commit 8da38ebaad23fe1b0c4a205438676f6356607cfc upstream. Handle the case where microcode gets loaded on the BSP's hyperthread sibling first and the boot_cpu_data's microcode revision doesn't get updated because of early exit due to the siblings sharing a microcode engine. For that, simply write the updated revision on all CPUs unconditionally.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
