This is a note to let you know that I've just added the patch titled MIPS: fix local_{add,sub}_return on MIPS64 to the 5.16-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-fix-local_-add-sub-_return-on-mips64.patch and it can be found in the queue-5.16 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1ffe93d5593c720bc9c69578a33e0538e0888dfa Author: Huang Pei <huangpei@xxxxxxxxxxx> Date: Wed Dec 15 16:44:57 2021 +0800 MIPS: fix local_{add,sub}_return on MIPS64 [ Upstream commit 277c8cb3e8ac199f075bf9576ad286687ed17173 ] Use "daddu/dsubu" for long int on MIPS64 instead of "addu/subu" Fixes: 7232311ef14c ("local_t: mips extension") Signed-off-by: Huang Pei <huangpei@xxxxxxxxxxx> Signed-off-by: Thomas Bogendoerfer <tsbogend@xxxxxxxxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/arch/mips/include/asm/local.h b/arch/mips/include/asm/local.h index ecda7295ddcd1..3fa6340903882 100644 --- a/arch/mips/include/asm/local.h +++ b/arch/mips/include/asm/local.h @@ -5,6 +5,7 @@ #include <linux/percpu.h> #include <linux/bitops.h> #include <linux/atomic.h> +#include <asm/asm.h> #include <asm/cmpxchg.h> #include <asm/compiler.h> #include <asm/war.h> @@ -39,7 +40,7 @@ static __inline__ long local_add_return(long i, local_t * l) " .set arch=r4000 \n" __SYNC(full, loongson3_war) " \n" "1:" __LL "%1, %2 # local_add_return \n" - " addu %0, %1, %3 \n" + __stringify(LONG_ADDU) " %0, %1, %3 \n" __SC "%0, %2 \n" " beqzl %0, 1b \n" " addu %0, %1, %3 \n" @@ -55,7 +56,7 @@ static __inline__ long local_add_return(long i, local_t * l) " .set "MIPS_ISA_ARCH_LEVEL" \n" __SYNC(full, loongson3_war) " \n" "1:" __LL "%1, %2 # local_add_return \n" - " addu %0, %1, %3 \n" + __stringify(LONG_ADDU) " %0, %1, %3 \n" __SC "%0, %2 \n" " beqz %0, 1b \n" " addu %0, %1, %3 \n" @@ -88,7 +89,7 @@ static __inline__ long local_sub_return(long i, local_t * l) " .set arch=r4000 \n" __SYNC(full, loongson3_war) " \n" "1:" __LL "%1, %2 # local_sub_return \n" - " subu %0, %1, %3 \n" + __stringify(LONG_SUBU) " %0, %1, %3 \n" __SC "%0, %2 \n" " beqzl %0, 1b \n" " subu %0, %1, %3 \n" @@ -104,7 +105,7 @@ static __inline__ long local_sub_return(long i, local_t * l) " .set "MIPS_ISA_ARCH_LEVEL" \n" __SYNC(full, loongson3_war) " \n" "1:" __LL "%1, %2 # local_sub_return \n" - " subu %0, %1, %3 \n" + __stringify(LONG_SUBU) " %0, %1, %3 \n" __SC "%0, %2 \n" " beqz %0, 1b \n" " subu %0, %1, %3 \n"
