855d388df2 mmc: mediatek: add optional module reset property
This patch fixs eMMC-Access on mt7622/Bpi-64.
Before we got these Errors on mounting eMMC ion R64:
[   48.664925] blk_update_request: I/O error, dev mmcblk0, sector 204800 op 0x1:(WRITE)
flags 0x800 phys_seg 1 prio class 0
[   48.676019] Buffer I/O error on dev mmcblk0p1, logical block 0, lost sync page write

This patch adds a optional reset management for msdc.
Sometimes the bootloader does not bring msdc register
to default state, so need reset the msdc controller.

14b51ccd26 ALSA: usb-audio: Correct wrongly matching entries with audio class
The commit 51ab5d77dc ("ALSA: usb-audio: Properly match with audio
interface class") converted the quirk entries that have both vid/pid
pair and bInterface fields to match with all those with a new macro
USB_AUDIO_CLASS().  However, it turned out that those are false
conversions; all those (but the unknown KeithMcMillen device) are
actually with vendor-specific interface class, hence the conversions
broke the matching.

This patch corrects those entries to the right one,
USB_DEVICE_VENDOR_SPEC() (and USB_DEVICE() for KeithMcMillen to be
sure), and drop the unused USB_AUDIO_CLASS macro again.

Note that we also must tag rtc as disabled on am43x-epos-evm as

2152fbbd47 soc: ti: pm33xx: Simplify RTC usage to prepare to drop platform data
We must re-enable the RTC module clock enabled in RTC+DDR suspend, and
pm33xx has been using platform data callbacks for that. Looks like for
retention suspend the RTC module clock must not be re-enabled.

To remove the legacy platform data callbacks, and eventually be able to
drop the RTC legacy platform data, let's manage the RTC module clock
and register range directly in pm33xx.

2217b98262 binfmt_flat: revert "binfmt_flat: don't offset the data start"
binfmt_flat loader uses the gap between text and data to store data
segment pointers for the libraries. Even in the absence of shared
libraries it stores at least one pointer to the executable's own data
segment. Text and data can go back to back in the flat binary image and
without offsetting data segment last few instructions in the text
segment may get corrupted by the data segment pointer.

Fix it by reverting commit a2357223c5 ("binfmt_flat: don't offset the
data start").

550c2129d9 A single fix for x86 which removes the RDPID usage from the paranoid entry
path and unconditionally uses LSL to retrieve the CPU number. RDPID depends
 on MSR_TSX_AUX.  KVM has an optmization to avoid expensive MRS read/writes
 on VMENTER/EXIT. It caches the MSR values and restores them either when
 leaving the run loop, on preemption or when going out to user
 space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest
 value and before the lazy restore any exception using the paranoid entry
 will read the guest value and use it as CPU number to retrieve the GSBASE
 value for the current CPU when FSGSBASE is enabled. As RDPID is only used
 in that particular entry path, there is no reason to burden VMENTER/EXIT
 with two extra MSR writes. Remove the RDPID optimization, which is not even
 backed by numbers from the paranoid entry path instead.

fd7d6de224 io_uring: don't recurse on tsk->sighand->siglock with signalfd
If an application is doing reads on signalfd, and we arm the poll handler
because there's no data available, then the wakeup can recurse on the
tasks sighand->siglock as the signal delivery from task_work_add() will
use TWA_SIGNAL and that attempts to lock it again.

We can detect the signalfd case pretty easily by comparing the poll->head
wait_queue_head_t with the target task signalfd wait queue. Just use
normal task wakeup for this case.

f1ec7ae6c9 xhci: Always restore EP_SOFT_CLEAR_TOGGLE even if ep reset failed
Some device drivers call libusb_clear_halt when target ep queue
is not empty. (eg. spice client connected to qemu for usb redir)

Before commit f5249461b5 ("xhci: Clear the host side toggle
manually when endpoint is soft reset"), that works well.
But now, we got the error log:

    EP not empty, refuse reset

xhci_endpoint_reset failed and left ep_state's EP_SOFT_CLEAR_TOGGLE
bit still set

So all the subsequent urb sumbits to the ep will fail with the
warn log:

    Can't enqueue URB while manually clearing toggle

We need to clear ep_state EP_SOFT_CLEAR_TOGGLE bit after
xhci_endpoint_reset, even if it failed.

Sometimes re-plugging a USB device during system sleep renders the device
useless:
[  173.418345] xhci_hcd 0000:00:14.0: Get port status 2-4 read: 0x14203e2, return 0x10262

[  176.497103] usb 2-4: can't resume, status -19
[  176.497438] usb usb2-port4: logical disconnect

Because PLS equals to XDEV_RESUME, xHCI driver reports U3 to usbcore,
despite of CAS bit is flagged.

So proritize CAS over XDEV_RESUME to let usbcore handle warm-reset for
the port.

e2d977c9f1 timekeeping: Provide multi-timestamp accessor to NMI safe timekeeper
printk wants to store various timestamps (MONOTONIC, REALTIME, BOOTTIME) to
make correlation of dmesg from several systems easier.

Provide an interface to retrieve all three timestamps in one go.

There are some caveats:

1) Boot time and late sleep time injection

  Boot time is a racy access on 32bit systems if the sleep time injection
  happens late during resume and not in timekeeping_resume(). That could be
  avoided by expanding struct tk_read_base with boot offset for 32bit and
  adding more overhead to the update. As this is a hard to observe once per
  resume event which can be filtered with reasonable effort using the
  accurate mono/real timestamps, it's probably not worth the trouble.

  Aside of that it might be possible on 32 and 64 bit to observe the
  following when the sleep time injection happens late:

  CPU 0				         CPU 1
  timekeeping_resume()
  ktime_get_fast_timestamps()
    mono, real = __ktime_get_real_fast()
  					 inject_sleep_time()
  					   update boot offset
  	boot = mono + bootoffset;
  
  That means that boot time already has the sleep time adjustment, but
  real time does not. On the next readout both are in sync again.
  
  Preventing this for 64bit is not really feasible without destroying the
  careful cache layout of the timekeeper because the sequence count and
  struct tk_read_base would then need two cache lines instead of one.

2) Suspend/resume timestamps

   Access to the time keeper clock source is disabled accross the innermost
   steps of suspend/resume. The accessors still work, but the timestamps
   are frozen until time keeping is resumed which happens very early.

   For regular suspend/resume there is no observable difference vs. sched
   clock, but it might affect some of the nasty low level debug printks.

   OTOH, access to sched clock is not guaranteed accross suspend/resume on
   all systems either so it depends on the hardware in use.

   If that turns out to be a real problem then this could be mitigated by
   using sched clock in a similar way as during early boot. But it's not as
   trivial as on early boot because it needs some careful protection
   against the clock monotonic timestamp jumping backwards on resume.

71419b30ca timekeeping: Utilize local_clock() for NMI safe timekeeper during early boot
During early boot the NMI safe timekeeper returns 0 until the first
clocksource becomes available.

This prevents it from being used for printk or other facilities which today
use sched clock. sched clock can be available way before timekeeping is
initialized.

The obvious workaround for this is to utilize the early sched clock in the
default dummy clock read function until a clocksource becomes available.

After switching to the clocksource clock MONOTONIC and BOOTTIME will not
jump because the timekeeping_init() bases clock MONOTONIC on sched clock
and the offset between clock MONOTONIC and BOOTTIME is zero during boot.

Clock REALTIME cannot provide useful timestamps during early boot up to
the point where a persistent clock becomes available, which is either in
timekeeping_init() or later when the RTC driver which might depend on I2C
or other subsystems is initialized.

There is a minor difference to sched_clock() vs. suspend/resume. As the
timekeeper clock source might not be accessible during suspend, after
timekeeping_suspend() timestamps freeze up to the point where
timekeeping_resume() is invoked. OTOH this is true for some sched clock
implementations as well.

acd46a6b6d ALSA: firewire-digi00x: exclude Avid Adrenaline from detection
Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to.
However, as long as he investigated, the design of this model is hardly
similar to the one of Digi 00x family. It's better to exclude the model
from modalias of ALSA firewire-digi00x driver.

This commit changes device entries so that the model is excluded.

0bd8bce897 ALSA; firewire-tascam: exclude Tascam FE-8 from detection
Tascam FE-8 is known to support communication by asynchronous transaction
only. The support can be implemented in userspace application and
snd-firewire-ctl-services project has the support. However, ALSA
firewire-tascam driver is bound to the model.

This commit changes device entries so that the model is excluded. In a
commit 53b3ffee78 ("ALSA: firewire-tascam: change device probing
processing"), I addressed to the concern that version field in
configuration differs depending on installed firmware. However, as long
as I checked, the version number is fixed. It's safe to return version
number back to modalias.
