Subject: [git pull] misc uaccess stuff

	uaccess patches that really didn't fit anywhere else.
kvm_hv_set_msr() patch left as-is; __put_user() is by no means
final there, but that'll be dealt with along with other KVM
uaccess stuff next cycle.

The following changes since commit b44f687386875b714dae2afa768e73401e45c21c:

  drm/i915/gem: Replace user_access_begin by user_write_access_begin (2020-05-01 12:35:22 +1000)

      binfmt_elf_fdpic: don't use __... uaccess primitives
      binfmt_flat: don't use __put_user()
      x86: switch cp_stat64() to unsafe_put_user()
      TEST_ACCESS_OK _never_ had been checked anywhere
      user_regset_copyout_zero(): use clear_user()
      x86: kvm_hv_set_msr(): use __put_user() instead of 32bit __clear_user()
