Linus,

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-urgent-for-linus

up to: f18ddc13af98: alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP

A single fix to prevent the alarm timer code from returning ENOTSUPP to
user space. ENOTSUPP is a purely kernel internal error code related to
NFSv3 and should never be handed back to user space. The risk for ABI
breakage is low as the number of systems which do not have a working RTC is
very limited.

Thanks,

tglx
