Potential dangerous invalid memory might be accessed if invalid mac value
reflected from the forward port field in rxd4 caused by possible potential
hardware defects. So added a simple sanity checker to avoid the kind of
situation happening.

Presently, the phy pipe clock's name is assumed to be either
usb3_phy_pipe_clk_src or pcie_XX_pipe_clk_src (where XX is the
phy lane's number). However, this will not work if an SoC has
more than one instance of the phy. Hence, instead of assuming
the name of the clock, fetch it from the DT.

The core init is the similar to the existing SoC, however the

Hi all,
Changes since 20170719:
The kbuild tree still produces a large number of build warnings so I
reverted a commit from it.
The drm-misc tree gained conflict a conflict against the drm-intel tree.
The userns tree gained a build failure so I used the version from
next-20170719.

The thing is, the "actual RAM" case

So ghes_edac *is* a poor man's driver in the sense that it doesn't do
anything fancy but repeat like a parro
This patch adds Broadcom FlexRM low-level reset for
VFIO platform.
It will do the following:
1. Disable/Deactivate each FlexRM ring
2. Flush each FlexRM ring
The cleanup sequence for FlexRM rings is adapted from
Broadcom FlexRM mailbox driver.

Not allowing No-IOMMU mode for devices already having
iommu_ops on their bus is very conservative.
We now have IOMMU (such as ARM SMMU) which can bypass
transcations when IOMMU is not configured for a given
device. In addition, it is not necessary to have all
devices on bus to be upstream to an IO
This patchset primarily adds Broadcom FlexRM reset module for
VFIO platform driver. We also have minor improvments in IOMMU
and VFIO driver to allow VFIO no-IOMMU mode access to FlexRM.
The patches are based on Linux-4.13-rc1 and can also be
found at flexrm-vfio-v2 branch of

Yeah, that would be a nasty, back-stabbing SNAFU.

Hi all,
After merging the char-misc tree, yesterday's linux-next build (i386

Hi everyone,
This is v2 of my MMC controller support series.
Changes since v1:
- Fix patches already applied have been dropped
- V2 now exports sunxi-ng mmc timing mode API functions
(in case mmc driver is built as a module)
- Added stub functions for the timing mode API functions,
The A83T has 3 MMC controllers. The third one is a bit special, as it
supports a wider 8-bit bus, and a "new timing mode".
