| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: "David S. Miller" <davem@davemloft.net>
commit e0adb9902fb338a9fe634c3c2a3e474075c733ba upstream.
Newer version of binutils are more strict about specifying the correct options to enable certain classes of instructions.
The sparc32 build is done for v7 in order to support sun4c systems which lack hardware integer multiply and divide instructions.
So we have to pass -Av8 when building the assembler routines that use these instructions and get patched into the kernel when we find out that we have a v8 capable cpu.
