Direct store is implemented by using write combining (WC) for writing

This reverts commit fe5b85c656bc. The SDMA engine needs the descriptors to
be contiguous in memory. As the dma pool API is only able to provide a
single descriptor per alloc invocation there is no guarantee that multiple
descriptors satisfy this requirement. Also the code in que
From: Lucas Stach
The dmaengine documentation states that device_terminate_all may be
asynchronous and need not wait for the active transfers to stop.
This allows us to move most of the functionality currently implemented
in the sdma channel termination function to run in a worker, outside
of an
This patch set to correct dma pool used in the commit fe5b85c656bc

because all bds should be contiguous in memory in multi bds case

The function coh901318_alloc_chan_resources() calls spin_lock_irqsave()
before calling coh901318_config().
But coh901318_config() calls spin_lock_irqsave() again in its
definition, which may cause a double-lock bug.
Because coh901318_config() is only called by
coh901318_alloc_chan_resources(), th

Hi all,
Changes since 20181105:
New trees: risc-v-pjw, sifive, i3c-fixes, i3c
The drm-msm tree gained a conflict against the drm-misc tree.
The tip tree gained a build failure for which I applied a fix patch.
Non-merge commits (relative to Linus' tree): 825
1082 files changed,
Right, should replace it with SK_HYNIX.
I'll prepare v2 patch for that.

Now that you added PCI_VENDOR_ID_SK_HYNIX to pci_ids.h, you
could use PCI_VENDOR_ID_SK_HYNIX above instead of 0x1c5c.

It leads to the power consumption raises to 2.2W during s2idle, while
it consumes less than 1W during long idle if put SK hynix nvme to D3
and then enter s2idle.

To leverage its APST feat
Call nvme_dev_disable() function leads to the power consumption goes
up to 2.2 Watt during suspend-to-idle, and from SK hynix FE, they
suggest us to use its own APST feature to do the power management during
s2idle.
After D3 is diabled and nvme_dev_disable() is not called while
suspending, the powe
