Subject: [PATCH 0/9] x86/fpu: remove lazy FPU mode & various FPU cleanups
Date: Tue, 4 Oct 2016 20:34:29 -0400 [thread overview]
Message-ID: <1475627678-20788-1-git-send-email-riel@redhat.com> (raw)
This series removes lazy FPU mode, and cleans up various bits
and pieces around the FPU code.
I have run this through a basic floating point test that involves
about 1.5 billion context switches and 45 minutes of swapping at
250MB/second.
This seems to tease out bugs fairly well, though I would not mind
an actual floating point test suite...
