From: Joerg Roedel <jroe...@suse.de>
Changes V3->V4:
* Rebased to v3.18-rc2
* Updated patch description and some comments
Changes V2->V3:
* Rebased to v3.17-rc4
* Fixed compile error because pmdp_get_and_clear_notify was
missing
Changes V1->V2:
* Rebase to v3.16-rc7
* Added call of ->invalidate_range to
__mmu_notifier_invalidate_end() so that the subsystem
doesn't need to register an ->invalidate_end() call-back,
subsystems will likely either register
invalidate_range_start/end or invalidate_range, so that
should be fine.
* Re-orded declarations a bit to reflect that
invalidate_range is not only called between
invalidate_range_start/end
* Updated documentation to cover the case where
invalidate_range is called outside of
invalidate_range_start/end to flush page-table pages out
of the TLB
Hi,
here is v4 of my patch-set which extends the mmu-notifiers
to allow managing CPU external TLBs. A more in-depth
description on the How and Why of this patch-set can be
found in the description of patch 1/3.
Any comments and review appreciated!
Thanks,
Joerg
