allow doing DMA without a lockup in the l2x0 cache controller on the

This adds support for the touchscreen on Samsung s3c64xx.
The driver is completely untested but shows roughly how
it could be done, following the example of the at91 driver.
compared to the old plat-samsung/adc driver, there is
no support for prioritizing ts over other clients, nor
for oversampling. From my reading of the code, the
priorities didn't actually have any effect at all, but
the oversampling might be needed.
Verifying this driver is the main issue that is currently
holding up multiplatform support for s3c64xx, so any help
in testing is very much appreciated.
The current version uses the IS_REACHABLE() that is
going to be introduced in the linux-media tree, please
comment this out for testing.

ARM: s3c64xx: enable sparse IRQ support
This is another prerequisite for enabling multiplatform
support, and it is the part I am least certain about.
I assume it will cause the extra boot message "Cannot
allocate irq_descs @ IRQ%d, assuming pre-allocated" to
be printed, but otherwise work ok. This definitely needs
to be tested on real hardware to see if it works.

ARM: s3c64xx: prepare initcalls for multiplatform
In a multiplatform kernel, each initcall is run regardless
of the platform it is meant for, so it must not attempt to
access SoC-specific registers.
This adds 'if (soc_is_s3c64xx)' to all initcalls that are
specific to the s3c64xx platform, to prevent them from breaking
other platforms once we can build them into a combined kernel.

gpio: samsung: move gpio-samsung driver back to platform code
The gpio-samsung driver is special in the sense that it
interacts directly in multiple ways with the legacy platform
code for the s3c24xx and s3c64xx platforms. In contrast,
all devicetree based machines for Samsung, including the
ones on those two SoC families use a different driver.
The header files that define the interface between the platform
code and the gpio driver are not visible when building a
kernel for ARCH_MULTIPLATFORM, which prevents us from
turning on this option for s3c64xx.
To work around this, we now move the driver back into platform
code, from where it was originally moved to as part of commit 1b39d5f2cc5c28 ("gpio/samsung: gpio-samsung.c to support
Samsung GPIOs").
The long-term plan for this driver would be to remove it
entirely, after all Samsung machines have been converted
over to boot from DT, but there is currently no timeline
for when that might happen.

As a prerequisite for moving s3c64xx into multiplatform configurations,
we need to change the smartq audio driver to stop using hardcoded
gpio numbers from the header file, and instead pass the gpio data
through platform_data.
In order to do that, we also move the code to use module_platform_driver
and register the platform device using platform_device_register_simple
and register the gpios through the gpiod API.

The mach/*.h headers are now inaccessible to any external code,
so we can move them all into the mach-mmp directory itself
and remove the subdirectories.
A few headers are not used at all, so we remove them here.
The ssp.c driver in plat-pxa is the only remaining file including a
mach/*.h header from mmp. It actually doesn't need mach/hardware.h at
all, so we can remove the #include.
It is in principle possible to build an MMP kernel for
the mohawk CPU with the MMU code disabled, except for one
simple build error:
proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*ABS* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: undefined symbol L_PTE_USER used as an immediate value
This patch changes the proc-mohawk code to do the same as the
other CPUs and not try to actually do anything for the
cpu_mohawk_set_pte_ext function, which won't be used anyway.
In a multiplatform configuration, we may end up building a kernel for
both Marvell PJ1 and an ARMv4 CPU implementation. In that case, the
xscale-cp0 code is built with gcc -march=armv4{,t}, which results in a
build error from the coprocessor instructions.
Since we know this code will only have to run on an actual xscale
processor, we can simply build the entire file for ARMv5TE.
Related to this, we need to handle the iWMMXT initialization sequence
differently during boot, to ensure we don't try to touch xscale
specific registers on other CPUs from the xscale_cp0_init initcall.
cpu_is_xscale() used to be hardcoded to '1' in any configuration that
enables any XScale-compatible core, but this breaks once we can have a
combined kernel with MMP1 and something else.
In this patch, I replace the existing cpu_is_xscale() macro with a new
cpu_is_xscale_family() macro that evaluates true for xscale, xsc3 and
mohawk, which makes the behavior more deterministic.
The two existing users of cpu_is_xscale() are modified accordingly,
but slightly change behavior for kernels that enable CPU_MOHAWK without
also enabling CPU_XSCALE or CPU_XSC3. Previously, these would leave leave
PMD_BIT4 in the page tables untouched, now they clear it as we've always
done for kernels that enable both MOHAWK and the support for the older
CPU types.
Since the previous behavior was inconsistent, I assume it was
unintentional.
The mmp clock drivers currently hardcode the physical addresses for
the clock registers. This is generally a bad idea, and it also gets in
the way of multiplatform builds, which make the platform header files
inaccessible to device drivers.
To work around the header file problem, this patch changes the calling
convention so the three mmp clock drivers get initialized with the base
addresses as arguments from the platform code.
It would still be useful to have a larger rework of the clock drivers,
with DT integration to let the clocks actually be probed automatically,
and the base addresses passed as DT properties. I am unsure if anyone
is still interested in the mmp platform, so it is possible that this
won't happen.

target: fix COMPARE_AND_WRITE non zero SGL offset data corruption
target_core_sbc's compare_and_write functionality suffers from taking

This can happen with loopback and vhost-scsi fabric drivers when
SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.
Rather than writing all-zeroes as instructed with the -D file, it
corrupts the data in the sector by splicing some of the original
bytes in. The page of the first entry of cmd->t_data_sg includes the
CDB, and sg->offset is set to a position past the CDB. I presume that
sg->offset is also the right choice to use for subsequent sglist
members.

target: Fix race for SCF_COMPARE_AND_WRITE_POST checking
This patch addresses a race + use after free where the first

is rescheduled after the backend sends the secondary WRITE,
resulting in second stage compare_and_write_post() callback
completing in target_complete_ok_work() before the first

Because current code depends on checking se_cmd->se_cmd_flags
after return from se_cmd->transport_complete_callback(),
this results in first stage having SCF_COMPARE_AND_WRITE_POST
set, which incorrectly falls through into second stage CAW
processing code, eventually triggering a NULL pointer
dereference due to use after free.
To address this bug, pass in a new *post_ret parameter into
se_cmd->transport_complete_callback(), and depend upon this
value instead of ->se_cmd_flags to determine when to return
or fall through into ->queue_status() code for CAW.

allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
from the failure path, resulting in RX thread hanging
indefinately on iscsi_conn->rx_login_comp.
To address this bug, complete ->rx_login_complete for good
measure in the failure path, and immediately return from
RX thread context if connection state did not actually reach
full feature phase (TARG_CONN_STATE_LOGGED_IN).

Pull more power management and ACPI fixes from Rafael Wysocki:
"These fix one recent regression (cpufreq core), fix up two features
added recently (ACPI CPPC support, SCPI support in the arm_big_little
cpufreq driver) and fix three older bugs in the intel_pstate driver.
Specifics:
- Fix a recent regression in the cpufreq core causing it to fail to
clean up sysfs directories properly on cpufreq driver removal
(Viresh Kumar).
- Fix a build problem in the SCPI support code recently added to the
arm_big_little cpufreq driver (Punit Agrawal).
- Fix up the recently added CPPC cpufreq frontend to process the CPU
coordination information provided by the platform firmware
correctly (Ashwin Chaugule).
- Fix the intel_pstate driver to behave as intended when switched
over to the "performance" mode via sysfs if hardware-driven P-state
selection (HWP) is enabled (Alexandra Yates).
- Fix two rounding errors in the intel_pstate driver that sometimes
cause it to use lower P-states than requested (Prarit Bhargava)"
