Currently <linux/compiler.h> isn't included at all (not even transitively) in <asm/ptrace.h>. arch/parisc/kernel/asm-offsets.c just happens to include the following chain of includes before <asm/ptrace.h>: <linux/sched.h> -> <asm/processor.h> -> <asm/hardware.h> -> <linux/mod_devicetable.h> -> <linux/uuid.h> -> <linux/string.h> -> <linux/compiler.h> . That chain will be broken, because in one of the next commits <asm/hardware.h> is changed to only include <linux/device-id/parisc.h> instead of <linux/mod_devicetable.h>. So to ensure arch/parisc/kernel/asm-offsets.c knows about unlikely() even after that change, #include <linux/compiler.h> explicitly.
