Merge branch 'gate-page-refcount' (patches from Dave Hansen)
Merge gate page refcount fix from Dave Hansen:
"During the conversion over to pin_user_pages(), gate pages were missed.
The fix is pretty simple, and is accompanied by a new test from Andy
which probably would have caught this earlier"
* emailed patches from Dave Hansen <dave.hansen@linux.intel.com>:
selftests/x86/test_vsyscall: Improve the process_vm_readv() test
