[PATCH 4.8 037/140] powerpc/xmon: Dont use ld on 32-bit
From: Greg Kroah-Hartman
Date: Wed Oct 26 2016 - 09:20:32 EST
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>
commit b42d9023a31e384504f5b53fc9a437d5536a3f63 upstream.
In commit 31cdd0c39c75 ("powerpc/xmon: Fix SPR read/write commands and
add command to dump SPRs") I added two uses of the "ld" instruction in
spr_access.S. "ld" is a 64-bit instruction, so shouldn't be used on
32-bit CPUs.
Replace it with PPC_LL which is a macro that gives us either "ld" or
"lwz" depending on whether we're 64 or 32-bit.
Fixes: 31cdd0c39c75 ("powerpc/xmon: Fix SPR read/write commands and add command to dump SPRs")
