[folded-merged] nvdimm-pmem-remove-test_and_clear_pmem_poison.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: nvdimm/pmem: remove test_and_clear_pmem_poison()
has been removed from the -mm tree.  Its filename was
     nvdimm-pmem-remove-test_and_clear_pmem_poison.patch

This patch was dropped because it was folded into mm-page-flags-define-hwpoison-test-and-change-helpers-unconditionally.patch

Subject: nvdimm/pmem: remove test_and_clear_pmem_poison()
Date: Thu, 3 Sep 2026 13:35:35 +0800

TestClearPageHWPoison() is now defined regardless of whether
CONFIG_MEMORY_FAILURE is enabled, returning false when memory failure
handling is unavailable.

The test_and_clear_pmem_poison() wrapper duplicates this configuration
handling and has no other pmem-specific behavior.

Call TestClearPageHWPoison() directly and remove the redundant wrapper. 
This also removes the need to include page-flags.h from pmem.h.

No functional change is intended.
