When mounting fsdax pmem device, commit 6180bb44 ("dax: fix
detection of dax support for non-persistent memory block devices")
introduces the stack overflow [1][2]. Here is the call path for
mounting ext4 file system:
  ext4_fill_super
    bdev_dax_supported
      __bdev_dax_supported
        dax_supported
          generic_fsdax_supported
            __generic_fsdax_supported
              bdev_dax_supported

The call path leads to the infinite calling loop, so we cannot
call bdev_dax_supported() in __generic_fsdax_supported(). The sanity
checking of the variable 'dax_dev' is moved prior to the two
bdev_dax_pgoff() checks [3][4].

DM was calling generic_fsdax_supported() to determine whether a device
referenced in the DM table supports DAX. However this is a helper for "leaf" device drivers so that
they don't have to duplicate common generic checks. High level code
should call dax_supported() helper which that calls into appropriate
helper for the particular device. This problem manifested itself as
kernel messages:

dm-3: error: dax access failed (-95)

when lvm2-testsuite run in cases where a DM device was stacked on top of
another DM device.

controllers with XHCI_AVOID_BEI quirk cause too frequent interrupts
and affect power management.

To avoid interrupting on every isochronous interval the BEI (Block
Event Interrupt) flag is set for all except the last Isoch TRB in a URB.
This lead to event ring filling up in case several isoc URB were
queued and cancelled rapidly, which some controllers didn't
handle well, and thus the XHCI_AVOID_BEI quirk was introduced.
see commit 227a4fd8

 ("usb: xhci: apply XHCI_AVOID_BEI quirk to all
Intel xHCI controllers")

With the XHCI_AVOID_BEI quirk each Isoch TRB will trigger an interrupt.
This can cause up to 8000 interrupts per second for isochronous transfers
with HD USB3 cameras, affecting power saving.

The event ring fits 256 events, instead of interrupting on every
isochronous TRB if XHCI_AVOID_BEI is set we make sure at least every
8th Isochronous TRB asserts an interrupt, clearing the event ring.

If the xhci-plat.c is the platform driver, after the runtime pm is
enabled, the xhci_suspend is called if nothing is connected on
the port. When the system goes to suspend, it will call xhci_suspend again
if USB wakeup is enabled.

Since the runtime suspend wakeup setting is not always the same as
system suspend wakeup setting, eg, at runtime suspend we always need
wakeup if the controller is in low power mode; but at system suspend,
we may not need wakeup. So, we move the judgement after changing
wakeup setting.
