The 2nd gmac of mediatek soc ethernet may not be connected to a PHY
and a phy-handle isn't always available.
Unfortunately, mt7530 dsa driver assumes that the 2nd gmac is always
connected to switch port 5 and setup mt7530 according to phy address
of 2nd gmac node, causing null pointer dereferencing when phy-handle
isn't defined in dts.
This commit fix this setup code by checking return value of
of_parse_phandle before using it.

Some of the mptcp logs didn't print out the format string:

accessing PHY registers
After the power-down bit is cleared, the chip internally triggers a
global reset. According to the KSZ9031 documentation, we have to wait at
least 1ms for the reset to finish.
If the chip is accessed during reset, read will return 0xffff, while
write will be ignored. Depending on the system performance and MDIO bus
speed, we may or may not run in to this issue.
This bug was discovered on an iMX6QP system with KSZ9031 PHY and
attached PHY interrupt line. If IRQ was used, the link status update was
lost. In polling mode, the link status update was always correct.
The investigation showed, that during a read-modify-write access, the
read returned 0xffff (while the chip was still in reset) and
corresponding write hit the chip _after_ reset and triggered (due to the
0xffff) another reset in an undocumented bit (register 0x1f, bit 1),
resulting in the next write being lost due to the new reset cycle.
This patch fixes the issue by adding a 1...2 ms sleep after the
genphy_resume().

Commit 9463c4455900 ("net: stmmac: dwmac1000: Clear unused address
entries") cleared the unused mac address entries, but introduced an
out-of bounds mac address register programming bug -- After setting
the secondary unicast mac addresses, the "reg" value has reached
netdev_uc_count() + 1, thus we should only clear address entries
if (addr < perfect_addr_number)

Userland already uses xattrs on cgroupfs for bookkeeping. This will
allow delegated cgroups to support such usages.

led to possible deadlock scenarios. Reverted.

to function call, expected 2, have 3
timer->timer_ops->set_load(timer->odt, 0, 0);
~~~~~~~~~~~~~~~~~~~~~~~~~~ ^
1 error generated.
This is due to commit 02e6d546e3bd ("clocksource/drivers/timer-ti-dm:
Enable autoreload in set_pwm") in the clockevents tree interacting with
commit e28edc571925 ("remoteproc/omap: Request a timer(s) for remoteproc
usage") from the rpmsg tree.
This should have been fixed during the merge of the remoteproc tree
since it happened after the clockevents tree merge; however, it does not
look like my email was noticed by either maintainer and I did not pay
attention when the pull was sent since I was on CC.

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:

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.

The clang check in the python setup.py file expected $CC to be just the
name of the compiler, not the compiler + options, i.e. all options were
expected to be passed in $CFLAGS, this ends up making it fail in systems
where CC is set to, e.g.:
"aarch64-linaro-linux-gcc --sysroot=/oe/build/tmp/work/juno-linaro-linux/perf/1.0-r9/recipe-sysroot"
Like this:
$ python3
>>> from subprocess import Popen

Python 3.8 changed the output of 'python-config --ldflags' to no longer
include the '-lpythonX.Y' flag (this apparently fixed an issue loading
modules with a statically linked Python executable). The libpython
feature check in linux/build/feature fails if the Python library is not
included in FEATURE_CHECK_LDFLAGS-libpython variable.
This adds a check in the Makefile to determine if PYTHON_CONFIG accepts
the '--embed' flag and passes that flag alongside '--ldflags' if so.
tools/perf is the only place the libpython feature check is used.

The kernel utilization metric does multiplexing currently and is somewhat
unreliable. The problem is that it uses two instances of the fixed counter,
and the kernel has to multipleplex which causes errors. So should use
CPU_CLK_UNHALTED.THREAD instead.
Before:
# perf stat -M Kernel_Utilization -- sleep 1
Performance counter stats for 'sleep 1':
1,419,425 cpu_clk_unhalted.ref_tsc:k
<not counted> cpu_clk_unhalted.ref_tsc (0.00%)
After:
# perf stat -M Kernel_Utilization -- sleep 1
Performance counter stats for 'sleep 1':
746,688 cpu_clk_unhalted.thread:k # 0.7 Kernel_Utilization
1,088,348 cpu_clk_unhalted.thread

perf list expects CPU events to be parseable by name, e.g.
# perf list | grep el-capacity-read
el-capacity-read OR cpu/el-capacity-read/ [Kernel PMU event]
But the event parser does not recognize them that way, e.g.
# perf test -v "Parse event"
<SNIP>
running test 54 'cycles//u'
running test 55 'cycles:k'
running test 0 'cpu/config=10,config1,config2=3,period=1000/u'

\___ parser error test child finished with 1
---- end ----
Parse event definition strings: FAILED!
This happens because the parser splits names by '-' in order to deal
with cache events. For example 'L1-dcache' is a token in
parse-events.l which is matched to 'L1-dcache-load-miss' by the
following rule:
PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT '-' PE_NAME_CACHE_OP_RESULT opt_event_config
And so there is special handling for 2-part PMU names i.e.
PE_PMU_EVENT_PRE '-' PE_PMU_EVENT_SUF sep_dc
but no handling for 3-part names, which are instead added as tokens e.g.
topdown-[a-z-]+
While it would be possible to add a rule for 3-part names, that would
not work if the first parts were also a valid PMU name e.g.
'el-capacity-read' would be matched to 'el-capacity' before the parser
reached the 3rd part.
The parser would need significant change to rationalize all this, so
instead fix for now by adding missing Intel CPU events with 3-part names
to the event parser as tokens.
Missing events were found by using:
grep -r EVENT_ATTR_STR arch/x86/events/intel/core.c
