From a698240df0c43278b2d1d7259c8e7a6926c63112 Mon Sep 17 00:00:00 2001
From: "Matthew S. Turnbull" <sparky@bluefang-logic.com>

Subject: grub-mkconfig/10_linux: Support multiple early initrd images
Add support for multiple, shared, early initrd images. These early
images will be loaded in the order declared, and all will be loaded
before the initrd image.
While many classes of data can be provided by early images, the
immediate use case would be for distributions to provide CPU
microcode to mitigate the Meltdown and Spectre vulnerabilities.
There are two environment variables provided for declaring the early
images.
* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare
images that are provided by the distribution or installed packages.
If undeclared, this will default to a set of common microcode image
names.
* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
images will be loaded after the stock images.
These separate configurations allow the distribution and user to
declare different image sets without clobbering each other.
This also makes a minor update to ensure that UUID partition labels
stay disabled when no initrd image is found, even if early images are
present.
This is a continuation of a previous patch published by Christian
Hesse in 2016:
