Subject: [PATCH 0/3 5.2-stable] Sync mappings in vmalloc/ioremap areas

From: Joerg Roedel <jroedel@...e.de>

Backport commits from upstream to fix a data corruption
issue that gets exposed when using PTI on x86-32.

Please consider them for inclusion into stable-5.2.

Joerg Roedel (3):
  x86/mm: Check for pfn instead of page in vmalloc_sync_one()
  x86/mm: Sync also unmappings in vmalloc_sync_all()
  mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy()
