When the computer enters sleep status without a monitor
connected, the system switches the console to the virtual
terminal tty63(SUSPEND_CONSOLE).
If a monitor is subsequently connected before waking up,
the system skips the required VT restoration process
during wake-up, leaving the console on tty63 instead of
switching back to tty1.
To fix this issue, a global flag vt_switch_done is introduced
to record whether the system has successfully switched to
the suspend console via vt_move_to_console() during suspend.
If the switch was completed, vt_switch_done is set to 1.
Later during resume, this flag is checked to ensure that
the original console is restored properly by calling
vt_move_to_console(orig_fgconsole, 0).
This prevents scenarios where the resume logic skips console
restoration due to incorrect detection of the console state,
especially when a monitor is reconnected before waking up.

====================
ptp: Provide support for auxiliary clocks for PTP_SYS_OFFSET_EXTENDED
This is a follow up to the V1 series, which can be found here:
https://lore.kernel.org/all/20250626124327.667087805@linutronix.de
to address the merge logistics problem, which I created myself.
Changes vs. V1:
- Make patch 1, which provides the timestamping function temporarily
define CLOCK_AUX* if undefined so that it can be merged independently,
- Add a missing check for CONFIG_POSIX_AUX_CLOCK in the PTP IOCTL
- Picked up tags
Merge logistics if agreed on:
1) Patch #1 is applied to the tip tree on top of plain v6.16-rc1 and
tagged
2) That tag is merged into tip:timers/ptp and the temporary CLOCK_AUX
define is removed in a subsequent commit
3) Network folks merge the tag and apply patches #2 + #3
So the only fallout from this are the extra merges in both trees and the
cleanup commit in the tip tree. But that way there are no dependencies and
no duplicate commits with different SHAs.
Thoughts?
Due to the above constraints there is no branch offered to pull from right
now. Sorry for the inconveniance. Should have thought about that earlier.

Allow ioctl(PTP_SYS_OFFSET_EXTENDED*) to select CLOCK_AUX clock ids for
generating the pre and post hardware readout timestamps.
Aside of adding these clocks to the clock ID validation, this also requires
to check the timestamp to be valid, i.e. the seconds value being greater
than or equal zero. This is necessary because AUX clocks can be
asynchronously enabled or disabled, so there is no way to validate the
availability upfront.
The same could have been achieved by handing the return value of
ktime_get_aux_ts64() all the way down to the IOCTL call site, but that'd
require to modify all existing ptp::gettimex64() callbacks and their inner
call chains. The timestamp check achieves the same with less churn and less
complicated code all over the place.

The inlined ptp_read_system_[pre|post]ts() switch cases expand to a copious
amount of text in drivers, e.g. ~500 bytes in e1000e. Adding auxiliary
clock support to the inlines would increase it further.
Replace the inline switch case with a call to ktime_get_clock_ts64(), which
reduces the code size in drivers and allows to access auxiliary clocks once
they are enabled in the IOCTL parameter filter.
No functional change.

tray is used for both SD and SIM cards. If the SD card is placed
at the outermost location in the tray, the SIM card may come in
contact with SD card power-supply while removing the tray, possibly
resulting in SIM damage.
To prevent that, make sure the SD card is really inserted by reading
the Card Detect pin state. If it's not, turn off the power in
sdhci_msm_check_power_status() and also set the BUS_FAIL power state
on the controller as part of pwr_irq handling for BUS_ON request.

The timer which ensures that no more than 3 LACPDUs are transmitted in
a second rearms itself every 333ms regardless of whether an LACPDU is
transmitted when the timer expires. This causes LACPDU tx to be delayed
until the next expiration of the timer, which effectively aligns LACPDUs
to ~333ms boundaries. This results in a variable amount of jitter in the
timing of periodic LACPDUs.
Change this to only rearm the timer when an LACPDU is actually sent,
allowing tx at any point after the timer has expired.

Merge tag 'ktime-get-clock-ts64-for-ptp' into timers/ptp
Pull the base implementation of ktime_get_clock_ts64() for PTP, which
contains a temporary CLOCK_AUX* workaround. That was created to allow
integration of depending changes into the networking tree. The workaround
is going to be removed in a subsequent change in the timekeeping tree.
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
PTP implements an inline switch case for taking timestamps from various
POSIX clock IDs, which already consumes quite some text space. Expanding it
for auxiliary clocks really becomes too big for inlining.
Provide a out of line version.
The function invalidates the timestamp in case the clock is invalid. The
invalidation allows to implement a validation check without the need to
propagate a return value through deep existing call chains.
Due to merge logistics this temporarily defines CLOCK_AUX[_LAST] if
undefined, so that the plain branch, which does not contain any of the core
timekeeper changes, can be pulled into the networking tree as prerequisite
for the PTP side changes. These temporary defines are removed after that
branch is merged into the tip::timers/ptp branch. That way the result in
-next or upstream in the next merge window has zero dependencies.

Couple of fixes to address:
1. The safety and memory issues in the FF-A notification callback handler:
The fixes replaces a mutex with an rwlock to prevent sleeping in atomic
context, resolving kernel warnings. Memory allocation is moved outside
the lock to support this transition safely. Additionally, a memory leak
in the notifier unregistration path is fixed by properly freeing the
callback node.
2. The missing entry in struct ffa_indirect_msg_hdr:
The fix adds the missing 32 bit reserved entry in the structure as
required by the FF-A specification.
