14f0413ce3 ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
Currently GPIO4 is hardcoded to output the pll-lock signal.
Unfortunately this is after the pll-out GPIO is configured which
is selectable in the device tree. Therefore it is not possible to
use GPIO4 for pll-out. Therefore this patch removes the
configuration of GPIO4.

12522eeac8 Revert "dmaengine: Add a warning for drivers not using the generic slave caps retrieval"
This reverts commit ecc19d1786.

It added a new warning to try to encourage driver writers to set the
device capabities properly, but drivers haven't been updated and in the
meantime it just generaters a scary message that users cannot actually
do anything about.

Warnings like these are appropriate if you actually expect to fix the
code that causes them.  They are not appropriate for releases.

ac2111753c blk-mq: initialize 'struct request' and associated data to zero
Jan Engelhardt reports a strange oops with an invalid ->sense_buffer
pointer in scsi_init_cmd_errh() with the blk-mq code.

The sense_buffer pointer should have been initialized by the call to
scsi_init_request() from blk_mq_init_rq_map(), but there seems to be
some non-repeatable memory corruptor.

This patch makes sure we initialize the whole struct request allocation
(and the associated 'struct scsi_cmnd' for the SCSI case) to zero, by
using __GFP_ZERO in the allocation.  The old code initialized a couple
of individual fields, leaving the rest undefined (although many of them
are then initialized in later phases, like blk_mq_rq_ctx_init() etc.

It's not entirely clear why this matters, but it's the rigth thing to do
regardless, and with 4.0 imminent this is the defensive "let's just make
sure everything is initialized properly" patch.

user_64bit_mode(regs) basically checks regs->cs to point to a

Now regs->cs is always correct: in syscalls, in interrupts, in

b815fc12d4 iscsi target: fix oops when adding reject pdu
This fixes a oops due to a double list add when adding a reject PDU for
iscsit_allocate_iovecs allocation failures. The cmd has already been
added to the conn_cmd_list in iscsit_setup_scsi_cmd, so this has us call
iscsit_reject_cmd.

Note that for ERL0 the reject PDU is not actually sent, so this patch
is not completely tested. Just verified we do not oops. The problem is the
add reject functions return -1 which is returned all the way up to
iscsi_target_rx_thread which for ERL0 will drop the connection.

704f32d48a spi: bcm2835: enabling polling mode for transfers shorter than 30us
In cases of short transfer times the CPU is spending lots of time
in the interrupt handler and scheduler to reschedule the worker thread.

Measurements show that we have times where it takes 29.32us to between
the last clock change and the time that the worker-thread is running again
returning from wait_for_completion_timeout().

During this time the interrupt-handler is running calling complete()
and then also the scheduler is rescheduling the worker thread.

This time can vary depending on how much of the code is still in
CPU-caches, when there is a burst of spi transfers the subsequent delays
are in the order of 25us, so the value of 30us seems reasonable.

With polling the whole transfer of 4 bytes at 10MHz finishes after 6.16us
(CS down to up) with the real transfer (clock running) taking 3.56us.
So the efficiency has much improved and is also freeing CPU cycles,
reducing interrupts and context switches.

Because of the above 30us seems to be a reasonable limit for polling.

a30a555d74 spi: bcm2835: transform native-cs to gpio-cs on first spi_setup
Transforms the bcm-2835 native SPI-chip select to their gpio-cs equivalent.

This allows for some support of some optimizations that are not
possible due to HW-gliches on the CS line - especially filling
the FIFO before enabling SPI interrupts (by writing to CS register)
while the transfer is already in progress (See commit: e3a2be3030)

This patch also works arround some issues in bcm2835-pinctrl which does not
set the value when setting the GPIO as output - it just sets up output and
(typically) leaves the GPIO as low.  When a fix for this is merged then this
gpio_set_value can get removed from bcm2835_spi_setup.

23296099e7 regulator: output current-limit for all regulators in summary
Voltage regulators can have (unregulated) current limits too, so we should
probably output both voltage and current for all regulators.

Holding the rdev->mutex actually conflicts with _regulator_get_current_limit
but also is not really necessary, as the global regulator_list_mutex already
protects us from the regulator vanishing while we go through the list.

On the rk3288-firefly the summary now looks like:

 regulator                      use open bypass voltage current     min     max
-------------------------------------------------------------------------------

7c225ec90c regulator: add a summary tree in debugfs
On modern systems the regulator hierarchy can get quite long and nested
with regulators supplying other regulators. In some cases when debugging
it might be nice to get a tree of these regulators, their consumers
and the regulation constraints in one go.

To achieve this add a regulator_summary sysfs node, similar to
clk_summary in the common clock framework, that walks the regulator
list and creates a tree out of the regulators, their consumers and
core per-regulator settings.

On a rk3288-firefly the regulator_summary would for example look
something like:

 regulator                      use open bypass   value     min     max

ca3f087472 KVM: use slowpath for cross page cached accesses
kvm_write_guest_cached() does not mark all written pages as dirty and
code comments in kvm_gfn_to_hva_cache_init() talk about NULL memslot
with cross page accesses.  Fix all the easy way.

The check is '<= 1' to have the same result for 'len = 0' cache anywhere
in the page.  (nr_pages_needed is 0 on page boundary.)

Fixes: 8f964525a1 ("KVM: Allow cross page reads and writes from cached translations.")

69f0fb2a59 mmc: sdhci-st: Update ST SDHCI binding documentation.
This patch updates the binding information to reflect the
extra dt options which are now supported by the sdhci-st.c
driver which enable support for stih407 family silicon.

STiH410 SoC and later support UHS modes for eMMC, so the
driver now makes use of these common bindings. Examples
are provided for both eMMC (which has additional bindings)
and also sd slot for STiH407.

4e187d3154 mmc: sdhci-st: Update the quirks for this controller.
Some additional quirks need to be enabled now we support UHS
modes. This avoids some spurious warnings like

"Got data interrupt 0x00000002 even though no data operation was in progress"

Testing on stih410-b2120 board achieves the following speeds
with HS200 eMMC card.

max-frequency = 200Mhz
/dev/mmcblk0p1:
 Timing buffered disk reads: 270 MB in  3.02 seconds =  89.54 MB/sec

max-frequency = 100Mhz
root@debian-armhf:~# hdparm -t /dev/mmcblk0p1
/dev/mmcblk0p1:
 Timing buffered disk reads: 210 MB in  3.00 seconds =  70.00 MB/sec

max-frequency = 50Mhz
root@debian-armhf:~# hdparm -t /dev/mmcblk0p1
/dev/mmcblk0p1:
 Timing buffered disk reads: 118 MB in  3.00 seconds =  39.28 MB/sec

This is better than the 3.10 kernel which achieves 77.59 MB/sec
at 200Mhz clock (same board/soc/eMMC).
