do_gettimeofday() is deprecated since it will stop working in 2038 on 32-bit platforms, leading to incorrect times passed to the firmware. On 64-bit platforms the current code appears to be fine, as the calculation passes an 8-bit century number into the firmware that can represent times long in the future (possibly until 25599). Using ktime_get_real_seconds() to get a 64-bit seconds value and time64_to_tm() to convert it into the firmware format greatly simplifies the ips timekeeping code, makes 32-bit and 64-bit behave the same way here, and gets us closer to removing the deprecated interfaces.

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.
