Hi,
This series makes the kexec_file_load() syscall support to load Image binary file.
At the same time, corresponding support for kexec-tools had been pushed to my repo[1].
Now, we can leverage that kexec-tools and this series to use the
kexec_load() or kexec_file_load() syscall to boot both vmlinux
and Image file, as seen in these combo tests:
```
1. kexec -l vmlinux [other options] // or boot paniced kernel with -p
2. kexec -l Image
3. kexec -s -l vmlinux
4. kexec -s -l Image
```
Though all of the aforementioned tests had been passed in my RV64 Qemu-virt,
it should be noted that tests 3 and 4 should be the emphasis for the current series.
