"Catalin's out enjoying the sunshine, so I'm sending the fixes for a

Pull tracing fixlet from Steven Rostedt:
"Joel Fernandes asked to add a feature in tracing that Android had its
own patch internally for. I took it back in 4.13. Now he realizes that
he had a mistake, and swapped the values from what Android had. This
means that the old Android tools will break when using a new kernel
that has the new feature on it.
The options are:
1. To swap it back to what Android wants.
2. Add a command line option or something to do the swap
3. Just let Android carry a patch that swaps it back
Since it requires setting a tracing option to enable this anyway, I
doubt there are other users of this than Android. Thus, I've decided
to take option 1. If someone else is actually depending on the order
that is in the kernel, then we will have to revert this change and go
to option 2 or 3"

Currently ftrace displays data in trace output like so:
_-----=> irqs-off
/ _----=> need-resched
| / _---=> hardirq/softirq
|| / _--=> preempt-depth
||| / delay
TASK-PID CPU TGID |||| TIMESTAMP FUNCTION
| | | | |||| | |
bash-1091 [000] ( 1091) d..2 28.313544: sched_switch:
However Android's trace visualization tools expect a slightly different
format due to an out-of-tree patch patch that was been carried for a
decade, notice that the TGID and CPU fields are reversed:
_-----=> irqs-off
/ _----=> need-resched
| / _---=> hardirq/softirq
|| / _--=> preempt-depth
||| / delay
TASK-PID TGID CPU |||| TIMESTAMP FUNCTION
| | | | |||| | |
bash-1091 ( 1091) [002] d..2 64.965177: sched_switch:
From kernel v4.13 onwards, during which TGID was introduced, tracing
with systrace on all Android kernels will break (most Android kernels
have been on 4.9 with Android patches, so this issues hasn't been seen
yet). From v4.13 onwards things will break.
The chrome browser's tracing tools also embed the systrace viewer which
uses the legacy TGID format and updates to that are known to be
difficult to make.
Considering this, I suggest we make this change to the upstream kernel
and backport it to all Android kernels. I believe this feature is merged
recently enough into the upstream kernel that it shouldn't be a problem.
Also logically, IMO it makes more sense to group the TGID with the
TASK-PID and the CPU after these.

In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:
http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57
Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:
/home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator. Stop.
When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:
\# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
\# using basic dep data
This is because `tools/build/Build.include' prints these '\#'
characters:
printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
printf '\# using basic dep data\n\n' >> $(dot-target).cmd; \
This completes commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd files
for future Make").

Dynamic ftrace requires modifying the code segments that are usually
set to read-only. To do this, a per arch function is called both before
and after the ftrace modifications are performed. The "before" function
will set kernel code text to read-write to allow for ftrace to make the
modifications, and the "after" function will set the kernel code text
back to "read-only" to keep the kernel code text protected.
The issue happens when dynamic ftrace is tested at boot up. The test is
done before the kernel code text has been set to read-only. But the
"before" and "after" calls are still performed. The "after" call will
change the kernel code text to read-only prematurely, and other boot
code that expects this code to be read-write will fail.
The solution is to add a variable that is set when the kernel code text
is expected to be converted to read-only, and make the ftrace "before"
and "after" calls do nothing if that variable is not yet set. This is
similar to the x86 solution from commit 162396309745 ("ftrace, x86:
make kernel text writable only for conversions").

It does not matter if the caller of may_use_simd() migrates to
another cpu after the call, but it is still important that the
kernel_neon_busy percpu instance that is read matches the cpu the
task is running on at the time of the read.
This means that raw_cpu_read() is not sufficient. kernel_neon_busy
may appear true if the caller migrates during the execution of
raw_cpu_read() and the next task to be scheduled in on the initial
cpu calls kernel_neon_begin().
This patch replaces raw_cpu_read() with this_cpu_read() to protect
against this race.

Since the code is common for all NOMMU builds usage of the isb was a
bad idea (please, note that isb also used in MPU related code which is
fine because MPU has dependency on CPU_V7/CPU_V7M), instead use more
robust instr_sync assembler macro.

uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be
indirectly controlled by user-space, hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap)
drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap)
drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report->field' (local cap)
drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap)
Fix this by sanitizing such structure fields before using them to index
report->field, field->usage and hid->collection
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Commit ac75a041048b ("HID: i2c-hid: fix size check and type usage") started
writing messages when the ret_size is <= 2 from i2c_master_recv. However, my
device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop
moving the pointing stick or touchpad. It varies, but you get ~50 messages
each time which spams the log hard.
[ 95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2)
This has also been observed with a i2c-ALP0017.
[ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2)
Only print the message when ret_size is totally invalid and less than 2 to cut
down on the log spam.

If pinctrl nodes for 100/200MHz are missing, the controller should
not select any mode which need signal frequencies 100MHz or higher.
To prevent such speed modes the driver currently uses the quirk flag
SDHCI_QUIRK2_NO_1_8_V. This works nicely for SD cards since 1.8V
signaling is required for all faster modes and slower modes use 3.3V
signaling only.
However, there are eMMC modes which use 1.8V signaling and run below
100MHz, e.g. DDR52 at 1.8V. With using SDHCI_QUIRK2_NO_1_8_V this
mode is prevented. When using a fixed 1.8V regulator as vqmmc-supply
the stack has no valid mode to use. In this tenuous situation the
kernel continuously prints voltage switching errors:
mmc1: Switching to 3.3V signalling voltage failed
Avoid using SDHCI_QUIRK2_NO_1_8_V and prevent faster modes by
altering the SDHCI capability register. With that the stack is able
to select 1.8V modes even if no faster pinctrl states are available:
# cat /sys/kernel/debug/mmc1/ios
...
timing spec: 8 (mmc DDR52)
signal voltage: 1 (1.80 V)
...

After commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume) the status of ACPI events
is not cleared any more when entering the ACPI S5 system state (power
off) which causes some systems to power up immediately after turing
off power in certain situations.
That is a functional regression, so address it by making the code
clear the status of all ACPI events again when entering S5 (for
system-wide suspend or hibernation the clearing of the status of all
events is not desirable, as it might cause the kernel to miss wakeup
events sometimes).

Pull scheduler fixes from Thomas Gleixner:
- The hopefully final fix for the reported race problems in
kthread_parkme(). The previous attempt still left a hole and was
partially wrong.
- Plug a race in the remote tick mechanism which triggers a warning
about updates not being done correctly. That's a false positive if
the race condition is hit as the remote CPU is idle. Plug it by
checking the condition again when holding run queue lock.
- Fix a bug in the utilization estimation of a run queue which causes
the estimation to be 0 when a run queue is throttled.
- Advance the global expiration of the period timer when the timer is
restarted after a idle period. Otherwise the expiry time is stale and
the timer fires prematurely.
- Cure the drift between the bandwidth timer and the runqueue
accounting, which leads to bogus throttling of runqueues
- Place the call to cpufreq_update_util() correctly so the function
will observe the correct number of running RT tasks and not a stale
one.
