[PATCH 3.16 040/366] powerpc/lib: Fix feature fixup test of external branch

From: Ben Hutchings
Date: Sun Nov 11 2018 - 15:20:13 EST


3.16.61-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>

commit 32810d91325ec76b8ef4df463f8a0e9baf353322 upstream.

The expected case for this test was wrong, the source of the alternate
code sequence is:

FTR_SECTION_ELSE
2: or 2,2,2
PPC_LCMPI r3,1
beq 3f
blt 2b
b 3f
b 1b
ALT_FTR_SECTION_END(0, 1)
3: or 1,1,1
or 2,2,2
4: or 3,3,3

So when it's patched the '3' label should still be on the 'or 1,1,1',
and the 4 label is irrelevant and can be removed.
