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.

Looks like we still have the legacy clock alias name for

fix it for the device tree naming. There's no need to keep
the legacy naming as omap4 is DT only nowadays.

commit 104a43edb264321a4d41850e98153b4fa8a9ef42
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.

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.

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"

This patch fixes this issue by creating an fdb entry only if a

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
accesses happen.
Set looback_dev to NULL to trigger oopses instead of silent data corrupt
when we hit this class of bug.

When receiving or sending a packet a packet on a VLAN, the
vid has to be marked with the TAG flag in order to make any
component in batman-adv understand that the packet is coming
from a really tagged network.
This fix the Bridge Loop Avoidance behaviour which was not
able to send announces over VLAN interfaces.

o Move current_cpu_type() to a separate header file
o #ifdefing on supported CPU types lets modern GCC know that certain
code in callers may be discarded ideally turning current_cpu_type() into
a function returning a constant.
o Use current_cpu_type() rather than direct access to struct cpuinfo_mips.

Set "blocked by NMI" flag if EPT violation happens during IRET from NMI
otherwise NMI can be called recursively causing stack corruption.

There's no need to enclose this code within idef CONFIG_OF,
because the OF framework provides no-op stubs if CONFIG_OF=n.

Without this, legacy platforms that can boot with a multiplatform
kernel but that need the DTB to be appended, won't have a way to pass
firmware-set bootargs to the kernel.
This is needed to boot multi_v7_defconfig on snowball, for instance.

This fixes a multiplatform regression on the Ux500.
When compiling the Ux500 platforms in multiplatform configurations
both PL310_ERRATA_588369 and PL310_ERRATA_727915 would crash the
platform when trying to launch the init process.
The Ux500 cannot access the debug registers of the PL310, it will
just crash if you try this. So disable this by setting the debug
callback to NULL when initializing the l2x0 on this platform.

Caches in most systems are identical - but not always, so we can't avoid
the use of smp_call_function() by just looking at the boot CPU's data,
have to fiddle with preemption instead.
