Well spotted, this is indeed a very recent change I did to the patch.
The idea here is to hide any use of 'time_t', 'timespec' and 'timeval'
from kernel compilation. These types are now defined in an incompatible
way by libc, so we have to remove them from the kernel's uapi headers.
I would prefer to remove them completely from the kernel (rather than
moving them from uapi to internal headers) to make it harder to write
y2038-incompatible code, and with the 90 patches I sent this week,
all users are gone from the kernel (this series was the last part).
Interestingly, hiding snd_timer_status from the drivers /also/ caught
a but in a file when I had missed a reference that needed to be converted
to snd_timer_status64.
