  "message": "[PATCH] i386: Convert i386 PDA code to use %fs\n\nConvert the PDA code to use %fs rather than %gs as the segment for\nper-processor data.  This is because some processors show a small but\nmeasurable performance gain for reloading a NULL segment selector (as %fs\ngenerally is in user-space) versus a non-NULL one (as %gs generally is).\n\nOn modern processors the difference is very small, perhaps undetectable.\nSome old AMD \"K6 3D+\" processors are noticably slower when %fs is used\nrather than %gs; I have no idea why this might be, but I think they\u0027re\nsufficiently rare that it doesn\u0027t matter much.\n\nThis patch also fixes the math emulator, which had not been adjusted to\nmatch the changed struct pt_regs.\n\n[frederik.deweerdt@gmail.com: fixit with gdb]\n[mingo@elte.hu: Fix KVM too]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Ian Campbell \u003cIan.Campbell@XenSource.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nSigned-off-by: Frederik Deweerdt \u003cfrederik.deweerdt@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\n",
