The bitfield allocation function returns error condition
as a negative value, but in two cases its result
was assigned to an unsigned member of the hw_perf_event
structure, thus the error would not be ever detected.
Fixed by using an intermediate, signed variable.

Merge "Samsung DT 2nd updates for v3.17" from Kukjin Kim:
This is based on tags/exynos-power because this DT changes
are depending PMU cleanup.
Fixes boot for exynos5260 and exynos5410,
- Since exynos cannot boot without obtaining PMU address via
DT from now on, add PMU node for exynos5260 and exynos5410
For preparing exynos5250-spring,
- move max77686 and cypress,cyapa trackpad from exynos5250-
cros-common to exynos5250-snow DT file
(Note exynos5250-spring is not included in this branch yet)
For exynos3250,
- add TMU node and remove duplicated interrupt-parent
- add missing pinctrl property for uart0 and uart1
For exynos5250-smdk5250 board
- add max77686 pmic interrupt property which is connected to

INT3438 is the ADSP device on Wildcat Point platform
with 2 DW DMA engines built In. The DMA engines are
used for DSP FW loading and audio data transferring.
These DMA engine probing need the clock, without it,
probing may failed and can't go forward.

This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case #8000684337 and shared with the maintainer.

This patch removes the check for the number of mulitcast addresses
when using hash based filtering since it's not necessary. If the number
of multicast addresses in the list exceeds the number of multicast hash
bins, the bins will "fold" over into one of the bins configured and
enabled for the particular component instance.
The default number of maximum unicast addresses was changed from 32 to 1
since this number is not dependent on the component revision. The maximum
number of multicast and unicast addresses is dependent on the configuration
of the Synopsys EMAC configured by the SOC architect at the time the
features were selected and configured for a particular component. Sadly,
Synopsys does not provide a way to query the precise number supported
by a particular component, so we must fall back on a devicetree entry.
This configuration could vary from vendor to vendor (such as STMicro,
Altera, etc).
The multicast bins are set for every possible filtering case (including
no entries) - previously the bits were set only if multicast filter entries
were present.

The synopsys EMAC can be configured for different numbers of multicast hash
bins and perfect filter entries at device creation time and there's no way
to query this configuration information at runtime. As a result, a devicetree
parameter is required in order for the driver to program these filters
correctly for a particular device instance. This patch modifies the
10/100/1000 MAC software interface such that these configuration parameters
can be set at initialization time.

Commit 34c5bd66e5ed introduced the possibility that an
uninitialized pointer on the stack (orig_fp) can call into
sk_unattached_filter_destroy() when its value is non NULL.
Before that commit orig_fp was only destroyed in the same
block where it was assigned a valid BPF prog before. Fix it

According to the tps65090 data manual [0], the DCDC1 and DCDC2
step-down converters and the LDO's have a fixed output voltage.
Add this information to the driver since these fixed regulators
can be used as parent input supply for switches that don't have
an output voltage defined. So the regulator core needs to fetch
the FET parent output voltage if the child voltage is queried.

When using the FIFO-based ABI on x86_64, if the last port is at the
end of an event array page then sync_test_bit() on this port's event
word will read beyond the end of the page and in certain circumstances
this may fault.
The fault requires the following page in the kernel's direct mapping
to be not present, which would mean:
a) the array page is the last page of RAM; or
b) the following page is ballooned out /and/ it has been used for a
foreign mapping by a kernel driver (such as netback or blkback)
/and/ the grant has been unmapped.
Use the infrastructure added for arm64 to ensure that all bitops

Make the link between all the hardware drivers and DRM/KMS interface.
Create the driver itself and make it register all the sub-components.
Use GEM CMA helpers for buffer allocation.

In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.
The Coccinelle semantic patch that makes this change is as follows:
// <smpl>
@@ expression E1,E2; @@
(
!E1 & !E2
|
- !E1 & E2
+ !(E1 & E2)
)
// </smpl>

We can annonate the suspend/resume functions with '__maybe_unused' and get
rid of the ifdef, which makes the code smaller and simpler.

When a kernel has CONFIG_PM=y and CONFIG_PM_SLEEP=n the following warnings are
seen:
drivers/input/touchscreen/mcs5000_ts.c:252:12: warning: 'mcs5000_ts_suspend' defined but not used [-Wunused-function]
static int mcs5000_ts_suspend(struct device *dev)
^
drivers/input/touchscreen/mcs5000_ts.c:262:12: warning: 'mcs5000_ts_resume' defined but not used [-Wunused-function]
static int mcs5000_ts_resume(struct device *dev)
Protect the suspend/resume functions with CONFIG_PM_SLEEP in order to fix these
build warnings.
