2020-03-03	kbuild: generate autoksyms.h early	Quentin Perret	1	-1/+2
	When doing a cold build, autoksyms.h starts empty, and is updated late in the build process to have visibility over the symbols used by in-tree drivers. But since the symbol whitelist is known upfront, it can be used to pre-populate autoksyms.h and maximize the amount of code that can be compiled to its final state in a single pass, hence reducing build time. Do this by using gen_autoksyms.sh to initialize autoksyms.h instead of creating an empty file.

2020-03-03	kbuild: split adjust_autoksyms.sh in two parts	Quentin Perret	1	-0/+51
	In order to prepare the ground for a build-time optimization, split adjust_autoksyms.sh into two scripts: one that generates autoksyms.h based on all currently available information (whitelist, and .mod files), and the other to inspect the diff between two versions of autoksyms.h and trigger appropriate rebuilds.
