Subject: [GIT PULL] usercopy for v5.4-rc4

Hi Linus,

/* Summary */
This contains two improvements for the copy_struct_from_user() tests:
- The first patch is a coding style change to get rid of the ugly
  if ((ret |= test())) you pointed out when you pulled the original patchset.
- The second patch avoids soft lockups when running the usercopy tests on
  machines with large page sizes by scanning only a 1024 byte region.

The following changes since commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce:

  Linux 5.4-rc2 (2019-10-06 14:27:30 -0700)
