ARM: video: mxs: Fix mxsfb misconfiguring VDCTRL0
The issue fixed by this patch manifests only then using X11
with mxsfb driver. The X11 will display either shifted image
or otherwise distorted image on the LCD.
The problem is that the X11 tries to reconfigure the framebuffer
and along the way calls fb_ops.fb_set_par() with X11's desired
configuration values. The field of particular interest is
fb_info->var.sync which contains non-standard values if
configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,
FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform
configuration. Both of these values are defined in the
include/linux/mxsfb.h file.
The driver interprets these values and configures the LCD controller
accordingly. Yet X11 only has access to the standard values for this
field defined in include/uapi/linux/fb.h and thus, unlike kernel,
omits these special values. This results in distorted image on the
LCD.
This patch moves these non-standard values into new field of the
mxsfb_platform_data structure so the driver can in turn check this
field instead of the video mode field for these specific portions.
Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix
instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

irqchip: Renesas IRQC driver
This patch adds a driver for external IRQ pins connected

The IRQC hardware block is used together with more

requires external IRQ trigger setup somewhere else
which in this particular case happens to be IRQC.
This driver implements the glue code needed to configure
IRQ trigger and also handle mask/unmask and demux of
external IRQ pins hooked up from the IRQC to the GIC.
Tested on r8a73a4 but is designed to work with a wide
range of SoCs. The driver requires one GIC SPI per
external IRQ pin to operate. Each driver instance
will handle up to 32 external IRQ pins.
The SoCs using this driver are currently mainly used

like static interrupt base address. DT support will
be added incrementally in the not so distant future.

The INTC hardware block usually contains a rather wide

to legacy interrupt controller support. On older SoCs
the INTC is used as a general purpose interrupt controller
both for external IRQ pins and on-chip devices.
On more recent ARM based SoCs with Cortex-A9 the main
interrupt controller is the GIC, but IRQ trigger setup
still need to happen in the INTC hardware block.
This driver implements the glue code needed to configure
IRQ trigger and also handle mask/unmask and demux of
external IRQ pins hooked up from the INTC to the GIC.
Tested on sh73a0 and r8a7779. The hardware varies quite
a bit with SoC model, for instance register width and
bitfield widths vary wildly. The driver requires one GIC
SPI per external IRQ pin to operate. Each driver instance
will handle up to 8 external IRQ pins.
The SoCs using this driver are currently mainly used

init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
cross-calls to do the MSR update. Which is not really valid at the
early resume stage, and the warning is quite reasonable. Now, it all
happens to _work_, for the simple reason that smp_call_function_single()

Users report that an extent map's list is still linked when it's actually

The story is that
a) when we're going to drop an extent map and may split this large one into
smaller ems, and if this large one is flagged as EXTENT_FLAG_LOGGING which means
that it's on the list to be logged, then the smaller ems split from it will also
be flagged as EXTENT_FLAG_LOGGING, and this is _not_ expected.
b) we'll keep ems from unlinking the list and freeing when they are flagged with
EXTENT_FLAG_LOGGING, because the log code holds one reference.
The end result is the warning, but the truth is that we set the flag
EXTENT_FLAG_LOGGING only during fsync.
So clear flag EXTENT_FLAG_LOGGING for extent maps split from a large one.

asm-generic/cmpxchg.h directly, which is currently only OpenRISC.

perf,x86: fix kernel crash with PEBS/BTS after suspend/resume
This patch fixes a kernel crash when using precise sampling (PEBS)
after a suspend/resume. Turns out the CPU notifier code is not invoked
on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly
by the kernel and keeps it power-on/resume value of 0 causing any PEBS
measurement to crash when running on CPU0.
The workaround is to add a hook in the actual resume code to restore
the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0,
the DS_AREA will be restored twice but this is harmless.

ARM: i.MX35: enable MAX clock
The i.MX35 has two bits per clock gate which are decoded as follows:
0b00 -> clock off
0b01 -> clock is on in run mode, off in wait/doze
0b10 -> clock is on in run/wait mode, off in doze
0b11 -> clock is always on
The reset value for the MAX clock is 0b10.
The MAX clock is needed by the SoC, yet unused in the Kernel, so the
common clock framework will disable it during late init time. It will
only disable clocks though which it detects as being turned on. This
detection is made depending on the lower bit of the gate. If the reset
value has been altered by the bootloader to 0b11 the clock framework
will detect the clock as turned on, yet unused, hence it will turn it
off and the system locks up.
This patch turns the MAX clock on unconditionally making the Kernel
independent of the bootloader.
