Pull clk updates from Stephen Boyd:
"There's not much to see in the core framework this time around.
Instead the majority of the diff is the normal collection of driver
additions for new SoCs and non-critical clk data fixes and updates.
The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and
Unisoc support added a handful of big drivers for new SoCs but that's
not really the whole story because those new drivers tend to add large
numbers of lines of clk data. There's a handful of AT91 clk drivers
added this time around too and a bunch of improvements to drivers like
the i.MX driver. All around lots of updates and fixes in various clk
drivers which is good to see.
The core framework has only one real major change which has been
baking in next for the past couple months. It fixes the framework so
that it stops caching a clk's phase when the phase clk_op returns an
error. Before this change we would consider some negative errno as a
phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and
at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for
pll1443x table, and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need
to change ARM PLL frequency. Thus, we can support core running
above 1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate
for getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for
imx7d
- Remove PMC clks from Tegra clk driver
- Improved clock/reset handling for the Renesas R-Car USB2 Clock

Pull tracing updates from Steven Rostedt:
"New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and
reading as it acted like the normal producer/consumer. As the trace
file would not consume the data, the easy way of handling it was to
just disable writes to the ring buffer.
This came to a surprise to the BPF folks who complained about lost
events due to reading. This is no longer an issue. If someone wants
to keep the old disabling there's a new option "pause-on-trace"
that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be
traced by the function tracer.
Similar to set_ftrace_pid, which makes the function tracer only
trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced. Note,
sched_waking and sched_switch events may still be traced if one of
the tasks referenced by those events contains a PID that is allowed
to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file is
searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get
off debugfs (acked by Greg Kroah-Hartman)

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that do not
block interrupts. This makes us better at getting events to
userspace without blocking or disturbing new events arriving in the
same time. This was reviewed by the KFIFO maintainer Stefani. This
is a generic improvement which paves the road for similar
improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines and
giving them back, possibly reconfiguring them in the process: we
can now monitor that and not get stuck with stale static
information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could move
forward and *backward* in time, which probably would just cause
silent bugs and weird behaviour. In the long run we see two
relevant timestamps: ktime_get_ns() or the timestamp sometimes
provided by the GPIO hardware itself, if that exists.
- Device Tree overlay support for GPIO hogs. On systems that load
overlays, these overlays can now contain hogs, and will then be
respected.
- Handle pin control interaction with nonexisting pin ranges in the
GPIO library core instead of in the individual drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic MMIO GPIO
library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements, such as
blocking of idle on pending GPIO interrupts"

Revert "dm: always call blk_queue_split() in dm_process_bio()"
This reverts commit
effd58c95f277744f75d6e08819ac859dbcbd351.
blk_queue_split() is causing excessive IO splitting -- because
blk_max_size_offset() depends on 'chunk_sectors' limit being set and
if it isn't (as is the case for DM targets!) it falls back to
splitting on a 'max_sectors' boundary regardless of offset.
"Fix" this by reverting back to _not_ using blk_queue_split() in
dm_process_bio() for normal IO (reads and writes). Long-term fix is
still TBD but it should focus on training blk_max_size_offset() to
call into a DM provided hook (to call DM's max_io_len()).
Test results from simple misaligned IO test on 4-way dm-striped device
with chunksize of 128K and stripesize of 512K:

tracing: Do not allocate buffer in trace_find_next_entry() in atomic
When dumping out the trace data in latency format, a check is made to peek
at the next event to compare its timestamp to the current one, and if the
delta is of a greater size, it will add a marker showing so. But to do this,
it needs to save the current event otherwise peeking at the next event will
remove the current event. To save the event, a temp buffer is used, and if
the event is bigger than the temp buffer, the temp buffer is freed and a
bigger buffer is allocated.
This allocation is a problem when called in atomic context. The only way
this gets called via atomic context is via ftrace_dump(). Thus, use a static
buffer of 128 bytes (which covers most events), and if the event is bigger
than that, simply return NULL. The callers of trace_find_next_entry() need
to handle a NULL case, as that's what would happen if the allocation failed.

Pull xfs updates from Darrick Wong:
"There's a lot going on this cycle with cleanups in the log code, the
btree code, and the xattr code.
We're tightening of metadata validation and online fsck checking, and
introducing a common btree rebuilding library so that we can refactor
xfs_repair and introduce online repair in a future cycle.
We also fixed a few visible bugs -- most notably there's one in
getdents that we introduced in 5.6; and a fix for hangs when disabling
quotas.
This series has been running fstests & other QA in the background for
over a week and looks good so far.
I anticipate sending a second pull request next week. That batch will
change how xfs interacts with memory reclaim; how the log batches and
throttles log items; how hard writes near ENOSPC will try to squeeze
more space out of the filesystem; and hopefully fix the last of the
umount hangs after a catastrophic failure. That should ease a lot of
problems when running at the limits, but for now I'm leaving that in
for-next for another week to make sure we got all the subtleties
right.
Summary:
- Fix a hard to trigger race between iclog error checking and log
shutdown.
- Strengthen the AGF verifier.
- Ratelimit some of the more spammy error messages.
- Remove the icdinode uid/gid members and just use the ones in the
vfs inode.
- Hold ILOCK across insert/collapse range.
- Clean up the extended attribute interfaces.
- Clean up the attr flags mess.
- Restore PF_MEMALLOC after exiting xfsaild thread to avoid
triggering warnings in the process accounting code.
- Remove the flexibly-sized array from struct xfs_agfl to eliminate
compiler warnings about unaligned pointers and packed structures.
- Various macro and typedef removals.
- Stale metadata buffers if we decide they're corrupt outside of a
verifier.
- Check directory data/block/free block owners.
- Fix a UAF when aborting inactivation of a corrupt xattr fork.
- Teach online scrub to report failed directory and attr name lookups
as a metadata corruption instead of a runtime error.
- Avoid potential buffer overflows in sysfs files by using scnprintf.
- Fix a regression in getdents lookups due to a mistake in pointer
arithmetic.
- Refactor btree cursor private data structures to use anonymous
unions.
- Cleanups in the log unmounting code.
- Fix a potential mishandling of ENOMEM errors on multi-block
directory buffer lookups.
- Fix an incorrect test in the block allocation code.
- Cleanups and name prefix shortening in the scrub code.
- Introduce btree bulk loading code for online repair and scrub.
- Fix a quotaoff log item leak (and hang) when the fs goes down
midway through a quotaoff operation.
- Remove di_version from the incore inode.
- Refactor some of the log shutdown checking code.
- Record the forcing of the log unmount records in the log force
counters.
- Fix a longstanding bug where quotacheck would purge the
administrator's default quota grace interval and warning limits.
- Reduce memory usage when scrubbing directory and xattr trees.
- Don't let fsfreeze race with GETFSMAP or online scrub.
- Handle bio_add_page failures more gracefully in xlog_write_iclog"

Pull exec/proc updates from Eric Biederman:
"This contains two significant pieces of work: the work to sort out
proc_flush_task, and the work to solve a deadlock between strace and
exec.
Fixing proc_flush_task so that it no longer requires a persistent
mount makes improvements to proc possible. The removal of the
persistent mount solves an old regression that that caused the hidepid
mount option to only work on remount not on mount. The regression was
found and reported by the Android folks. This further allows Alexey
Gladkov's work making proc mount options specific to an individual
mount of proc to move forward.
The work on exec starts solving a long standing issue with exec that
it takes mutexes of blocking userspace applications, which makes exec
extremely deadlock prone. For the moment this adds a second mutex with
a narrower scope that handles all of the easy cases. Which makes the
tricky cases easy to spot. With a little luck the code to solve those
deadlocks will be ready by next merge window"

misc: pci_endpoint_test: Avoid using module parameter to determine irqtype
commit
e03327122e2c ("pci_endpoint_test: Add 2 ioctl commands")
uses module parameter 'irqtype' in pci_endpoint_test_set_irq()
to check if IRQ vectors of a particular type (MSI or MSI-X or
LEGACY) is already allocated. However with multi-function devices,
'irqtype' will not correctly reflect the IRQ type of the PCI device.
Fix it here by adding 'irqtype' for each PCI device to show the
IRQ type of a particular PCI device.
