Robin Holt 7b6d864b48 reboot: arm: change reboot_mode to use enum reboot_mode
Preparing to move the parsing of reboot= to generic kernel code forces
the change in reboot_mode handling to use the enum.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Olof Johansson 86dfe446c2 ARM: fix builds due to missing <asm/system_misc.h> includes
This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.
