For BE architectures there is one significant difference
in comparison with time64 support for little-endian
architectures like ARMv7.
The difference is that we strictly need to pass two 64bit
values to system calls because Linux Kernel internally uses
`struct __kernel_timespec` and similar, which consists of two
64bit fields.
For this reason many files have been changed to convert
pointers to timespec-family structures (mixed of 64bit and 32bit values)
to the pointer of the similar but 64bit-only structures
for using as system calls args.
This is general prerequisite for any BE architecture.

This doesn't look like a reserved name, so I'm not sure you can
use this name in the time.h. Also I think that checking whether
__ts is NULL is better done inside this macro.

This is missing the 'timespec is non-NULL' check.

__ts looks good to me, it's the TO_TS64_P and TO_ITS64_P
that don't look right. They are not a part of the libc interface,
so I'd say they just shouldn't be in that header, but in some other,
internal-use-only header instead. If there's no other place for them
they should have at least the leading underscore.

Okay, I will move these marcoses to some internal header

If you find such place then I guess struct __ts64_struct and struct
__its64_struct
can go there as well as they're only used internally.
