of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: parisc/mm: directly use generic [pmd|pgd]_clear_bad()
Date: Mon, 31 Aug 2026 11:13:26 +0530

Drop [pmd|pgd]_ERROR() followed by [pmd|pgd]_clear() instances.  But
instead directly use semantically equivalent generic helpers
[pmd|pgd]_clear_bad() in unmap_uncached_[pte|pmd]() which helps in
dropping their corresponding [pmd|pgd]_ERROR() macros across the tree.
