[PATCH -v11 resend 10/11] arm, change reboot_mode to use enum reboot_mode

From: Robin Holt
Date: Thu Jun 06 2013 - 07:48:11 EST

Next message: Robin Holt: "[PATCH -v11 resend 11/11] Move arch/x86 reboot= handling to generic kernel."
Previous message: Robin Holt: "[PATCH -v11 resend 09/11] arm, prepare reboot_mode for moving to generic kernel code."
In reply to: Robin Holt: "[PATCH -v11 resend 09/11] arm, prepare reboot_mode for moving to generic kernel code."
Next in thread: Robin Holt: "[PATCH -v11 resend 11/11] Move arch/x86 reboot= handling to generic kernel."
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Preparing to move the parsing of reboot= to generic kernel code
forces the change in reboot_mode handling to use the enum.
