Change aggr_time_limit_encoded() to properly calculate the aggregation time limit to use for IPA v4.5. Older IPA versions program the AGGR_GRANULARITY field of the of the COUNTER_CFG register to set the granularity of the aggregation timer, which we configure to be 500 microseconds. Instead, IPA v4.5 selects between two possible granularity values derived from the 19.2 MHz Qtime clock. These granularities are 100 microseconds or 1 millisecond per tick. We use the smaller granularity if possible, unless the desired period is too large to be specified that way.

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.
