[failures] mm-drop-unused-set_pte_safe.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: drop unused set_pte_safe()
has been removed from the -mm tree.  Its filename was
     mm-drop-unused-set_pte_safe.patch

This patch was dropped because it had testing failures

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm: drop unused set_pte_safe()
Date: Tue, 10 Sep 2024 15:40:26 +0530

All set_pte_safe() usage have been dropped after the commit eccd906484d1
("x86/mm: Do not use set_{pud, pmd}_safe() when splitting a large page")
This just drops now unused helper set_pte_safe().

Besides this macro was buggy due to doing direct dereferencing of the pte,
and if it were to be kept, it should have been updated to use a single
call to ptep_get().
