It is supposed that sar_base is initialized in irq_save_context, which
is called on CPU_CLUSTER_PM_ENTER notification. If this notification
has been missed and CPU_CLUSTER_PM_EXIT is received sar_base is NULL.

Fix it by calling CPU_CLUSTER_PM_{ENTER,EXIT} under the same condition.

Tony Lindgren 2cfeed3142 ARM: OMAP4: Fix clock_get error for GPMC during boot
Looks like we still have the legacy clock alias name for
omap4 GPMC (General Purpose Memory Controller), so let's
fix it for the device tree naming. There's no need to keep
the legacy naming as omap4 is DT only nowadays.

Without this fix we get the following error while booting:

Josh Wu db10e20117 iio: at91: fix adc_clk overflow
The adc_clk variable is currently defined using a 32-bits unsigned integer,
which will overflow under some very valid range of operations.

Such overflow will occur if, for example, the parent clock is set to a
20MHz frequency and the ADC startup time is larger than 215ns.

To fix this, introduce an intermediate variable holding the clock rate
in kHz.

Linus Torvalds 9baa505948 Three pstore fixes related to compression:
1) Better adjustment of size of compression buffer (was too big
    for EFIVARS backend resulting in compression failure
 2) Use zlib_inflateInit2 instead of zlib_inflateInit
 3) Don't print messages about compression failure.  They will
    waste space that may better be used to log console output
    leading to the crash.

Michael Chan 48a3056973 cnic: Fix crash in cnic_bnx2x_service_kcq()
commit 104a43edb2
    cnic: Use CHIP_NUM macros from bnx2x.h

changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not.  There is another place in cnic that is still using
the old method to determine if FCoE is supported or not.  The 2 methods
may not yield the same result after the network interface is brought down
and up.  This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.

The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro.  As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.

Andrea Adami d26b17edaf ARM: sa1100: collie.c: fall back to jedec_probe flash detection
Zaurus collie contains 2 LH28F640BFHE-PTTL90 (64M 4Mx16) and
at the moment cfi will not detect the collie NOR.
In the meanwhile we can revert to the jedec-probe map which has been
fixed with following commit:

mtd: jedec_probe: fix LH28F640BF definition
fe2f4c8e0b

Somehow this is unsatisfactory because the flash is mounted READ ONLY
(as from factory, with a RO cramfs)

J. Bruce Fields a0f6ed8ebe RPCSEC_GSS: fix crash on destroying gss auth
This fixes a regression since  eb6dc19d8e
"RPCSEC_GSS: Share all credential caches on a per-transport basis" which
could cause an occasional oops in the nfsd code (see below).

The problem was that an auth was left referencing a client that had been
freed.  To avoid this we need to ensure that auths are shared only
between descendants of a common client; the fact that a clone of an
rpc_client takes a reference on its parent then ensures that the parent
client will last as long as the auth.

Also add a comment explaining what I think was the intention of this
code.

in modern kernels it was never very much missed for.  /dev/random however
uses get_cycles() in the how the jitter in the interrupt timing contains

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.

Oleg Nesterov 03e1261778 tty: disassociate_ctty() sends the extra SIGCONT
Starting from v3.10 (probably commit f91e259041: "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"

after it has been freed that have not turned up because in most cases
the storage allocated to the loopback device is not reused, when those

Viresh Kumar 8efd57657d cpufreq: unlock correct rwsem while updating policy->cpu
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
(cpufreq: Extract the handover of policy cpu to a helper function).

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().
