Multiple CephFS mounts on a host is increasingly common so
disambiguating messages like this is necessary and will make it easier
to debug issues.

At the same this will improve the debug logs to make them easier to
troubleshooting issues, such as print the ino# instead only printing
the memory addresses of the corresponding inodes and print the dentry
names instead of the corresponding memory addresses for the dentry,etc.

    sysvec_apic_timer_interrupt+0x6e/0x90

The reason is the recent conversion of the TSC synchronization function
during CPU hotplug on the control CPU to a SMP function call. In case
that the synchronization with the upcoming CPU fails, the TSC has to be
marked unstable via clocksource_mark_unstable().

clocksource_mark_unstable() acquires 'watchdog_lock', but that lock is
taken with interrupts enabled in the watchdog timer callback to minimize
interrupt disabled time. That's obviously a possible deadlock scenario,

Before that change the synchronization function was invoked in thread
context so this could not happen.

As it is not crucical whether the unstable marking happens slightly
delayed, defer the call to a worker thread which avoids the lock context
problem.

David and a few others reported that on certain newer systems some legacy
interrupts fail to work correctly.

Debugging revealed that the BIOS of these systems leaves the legacy PIC in
uninitialized state which makes the PIC detection fail and the kernel
switches to a dummy implementation.

Unfortunately this fallback causes quite some code to fail as it depends on
checks for the number of legacy PIC interrupts or the availability of the
real PIC.

In theory there is no reason to use the PIC on any modern system when
IO/APIC is available, but the dependencies on the related checks cannot be
resolved trivially and on short notice. This needs lots of analysis and
rework.

The PIC detection has been added to avoid quirky checks and force selection
of the dummy implementation all over the place, especially in VM guest
scenarios. So it's not an option to revert the relevant commit as that
would break a lot of other scenarios.

One solution would be to try to initialize the PIC on detection fail and
retry the detection, but that puts the burden on everything which does not
have a PIC.

Fortunately the ACPI/MADT table header has a flag field, which advertises
in bit 0 that the system is PCAT compatible, which means it has a legacy
8259 PIC.

Evaluate that bit and if set avoid the detection routine and keep the real
PIC installed, which then gets initialized (for nothing) and makes the rest
of the code with all the dependencies work again.

Commit aa3998db ("ata: libata-scsi: Disable scsi device
manage_system_start_stop") change setting the manage_system_start_stop
flag to false for libata managed disks to enable libata internal
management of disk suspend/resume. However, a side effect of this change
is that on system shutdown, disks are no longer being stopped (set to
standby mode with the heads unloaded). While this is not a critical
issue, this unclean shutdown is not recommended and shows up with
increased smart counters (e.g. the unexpected power loss counter
"Unexpect_Power_Loss_Ct").

Instead of defining a shutdown driver method for all ATA adapter
drivers (not all of them define that operation), this patch resolves
this issue by further refining the sd driver start/stop control of disks
using the new flag manage_shutdown. If this new flag is set to true by
a low level driver, the function sd_shutdown() will issue a
START STOP UNIT command with the start argument set to 0 when a disk
needs to be powered off (suspended) on system power off, that is, when
system_state is equal to SYSTEM_POWER_OFF.

Similarly to the other manage_xxx flags, the new manage_shutdown flag is
exposed through sysfs as a read-write device attribute.

To avoid any confusion between manage_shutdown and
manage_system_start_stop, the comments describing these flags in
include/scsi/scsi.h are also improved.

 "A couple of platforms have some last-minute fixes, in particular:

   - riscv gets some fixes for noncoherent DMA on the renesas and thead
     platforms and dts fix for SPI on the visionfive 2 board

   - Qualcomm Snapdragon gets three dts fixes to address board specific
     regressions on the pmic and gpio nodes

   - Rockchip platforms get multiple dts fixes to address issues on the
     recent rk3399 platform as well as the older rk3128 platform that
     apparently regressed a while ago.

   - TI OMAP gets some trivial code and dts fixes and a regression fix
     for the omap1 ams-delta modem

   - NXP i.MX firmware has one fix for a use-after-free but in its error
     handling"

Pull networking fixes from Paolo Abeni:
 "Including fixes from WiFi and netfilter.

  Most regressions addressed here come from quite old versions, with the
  exceptions of the iavf one and the WiFi fixes. No known outstanding
  reports or investigation.

  Fixes to fixes:

   - eth: iavf: in iavf_down, disable queues when removing the driver

  Previous releases - regressions:

   - sched: act_ct: additional checks for outdated flows

   - tcp: do not leave an empty skb in write queue

   - tcp: fix wrong RTO timeout when received SACK reneging

   - wifi: cfg80211: pass correct pointer to rdev_inform_bss()

   - eth: i40e: sync next_to_clean and next_to_process for programming
     status desc

   - eth: iavf: initialize waitqueues before starting watchdog_task

  Previous releases - always broken:

   - eth: r8169: fix data-races

   - eth: igb: fix potential memory leak in igb_add_ethtool_nfc_entry

   - eth: r8152: avoid writing garbage to the adapter's registers

   - eth: gtp: fix fragmentation needed check with gso"
