linux(4): Add a helper intended for copying timespec's from the userspace.2022-06-17T19:34:59ZDmitry Chagindchagin@FreeBSD.org2022-05-08T13:16:47Zurn:sha1:573a0f3e6830381f3bba40559e14f9c369cbfc2f
There are many places where we copyin Linux timespec from the userspace
and then convert it to the kernel timespec. To avoid code duplication
add a tiny halper for doing this.

linux(4): Prevent time_t overflows on i386.2022-06-17T19:34:59ZDmitry Chagindchagin@FreeBSD.org2022-05-08T12:39:09Zurn:sha1:34f633b6a7aa2ad953239619563c446e8da16ec0
As native i386 time_t is still 32-bit, check that the user-provided 64-bit
tv_sec value fits to the kernel time_t, return EOVERFLOW if not.

Assuming the kernel would use random data, the 64-bit Linux kernel ignores
upper 32 bits of tv_nsec of struct timespec64 for 32-bit binaries.
