[PATCH 0/2] Make HWPoison helpers config-independent

[Kaitao Cheng <kaitao.cheng@linux.dev>]

Make the HWPoison page flag's test-and-set and test-and-clear accessors
available regardless of CONFIG_MEMORY_FAILURE. When memory failure handling
is disabled, the accessors return false, matching the absence of HWPoison
state and providing a consistent interface across configurations.

Use the config-independent interface in the pmem driver to remove its
private test_and_clear_pmem_poison() wrapper and the associated header
dependency. No functional change is intended.

Kaitao Cheng (2):
  mm/page-flags: Define HWPoison test-and-change helpers unconditionally
  nvdimm/pmem: Remove test_and_clear_pmem_poison()
