Subject: [PATCH 0/3] Fixes for usercopy

Kees, I'm hoping you'll take these through your tree.  I think they're
all reasonable fixes to go into 5.19.  The first one is essential;
it fixes two different bugs that people have hit.

Matthew Wilcox (Oracle) (3):
  usercopy: Handle vm_map_ram() areas
  usercopy: Cast pointer to an integer once
  usercopy: Make usercopy resilient against ridiculously large copies
