[PATCH v29 13/32] mm: Move VM_UFFD_MINOR_BIT from 37 to 38

From: Yu-cheng Yu <hidden>
Date: 2021-08-20 18:20:05
Also in: linux-api, linux-arch, linux-mm, lkml
Subsystem: memory management - core, the rest · Maintainers: Andrew Morton, David Hildenbrand, Linus Torvalds

To introduce VM_SHADOW_STACK as VM_HIGH_ARCH_BIT (37), and make all
VM_HIGH_ARCH_BITs stay together, move VM_UFFD_MINOR_BIT from 37 to 38.
