Subject: [PATCH v3 0/2] mm, ksm: fix flag-dropping behavior

Hi,

This series fixes a bug in ksm_madvise described in [1/2].
As asked by David in the reply to v2, I separated the change into two
commits:
- first contains minimal fix for the bug to make it
  individually-backportable
- second makes the VM_* flag definitions consistent

v1: https://lore.kernel.org/all/20250930063921.62354-1-acsjakub@amazon.de/
v2: https://lore.kernel.org/all/20250930130023.60106-1-acsjakub@amazon.de/

Jakub Acs (2):
  mm/ksm: fix flag-dropping behavior in ksm_madvise
  mm: redefine VM_* flag constants with BIT()
