df59fa7f4b spi: orion: support armada extended baud rates
The Armada SoC family implementation of this SPI hardware module has
extended the configuration register to allow for a wider range of SPI
clock rates. Specifically the Serial Baud Rate Pre-selection bits in the
SPI Interface Configuration Register now also use bits 6 and 7 as well.

Modify the baud rate calculation to handle these differences for the
Armada case. Potentially a baud rate can be setup using a number of
different pre-scalar and scalar combinations. This code tries all
possible pre-scalar divisors (8 in total) to try and find the most
accurate set.

This change introduces (and documents) a new device tree compatible
device name "armada-370-spi" to support this.

2b260085e4 PCI/MSI: Use __get_cached_msi_msg() instead of get_cached_msi_msg()
Both callers of get_cached_msi_msg() start with a struct irq_data pointer,
look up the corresponding IRQ number, and pass it to get_cached_msi_msg(),
which then uses irq_get_irq_data() to look up the struct irq_data again to
call __get_cached_msi_msg().

Since we already have the struct irq_data, call __get_cached_msi_msg()
directly and skip the lookup work done by get_cached_msi_msg().

No functional change.

468ff15a3a PCI/MSI: Add "msi_bus" sysfs MSI/MSI-X control for endpoints
The "msi_bus" sysfs file for bridges sets a bus flag to allow or disallow
future driver requests for MSI or MSI-X.  Previously, the sysfs file
existed for endpoints but did nothing.

Add "msi_bus" support for endpoints, so an administrator can prevent the
use of MSI and MSI-X for individual devices.

Note that as for bridges, these changes only affect future driver requests
for MSI or MSI-X, so drivers may need to be reloaded.

Add documentation for the "msi_bus" sysfs file.

Proper CHECKSUM_COMPLETE support needs to adjust skb->csum
when we remove one header. Its done using skb_gro_postpull_rcsum()

In the case of IPv4, we know that the adjustment is not really needed,

4598a0a6d2 perf symbols: Improve DSO long names lookup speed with rbtree
With workload that spawns and destroys many threads and processes, it
was found that perf-mem could took a long time to post-process the perf
data after the target workload had completed its operation.

The performance bottleneck was found to be the lookup and insertion of
the new DSO structures (thousands of them in this case).

In a dual-socket Ivy-Bridge E7-4890 v2 machine (30-core, 60-thread), the
perf profile below shows what perf was doing after the profiled AIM7
shared workload completed:

-     83.94%  perf  libc-2.11.3.so     [.] __strcmp_sse42
   - __strcmp_sse42
      - 99.82% map__new
           machine__process_mmap_event
           perf_session_deliver_event
           perf_session__process_event
           __perf_session__process_events
           cmd_record
           cmd_mem
           run_builtin
           main
           __libc_start_main
-     13.17%  perf  perf               [.] __dsos__findnew
     __dsos__findnew
     map__new
     machine__process_mmap_event
     perf_session_deliver_event
     perf_session__process_event
     __perf_session__process_events
     cmd_record
     cmd_mem
     run_builtin
     main
     __libc_start_main

So about 97% of CPU times were spent in the map__new() function trying
to insert new DSO entry into the DSO linked list. The whole
post-processing step took about 9 minutes.

The DSO structures are currently searched linearly. So the total
processing time will be proportional to n^2.

To overcome this performance problem, the DSO code is modified to also
put the DSO structures in a RB tree sorted by its long name in
additional to being in a simple linked list. With this change, the
processing time will become proportional to n*log(n) which will be much
quicker for large n. However, the short name will still be searched
using the old linear searching method.  With that patch in place, the
same perf-mem post-processing step took less than 30 seconds to
complete.

DMIC route in the rt5640 codec driver anymore after commit

Since DMIC interface must be enabled explicitly either by passing platform

patch adds a DMI quirk flag that is used to conditionally enable DMIC
interface during sound card init time.

cd69dc8868 ASoC: rt5640: Add function for enabling DMIC from ACPI probed machine
There is no code enabling DMIC clock in systems that don't provide platform
data for rt5640 after commit 71d97a7943 ("ASoC: rt5640: Use the platform
data for DMIC settings").

I think it's worth to keep this static DMIC clock and alternative data pin
setting during probe time. For making possible to use DMIC from ACPI probed
machine (prior ACPI 5.1 with _DSD) this patch moves DMIC configuration to
new exported rt5640_dmic_enable() that machine drivers can call.

Please note, this patch moves DMIC configuration from i2c probe to codec
probe in case platform data for rt5640 is set.

f114ce605d ASoC: davinvi-mcasp: Proper suspend/resume support while audio is active
If the board is sent to suspend (deep sleep) the McASP context will be lost.
In case when suspend happens during active audio we need to save and restore
more registers, which was configured during hw_param times as well.
We need to add more config registers, AFIFO control registers and we also
need to save and restore the serializer configuration as well.
Since the number of serializers depends on the SoC we need to allocate the
memory for it based on the num_serializer for the given McASP instance.

With this patch the ongoing stream will resume after resuming from deep
sleep.

e66c98c7a0 of: Fix NULL dereference in selftest removal code
The selftest code removes its testcase data from the live tree when
exiting, but if the testcases data tree contains an empty child of the
root, then it causes an oops due to a NULL dereference. The reason is
that the code tries to directly dereference the child pointer without
checking first if a child is actually there.

The solution is to pass the parent node into detach_node_and_children()
instead of trying to pass the child. This required removing the code
that attempts to remove all of the sibling nodes in
detach_node_and_children(), which was never sensible in the first place.

At the same time add a check to make sure the bounds of the nodes list
are not exceeded by the testdata tree. If they are then abort.

Keystone supports dma-coherent on USB master and also needs
dma-ranges to specify the hardware alias memory range in which DMA
can be operational.
Such configuration applied for USB0 devices, but It's missed for
USB1 device which is present only in K2E SoC - hence apply it.

19aeb5a65f GFS2: Make rename not save dirent location
This patch fixes a regression in the patch "GFS2: Remember directory
insert point", commit 2b47dad866.
The problem had to do with the rename function: The function found
space for the new dirent, and remembered that location. But then the
old dirent was removed, which often moved the eligible location for
the renamed dirent. Putting the new dirent at the saved location
caused file system corruption.

This patch adds a new "save_loc" variable to struct gfs2_diradd.
If 1, the dirent location is saved. If 0, the dirent location is not
saved and the buffer_head is released as per previous behavior.
