Commit 76787b3b (ARM: OMAP2+: Remove board-4430sdp.c)
removed legacy booting in favor of device tree based booting
for 4430sdp. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.
I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp,
but the earlier version of this patch was tested by Luciano
Coelho. This version has left out the input logic for MMC CLK
line compared to the earlier version as that is not bidirectional,
and should be safe to do.

Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c)
removed legacy booting in favor of device tree based booting
for pandaboard. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.
The legacy muxing was setting pulls for GPIO 48 and 49, so let's
keep that behaviour for now to avoid further regressions for
BT and FM. Also input logic was enabled for MMC CLK line, but
I've verified that the input logic we don't need enabled for
CLK line as it's not bidirectional.
Also, we want to use non-removable instead of ti,non-removable
as the ti,non-removable also sets no_regulator_off_init which
is really not what we want as then wl12xx won't get powered
up and down which is needed for resetting it.
Note that looks like the WLAN interface fails to come up after
a warm reset, but that most likely was also happening with
the legacy booting and needs a separate fix.

KVM: nEPT: reset PDPTR register cache on nested vmentry emulation

KVM: x86 emulator: emulate RETF imm
Starting from v3.10 (probably commit f91e2590410b: "tty: Signal
foreground group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit. This breaks LSB test-suite, in particular test8 in
_exit.c and test40 in sigcon5.c.
Put the "!on_exit" check back to restore the old behaviour.
Review by Peter Hurley:
"Yes, this regression was introduced by me in that commit. The effect
of the regression is that ptys will receive a SIGCONT when, in similar
circumstances, ttys would not.
The fact that two test vectors accidentally tripped over this
regression suggests that some other apps may as well.
Thanks for catching this"

Current code looks like this:
WARN_ON(lock_policy_rwsem_write(cpu));
update_policy_cpu(policy, new_cpu);
unlock_policy_rwsem_write(cpu);
{lock|unlock}_policy_rwsem_write(cpu) takes/releases policy->cpu's rwsem.
Because cpu is changing with the call to update_policy_cpu(), the
unlock_policy_rwsem_write() will release the incorrect lock.
The right solution would be to release the same lock as was taken earlier. Also
update_policy_cpu() was also called from cpufreq_add_dev() without any locks and
so its better if we move this locking to inside update_policy_cpu().
This patch fixes a regression introduced in 3.12 by commit f9ba680d23

This broke after a recent change "cedb70a cpufreq: Split __cpufreq_remove_dev()
into two parts" from Srivatsa.
Consider a scenario where we have two CPUs in a policy (0 & 1) and we are
removing CPU 1. On the call to __cpufreq_remove_dev_prepare() we have cleared 1
from policy->cpus and now on a call to __cpufreq_remove_dev_finish() we read
cpumask_weight of policy->cpus, which will come as 1 and this code will behave
as if we are removing the last CPU from policy :)
Fix it by clearing the CPU mask in __cpufreq_remove_dev_finish() instead of
__cpufreq_remove_dev_prepare().

Patchwork: https://patchwork.linux-mips.org/patch/5833/
According to Prolific, several (unauthorized) cheap and less functional
clones of the PL2303HX chip are in circulation. [1]
I've had the chance to test such a cloned device and it turned out that
it doesn't support any baud rates above 115200 baud (original: 6 Mbaud)
It also doesn't support the divisior based baud rate encoding method,
so no continuous baud rate adjustment is possible.
Nevertheless, these devices have been working (unintentionally) with
the driver up to commit 61fa8d694b ("pl2303: also use the divisor based
baud rate encoding method for baud rates < 115200 with HX chips"), and
this commit broke support for them.
Fortunately, it is pretty simple to distinguish between the original
and the cloned HX chips, so I've added a check and an extra chip type
to keep the clones working.
The same check is used by the latest Prolific Windows driver, so it
should be solid.

After driver conversion to udc_start/udc_stop infrastructure (commit
"usb:hsotg:samsung: Use new udc_start and udc_stop callbacks"
f65f0f1098) the gadget unregistration function is almost always called
with 'driver' parameter being NULL, what caused that the unregistration
code has not been executed at all. This is a leftover from the earlier
verison of this function (which used simple start/stop interface), where
driver parameter was obligatory.
This patch removes the NULL check for the 'driver' pointer and removes
all dereferences of it. It also moves disabling voltage regulators out
of the atomic context, because handling regulators (which are usually
i2c devices) might require sleeping.

Gadgets endpoint driver data is a criteria to judge that
whether the endpoints are in use or not. When gadget gets
assigned an endpoint from endpoint list, they check its
driver data if the driver data is NULL.
If the driver data is not NULL then they regard it as in use.
Therefore all of gadgets should reset their endpoints driver
data to NULL as they are disabled. Otherwise it causes a leak
of endpoint resource.

The function returns a pointer. Hence return NULL instead of 0.

If dwc3_gadget_init_endpoint() fails after allocate some of the eps, we
need to free their memory to avoid leak.
