This is my second attempt to convert subsystem-wide code in v4l
for y2038 changes, removing uses of time_t in common files
and adding support for user space that defines time_t as 64 bit.
Based on the initial feedback from Hans Verkuil, I've changed the
ioctl handling to remain 100% compatible with existing headers,
which also makes it more likely that existing source code can
compile without changes.
This comes at a noticeable expense of adding complexity to
the v4l2-ioctl.c file, as we now have to handle two versions
of each ioctl command that passes a time_t in its arguments.
I have not added support for the new binary layout of v4l2_timeval
to v4l2-compat-ioctl32 yet, that is something I can do when the
basic approach has been agreed on.

Arnd Bergmann (9):
[media] dvb: use ktime_t for internal timeout
[media] dvb: remove unused systime() function
[media] dvb: don't use 'time_t' in event ioctl
[media] exynos4-is: use monotonic timestamps as advertized
[media] make VIDIOC_DQEVENT work with 64-bit time_t
[media] use v4l2_get_timestamp where possible
[media] v4l2: introduce v4l2_timeval
[media] handle 64-bit time_t in v4l2_buffer
[media] omap3isp: support 64-bit version of omap3isp_stat_data
