[ Upstream commit 5f491356b7149564ab22323ccce79c8d595bfd0c ]
Binutils 2.38 complains about the use of mfpmr when building
ppc6xx_defconfig:
CC arch/powerpc/kernel/pmc.o
{standard input}: Assembler messages:
{standard input}:45: Error: unrecognized opcode: `mfpmr'
{standard input}:56: Error: unrecognized opcode: `mtpmr'
This is because by default the kernel is built with -mcpu=powerpc, and
the mt/mfpmr instructions are not defined.
It can be avoided by enabling CONFIG_E300C3_CPU, but just adding that to
the defconfig will leave open the possibility of randconfig failures.
So add machine directives around the mt/mfpmr instructions to tell
binutils how to assemble them.
