The host1x driver prints out "disassembly" dumps of the command FIFO

been quite difficult to read with unnecessary newlines and occasional
missing parentheses.
Fix these problems by using pr_cont to remove unnecessary newlines

The lockdep code had reported the following unsafe locking scenario:

lock(s_active#228);
lock(&bdev->bd_mutex/1);
lock(s_active#228);
lock(&bdev->bd_mutex);

The delay circuit used to support HS400 is calibrated based on two
additional clocks. When these clocks are not available and
FF_CLK_SW_RST_DIS is not set in CORE_HC_MODE, reset might fail. But on
some platforms this doesn't work properly and below dump can be seen in
the kernel log.

The calibration clocks for the delay circut should be enabled, as done in the
downstream kernel, in order for reset of the SDHCI not to fail on some Qualcomm
platforms (e.g. 8974pro). These patches makes it possible to reference these
clocks.
Bjorn Andersson (2):
mmc: sdhci-msm: Utilize bulk clo
By stuffing the runtime controlled clocks into a clk_bulk_data array we
can utilize the newly introduced bulk clock operations and clean up the
error paths. This allow us to handle additional clocks in subsequent
patch, without the added complexity.

Just wanted to send along my current time queue for 4.14.
Most of it is actually ksefltest related, so if you'd prefer I
can send those through Shuah.
Let me know if you have any feedback or objections.
thanks

These testcases are motivated by a recent alarmtimer regression, which
caused one-shot CLOCK_{BOOTTIME,REALTIME}_ALARM timers to become
periodic timers.
The new testcases are very similar to the existing testcases for
repeating timers. But rather than waiting for 5 alarms, t

Currently the alarmtimer registers a wake-up source unconditionally,
regardless of the system having a (wake-up capable) RTC or not.
Hence the alarmtimer will always show up in
/sys/kernel/debug/wakeup_sources, even if it is not available, and thus
cannot be a wake-up sou

On some systems, the kernel headers haven't been updated to include
ADJ_SETOFFSET, so define it in the test if needed.

Rather than printing an error inside the alarm signal handler, set a
flag that we check later. This keeps the test from spamming the console
every time the alarm fires early. It also fixes the test exiting with
error code 0 if this was the only test failure.

Enable high resolution timer mode to time SO_RCVTIMEO value used with
setsockopt(2) on AF_UNIX and AF_INET datagram sockets. By default,
SO_RCVTIMEO uses low resolution timer which is good for most of socket

Hello Dave,
Resending the patch series to include netdev mailing list with a
cover letter.
I am submitting 2 patch series to enable hires timer to timeout
datagram sockets (AF_UNIX & AF_INET domain) and test code to test
timeout accuracy on these sockets.
There has been a behavior change in 4.9
AF_UNIX and AF_INET datagram sockets use high resolution timer to time
SO_RCVTIMEO value used with setsockopt(2). This test checks for the
accuracy of kernel notifying these sockets timeout to application. Test
program has code to check AF_UNIX socket, however the kernel function used

On UEFI systems, the firmware may expose a Graphics Output Protocol (GOP)
instance to which the efifb driver attempts to attach in order to provide
a minimal, unaccelerated framebuffer. The GOP protocol itself is not very
sophisticated, and only describes the offset and size of the framebuffer
in m
On ARM, regions of memory that are described by UEFI as having special
significance to the firmware itself are omitted from the linear mapping.
This is necessary since we cannot guarantee that alternate mappings of
the same physical region will use attributes that are compatible with
the ones we us
The ARM EFI init code never assigns the config_table member of the
efi struct, which means the sysfs device node is missing, and other
in-kernel users will not work correctly. So add the missing assignment.
Note that, for now, the runtime and fw_vendor members are still
omitted. This is deliberate
