This extends the x86 copy of the sysvipc data structures to deal with 32-bit user space that has 64-bit time_t and wants to see timestamps beyond 2038. Fortunately, x86 has padding for this purpose in all the data structures, so we can just add extra fields. With msgid64_ds and shmid64_ds, the data structure is identical to the asm-generic version, which we have already extended. For some reason however, the 64-bit version of semid64_ds ended up with extra padding, so I'm implementing the same approach as the asm-generic version here, by using separate fields for the upper and lower halves of the two timestamps.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
