[PATCH] move rtc compat ioctl handling to fs/compat_ioctl.c
This patch implements generic handling of RTC_IRQP_READ32, RTC_IRQP_SET32,
RTC_EPOCH_READ32 and RTC_EPOCH_SET32 in fs/compat_ioctl.c. It's based on the
x86_64 code which needed a little massaging to be endian-clean.
parisc used COMPAT_IOCTL or generic w_long handlers for these whichce is wrong
and can't work because the ioctls encode sizeof(unsigned long) in their ioctl
number. parisc also duplicated COMPAT_IOCTL entries for other rtc ioctls
which I remove in this patch, too.
