Commit 1d9d8639 ("perf,x86: fix kernel crash with PEBS/BTS after
suspend/resume") fixed a crash when doing PEBS performance profiling
after resuming, but in using init_debug_store_on_cpu() to restore the
DS_AREA mtrr it also resulted in a new WARN_ON() triggering.

init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
cross-calls to do the MSR update.  Which is not really valid at the
early resume stage, and the warning is quite reasonable.  Now, it all
happens to _work_, for the simple reason that smp_call_function_single()
ends up just doing the call directly on the CPU when the CPU number
matches, but we really should just do the wrmsr() directly instead.

This duplicates the wrmsr() logic, but hopefully we can just remove the
wrmsr_on_cpu() version eventually.

Pull btrfs fixes from Chris Mason:

  btrfs: use rcu_barrier() to wait for bdev puts at unmount
  Btrfs: remove btrfs_try_spin_lock
  Btrfs: get better concurrency for snapshot-aware defrag work

Users report that an extent map's list is still linked when it's actually
going to be freed from cache.

The story is that

a) when we're going to drop an extent map and may split this large one into
smaller ems, and if this large one is flagged as EXTENT_FLAG_LOGGING which means
that it's on the list to be logged, then the smaller ems split from it will also
be flagged as EXTENT_FLAG_LOGGING, and this is _not_ expected.

b) we'll keep ems from unlinking the list and freeing when they are flagged with
EXTENT_FLAG_LOGGING, because the log code holds one reference.

The end result is the warning, but the truth is that we set the flag
EXTENT_FLAG_LOGGING only during fsync.

So clear flag EXTENT_FLAG_LOGGING for extent maps split from a large one.

This patch fixes a kernel crash when using precise sampling (PEBS)
after a suspend/resume. Turns out the CPU notifier code is not invoked
on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly
by the kernel and keeps it power-on/resume value of 0 causing any PEBS
measurement to crash when running on CPU0.

The workaround is to add a hook in the actual resume code to restore
the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0,
the DS_AREA will be restored twice but this is harmless.

`labpc_common_detach()` calls `comedi_pci_disable()` unconditionally.
That's okay for PCI devices and harmless for ISA devices (as the
`hw_dev` member will be NULL so `comedi_to_pci_dev()` will return NULL
and `comedi_pci_disable()` checks for that), but it is disastrous for
PCMCIA devices.  Those are managed by the "ni_labpc_cs" module but it
calls this `labpc_common_detach()` and the `hw_dev` member will be
pointing to the `struct device` embedded in a `struct pcmcia_device` in
that case.  That's enough to confuse `comedi_pci_disable()` into
thinking it's a valid PCI device to be disabled.

Use the private board information (`thisboard`) to make sure it is a PCI
device before calling `comedi_pci_disable()`.

Some PCI drivers use the "spare" `iobase` member of `struct

that `comedi_pci_enable()` and `comedi_pci_disable()` use the

what needs to be done.

Add 1-bit bit-field member `ioenabled` of type `bool` to `struct
comedi_device`.  Use this to keep track of whether a PCI device and its
BARs have been successfully enabled by `comedi_pci_enable()`.  This
avoids overloading the meaning of the `iobase` member which is used by
several drivers to hold the base port I/O address of a board's "main"
registers.  Other drivers using MMIO use `iobase` as a flag to indicate
that the preceding call to `comedi_pci_enable()` was successful.  They
no longer need to do that.

The name `ioenabled` is intended to be PCI-agnostic so it can be used
for similar purposes by non-PCI drivers.

Florent Boudet reports success using a NI PXI-6624 board with a
trivially modified version of the "ni_660x" driver (addition to the PCI
device ID table and comedi board table).  He did this with the
out-of-tree Comedi drivers at www.comedi.org, but it applies equally to
the in-tree "staging" drivers.

He reports the PXI-6624 is basically the same as the PXI-6602, but with
isolated channels and external voltage source.

Add support for NI PXI-6224 to the "ni_660x" driver.

(Maybe the driver should be renamed to "ni_66xx"?)

Back in the old days (before "staging") when Comedi only supported
manual configuration of devices, the "adv_pci_dio" driver supported both
PCI-1753 ("pci1753") and PCI-1753E ("pci1753e").  In actual fact,
"pci1753e" is just a PCI-1753 connected by a ribbon cable to a PCI-1753E
expansion card, which is plugged into a PCI slot but is not a PCI device
itself.  Now that the "adv_pci_dio" driver only supports automatic
configuration of devices and the main "comedi" module no longer allows
auto-configuration to be disabled, a PCI-1753 with a PCI-1753E expansion
card is always treated as an unexpanded PCI-1753 ("pci1753") and there
is no way to override it.  (Recently, an undefined macro
`USE_PCI1753E_BOARDINFO` was used to make the driver switch to
supporting "pci1753e" instead of "pci1753", but this is less than
ideal.)

Advantech has their own Linux (non-Comedi) driver for the PCI-1753 which
detects whether the PCI-1753E expansion card is connected to the
PCI-1753 by fiddling with a register at offset 53 from the main
registers base.

Use Advantech's test in our "adv_pci_dio" driver.  If the board appears
to be a PCI-1753 ("pci1753"), check if the expansion card appears to be
present, and if so, treat the device as a PCI-1753 plus PCI-1753E
expansion card ("pci1753e").

Also, get rid of `enum dio_boardid` (`BOARD_...` enum values) which was
added recently and just use the older `TYPE_...` enum values from `enum
hw_cards_id` instead as the mapping is now 1-to-1.
