Yet, in arch/um/include/process.h, we see, unchanged since the year dot, the
obviously wrong prototype:

extern void alarm_handler(int sig, struct sigcontext sc);

Hence:

  CC      arch/um/os-Linux/time.o
arch/um/os-Linux/time.c: In function ‘deliver_alarm’:
arch/um/os-Linux/time.c:119: error: incompatible type for argument 2 of ‘alarm_handler’
make[1]: *** [arch/um/os-Linux/time.o] Error 1
make: *** [arch/um/os-Linux] Error 2

Fix trivial:
