	Base of uaccess pile - series from Christophe Leroy adding
user_{read,write}_access_begin().  Sat in ppc tree all along,
in vfs.git it's #uaccess.base.  No changes since the last time
it got posted, repeated for reference, based at v5.7-rc1

Christophe Leroy (3):
      uaccess: Add user_read_access_begin/end and user_write_access_begin/end
      uaccess: Selectively open read or write user access
      drm/i915/gem: Replace user_access_begin by user_write_access_begin
