kexec_load_disabled affects both ``kexec_load`` and ``kexec_file_load``
syscalls. Make it explicit.

Add two parameter to specify how many times a kexec kernel can be loaded.
These parameter allow hardening the system.
While we are at it, fix a documentation issue and refactor some code.

Both syscalls (kexec and kexec_file) do the same check, lets factor it
out.

Add two parameters to specify how many times a kexec kernel can be loaded.
The sysadmin can set different limits for kexec panic and kexec reboot
kernels.
The value can be modified at runtime via sysctl, but only with a value
smaller than the current one (except -1).

Hi all,
I am happy to announce the release of kexec-tools 2.0.26.
This is a feature release coinciding with the release of v6.1
of the Linux Kernel.
This release can be downloaded from kernel.org:
http://kernel.org/pub/linux/utils/kernel/kexec/kexec-tools-2.0.26.tar.xz
