Didn't apply to perf/urgent:

[acme@jouet linux]$ patch -p1 < /wb/1.patch

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|--- a/include/linux/sched/clock.h
|+++ b/include/linux/sched/clock.h
--------------------------
File to patch: ^C
[acme@jouet linux]$
[acme@jouet linux]$

Trying with perf/core...
