Pull PCI fixes from Bjorn Helgaas:
"Since v4.5, we've WARNed during resume if a PCI device, including a
Thunderbolt device, was added while we were suspended. A change we
merged for v4.6-rc1 turned that warning into a system hang. These

Current checking for PLL 32KHz mode fails in driver code when
bypassing the PLL. This is due to an incorrect check of PLL
source type when 32KHz clock is provided. Removal of this check
resolves the issue.

Currently PC counter is always synchronised to DAI which means that

When the codec is DAI clk slave, and the SRM feature of the PLL
is being used, the enabling of the DAI should occur only after
the PLL has locked to the incoming WCLK. This update adds checking
to the the DAI widget event, so it waits for SRM to lock. There is
also a timeout if that lock doesn't occur within a given time.

improving the sja1000 driver. Amitoj Kaur Chawla's patch converts the
mcp251x driver to alloc_workqueue(). A patch by Oliver Hartkopp fixes
the handling of CAN config options. Andreas Gröger improves the error
handling in the janz-ican3 driver. The patch by Maximilian Schneider
for the gs_usb improves probing of the USB driver. Finally there are 6

Current rsnd_dmapp_get_id() returns 0xFF as error code if system used
strange connection. It will be used as PDMACHCRn.SRS, but 0xFF is
prohibited number.
In order not to use prohibited number, this patch indicates error message
and returns 0x00 (same as SSI00) in error case.

Although the ES8328 does support different rates for capture and
playback, only very limited combinations are supported (8kHz and 48kHz
or 8.0182kHz and 44.1kHz) with most rates required to be symmetric.
Instead of adding a lot of complexity for little gain, let's enforce
symmetric rates.

Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.
This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.
With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

ata_sff_qc_issue() can't handle DMA commands and thus we have to avoid it for
them. Do call ata_bmdma_qc_issue() instead for this case. Note that the former

Calling dmaengine_prep_slave_sg() for non-dma ATA commands is
unnecessary at best and could be harmful if the dma driver reacts
badly to this. It also causes this driver to print a bogus error
message in these cases.
This patch changes sata_dwc_qc_issue() to only do the dma setup
for dma commands and also reports an error to libata if if fails.

The burst size as defined by DMAengine API is in items of address width. Derive
burst size from AHB_DMA_BRST_DFLT (64 bytes) by dividing it to
DMA_SLAVE_BUSWIDTH_4_BYTES (4 bytes) that gives us 16 items.

The original code states:
Make sure a LLI block is not created that will span 8K max FIS
boundary. If the block spans such a FIS boundary, there is a chance
that a DMA burst will cross that boundary -- this results in an error
in the host controller.
Since we have switched to generic DMAengine API we satisfy above by setting
dma_boundary value to 0x1fff.

This patch fixes Machine Check "Data Write PLB Error" which happens
when libata-sff's ata_sff_dev_select is trying to write into the
device_addr in order to select a drive. However, SATA has no master
or slave devices like the old ATA Bus, therefore selecting a
different drive is kind of pointless.

This is an initial implementation of a netdev driver for GTP datapath
(GTP-U) v0 and v1, according to the GSM TS 09.60 and 3GPP TS 29.060
standards. This tunneling protocol is used to prevent subscribers from
accessing mobile carrier core network infrastructure.
This implementation requires a GGSN userspace daemon that implements the
signaling protocol (GTP-C), such as OpenGGSN [1]. This userspace daemon
updates the PDP context database that represents active subscriber
sessions through a genetlink interface.
For more context on this tunneling protocol, you can check the slides
that were presented during the NetDev 1.1 [2].
Only IPv4 is supported at this time.

The kbuild test robot reported this objtool warning [1]:
arch/x86/kvm/emulate.o: warning: objtool: fastop()+0x69: call without frame pointer save/setup
The issue seems to be caused by CONFIG_PROFILE_ALL_BRANCHES. With that
option, for some reason gcc decides not to create a stack frame in
fastop() before doing the inline asm call, which can result in a bad
stack trace.
Force a stack frame to be created if CONFIG_FRAME_POINTER is enabled by
listing the stack pointer as an output operand for the inline asm
statement.
This change has no effect for !CONFIG_PROFILE_ALL_BRANCHES.
