[v1,04/21] ia64/kexec: refactor for kernel/Kconfig.kexec

Commit Message

Eric DeVolder June 12, 2023, 5:27 p.m. UTC

The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_HAS_ and ARCH_SUPPORTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

-	  kexec is a system call that implements the ability to shutdown your
-	  current kernel, and to start another kernel.  It is like a reboot
-	  but it is independent of the system firmware.   And like a reboot
-	  you can start any kernel with it, not just Linux.
-
-	  The name comes from the similarity to the exec system call.
-
-	  It is an ongoing process to be certain the hardware in a machine
-	  is properly shutdown, so do not be surprised if this code does not
-	  initially work for you.  As of this writing the exact hardware
-	  interface is strongly in flux, so no good recommendation can be
