Subject: [PATCH mm-unstable 0/2] mseal system mappings fix + s390 enablement

When rebasing the mseal series on top of the generic vdso data storage
the VM_SEALED_SYSMAP vm flag for the vvar mapping got lost. Add that again.

Also add s390 support for MSEAL_SYSTEM_MAPPINGS.

Heiko Carstens (2):
  mseal sysmap: generic vdso vvar mapping
  mseal sysmap: enable s390
