Hi,
with CONFIG_HZ_300=y I see these warnings :
...
kernel/time.c: In function 'msecs_to_jiffies':
kernel/time.c:472: warning: integer constant is too large for 'long' type
kernel/time.c: In function 'usecs_to_jiffies':
kernel/time.c:487: warning: integer constant is too large for 'long' type
...
I think this was introduced by :
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=bdc807...
If you need more infos let me know.
Regards,
Gabriel
