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.

Currently we count the number of lpevents processed in 3 seperate places.

One of these counters is never read, so just remove it. This means
hvlpevent_queue_process() no longer needs to return the number of events
processed.

Now that we've renamed the xItLpQueue structure, rename the functions that
operate on it also.

Because there's only one ItLpQueue and we know where it is, ie. xItLpQueue,
there's no point passing pointers to it it around all over the place.

The iSeries code keeps a pointer to the ItLpQueue in its paca struct. But
all these pointers end up pointing to the one place, ie. xItLpQueue.

So remove the pointer from the paca struct and just refer to xItLpQueue
directly where needed.

The only complication is that the spread_lpevents logic was implemented by
having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to
process events. Instead we just compare the spread_lpevents value to the
processor id to get the same behaviour.

This patch removes some unused bits from HvCall.h and some unneeded #includes
from other files.  Also includes ItLpQueue.h in paca.h in preference to a stub
declaration of struct ItLpQueue.

For quite a while, there has existed a hypervisor bug on legacy iSeries
which means that we do not get the boot time set in the kernel.  This
patch works around that bug.  This was most noticable when the root
partition needed to be checked at every boot as the kernel thought it
was some time in 1905 until user mode reset the time correctly.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
