b4423bb834 ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4
Add defconfig for Linux on Vybrid (vf610) on the secondary Cortex-
M4 CPU. The use of a XIP image has been tested which needs to be
loaded (e.g. using the custom m4boot loader) to the end of the
available RAM at address 0x8f000000. The Cortex-M4 has a code-alias
which makes sure that the instructions get fetched through the code
bus (alias starts at 0x00800000 => 0x80800000 in system address).
Hence, to get optimal performance, use 0x0f000000 as XIP_PHYS_ADDR.
This address is additionally shifted by the length of the minimal
loader which is inserted by m4boot. Currently, this offset is 0x80.

The standard DRAM base address is configured to 0x8C000000, which
gives the Cortex-M4 48MiB of RAM.

8064887e02 ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC
This patch allows to build the Kernel for Vybrid (VF6xx) SoC
when ARMv7-M CPU is selected. The resulting image runs on the
secondary Cortex-M4 core. This core has equally access to all
peripherals as the main Cortex-A5 core. However, there is no
resource control mechanism, hence when both cores are used
simultaneously, orthogonal device tree's are required.

The boot CPU is dependent on the SoC variant. The available
boards use mostly variants where the Cortex-A5 is the primary
and hence the boot CPU. Booting the secondary Cortex-M4 CPU
needs SoC specific registers written. There is no in kernel
support for this right now, a external userspace utility
called "m4boot" can be used to boot the kernel:

m4boot xipImage initramfs.cpio.lzo vf610m4-colibri.dtb

9c77bc438f ARM: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms
This introduces a new top level config symbol ARM_SINGLE_ARMV7M
for non-MMU, ARMv7-M platforms. It also support multiple ARMv7-M
platforms in one kernel image since the cores share the same
basic memory layout and interrupt controller. However, this works
only if the combined platforms also have a similar (main) memory
layout.

c07678bb01 IB/cma: Fix broken AF_IB UD support
Support for using UD and AF_IB is currently broken.  The
IB_CM_SIDR_REQ_RECEIVED message is not handled properly in
cma_save_net_info() and we end up falling into code that will try and
process the request as ipv4/ipv6, which will end up failing.

The resolution is to add a check for the SIDR_REQ and call
cma_save_ib_info() with a NULL path record.  Change cma_save_ib_info()
to copy the src sib info from the listen_id when the path record is NULL.

4afe260bab CIFS: Fix race condition on RFC1002_NEGATIVE_SESSION_RESPONSE
This patch fixes a race condition that occurs when connecting
to a NT 3.51 host without specifying a NetBIOS name.
In that case a RFC1002_NEGATIVE_SESSION_RESPONSE is received
and the SMB negotiation is reattempted, but under some conditions
it leads SendReceive() to hang forever while waiting for srv_mutex.
This, in turn, sets the calling process to an uninterruptible sleep
state and makes it unkillable.

The solution is to unlock the srv_mutex acquired in the demux
thread *before* going to sleep (after the reconnect error) and
before reattempting the connection.

Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Use this to simplify the driver. Furthermore this is one caller less
that stops us making the flags argument to gpiod_get*() mandatory.

1137e58069 ASoC: sta32x: use devm_gpiod_get_optional for optional reset gpio
Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Also there is a variant to find optional gpios that returns NULL if
there is no gpio instead of -ENOENT.

Make use of both features to simplify the driver.

This changes behaviour if gpiod_get returns -ENOSYS which is the case if
CONFIG_GPIOLIB is not enabled. This is a good change because without
GPIOLIB there is no way to determine if the reset gpio is specified in
the device tree. And if it is it must be handled, so erroring out is the
right thing to do.

Furthermore this is one caller less that stops us making the flags
argument to gpiod_get*() mandatory.

0574eab363 ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency, again
I tried to fix this before and submitted a working patch, but after
some discussion we came up with what seemed to be a nicer solution,
resulting in commit 3d4cf65e2d ("ASoC: omap: fix up
SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency"). Unfortunately, that
version was incomplete, and we still get this build error:

drivers/clk/clk-palmas.c:46:16: error: field 'hw' has incomplete type
drivers/clk/clk-palmas.c: In function 'to_palmas_clks_info':
drivers/clk/clk-palmas.c:54:74: warning: initialization from incompatible pointer type [-Winc

This happens only in randconfig builds that turn on MFD_PALMAS
on a platform other than OMAP2+ when COMPILE_TEST is set
but COMMON_CLK is not.

The new approach is only 'select COMMON_CLK_PALMAS' if we know
that we are on an OMAP5 platform and MFD_PALMAS is already set.
This patch has survived thousands of randconfig builds and I
don't see a remaining hole in the logic.

When server is Windows, cifs client has same problem.
When Server is Windows
, This patch fixes bug in different filetype,

Because QUERY_PATH_INFO response by Windows does not include inode number(Index Number) .

153c35b6cc Btrfs: fix regression in raid level conversion
Commit 2f0810880f changed
btrfs_set_block_group_ro to avoid trying to allocate new chunks with the
new raid profile during conversion.  This fixed failures when there was
no space on the drive to allocate a new chunk, but the metadata
reserves were sufficient to continue the conversion.

But this ended up causing a regression when the drive had plenty of
space to allocate new chunks, mostly because reduce_alloc_profile isn't
using the new raid profile.

Fixing btrfs_reduce_alloc_profile is a bigger patch.  For now, do a
partial revert of 2f0810880, and don't error out if we hit ENOSPC.

521a04d06a Revert "libceph: clear r_req_lru_item in __unregister_linger_request()"
This reverts commit ba9d114ec5.

.. which introduced a regression that prevented all lingering requests
requeued in kick_requests() from ever being sent to the OSDs, resulting
in a lot of missed notifies.  In retrospect it's pretty obvious that
r_req_lru_item item in the case of lingering requests can be used not
only for notarget, but also for unsent linkage due to how tightly
actual map and enqueue operations are coupled in __map_request().

The assertion that was being silenced is taken care of in the previous
("libceph: request a new osdmap if lingering request maps to no osd")
commit: by always kicking homeless lingering requests we ensure that
none of them ends up on the notarget list outside of the critical
section guarded by request_mutex.

b049453221 libceph: request a new osdmap if lingering request maps to no osd
This commit does two things.  First, if there are any homeless
lingering requests, we now request a new osdmap even if the osdmap that
is being processed brought no changes, i.e. if a given lingering
request turned homeless in one of the previous epochs and remained
homeless in the current epoch.  Not doing so leaves us with a stale
osdmap and as a result we may miss our window for reestablishing the
watch and lose notifies.

MON=1 OSD=1:

    # cat linger-needmap.sh
    #!/bin/bash
    rbd create --size 1 test
    DEV=$(rbd map test)
    ceph osd out 0
    rbd map dne/dne # obtain a new osdmap as a side effect (!)
    sleep 1
    ceph osd in 0
    rbd resize --size 2 test
    # rbd info test | grep size -> 2M
    # blockdev --getsize $DEV -> 1M

N.B.: Not obtaining a new osdmap in between "osd out" and "osd in"
above is enough to make it miss that resize notify, but that is a
bug^Wlimitation of ceph watch/notify v1.

Second, homeless lingering requests are now kicked just like those
lingering requests whose mapping has changed.  This is mainly to
recognize that a homeless lingering request makes no sense and to
preserve the invariant that a registered lingering request is not
sitting on any of r_req_lru_item lists.  This spares us a WARN_ON,
which commit ba9d114ec5 ("libceph: clear r_req_lru_item in
__unregister_linger_request()") tried to fix the _wrong_ way.

f25bf74c88 ARM: dts: Fix WLAN interrupt line for AM335x EVM-SK
While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO
controllers are numbered from 0 on AM335x and from 1 on OMAP. But when
the configuration for the TI WLAN controllers was converted from
platform data to device tree, this detail was overlooked, as 10 boards
were using OMAP with the WL12xx and WL18xx controllers, and only one
was based on AM335x.

This invalid configuration prevents the WL1271 module on the AM335x
EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver.

The DTS must be corrected to use the correct GPIO controller.
