Remove struct pt_regs * from all handlers.
Also remove the regs argument from get_irq() functions.

There are a few places in the kernel where the init task is signaled. The
ctrl+alt+del sequence is one them. It kills a task, usually init, using a
cached pid (cad_pid).
This patch replaces the pid_t by a struct pid to avoid pid wrap around
problem. The struct pid is initialized at boot time in init() and can be
modified through systctl with
/proc/sys/kernel/cad_pid
[ I haven't found any distro using it ? ]
It also introduces a small helper routine kill_cad_pid() which is used
where it seemed ok to use cad_pid instead of pid 1.

Not even the iSeries maintainer seems to have access to this legendary
piranha simulator. It adds a bit of ugliness in the common time init
code, and if it's no longer used we might as well be done with it and
remove the bloat.

Make mf_get_rtc(), mf_get_boot_rtc() and mf_set_rtc() static, cause they can
be. We need to move mf_set_rtc() to avoid a forward declaration.

These routines just call through to the mf routines, so point ppc_md straight
at the mf routines. We need to pass the cmd through to mf_reboot to make it
work, but that seems reasonable.

Some cleanups in the iSeries code.
- Make mf_display_progress() check mf_initialized rather than the caller.
- Set mf_initialized in mf_init() rather than in setup.c
- Then move mf_initialized into mf.c, the only place it's used.
- Move the mf related logic from iSeries_progress() to mf_display_progress()
- Use a #define to size the pending_event_prealloc array
- Use that define in the initialsation loop rather than sizeof jiggery pokery
- Remove stupid comment(s)
- Mark stuff static and/or __init

A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

The only real user of this file outside platforms/iseries was
drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR()
so we move that to abs_addr.h (and lowercase it).

iSeries_setup.c becomes setup.c
iSeries_setup.h becomes setup.h
mf.c retains its name
Also moved iSeries_[gs]et_rtc_time and iSeries_get_boot_time into
mf.c since they are just small wrappers around mf_ functions.
