Doc Text .`kexec` as a Technology Preview

The `kexec` system call has been provided as a Technology Preview. This system call enables loading and booting into another kernel from the currently running kernel, thus performing the function of the boot loader from within the kernel. Hardware initialization, which is normally done during a standard system boot, is not performed during a kexec boot, which significantly reduces the time required for a reboot.

.The ‘kexec fast reboot` feature is available as Technology Preview

The `kexec fast reboot` feature continues to be available as a Technology Preview. `kexec fast reboot` significantly speeds the boot process faster by allowing the kernel to boot directly into the second kernel without passing through the Basic Input/Output System (BIOS) first. To use this feature, load the `kexec` kernel manually, and then reboot the operating system.
