cputime_t was a core kernel type, removed by commits ed5c8c854f2b..b672592f0221. As explained in commitb672592f02("sched/cputime: Remove generic asm headers"), the final cleanup is for the arch to provide cputime_to_nsec[s](). Commitade7667a98("powerpc: Add cputime_to_nsecs()") did that, but justdidn't remove the then-unused cputime_to_usecs(), cputime_t type, and associated remnants.

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.
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.
