Subject[PATCH v19 03/13] powerpc: Use ELF fields defined in 'struct kimage'
Date
ELF related fields elf_headers, elf_headers_sz, and elfcorehdr_addr
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'.
