Normally people write - "cmpw" or "cmpd" for the second cmp operand 0 or 1. But, frequently - people forget, and write "cmp" with just three operands. - - With older binutils this is silently accepted as if this was "cmpw", - while often "cmpd" is wanted. With newer binutils GAS will complain - about this for 64-bit code. For 32-bit code it still silently assumes - "cmpw" is what is meant. - -In this case, cmpwi is called for, so this is just a build fix for -new toolchains. - -Cc: stable@vger.kernel.org # v3.0+ -Signed-off-by: Nicholas Piggin <npiggin@gmail.com> -Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> ---- - arch/powerpc/kernel/head_64.S | 8 ++++---- - 1 file changed, 4 insertions(+), 4 deletions(-) - -diff --git a/arch/powerpc/kernel/head_64.S b/arch/powerpc/kernel/head_64.S -index 451a8e1..bdb4612 100644 ---- a/arch/powerpc/kernel/head_64.S -+++ b/arch/powerpc/kernel/head_64.S -@@ -221,9 +221,9 @@ booting_thread_hwid: - */ - _GLOBAL(book3e_start_thread) - LOAD_REG_IMMEDIATE(r5, MSR_KERNEL) -- cmpi 0, r3, 0 -+ cmpwi r3, 0 - beq 10f -- cmpi 0, r3, 1 -+ cmpwi r3, 1 - beq 11f - /* If the thread id is invalid, just exit. */ - b 13f -@@ -248,9 +248,9 @@ _GLOBAL(book3e_start_thread) - * r3 = the thread physical id - */ - _GLOBAL(book3e_stop_thread) -- cmpi 0, r3, 0 -+ cmpwi r3, 0 - beq 10f -- cmpi 0, r3, 1 -+ cmpwi r3, 1 - beq 10f - /* If the thread id is invalid, just exit. */ - b 13f --- -2.7.4 - |
