[Andrew Morton]

The quilt patch titled
     Subject: x86/mm: always pass NULL as the first argument of switch_mm_irqs_off()
has been removed from the -mm tree.  Its filename was
     x86-mm-always-pass-null-as-the-first-argument-of-switch_mm_irqs_off.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: x86/mm: always pass NULL as the first argument of switch_mm_irqs_off()
Date: Thu, 22 Feb 2024 19:09:11 +0000

The first argument of switch_mm_irqs_off() is unused by the x86
implementation.  Make sure that x86 code never passes a non-NULL value to
make this clear.  Update the only non violating caller, switch_mm().
