x86/reboot: Add Dell Optiplex 7450 AIO reboot quirk
Dell Optiplex 7450 AIO works with BOOT_ACPI; however, the quirk for "OptiPlex 745" changes its boot method to BOOT_BIOS and causes 7450 AIO hangs when rebooting; as a result, 7450 AIO is appended to overwrite BOOT_BIOS by BOOT_ACPI in order not to break the original 745 series Signed-off-by: Alex Hung <alex.hung@canonical.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
