From 6102c005a71b4a7a6433d43b887662fb0780746d Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Thu, 4 May 2017 20:41:12 +1000 Subject: powerpc/64s: Fix unnecessary machine check handler relocation branch Similarly to commit 2563a70c3b ("powerpc/64s: Remove unnecessary relocation branch from idle handler"), the machine check handler has a BRANCH_TO from relocated to relocated code, which is unnecessary. It has also caused build errors with some toolchains: arch/powerpc/kernel/exceptions-64s.S: Assembler messages: arch/powerpc/kernel/exceptions-64s.S:395: Error: operand out of range (0xffffffffffff8280 is not between 0x0000000000000000 and 0x000000000000ffff) Fixes: 1945bc4549e5 ("powerpc/64s: Fix POWER9 machine check handler from stop state") Signed-off-by: Nicholas Piggin Reported-and-tested-by : Abdul Haleem Signed-off-by: Michael Ellerman --- arch/powerpc/kernel/exceptions-64s.S | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'arch/powerpc/kernel') diff --git a/arch/powerpc/kernel/exceptions-64s.S b/arch/powerpc/kernel/exceptions-64s.S index 3840a7700285..ef72065f684c 100644 --- a/arch/powerpc/kernel/exceptions-64s.S +++ b/arch/powerpc/kernel/exceptions-64s.S @@ -391,9 +391,7 @@ EXC_COMMON_BEGIN(machine_check_handle_early) */ BEGIN_FTR_SECTION rlwinm. r11,r12,47-31,30,31 - beq- 4f - BRANCH_TO_COMMON(r10, machine_check_idle_common) -4: + bne machine_check_idle_common END_FTR_SECTION_IFSET(CPU_FTR_HVMODE | CPU_FTR_ARCH_206) #endif -- cgit
