Calling clk_set_min_rate() is no better than just calling
clk_set_rate() because MSM clock code already takes care of
calling the min_rate ops if the clock really needs
clk_set_min_rate() called on it.

Add calls to clk_prepare and unprepare so that MSM can migrate to
the common clock framework. We never unprepare the clocks until
driver remove because the clocks are enabled and disabled in irq
context. Finer grained power management is possible in the future
via runtime power management techniques.

Clocks are not clk_put() in this driver's error paths during
probe. The code that checks for clock errors also fails to
properly return the error code from the pclk member if it turns
out to be the failing clock, leading to potentially confusing
error values if the clk member is not an error pointer. Fix these
problems with devm_clk_get() and proper error checking.
Removing the clk_put() in msm_serial_remove() also points out
that msm_port is unused. Furthermore, msm_port is the wrong type
and so the clk_put() would be using the wrong pointer. Replace it
with the proper type and call uart_remove_one_port() to do the
proper cleanup.

Not all disks fill out the VPD pages correctly. Add a blacklist flag
that allows us ignore the SBC-3 VPD pages for a given device. The
BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages
scsi_device parameter to bypass VPD scanning.
Also blacklist the offending Seagate drive model.

====================
The following patchset contains five fixes for Netfilter/IPVS, they are:
* A skb leak fix in fragmentation handling in case that helpers are in place,
it occurs since the IPV6 NAT infrastructure, from Phil Oester.
* Fix SCTP port mangling in ICMP packets for IPVS, from Julian Anastasov.
* Fix event delivery in ctnetlink regarding the new connlabel infrastructure,
from Florian Westphal.
* Fix mangling in the SIP NAT helper, from Balazs Peter Odor.
* Fix crash in ipt_ULOG introduced while adding netnamespace support,

When compiling a MMU kernel with CPU_HAS_ADDRESS_SPACES=n (e.g. "MMU=y
allnoconfig": "echo CONFIG_MMU=y > allno.config && make KCONFIG_ALLCONFIG=1
allnoconfig"), we use plain "move" instead of "moves", and I got:
CC arch/m68k/lib/uaccess.o
{standard input}: Assembler messages:
{standard input}:47: Error: operands mismatch -- statement `move.b %a0,(%a1)' ignored
This happens because plain "move" doesn't support byte transfers between
memory and address registers, while "moves" does.
Fix the asm constraints for __generic_copy_from_user(),
__generic_copy_to_user(), and __clear_user() to only use data registers
when accessing userspace.
Also, relax the asm constraints for 16-bit userspace accesses in
__put_user() and __get_user(), as both "move" and "moves" do support
such transfers between memory and address registers.

Gcc may replace calls to standard string functions by open code and/or
calls to other standard string functions. If the replacement function is
not available out-of-line, link errors will happen.
To avoid this, the out-of-line versions were provided by
arch/m68k/lib/string.c, but they were usually not linked in anymore as
typically none of its symbols are referenced by built-in code.
However, if any module would need them, they would not be available.
Hence remove the inline strcpy() and strcat() implementations, remove
arch/m68k/lib/string.c, and let the generic string library code handle it.
Impact on a typical kernel build seems minimal or nonexistent:
- .text : 0x00001000 - 0x002aac74 (2728 KiB)
- .data : 0x002ada48 - 0x00392148 ( 914 KiB)
+ .text : 0x00001000 - 0x002aacf4 (2728 KiB)
+ .data : 0x002adac8 - 0x00392148 ( 914 KiB)

Add a pin control driver for the TZ1090's low power pins via the
powerdown controller SOC_GPIO_CONTROL registers.
These pins have individually controlled pull-up, and group controlled
schmitt, slew-rate, drive-strength, and power-on-start (pos).
The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
ir_mod_stable_out and ir_mod_power_out functions respectively. If no
function is set they remain in GPIO mode. These muxes can be overridden
by requesting them as GPIOs.

This patch series that implements MPIDR linearization through a simple
hashing algorithm and updates current cpu_{suspend}/{resume} code to use
the newly created hash structures to retrieve context pointers. It
represents a stepping stone for the implementation of power management code
on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and
Tegra, with processors hitting low-power states requiring warm-boot resume
through the cpu_resume code path.

To reduce pop noise during playback stream start and stop the codec needs
to have the digital_mute callback implemented.
The codec need to be muted before the CPU dai has been stopped (McPDM).
Stopping the McPDM will generate a pop on the codec since no signal on the
PDM bus means full negative amplitude.
By managing the mute/unmute state of the outputs we can decrease the amount
of pop noise when playback starts or stops.

Looking into the active_asids array is not enough, as we also need
to look into the reserved_asids array (they both represent processes
that are currently running).
Also, not holding the ASID allocator lock is racy, as another CPU
could schedule that process and trigger a rollover, making the erratum
workaround miss an IPI.
Exposing this outside of context.c is a little ugly on the side, so
let's define a new entry point that the erratum workaround can call
to obtain the cpumask.

On a CPU that never ran anything, both the active and reserved ASID
fields are set to zero. In this case the ASID_TO_IDX() macro will
return -1, which is not a very useful value to index a bitmap.
Instead of trying to offset the ASID so that ASID #1 is actually
bit 0 in the asid_map bitmap, just always ignore bit 0 and start
the search from bit 1. This makes the code a bit more readable,
and without risk of OoB access.

When a CPU is running a process, the ASID for that process is
held in a per-CPU variable (the "active ASIDs" array). When
the ASID allocator handles a rollover, it copies the active
ASIDs into a "reserved ASIDs" array to ensure that a process
currently running on another CPU will continue to run unaffected.
The active array is zero-ed to indicate that a rollover occurred.
Because of this mechanism, a reserved ASID is only remembered for
a single rollover. A subsequent rollover will completely refill
the reserved ASIDs array.
In a severely oversubscribed environment where a CPU can be
prevented from running for extended periods of time (think virtual
machines), the above has a horrible side effect:
[P{a} denotes process P running with ASID a]
CPU-0 CPU-1
A{x} [active = <x 0>]
[suspended] runs B{y} [active = <x y>]
[rollover:
active = <0 0>
reserved = <x y>]
runs B{y} [active = <0 y>
reserved = <x y>]
[rollover:
active = <0 0>
reserved = <0 y>]
runs C{x} [active = <0 x>]
[resumes]
runs A{x}
At that stage, both A and C have the same ASID, with deadly
consequences.
The fix is to preserve reserved ASIDs across rollovers if
the CPU doesn't have an active ASID when the rollover occurs.

When booting fewer cores than are physically present on a versatile
platform (e.g. when passing maxcpus=N on the command line), some
secondary cores may remain in the holding pen, which is marked __INIT,
as each CPU's gic cpumask is initialised to 0xff, and thus an IPI to any
CPU will wake up *all* secondaries. This behaviour is crucial to the GIC
cpumask self-discovery. Late in the boot process, the memory comprising
the holding pen will be released to the kernel for more general use, and
may be overwritten with arbitrary data, which can cause the held
secondaries to start behaving unpredictably. This can lead to all manner
of odd behaviour from the kernel.
As preventing cpus from entering the pen would require invasive changes
to the GIC driver and to existing dts used in the wild, we instead
remove the __INIT marker from the pen, keeping it around and leaving the
unused secondary CPUs dormant.

With this change, we no longer lose the innermost entry in the user-mode
part of the call chain. See also the x86 port, which includes the ip.
It's possible to partially work around this problem by post-processing
the data to use the PERF_SAMPLE_IP value, but this works only if the CPU
wasn't in the kernel when the sample was taken.

This patch adds primitive DT support to the max8973 regulator driver. None
of the configuration parameters, supported in the platform data are yet
available in DT, therefore no configuration is performed if booting with
no platform data. This means, that DT instantiation can only be used on
boards, where no run-time configuration of the chip is required. In such
cases the driver can be used to scale its output voltage. In the future
support for configuration parameters should be added.
