With a 64-bit resource_size_t, we get a build warning on bcm63xx_spi_probe:
drivers/spi/spi-bcm63xx.c:565:16: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]
As we are printing a resource, we can just use the %pr format
specifier that pretty-prints the address and avoids the warning.

When submitting an identical spi_message multiple times via spi_sync
the spi_message.frame_length does not get reset to 0 in __spi_validate
before adding up all spi_transfer.len resulting in
frame_length > actual_length on all but the first spi_sync call.

bit aggressive and broke other devices.

Without quirk keyboard repeats '6' until volume control is used since it
indicates the key is pressed without ever releasing.

Since Linux gpio framework return 0 for output, 1 for input.
But HW use 0 stands for input, and 1 stands for output.
So use negative to correct it.
And gpio_chip.get is used to get input value, no need to get
output value, so removing it.

When building pinctrl-ssbi-gpio and pinctrl-ssbi-mpp for ARM64, we get
a compile warning about invalid types:
drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c: In function 'pm8xxx_gpio_probe':

drivers/pinctrl/qcom/pinctrl-ssbi-mpp.c:766:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
This changes the code so we cast the pointer to 'unsigned long', which
is the right thing to do here.

for_each_child_of_node performs an of_node_get on each iteration,
so of_node_put is required on break out of the loop.
This is done using Coccinelle. And semantic patch used for this is
as follows:

expression root,e;
local idexpression child;
@@
for_each_child_of_node(root, child) {

Originally OMAP MPUIO GPIO irqchip was implemented using Generic irq
chip, but after set of reworks Generic irq chip code was replaced by
common OMAP GPIO implementation and finally removed by
commit d2d05c65c40e ("gpio: omap: Fix regression for MPUIO interrupts").
Unfortunately, above commit left .irq_mask/unmask callbacks assigned
as below for MPUIO GPIO case:
irqc->irq_mask = irq_gc_mask_set_bit;
irqc->irq_unmask = irq_gc_mask_clr_bit;
This now causes boot failure on OMAP1 platforms, after
commit 450fa54cfd66 ("gpio: omap: convert to use generic irq handler")
which forces these callbacks to be called during GPIO IRQs mapping
from gpiochip_irq_map:

This is caused by the fact that at the moment some GPIO names are set
to NULL, there is a hole in linear representation of one GPI bank, see
drivers/gpio/gpio-lpc32xx.c / gpi_p3_names[] for details.
The same problem most probably affects also gpio-cs5535.c, see
cs5535_gpio_names[].

The tegra gpio driver creates the debugfs entry irrespective of
whether the device exists or not. This is enabled on an arm64_defconfig
and leaves an entry in debugfs on all platforms where it is not
useful. This patch fixes the issue by creating the entry only when
a device exists.

The remoteproc core uses a static ida named rproc_dev_index for
assigning an automatic index number to a registered remoteproc.
The ida core may allocate some internal idr cache layers and ida
bitmap upon any ida allocation, and all these layers are truely
freed only upon the ida destruction. The rproc_dev_index ida is
not destroyed at present, leading to a memory leak when using the
remoteproc core as a module and atleast one rproc device is
registered and unregistered.
Fix this by invoking ida_destroy() in the remoteproc core module
exit.

drivers/remoteproc/remoteproc_debugfs.c:167:9: warning: 'buf[4294967295u]' may be used uninitialized in this function [-Wmaybe-uninitialized]
I don't see anything in sys_write() that prevents us from
being called with a zero 'count' argument, so we should
add an extra check in rproc_recovery_write() to prevent the
access and avoid the warning.

Pull tracing fixes from Steven Rostedt:
"I found two minor bugs while doing development on the ring buffer
code.
The first is something that's been there since its creation. If a
reader reads a page out of the ring buffer before there's any events
on it, it can get an out of date timestamp for that event. It may be
off by a few microseconds, more if the first event gets discarded.
The fix was to only update the reader time stamp when it actually sees
an event on the page, instead of just reading the timestamp from the
page even if it has no events on it. That timestamp is still volatile
until an event is present.
The second bug is more recent. Instead of passing around parameters a
descriptor was made and the parameters are passed via a single
descriptor. This simplified the code a bit. But there was one place
that expected the parameter to be passed by value not reference (which
a descriptor now does). And it added to the length of the event,
which may be ignored later, but the length should not have been
increased. The only real problem with this bug is that it may
allocate more than was needed for the event"

Commit fcc742eaad7c "ring-buffer: Add event descriptor to simplify passing
data" added a descriptor that holds various data instead of passing around
several variables through parameters. The problem was that one of the
parameters was modified in a function and the code was designed not to have
an effect on that modified parameter. Now that the parameter is a
descriptor and any modifications to it are non-volatile, the size of the
data could be unnecessarily expanded.
Remove the extra space added if a timestamp was added and the event went
across the page.

Do not update the read stamp after swapping out the reader page from the
write buffer. If the reader page is swapped out of the buffer before an
event is written to it, then the read_stamp may get an out of date
timestamp, as the page timestamp is updated on the first commit to that
page.
rb_get_reader_page() only returns a page if it has an event on it, otherwise
it will return NULL. At that point, check if the page being returned has
events and has not been read yet. Then at that point update the read_stamp
to match the time stamp of the reader page.

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes

A couple of regression fixes, some more boards whitelisted for a hw bug
workaround, gr/ucode fixes for hangs a user is seeing.
The changes look larger than they actually are due to the ucode binaries
(*.fucN.h) being regenerated.

Each GPCCS unit was reading the mask from GPC0, which causes problems on
boards where some GPCs are missing PPCs.

There's a few places where we need to access a GPC register from ucode,
but outside of the falcon's io address space. To do this we need to
calculate the offset based on which GPC we're executing on.
This used to be done manually, but we've since found a "base" offset
that can be added by the hardware. To use this, an extra bit needs to
be set in the register address, which is what this macro achieves.
There should be no functional change from this commit.

No locking is required for the traversal of this list, as it only
happens during suspend/resume where nothing else can be executing.

On some cards it takes a relatively long time for the change
