Instead of setting a fixed floor at lowest_nonlinear_perf, use the min_limit_perf value, so that it gives the user the freedom to lower the floor further. There are two minimum frequency/perf limits that we need to consider in the adjust_perf callback. One provided by schedutil i.e. the sg_cpu->bw_min value passed in _min_perf arg, another is the effective value of min_freq_qos request that is updated in cpudata->min_limit_perf. Modify the code to use the bigger of these two values. Signed-off-by: Dhananjay Ugwekar <dhananjay.ugwekar@amd.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Gautham R.

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 reStructuredText 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.
