[PATCH v4 0/4] cxl: Dirty shutdown followups

[Davidlohr Bueso <dave@stgolabs.net>]

Changes from v3 (https://lore.kernel.org/linux-cxl/20250219062832.237881-1-dave@stgolabs.net/):
  - pickup reviews
  - simplify patch 1 (DaveJ)
  - change -1 to ULLONG_MAX in patch 3 (Ira)
  - patch 4 replace int for u8 for shutdown state (DaveJ)

Hi,

Some followup patches to the GPF work. First two patches are from feedback
provided by DaveJ. The third patch adds a $platform/dirty_shutdown sysfs
attribute to expose the count to userspace. Fourth patch adds support
emulating the set shutdown state command for the mock device.

Applies against the -next branch of cxl.git.

Thanks!
