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().
