As described in the old comment dating back to
commit 6610e0893b8b ("RTC: Rework RTC code to use timerqueue for events")
from 2010, we have been living with a race window when setting alarm
with an expiry in the near future (i.e. next second).
With 1 second resolution, it can happen that the second ticks after the
check for the timer having expired, but before the alarm is actually set.
When this happen, no alarm IRQ is generated, at least not with some RTC
chips (isl12022 is an example of this).
With UIE RTC timer being implemented on top of alarm irq, being re-armed
every second, UIE will occasionally fail to work, as an alarm irq lost
due to this race will stop the re-arming loop.
For now, I have limited the additional expiry check to only be done for
alarms set to next seconds. I expect it should be good enough, although I
don't know if we can now for sure that systems with loads could end up
causing the same problems for alarms set 2 seconds or even longer in the
future.
I haven't been able to reproduce the problem with this check in place.

During kexec reboots, RTC alarms that are fired during the kernel
transition experience delayed execution. The new kernel would eventually
honor these alarms, but the interrupt handlers would only execute after
the driver probe is completed rather than at the intended alarm time.
This is because pending alarm interrupt status from the previous kernel
is not properly cleared during driver initialization, causing timing
discrepancies in alarm delivery.
To ensure precise alarm timing across kexec transitions, enhance the
probe function to:
1. Clear any pending alarm interrupt status from previous boot.
2. Detect existing valid alarms and preserve their state.
3. Re-enable alarm interrupts for future alarms.

Add support for the RTC found in the SpacemiT P1 PMIC. Initially
only setting and reading the time are supported.
The PMIC is implemented as a multi-function device. This RTC is
probed based on this driver being named in a MFD cell in the simple
MFD I2C driver.

Add read_alarm and set_alarm ops from the rtc framework.
The support of an alarm is handled by a kernel thread waiting in OP-TEE
for an asynchronous notification that comes in the interrupt
handler of the alarm interruption on OP-TEE secure world.
Once the notification arrives, the kernel thread previously suspended
is rescheduled (this is handled by the OP-TEE kernel driver) and comes
back with the alarm information to the kernel.
A second session is therefore needed to enable/disable/cancel a waiting
alarm event as the kernel thread stopped in OP-TEE takes a form of mutex
on the session and so no one can use this session in parallel.

PCF2127 can generate interrupt every full second or minute configured
from control and status register 1, bits MI (1) and SI (0).
On interrupt control register 2 bit MSF (7) is set and must be cleared
to continue normal operation.
While the driver never enables this interrupt on its own, users or
firmware may do so - e.g. as an easy way to test the interrupt.
Add preprocessor definition for MSF bit and include it in the irq
bitmask to ensure minute and second interrupts are cleared when fired.
This fixes an issue where the rtc enters a test mode and becomes
unresponsive after a second interrupt has fired and is not cleared in
time. In this state register writes to control registers have no
effect and the interrupt line is kept asserted [1]:
[1] userspace commands to put rtc into unresponsive state:
$ i2cget -f -y 2 0x51 0x00
0x04
$ i2cset -f -y 2 0x51 0x00 0x05 # set bit 0 SI
$ i2cget -f -y 2 0x51 0x00
0x84 # bit 8 EXT_TEST set
$ i2cset -f -y 2 0x51 0x00 0x05 # try overwrite control register
$ i2cget -f -y 2 0x51 0x00
0x84 # no change

Define a new, optional, callback that allows the driver to
specify how the return data buffer is allocated. If that callback
is set, mailbox/pcc.c is now responsible for reading from and
writing to the PCC shared buffer.
This also allows for proper checks of the Commnand complete flag
between the PCC sender and receiver.
For Type 4 channels, initialize the command complete flag prior
to accepting messages.
Since the mailbox does not know what memory allocation scheme
to use for response messages, the client now has an optional
callback that allows it to allocate the buffer for a response
message.
When an outbound message is written to the buffer, the mailbox
checks for the flag indicating the client wants an tx complete
notification via IRQ. Upon receipt of the interrupt It will
pair it with the outgoing message. The expected use is to
free the kernel memory buffer for the previous outgoing message.

vmd_msi_alloc() allocates struct vmd_irq and stashes it into
irq_data->chip_data associated with the VMD's interrupt domain.
vmd_msi_free() extracts the pointer by calling irq_get_chip_data() and
frees it.
irq_get_chip_data() returns the chip_data associated with the top interrupt
domain. This worked in the past because VMD's interrupt domain was the top
domain.
But d7d8ab87e3e7 ("PCI: vmd: Switch to msi_create_parent_irq_domain()")
changed the interrupt domain hierarchy so VMD's interrupt domain is not the
top domain anymore. irq_get_chip_data() now returns the chip_data at the
MSI devices' interrupt domains. It is therefore broken for vmd_msi_free()
to kfree() this chip_data.
Fix by extracting the chip_data associated with the VMD's interrupt domain.

Commit 528589947c180 ("nvmet: initialize discovery subsys after debugfs
is initialized") changed nvmet_init() to initialize nvme discovery after
"nvmet" debugfs directory is initialized. The change broke nvmet_exit()
because discovery subsystem now depends on debugfs. Debugfs should be
destroyed after discovery subsystem. Fix nvmet_exit() to do that.

The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

Since KFD proc content was moved to kernel debugfs, we can't destroy KFD
debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior
to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens
when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but
kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line
debugfs_remove_recursive(entry->proc_dentry);
tries to remove /sys/kernel/debug/kfd/proc/<pid> while
/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel
NULL pointer.
