[PATCH v5 14/17] elf: Introduce elf64_phdr_size() helper

[sashiko-bot at kernel.org]

> Add a common helper to compute the total size of an ELF64 header
> (Ehdr + program headers) from the number of program headers.
> Replace open-coded calculations in powerpc, x86, vmcore,
> and crash_core.
> 
> On ppc64, struct elfhdr maps to elf64_hdr, so the powerpc change
> is a pure cleanup.
> 
> No functional change intended.
