git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig
Pull localmodconfig fixes from Steven Rostedt:
"Bill Pemberton added some changes to make streamline-config.pl work
again as a stand-alone tool (outside of make localmodconfig).
Also, he added a couple of updates to make the code be more "Perl
proper".
Added last minute fix to localyesconfig, that was the same as
localmodconfig since v3.2, due to a change in the makefiles."
* tag 'localmodconfig-v3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig:
localmodconfig: Fix localyesconfig to set to 'y' not 'm'
localmodconfig: Use my variable for loop in streamline_config.pl

Commit 8aac4cc3a9d7 ("IB/qib: RCU locking for MR validation") introduced
a bug that broke user post sends. The proper validation of the MR
was lost in the patch.
This patch corrects that validation.

The kbuild target 'localyesconfig' has been same as 'localmodconfig'
since the commit 50bce3e "kconfig/streamline_config.pl: merge
local{mod,yes}config". The commit expects this script generates
different configure depending on target, but it was not yet implemented.
So I added code that sets to 'yes' when target is 'localyesconfig'.

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:
1) Patchset from Henrik Rydberg which substantially reduces irqsoff
latency for all input devices. In addition to that, Henrik reworked
multitouch handling in order to reduce runtime memory consumption.
This patchset touches code in Input subsystem as well. All the
changes have been Acked by Dmitry, and we agreed to do it this way
due to inter-dependencies between the patchset and subsequent
changes in HID subsystem.
2) Rework, clenaups and a lot of fixes to picolcd driver by Bruno
Prémont.
3) Core report descriptor handling fix which fixes resume issue on some
devices, by Kevin Daughtridge
4) hidraw fixes by Alexey Khoroshilov and Ratan Nalumasu

Pull GFS2 updates from Steven Whitehouse:
"The major feature this time is the "rbm" conversion in the resource
group code. The new struct gfs2_rbm specifies the location of an
allocatable block in (resource group, bitmap, offset) form. There are
a number of added helper functions, and later patches then rewrite
some of the resource group code in terms of this new structure. Not
only does this give us a nice code clean up, but it also removes some
of the previous restrictions where extents could not cross bitmap
boundaries, for example.
In addition to that, there are a few bug fixes and clean ups, but the
rbm work is by far the majority of this patch set in terms of number
of changed lines."

'uclogic', 'wacom' and 'wiimote' into for-linus

The current SPI driver has many issues. Examples are:
* Segfaulting on most transfers due to expecting all transfers to have
both RX and TX buffers.
* Hanging on TX transfers since the whole driver flow is driven by RX
DMA completion, but the HW is only told to enable RX for RX transfers.
* Use of clk_disable_unprepare() from atomic context.
* Once those and other minor issues are fixed, the driver still doesn't
actually work.
* The driver also implements a deprecated API to the SPI core.
For this reason, simply remove the driver completely. This has two
advantages:
1) This will remove the last use of Tegra's <mach/dma.h>, which will
allow that file to be removed, which is required for single zImage
work.
2) The downstream driver is significaly different from the current
code. I believe a patch to re-add the downstream driver (with
appropriate cleanup) will be much simpler to review if it's a new
file rather than randomly interspered with essentially unrelated
existing code.

Besides the CPU and DDR PLLs, the CPU and DDR frequencies
can be derived from other PLLs in the SRIF block on the
AR934x SoCs. The current code does not checks if the SRIF
PLLs are used and this can lead to incorrectly calculated
CPU/DDR frequencies.
Fix it by calculating the frequencies from SRIF PLLs if
those are used on a given board.

The current dividers in the code are wrong and this
leads to broken CPU frequency calculation on boards
where the fractional part is used.
For example, if the SoC is running from a 40MHz
reference clock, refdiv=1, nint=14, outdiv=0 and
nfrac=31 the real frequency is 579.375MHz but the
current code calculates 569.687MHz instead.
Because the system time is indirectly related to
the CPU frequency the broken computation causes
drift in the system time.
The correct divider is 2^6 for the CPU PLL and 2^10
for the DDR PLL. Use the correct values to fix the
issue.

While calculating the mac address the pointer for the current octet was
never reset back to the least significant one after being decremented
because of an octet overflow. This resulted in the code continuing to
increment at the current octet, potentially generating duplicate or
invalid mac addresses.
As a second issue the pointer was allowed to advance up to the most
significant octet, modifying the OUI, and potentially changing the type
of mac address.
Rewrite the code so it resets the pointer to the least significant
in each outer loop step, and bails out when the least significant octet
of the OUI is reached.

In the current driver, the SENSE_PORT firmware command is issued as a
"wrapped" command, but the command handling code doesn't have a
wrapper, so it will never do anything other than log an error message.
The latest ConnectX-3 2.11.500 firmware reports the SENSE_PORT
capability even in multi-function (SR-IOV) mode, so the driver will
try to issue the command.
At least until the driver has a proper wrapper for SENSE_PORT, make
sure we disable the command for multi-function devices.

Instead of having a hard-coded "PCI device ID != 0x1003" (which
obviously breaks as newer devices with ID != 0x1003 become available),
instead let's set a flag in our PCI device table for the older devices
where we're supposed to force using SENSE_PORT. This also avoids
enabling SENSE_PORT for virtual functions by mistake.

The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.
usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
controller, and pinmux/control device.
Original driver by Simon Arlott.
Rewrite including GPIO chip device by Chris Boot.
Upstreaming changes by Stephen Warren:
* Wrote DT binding documentation.
* Changed brcm,function to an integer to more directly match the
datasheet, and to match brcm,pins being an integer.
* Implemented pull-up/down pin config.
* Removed read-only DT property and related code. The restriction this
implemented are driven by the board, not the GPIO HW block, so don't
really make sense of a HW block binding, were in general incomplete
(since they could only know about the few pins hard-coded into the
Raspberry Pi B board design and not the uncommitted GPIOS), and are
better represented simply by not writing incorrect data into pin
configuration nodes.
* Don't set GPIO_IN function select in gpio_request_enable() to avoid
glitches; defer this to gpio_set_direction(). Consequently, removed
empty bcm2835_pmx_gpio_request_enable().
* Simplified enabled_irq_map[]; make it explicitly 1 entry per bank.
* Lifted use of enabled_irq_map[] outside the per-interrupt loop in
IRQ handler, thus fixing an issue where the code was indexing into
enabled_irq_map[] by intra-bank GPIO ID, not global GPIO ID.
* Removed locking in IRQ handler, since all other code uses
spin_lock_irqsave() and so guarantees it doesn't run concurrently
with the handler.
* Moved duplicated BUILD_BUG_ON()s into probe(). Also check size of
bcm2835_gpio_pins[].
* Remove range-checking from bcm2835_pctl_get_groups_count() since we've
decided to trust the pinctrl core.
* Made bcm2835_pmx_gpio_disable_free() call bcm2835_pinctrl_fsel_set()
directly for simplicity.
* Fixed body of dt_free_map() to match latest dt_node_to_map().
* Removed GPIO ownership check from bcm2835_pmx_enable() since the pinctrl
core owns doing this.
* Made irq_chip and pinctrl_gpio_range .name == MODULE_NAME so it's more
descriptive.
* Simplified remove(); removed call to non-existent
pinctrl_remove_gpio_range(), remove early return on error.
* Don't force gpiochip's base to 0. Set gpio_range.base to gpiochip's
base GPIO number.
* Error-handling cleanups in probe().
* Switched to module_platform_driver() rather than open-coding.
* Made pin, group, and function names lower-case.
* s/broadcom/brcm/ in DT property names.
* s/2708/2835/.
* Fixed a couple minor checkpatch warnings, and other minor cleanup.

On an SR-IOV master device, __mlx4_init_one() calls mlx4_init_hca()
before mlx4_multi_func_init(). However, for unlucky configurations,
mlx4_init_hca() might call mlx4_SENSE_PORT() (via mlx4_dev_cap()), and
that calls mlx4_cmd_imm() with MLX4_CMD_WRAPPED set.
However, on a multifunction device with MLX4_CMD_WRAPPED, __mlx4_cmd()
calls into mlx4_slave_cmd(), and that immediately tries to do
down(&priv->cmd.slave_sem);
but priv->cmd.slave_sem isn't initialized until mlx4_multi_func_init()
(which we haven't called yet). The next thing it tries to do is access
priv->mfunc.vhcr, but that hasn't been allocated yet.
Fix this by moving the initialization of slave_sem and vhcr up into
mlx4_cmd_init(). Also, since slave_sem is really just being used as a
mutex, convert it into a slave_cmd_mutex.

When we have VFs and PFs on same host, the VFs are activated within
the mlx4_core module before the mlx4_ib kernel module is loaded.
When the mlx4_ib module initializes the PF (master), it now creates
MAD paravirtualization contexts for any VFs that already active.

Previously, the structure of a guest's proxy QPs followed the
structure of the PPF special qps (qp0 port 1, qp0 port 2, qp1 port 1,
qp1 port 2, ...). The guest then did offset calculations on the
sqp_base qp number that the PPF passed to it in QUERY_FUNC_CAP().
This is now changed so that the guest does no offset calculations
regarding proxy or tunnel QPs to use. This change frees the PPF from
needing to adhere to a specific order in allocating proxy and tunnel
QPs.
Now QUERY_FUNC_CAP provides each port individually with its proxy
qp0, proxy qp1, tunnel qp0, and tunnel qp1 QP numbers, and these are
used directly where required (with no offset calculations).
To accomplish this change, several fields were added to the phys_caps
structure for use by the PPF and by non-SR-IOV mode:
base_sqpn -- in non-sriov mode, this was formerly sqp_start.
base_proxy_sqpn -- the first physical proxy qp number -- used by PPF
base_tunnel_sqpn -- the first physical tunnel qp number -- used by PPF.
The current code in the PPF still adheres to the previous layout of
sqps, proxy-sqps and tunnel-sqps. However, the PPF can change this
layout without affecting VF or (paravirtualized) PF code.

This is necessary in order to support > 1 VF/PF in a VM for software
that uses the node guid as a discriminator, such as librdmacm.

Remove the error returns for IB ports from mlx4_ib_add,
mlx4_INIT_PORT_wrapper, and mlx4_CLOSE_PORT_wrapper.
Currently, SRIOV is supported only for devices for which the
link layer is IB on all ports; RoCE support will be added later.

1. Allow only master to change node description.
2. Prevent AH leakage in send mads.
3. Take device part number from PCI structure, so that guests see the
VF part number (and not the PF part number).
4. Place the device revision ID into caps structure at startup.
5. SET_PORT in update_gids_task needs to go through wrapper on master.
6. In mlx4_ib_event(), PORT_MGMT_EVENT needs be handled in a work
queue on the master, since it propagates events to slaves using
GEN_EQE.
7. Do not support FMR on slaves.
8. Add spinlock to slave_event(), since it is called both in interrupt
context and in process context (due to 6 above, and also if
smp_snoop is used). This fix was found and implemented by Saeed
