time: ntp: simplify the MAX_TICKADJ_SCALED definition
Impact: cleanup, no functionality changed There's an ugly u64 typecase in the MAX_TICKADJ_SCALED definition, this can be eliminated by making the MAX_TICKADJ constant's type 64-bit (signed). kernel/time/ntp.o: text data bss dec hex filename 2504 114 136 2754 ac2 ntp.o.before 2504 114 136 2754 ac2 ntp.o.after md5: 41f3009debc9b397d7394dd77d912f0a ntp.o.before.asm 41f3009debc9b397d7394dd77d912f0a ntp.o.after.asm Signed-off-by: Ingo Molnar <mingo@elte.hu>
