2024-02-16	arm64: head: Move early kernel mapping routines into C code	Ard Biesheuvel	1	-0/+2
	The asm version of the kernel mapping code works fine for creating a coarse grained identity map, but for mapping the kernel down to its exact boundaries with the right attributes, it is not suitable. This is why we create a preliminary RWX kernel mapping first, and then rebuild it from scratch later on. So let's reimplement this in C, in a way that will make it unnecessary to create the kernel page tables yet another time in paging_init().

2024-02-16	arm64: head: move relocation handling to C code	Ard Biesheuvel	1	-0/+62
	Now that we have a mini C runtime before the kernel mapping is up, we can move the non-trivial relocation processing code out of head.S and reimplement it in C.
