This patch supports loading additional firmware file through
request_firmware().
A firmware file may include a header followed by several blocks
which have different types of firmware. Currently, the supported
types are RTL_FW_END, RTL_FW_PLA, and RTL_FW_USB.
The firmware is used to fix some

This allows us to check if a remote CPU runs context tracking
(ie: is nohz_full). We'll need that to reliably support "nice"
accounting on kcpustat.

This function is a leftover from old removal or rename. We can drop it.

Kcpustat is not correctly supported on nohz_full CPUs. The tick doesn't
fire and the cputime therefore doesn't move forward. The issue has shown
up after the vanishing of the remaining 1Hz which has made the stall
visible.
We are solving that with checking the task running on a CPU through RCU
Standardize the naming on top of the context_tracking_enabled_*() base.
Also make it clear we are checking the context tracking state of the
*current* CPU with this function. We'll need to add an API to check that
state on remote CPUs as well, so we must disambiguate the naming.
Signed-off-by:
Now that we have a vtime safe kcpustat accessor for CPUTIME_SYSTEM, use
it to start fixing frozen kcpustat values on nohz_full CPUs.

(ie: is nohz_full). We'll need that to reliably support reading kcpustat
on nohz_full CPUs.
Also simplify a bit the condition in the local flavoured function while
at it.
