LoongArch: Automatically disable kaslr if boot from kexec_file
commit c8168b4faf1d62cbb320a3e518ad31cdd567cb05 upstream.
Automatically disable kaslr when the kernel loads from kexec_file.
kexec_file loads the secondary kernel image to a non-linked address,
inherently providing KASLR-like randomization.
However, on LoongArch where System RAM may be non-contiguous, enabling
KASLR for the second kernel may relocate it to an invalid memory region
and cause a boot failure. Thus, we disable KASLR when "kexec_file" is
detected in the command line.
To ensure compatibility with older kernels loaded via kexec_file, this
patch should be backported to stable branches.
