This updates the defconfig for the U8500 platform with
some of the changes from the v5.9 and v5.10 kernel
cycles:
- No need to select the schedutil cpufreq governor
because it is the default now.
- Enable the CY8CTMA140 touchscreen as used on the
Samsung Skomer GT-S7710.
- Enable the Samsung S6E63M0 DSI panel as used on
the Samsung Golden GT-I8810.
- Enable the KTD253 backlight as used on the Samsung
Skomer GT-S7710.
- Drop CONFIG_USB as we only use the gadget mode of

- Add selection of the CONFIG_LEDS_LP55XX_COMMON
lest the LP5521 LEDs will not work.
- Move the config entry for CONFIG_DEBUG_FS.

arm64: defconfig: Enable QCOM_SCM as builtin
The Qualcomm SCM driver was never explicitly enabled in the defconfig.
Instead it was (apparently) selected by DRM_MSM and by the recent change
to make it tristate now became =m.
Unfortunately this removes the ability for PINCTRL_MSM and ARM_SMMU to
be =y and with deferred_probe_timeout defaulting to 0 this means that
things such as UART, USB, PCIe and SDHCI probes with their dependencies
ignored.
The lack of pinctrl results in invalid pin configuration and the lack of
iommu results in the system locking up as soon as any form of data
transfer is attempted from any of the affected peripherals.
Mark QCOM_SCM as builtin, to avoid this.

Further there was only one user ever.
- Android's loadfont, busybox and console-tools only ever use OP_GET
and OP_SET
- fbset documentation only mentions the kernel cmdline font: option,
not anything else.
- systemd used OP_COPY before release 232 published in Nov 2016
Now unfortunately the crucial report seems to have gone down with
gmane, and the commit message doesn't say much. But the pull request
hints at OP_COPY being broken
https://github.com/systemd/systemd/pull/3651
So in other words, this never worked, and the only project which
foolishly every tried to use it, realized that rather quickly too.
Instead of trying to fix security issues here on dead code by adding
missing checks, fix the entire thing by removing the functionality.
Note that systemd code using the OP_COPY function ignored the return
value, so it doesn't matter what we're doing here really - just in
case a lone server somewhere happens to be extremely unlucky and
running an affected old version of systemd. The relevant code from
font_copy_to_all_vcs() in systemd was:
/* copy font from active VT, where the font was uploaded to */
cfo.op = KD_FONT_OP_COPY;
cfo.height = vcs.v_active-1; /* tty1 == index 0 */
(void) ioctl(vcfd, KDFONTOP, &cfo);
Note this just disables the ioctl, garbage collecting the now unused
callbacks is left for -next.

[ Side note: Christoph initially had a scripted "move everything over"

discourage splice() on random files. So this does just the minimal
basic core set of proc file op conversions.
For completeness, and in case people care, that script was

futex: Handle transient "ownerless" rtmutex state correctly
Gratian managed to trigger the BUG_ON(!newowner) in fixup_pi_state_owner().
This is one possible chain of events leading to this:
Task Prio Operation
T1 120 lock(F)
T2 120 lock(F) -> blocks (top waiter)
T3 50 (RT) lock(F) -> boosts T1 and blocks (new top waiter)
XX timeout/ -> wakes T2
signal
T1 50 unlock(F) -> wakes T3 (rtmutex->owner == NULL, waiter bit is set)
T2 120 cleanup -> try_to_take_mutex() fails because T3 is the top waiter
and the lower priority T2 cannot steal the lock.
-> fixup_pi_state_owner() sees newowner == NULL -> BUG_ON()
The comment states that this is invalid and rt_mutex_real_owner() must
return a non NULL owner when the trylock failed, but in case of a queued
and woken up waiter rt_mutex_real_owner() == NULL is a valid transient
state. The higher priority waiter has simply not yet managed to take over
the rtmutex.
The BUG_ON() is therefore wrong and this is just another retry condition in
fixup_pi_state_owner().
Drop the locks, so that T3 can make progress, and then try the fixup again.
Gratian provided a great analysis, traces and a reproducer. The analysis is
to the point, but it confused the hell out of that tglx dude who had to
page in all the futex horrors again. Condensed version is above.

perf/core: Fix a memory leak in perf_event_parse_addr_filter()
As shown through runtime testing, the "filename" allocation is not
always freed in perf_event_parse_addr_filter().
There are three possible ways that this could happen:
- It could be allocated twice on subsequent iterations through the loop,
- or leaked on the success path,
- or on the failure path.
Clean up the code flow to make it obvious that 'filename' is always
freed in the reallocation path and in the two return paths as well.
We rely on the fact that kfree(NULL) is NOP and filename is initialized
with NULL.
This fixes the leak. No other side effects expected.

null_blk: Fix scheduling in atomic with zoned mode
Commit
aa1c09cb65e2 ("null_blk: Fix locking in zoned mode") changed
zone locking to using the potentially sleeping wait_on_bit_io()
function. This is acceptable when memory backing is enabled as the
device queue is in that case marked as blocking, but this triggers a
scheduling while in atomic context with memory backing disabled.
Fix this by relying solely on the device zone spinlock for zone
information protection without temporarily releasing this lock around
null_process_cmd() execution in null_zone_write(). This is OK to do
since when memory backing is disabled, command processing does not
block and the memory backing lock nullb->lock is unused. This solution
avoids the overhead of having to mark a zoned null_blk device queue as
blocking when memory backing is unused.
This patch also adds comments to the zone locking code to explain the
unusual locking scheme.

In this situation, the bios_event_log pointer in the tpm_bios_log struct
was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. This was
due to the following kmemdup() in tpm_read_log_efi():
int tpm_read_log_efi(struct tpm_chip *chip)
{
...
/* malloc EventLog space */
log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL);
if (!log->bios_event_log) {
ret = -ENOMEM;
goto out;
}
...
}
When log_size is zero, due to an empty event log from firmware,
ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the
binary_bios_measurements file, the tpm2_bios_measurements_start()
function does not perform a ZERO_OR_NULL_PTR() check on the
bios_event_log pointer before dereferencing it.
Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of
the bios_event_log pointer, simply avoid creating the
binary_bios_measurements_file as is done in other event log retrieval
backends.
Explicitly ignore all of the events in the final event log when the main
event log is empty. The list of events in the final event log cannot be
accurately parsed without referring to the first event in the main event
log (the event log header) so the final event log is useless in such a
situation.

tpm_tis: Disable interrupts on ThinkPad T490s
There is a misconfiguration in the bios of the gpio pin used for the
interrupt in the T490s. When interrupts are enabled in the tpm_tis
driver code this results in an interrupt storm. This was initially
reported when we attempted to enable the interrupt code in the tpm_tis
driver, which previously wasn't setting a flag to enable it. Due to
the reports of the interrupt storm that code was reverted and we went back
to polling instead of using interrupts. Now that we know the T490s problem
is a firmware issue, add code to check if the system is a T490s and
disable interrupts if that is the case. This will allow us to enable
interrupts for everyone else. If the user has a fixed bios they can
force the enabling of interrupts with tpm_tis.interrupts=1 on the
kernel command line.

means in a write-request I2C_SLAVE_WRITE_REQUESTED should be reported
before any I2C_SLAVE_WRITE_RECEIVED.
