4fa2564a6f [PATCH] i386 machine_power_off cleanup
Call machine_shutdown() to move to the boot cpu
and disable apics.  Both acpi_power_off and
apm_power_off want to move to the boot cpu.
and we are already disabling the local apics
so calling machine_shutdown simply reuses
code.

ia64 doesn't have a special path in power_off
for efi so there is no reason i386 should.  If
we really need to call the efi power off path
the efi driver can set pm_power_off like everyone
else.

68acc05d01 [PATCH] pcwd.c: Call kernel_power_off not machine_power_off
The call appears to come from process context so kernel_power_off
should be safe.  And acpi_power_off won't necessarily work if you just
call machine_power_off.

804ebf46d5 [PATCH] 68328serial: sysrq should use emergency_reboot
The 68328serial.c driver has a weird local reimplementation of
magic sysrq.  The code is architecture specific enough that calling
machine_restart() is probably ok.  But there is no reason not to call
emergency_restart() so do so.

4de8b9b760 [PATCH] Update sysrq-B to use emergency_restart()
sysrq calls into the reboot path from an interrupt handler
we can either push the code do into process context and
call kernel_restart and get a clean reboot or we can simply
reboot the machine, and increase our chances of actually
rebooting.  emergency_reboot() seems like the closest match
to what we have previously done, and what we want.

59586e5a26 [PATCH] Don't export machine_restart, machine_halt, or machine_power_off.
machine_restart, machine_halt and machine_power_off are machine
specific hooks deep into the reboot logic, that modules
have no business messing with.  Usually code should be calling
kernel_restart, kernel_halt, kernel_power_off, or
emergency_restart. So don't export machine_restart,
machine_halt, and machine_power_off so we can catch buggy users.

7c9034735e [PATCH] Add emergency_restart()
When the kernel is working well and we want to restart cleanly
kernel_restart is the function to use.   But in many instances
the kernel wants to reboot when thing are expected to be working
very badly such as from panic or a software watchdog handler.

This patch adds the function emergency_restart() so that
callers can be clear what semantics they expect when calling
restart.  emergency_restart() is expected to be callable
from interrupt context and possibly reliable in even more
trying circumstances.

This is an initial generic implementation for all architectures.
