[merged mm-stable] loongarch-mm-stop-using-pte_error.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: loongarch/mm: stop using pte_ERROR()
has been removed from the -mm tree.  Its filename was
     loongarch-mm-stop-using-pte_error.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: loongarch/mm: stop using pte_ERROR()
Date: Mon, 31 Aug 2026 11:13:25 +0530

Directly use pr_err() in __set_fixmap() and drop pte_ERROR() which helps
in eventually dropping pte_ERROR() macro across the tree.  In this new
printing __FILE__ and __LINE__ has been dropped because they are always
the same and don't really add any value.  The new ptval_to_str() helper is
being used for converting pgtable entry value into a string.  The error
message itself has been cleaned up as well.
