Neil Horman d6580a9f15 kexec: sysrq: simplify sysrq-c handler ... Currently the sysrq-c handler is bit over-engineered. Its behavior is dependent on a few compile time and run time factors that alter its behavior which is really unnecessecary. If CONFIG_KEXEC is not configured, sysrq-c, crashes the system with a NULL pointer dereference. If CONFIG_KEXEC is configured, it calls crash_kexec directly, which implies that the kexec kernel will either be booted (if its been previously loaded), or it will simply do nothing (the no kexec kernel has been loaded). It would be much easier to just simplify the whole thing to dereference a NULL pointer all the time regardless of configuration. That way, it will always try to crash the system, and if a kexec kernel has been loaded into reserved space, it will still boot from the page fault trap handler (assuming panic_on_oops is set appropriately).
