[PATCH v2 0/2] LoongArch: Add single kernel image implementation for kdump

[Youling Tang]

Add single kernel image implementation for kdump.

kexec-tools needs to be updated to make sure it jumps to the correct
kernel entry.

When kaslr is enabled, it is best to add the "nokaslr" parameter when
performing kdump operations to ensure that the randomized kernel
position conflicts with other segments (such as initrd loading
position).
eg: sudo kexec -p vmlinux.efi --reuse-cmdline --append="nokaslr"

Changes from v1 to v2:

- Rewrite commit message.
