Merge tag 'v4.18-rc3' into docs-next

Browse Source 
-rc1 broke the docs build due to changes in the e100/e1000 drivers; -rc3
got the fixes via the networking tree.  Pull in -rc3 so that the docs tree
can actually build the docs again.

``intel_pstate`` exposes several global attributes (files) in ``sysfs`` to
control its functionality at the system level. They are located in the

CPUs.

``hwp_dynamic_boost``
This attribute is only present if ``intel_pstate`` works in the
`active mode with the HWP feature enabled <Active Mode With HWP_>`_ in
the processor. If set (equal to 1), it causes the minimum P-state limit
to be increased dynamically for a short time whenever a task previously
waiting on I/O is selected to run on a given logical CPU (the purpose
of this mechanism is to improve performance).
This setting has no effect on logical CPUs whose minimum P-state limit
is directly set to the highest non-turbo P-state or above it.
