+# ChangeSet
+
+#   We need to clear all exceptions before synchronizing
+#   with the FPU, since we aren't ready to handle a FP
+#   exception here and we're getting rid of all FP state.
+
+#   Special thanks to Alexander Nyberg for reports and
+#   testing. Alternate patches by Sergey Vlasov and Andi
+#   Kleen, who both worked on this.

+#   Signed-off-by: Linus Torvalds <torvalds@osdl.org>
