[PATCH] alpha: add missing address argument in call to page_table_check_pte_clear()

From: Thomas Weißschuh

Date: Fri Feb 13 2026 - 02:41:32 EST


After the merge of the alpha and mm trees, this code does not compile,
as a parameter is missing in a call to page_table_check_pte_clear().

The parameter was re-added in commit d7b4b67eb6b3 ("mm/page_table_check:
reinstate address parameter in [__]page_table_check_pte_clear()").
The alpha-specific code was newly added in commit dd5712f3379c ("alpha:
fix user-space corruption during memory compaction").

Fixes: 4cff5c05e076 ("Merge tag 'mm-stable-2026-02-11-19-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm")

This should go directly through Linus, in my opinion.
