Module Name: src
Committed By: dsl
Date: Tue Feb 18 18:39:11 UTC 2014
Modified Files:
src/sys/arch/x86/include: cpu_extended_state.h
Added Files:
src/sys/arch/amd64/include: fpu.h
Log Message:
It seems that firefox includes machine/fpu.h on amd64.
Add the file back so that the firwfox source doesn't have to depend
on the version of netbsd it is being compiled for.
(The i386 version doesn't play the same games in its SIGFPE handler.)
