Marcelo Henrique Cerri f4938792af s390/decompressor: fix initrd corruption caused by bss clear ... commit d82c0d12c92705ef468683c9b7a8298dd61ed191 upstream. Reorder the operations in decompress_kernel() to ensure initrd is moved to a safe location before the bss section is zeroed. During decompression bss can overlap with the initrd and this can corrupt the initrd contents depending on the size of the compressed kernel (which affects where the initrd is placed by the bootloader) and the size of the bss section of the decompressor. Also use the correct initrd size when checking for overlaps with parmblock.
