sched: fix gcc warnings
Meelis Roos reported these warnings on sparc64: CC kernel/sched.o In file included from kernel/sched.c:879: kernel/sched_debug.c: In function 'nsec_high': kernel/sched_debug.c:38: warning: comparison of distinct pointer types lacks a cast the debug check in do_div() is over-eager here, because the long long is always positive in these places. Mark this by casting them to unsigned long long. no change in code output: text data bss dec hex filename 51471 6582 376 58429 e43d sched.o.before 51471 6582 376 58429 e43d sched.o.after md5: 7f7729c111f185bf3ccea4d542abc049 sched.o.before.asm 7f7729c111f185bf3ccea4d542abc049 sched.o.after.asm Signed-off-by: Ingo Molnar <mingo@elte.hu>
