Michael Roth b57feed2cc x86/compressed/64: Add identity mappings for setup_data entries ... The decompressed kernel initially relies on the identity map set up by the boot/compressed kernel for accessing things like boot_params. With the recent introduction of SEV-SNP support, the decompressed kernel also needs to access the setup_data entries pointed to by boot_params->hdr.setup_data. This can lead to a crash in the kexec kernel during early boot due to these entries not currently being included in the initial identity map, see thread at Link below. Include mappings for the setup_data entries in the initial identity map.
