[Xen-devel] [patch 4/4] kexec: dont initialise regions in reserve_memory()

[Simon Horman <horms@xxxxxxxxxxxx>]

There is no need to initialise efi_memmap_res and boot_param_res in
reserve_memory() for the initial xen domain as it is done in
machine_kexec_setup_resources() using values from the kexec hypercall.
