If nfsd needs to recall a delegation for some reason it implies that there is
contention on the file, so further delegations should not be handed out.
The current code fails to do so, and the result is effectively a
live-lock under some workloads: a client attempting a conflicting
operation on a read-delegated file receives NFS4ERR_DELAY and retries
the operation, but by the time it retries the server may already have
given out another delegation.
We could simply avoid delegations for (say) 30 seconds after any recall, but
this is probably too heavy handed.
We could keep a list of inodes (or inode numbers or filehandles) for recalled
delegations, but that requires memory allocation and searching.
The approach taken here is to use a bloom filter to record the filehandles
which are currently blocked from delegation, and to accept the cost of a few
false positives.
We have 2 bloom filters, each of which is valid for 30 seconds. When a
delegation is recalled the filehandle is added to one filter and will remain
disabled for between 30 and 60 seconds.
We keep a count of the number of filehandles that have been added, so when
that count is zero we can bypass all other tests.
The bloom filters have 256 bits and 3 hash functions. This should allow a
couple of dozen blocked filehandles with minimal false positives. If many
more filehandles are all blocked at once, behaviour will degrade towards
rejecting all delegations for between 30 and 60 seconds, then resetting and
allowing new delegations.

As reported by Niels, starting rfkill polling during device probe
(commit e2bc7c5, generally sane change) broke rfkill on rt2500pci
device. I considered that bug as some initalization issue, which
should be fixed on rt2500pci specific code. But after several
attempts (see bug report for details) we fail to find working solution.
Hence I decided to revert to old behaviour on rt2500pci to fix
regression.
Additionally patch also unregister rfkill on device remove instead
of ifconfig down, what was another issue introduced by bad commit.

Support for firmware rev 508+ was added years ago, but we never noticed
it reports channel in a different way for G-PHY devices. Instead of
offset from 2400 MHz it simply passes channel id (AKA hw_value).
So far it was (most probably) affecting monitor mode users only, but
the following recent commit made it noticeable for quite everybody:

The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) boots into a state that does
not actually require loading a firmware file. The vendors driver finds out
about this by checking a firmware state register, so this patch adds this here.
Finally, with this patch applied, my wifi dongle actually becomes

The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) currently does not
load. One thing observed is that the vendors driver detects EFUSE mode
for this device, but rt2800usb does not. This is due to rt2800usb
lacking a check for the firmware mode present in the vendors driver,
that this patch adopts for rt2800usb.
With this patch applied, the 'RF chipset' detection does no longer fail.

ahci_platform_get_resources handles resource management for
platform AHCI drivers, including getting a possible PHY
from the device tree. Since not all drivers need a PHY, it
ignores -ENODEV and -ENOSYS from devm_get_phy. However, when
the PHY subsystem is mistakenly disabled, -ENOSYS can be
returned even when a PHY is needed.
This patch modifies the -ENOSYS case to check if a "phys"
device tree node exists. If it exists, then clearly the PHY
subsystem is mistakenly disabled and the driver cannot work,
ahci_platform_get_resources will fail and propagate the error.

This solves a problem with building with CONFIG_SMP=n due to missing
sysram_base_addr (or sysram_ns_base_addr) variables.
The new setup method is more awkward than I'd like for it to be, but
it can't be done in init_early() since ioremap is not yet available,
but it needs to happen before SMP.

This addresses a section mismatch problem in the IM-PD1
driver in the Integrator/AP.
The IM-PD1 contains a VIC interrupt controller and therefore
the driver calls vic_init_cascaded() which is marked __init as
irqchips are simply not hot-pluggable and specifically the VIC
is assumed to initiate only on boot.
However the module driver model of the Integrator LM bus
assumes that logic tile drivers can be probed at runtime. This
is not really the case for IM-PD1: these tiles are detected at
boot and they cannot be plugged into a running system. Before
this patch it is of course possible to modprobe them later.
By first forcing the IM-PD1 to bool we make sure this driver
gets compiled into the kernel, and we know it will be probed
only at boot time when the tiles are detected, so we can tag
its probe function __init_refok as we know it won't be called
after boot now, and the section mismatch problem goes away.
As a side effect, sysfs binding from userspace becomes
impossible, so we tag the driver to suppress the bind/unbind
sysfs attributes.

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.
This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.
In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

We can only use CMA on systems that have an MMU, because of
the requirement to use memory migration. NOMMU systems are
rather constrained to start with, but it seems reasonable
to assume that DMA allocations can still succeed in the
constrained case for remoteproc on NOMMU, so this patch
changes the da8xx implementation to not rely on CMA when
the MMU is disabled.

The arm-cci code uses device tree helpers for initialization
that don't work on kernels built without CONFIG_OF. Further,
it contains an inline assembly in cci_enable_port_for_self()
that uses ARMv7 instructions and fails to build when targetting
other ARM instruction set versions.
This works around both issues by limiting the scope of the
Kconfig symbol to platforms that can actually build this driver

The dynamic relocation that the keystone platform performs
only works if we can pick the phys offset at boot time. It's
possible that there is another solution for this, but this
is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT

anyone would run a kernel without ARM_PATCH_PHYS_VIRT on

Commit d941f86fad41b ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:
arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.
This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

This patch fixes two problems: -
1) The device tree isn't currently providing sti-ethclk which is
required by the dwmac glue code to correctly configure the ethernet
PHY clock speed.
This means depending on what the bootloader/jtag has
configured this clock to, and what switch/hub the board is plugged
into you most likely will NOT successfully negotiate a ethernet link.
2) The stmmaceth clock was associated with the wrong clock. It was
referencing the PHY clock rather than the interconnect clock which
clocks the IP.
This patch also brings us closer to not having to boot the upstream
kernel with the clk_ignore_unused parameter.

the crossbar dts patches are not yet there, this causes a warning during
boot. So interrupts = < > property should be removed from DT and added
later by crossbar series.

Fix a parser-bug in the omap2 muxing code where muxtable-entries will be
wrongly selected if the requested muxname is a *prefix* of their
m0-entry and they have a matching mN-entry. Fix by additionally checking
that the length of the m0_entry is equal.
For example muxing of "dss_data2.dss_data2" on omap32xx will fail
because the prefix "dss_data2" will match the mux-entries "dss_data2" as
well as "dss_data20", with the suffix "dss_data2" matching m0 (for
dss_data2) and m4 (for dss_data20). Thus both are recognized as signal
path candidates:
Relevant muxentries from mux34xx.c:
_OMAP3_MUXENTRY(DSS_DATA20, 90,
"dss_data20", NULL, "mcspi3_somi", "dss_data2",
"gpio_90", NULL, NULL, "safe_mode"),
_OMAP3_MUXENTRY(DSS_DATA2, 72,
"dss_data2", NULL, NULL, NULL,
"gpio_72", NULL, NULL, "safe_mode"),
This will result in a failure to mux the pin at all:
_omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2
Patch should apply to linus' latest master down to rather old linux-2.6
trees.

into drm-next
two fixes for the deep color support in radeon.
* 'drm-next-3.16' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon: Bypass hw lut's for > 8 bpc framebuffer scanout.
drm/radeon: use pixel formats instead of depth/bpp

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
This is bigger because it regenerates the internal firmwares after a fix.
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/doc: update the thermal documentation
drm/nouveau/pwr: fix typo in fifo wrap handling
drm/nv50/disp: fix a potential oops in supervisor handling
drm/nouveau/disp/dp: don't touch link config after success
drm/nouveau/kms: reference vblank for crtc during pageflip.
drm/gk104/fb/ram: fixups from an earlier search+replace
drm/nv50/gr: remove an unneeded write while initialising PGRAPH
drm/nv50/gr: fix overlap while zeroing zcull regions
drm/gf100-/gr: report class data to host on fwmthd failure
drm/gk104/ibus: increase various random timeouts
drm/gk104/clk: only touch divider for mode we'll be using

Changes:
- Change the maintainer's address (the labri address will expire soon);
- Drop the note about not all families supporting all fan modes;
- Add a note about the reported RPM not being accurate when driven outside
the vbios-defined PWM range.
