[PATCH 01/17] kexec_file: Silence compile warnings

[Philipp Rudo]

When building the kernel with CONFIG_KEXEC_FILE enabled gcc prints a
compile warning multiple times.

In file included from <path>/linux/init/initramfs.c:526:0:
<path>/include/linux/kexec.h:120:9: warning: ‘struct kimage’ declared inside parameter list [enabled by default]
         unsigned long cmdline_len);
         ^
This is because the typedefs for kexec_file_load uses struct kimage before
it is declared. Fix this by simply forward declaring struct kimage.
