Subject: parisc/kexec: refactor for kernel/Kconfig.kexec
Date: Thu, 6 Jul 2023 18:20:23 -0400
The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide the
ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the equivalent set of
KEXEC and CRASH options.

- kexec is a system call that implements the ability to shutdown your

- but it is independent of the system firmware. And like a reboot
- you can start any kernel with it, not just Linux.
