<pre>The PowerPC integrated assembler seems to be missing support for the following
instructions..
mtsr, mfsr
mtdbatu, mtdbatl
mtibatu, mtibatl
.e.g.
../../../../arch/macppc/macppc/ofwreal.S:237:2: error: unrecognized instruction
mnemonic
mtibatl 2,%r4
^
../../../../arch/macppc/macppc/ofwreal.S:239:2: error: unrecognized instruction
mnemonic
mtibatu 2,%r4
^
./../../../arch/macppc/macppc/ofwreal.S:245:2: error: unrecognized instruction
mnemonic
mtdbatl 0,%r4
^
../../../../arch/macppc/macppc/ofwreal.S:247:2: error: unrecognized instruction
mnemonic
mtdbatu 0,%r4
^
../../../../arch/powerpc/powerpc/pmap.c:1817:16: error: unrecognized
instruction mnemonic
asm volatile ("mfsr %0,%1"
^
<inline asm>:1:2: note: instantiated into assembly here
mfsr 3,13
^
../../../../arch/powerpc/powerpc/pmap.c:1819:16: error: unrecognized
instruction mnemonic
asm volatile ("isync; mtsr %0,%1; isync"
^
<inline asm>:1:9: note: instantiated into assembly here
isync; mtsr 13,4; isync
