Currently in fixup_cede0_latency() code, we perform the fixup the CEDE(0) exit latency value only if minimum advertized extended CEDE latency values are less than 10us. This was done so as to not break the expected behaviour on POWER8 platforms where the advertised latency was higher than the default 10us, which would delay the SMT folding on the core. However, after the earlier patch "cpuidle/pseries: Fixup CEDE0 latency only for POWER10 onwards", we can be sure that the fixup of CEDE0 latency is going to happen only from POWER10 onwards. Hence unconditionally use the minimum exit latency provided by the platform. Signed-off-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 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.
