A stress test (rapidly starting and killing hundreds of glxgears

"rm -rf" is bricking some peoples' laptops because of variables being
used to store non-reinitializable firmware driver data that's required
to POST the hardware.
These are 100% bugs, and they need to be fixed, but in the mean time it
shouldn't be easy to *accidentally* brick machines.
We have to have delete working, and picking which variables do and don't
work for deletion is quite intractable, so instead make everything
immutable by default (except for a whitelist), and make tools that
aren't quite so broad-spectrum unset the immutable flag.

We accidentally point both cfgcr registers for the second shared DPLL to
the same location in i915_reg.h. This results in a lot of hw pipe state
mismatches whenever we try to do a modeset that requires allocating the
DPLL to a CRTC:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in dpll_hw_state.cfgcr1 (expected 0x80000168, found 0x000004a5)
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 108000, found 49500)
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in port_clock (expected 108000, found 49500)
This usually ends up causing blank monitors, since the DPLL never can
get set to the right clock.

Prior to 4.3, openvswitch tunnel vports (vxlan, gre and geneve) could
transmit vxlan packets of any size, constrained only by the ability to
send out the resulting packets. 4.3 introduced netdevs corresponding
to tunnel vports. These netdevs have an MTU, which limits the size of
a packet that can be successfully encapsulated. The default MTU
values are low (1500 or less), which is awkwardly small in the context
of physical networks supporting jumbo frames, and leads to a
conspicuous change in behaviour for userspace.
Instead, set the MTU on openvswitch-created netdevs to be the relevant
maximum (i.e. the maximum IP packet size minus any relevant overhead),
effectively restoring the behaviour prior to 4.3.

Allow the MTU of geneve devices to be set to large values, in order to
exploit underlying networks with larger frame sizes.
GENEVE does not have a fixed encapsulation overhead (an openvswitch
rule can add variable length options), so there is no relevant maximum
MTU to enforce. A maximum of IP_MAX_MTU is used instead.
Encapsulated packets that are too big for the underlying network will
get dropped on the floor.

Allow the MTU of vxlan devices without an underlying device to be set
to larger values (up to a maximum based on IP packet limits and vxlan
overhead).
Previously, their MTUs could not be set to higher than the
conventional ethernet value of 1500. This is a very arbitrary value
in the context of vxlan, and prevented vxlan devices from being able
to take advantage of jumbo frames etc.
The default MTU remains 1500, for compatibility.

If we reload phy-twl4030-usb, we get a warning about unbalanced
pm_runtime_enable. Let's fix the issue and also fix idling of the
device on unload before we attempt to shut it down.
If we don't properly idle the PHY before shutting it down on removal,
the twl4030 ends up consuming about 62mW of extra power compared to
running idle with the module loaded.

If phy_pm_runtime_get_sync failed but we already
enable regulator, current code return directly without
doing regulator_disable. This patch fix this problem
and cleanup err handle of phy_power_on to be more readable.

A recent patch broke parsing the gain, offset, and threshold parameters
from device tree. Instead of setting the cached values and writing them
to the correct registers during probe, it would write the values from DT
into the register address variables and never write them to the chip
during normal operation.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
If COMPILE_TEST is enabled, relax the dependency on GPIOLIB for the
recently introduced or relaxed symbols TOUCHSCREEN_GOODIX and
TOUCHSCREEN_COLIBRI_VF50.

When the thermal subsystem is a loadable module, the u8500 driver
fails to build:
drivers/thermal/built-in.o: In function `db8500_thermal_probe':

drivers/thermal/built-in.o: In function `db8500_thermal_work':

This changes the symbol to a tristate, so Kconfig can track the

The spear thermal driver hides its suspend/resume function conditionally
based on CONFIG_PM, but references them based on CONFIG_PM_SLEEP, so
we get a warning if the former is set but the latter is not:
thermal/spear_thermal.c:58:12: warning: 'spear_thermal_suspend' defined but not used [-Wunused-function]
thermal/spear_thermal.c:75:12: warning: 'spear_thermal_resume' defined but not used [-Wunused-function]
This removes the #ifdef and instead uses a __maybe_uninitialized
annotation to avoid the warning and improve compile-time coverage.

This patch enables to use thermal-zone on DT if it was calles as

Previous style (= non thermal-zone) is still supported by

Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
API:
- Fix async algif_skcipher, it was broken by recent fixes.
- Fix potential race condition in algif_skcipher with ctx.
- Fix potential memory corruption in algif_skcipher.
- Add missing lock to crypto_user when doing an alg dump.
Drivers:
- marvell/cesa was testing the wrong variable for NULL after
allocation.
- Fix potential double-free in atmel-sha.
- Fix illegal call to sleepin function from atomic context in
atmel-sha"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: marvell/cesa - fix test in mv_cesa_dev_dma_init()
