2021-07-27	s390/boot: move sclp early buffer from fixed address in asm to C	Alexander Egorenkov	1	-0/+9
	To make the decompressor relocatable, the early SCLP buffer with a fixed address must be replaced with a relocatable C buffer of the according size and alignment as required by SCLP. Introduce a new function sclp_early_set_buffer() into the SCLP driver which enables the decompressor to change the SCLP early buffer at any time. This will be useful when the decompressor becomes fully relocatable and might need to change the SCLP early buffer to one with an address < 2G as required by SCLP because it was loaded at an address >= 2G.

2018-06-25	s390/decompressor: avoid reusing uncompressed image objects	Vasily Gorbik	1	-0/+2
	Re-compile ebcdic.c and sclp_early_core.c for the decompressor, using proper decompressor CFLAGS. This also allows to potentially use instrumentation for those files when built for the main kernel image. With kbuild there is no easy way to re-compile a source file from another directory. Bypass ugly rules and Makefile meta-programming with relative path includes of original files.
