Fix this by only checking that we're greater, alternatively, we could have compared to (__NR_Linux_syscalls - 1) Signed-off-by: Kyle McMartin --- diff --git a/arch/parisc/kernel/syscall.S b/arch/parisc/kernel/syscall.S index 91b2a48b19..56f6231cb8 100644 --- a/arch/parisc/kernel/syscall.S +++ b/arch/parisc/kernel/syscall.S @@ -198,7 +198,7 @@ linux_gateway_entry: ldil L%sys_call_table, %r1 ldo R%sys_call_table(%r1), %r19 #endif - comiclr,>>= __NR_Linux_syscalls, %r20, %r0 + comiclr,>> __NR_Linux_syscalls, %r20, %r0 b,n .Lsyscall_nosys LDREGX %r20(%r19), %r19
