2015-05-08	x86, selftests: Add a test for the "sysret_ss_attrs" bug	Andy Lutomirski	1	-0/+67
	On AMD CPUs, SYSRET can return with a valid SS descriptor with with the hidden attributes set to an unusable state. Make sure the kernel doesn't let this happen. This detects an as-yet-unfixed regression. Note that the 64-bit version of this test fails on AMD CPUs on all kernel versions, although the issue in the 64-bit case is much less severe than in the 32-bit case.
