Currently the BSP microcode update code examines the initrd very early in the boot process. If SME is active, the initrd is treated as being encrypted but it has not been encrypted (in place) yet. Update the early boot code that encrypts the kernel to also encrypt the initrd so that early BSP microcode updates work.

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.
