4c-fix-fix-fix
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
Some changes done a while ago to avoid pounding on ptep_set_access_flags
and update_mmu_cache in some race situations break sun4c which requires
update_mmu_cache() to always be called on minor faults.
This patch reworks ptep_set_access_flags() semantics, implementations
and callers so that it's now responsible for returning whether an update
is necessary or not (basically whether the PTE actually changed). This
allow fixing the sparc implementation to always return 1 on sun4c.
Hope I got ia64 right this time !
