Subject: [PATCH v3 0/4] cxl: Handle background commands

Hi,

This is the latest iteration of the synchronous background command handling
work. Currently there are no users, but it is expected that firmware update
and scan media be the first two to use it.

Patches 1-3 are requirements for the actual patch 4.

Changes from v1/v2 (https://lore.kernel.org/linux-cxl/20230502171841.21317-1-dave@stgolabs.net):
    o Picked up tags for patches 1 and 2.
    o Added more context to the changelog in the rcuwait patch 1. (Dan)
    o Added new patch 3 for common request irq functionality. (Dan)
    o Misc cleanups in patch 4. (Jonathan)
    o Don't clobber the ctrl settings. (Dan)
    o Removed bogus warning in irq handler. (Jonathan, Dan)
    o Make sleep uninterruptible and clarify in the changelog that
      timeouts are in fact unexpected.
    
Applies against 'fixes' from cxl.git.

Thanks!

Davidlohr Bueso (4):
  rcuwait: Support timeouts
  cxl/pci: Allocate irq vectors earlier during probe
  cxl/pci: Introduce cxl_request_irq()
  cxl/mbox: Add background cmd handling machinery
