Get rid of all the IPI-sending functions and their wrappers and use those which are supposed to be called on each CPU. Thus: - microcode_init_cpu() gets called on each CPU on init, applying any new microcode that the driver might've found on the filesystem. - mc_cpu_starting() simply tries to apply cached microcode as this is the cpuhp starting callback which gets called on CPU resume too. Even if the driver init function is a late initcall, there is no filesystem by then (not even a hdd driver has been loaded yet) so a new firmware load attempt cannot simply be done. It is pointless anyway - for that there's late loading if one really needs it.

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.
