Subject: [GIT PULL] iommu/arm-smmu: updates for 3.15
Date: Fri, 28 Feb 2014 11:05:25 +0000 [thread overview]
Message-ID: <20140228110525.GA674@mudshark.cambridge.arm.com> (raw)
Hi Joerg,
Please can you pull the following arm-smmu changes for 3.15?
The main changes are for accessing the buggy Calxeda SMMU, which is wired
as secure despite being non-secure. Unfortunately, the apparent demise
of Calxeda means that Andreas is no longer working on this, so I had to
extract what I could from a larger patchset (which wasn't yet ready for
merging in its entirety).
On my side, there's some cosmetic changes after Joerg fixed some locks
to use spin_lock_irq{save,restore} and also an optimisation to restrict
the scope of our barrier when publishing page tables (now that ARM64 can
accept the option).
Cheers,
Will
