The asm to read and write EFLAGS from userspace is horrible. The compiler builtins are now available on all supported compilers, so use them instead. (The compiler builtins are also unnecessarily ugly, but that's a more manageable level of ugliness.)

Several of the x86 selftests end up with executable stacks because the asm was missing the annotation that says that they are modern and don't need executable stacks. Add the annotations.

Setting GS to 1, 2, or 3 causes a nonsensical part of the IRET microcode to change GS back to zero on a return from kernel mode to user mode. The result is that these tests fail randomly depending on when interrupts happen. Detect when this happens and let the test pass.

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 mm: fix pin vs. gup mismatch with gate pages
The existing code accepted process_vm_readv() success or failure as long as it didn't return garbage. This is too weak: if the vsyscall page is readable, then process_vm_readv() should succeed and, if the page is not readable, then it should fail.
