Andy/Ingo,
While running test_vsyscall_64 and fsgsbase_64 tests, I am seeing
the following errors in dmesg.
Also these tests either take forever to run or hang. I killed it after
waiting for an hour or so. Unfortunately it makes the kselftest suite
pain to run. Could you please take a look and see if we need to disable
the tests for the time being or any way to make them not painful.
These tests went into stable as well? These commits went through x86 tree
and I didn't get a chance to run the. Did you see these problems when you
ran them on your test systems. I do have KASAN enabled on mine.
