Normally vmlinux for arm64 is of ET_EXEC type, while if built with
CONFIG_RANDAMIZE_BASE (that is KASLR), it will be of ET_DYN type.
Meanwhile, physical address field of segments in vmlinux has actually
the same value as virtual address field.
Accordingly, in this case, it totally makes no sense to check for
validity of segments against physical memory ranges and, if necessary,
relocate them in elf_exec_load() on arm64.
This patch allows to unconditionally skip the check on arm64.

When building in PPC64 little endian mode, the compiler is now using the
new ABI v2. Among other changes, this new ABI removes the function
descriptors and changes the way the TOC address is computed when entering a
C function.
The purgatory assembly part where the dot symbols are removed, and ELF
relocation code are impacted in this patch.

This patch adds kdump support for s390 to the kexec tool and enables the
"--load-panic" option. When loading the kdump kernel and ramdisk we add the
address of the crashkernel memory to the normal load address.
