Subject: [PATCH v2 0/3] io-pgtable ARM short descriptor format
Date: Thu, 17 Dec 2015 20:50:56 +0000 [thread overview]
Message-ID: <cover.1450383740.git.robin.murphy@arm.com> (raw)
Hi all,
A few small changes in io-pgtable-arm-v7s.c to address Yong's comments:
- Add a comment explaining "cont".
- Keep kmemleak quiet.
- Make the loop in arm_v7s_iova_to_phys, and correspondingly the
level test in the ARM_V7S_PTE_IS_TABLE macro, more sane.
I've dropped the fixes which Will has queued already, even if it does
mean my own semicolons will never get to see the light of day :(
I'm posting patches 2 and 3 as a series with this as they're inspired
by the sync issue raised on v1 and touch the code in patch 1, but those
two are really more of an RFC idea than intended 4.5 material.
Robin.
