Subject: [PATCH v19 02/13] arm64: Use ELF fields defined in 'struct kimage'

From: Lakshmi Ramasubramanian <[email-masked]>
Date: Sun, 21 Feb 2021 09:49:19 -0800

ELF related fields elf_headers, elf_headers_sz, and elf_headers_mem
have been moved from 'struct kimage_arch' to 'struct kimage' as
elf_headers, elf_headers_sz, and elf_load_addr respectively.

Use the ELF fields defined in 'struct kimage'.

Fixes: 33488dc4d61f ("of: Add a common kexec FDT setup function")
