Subject: [SPARC64]: Unify timer interrupt handler.

Things were scattered all over the place, split between
SMP and non-SMP.

Unify it all so that dyntick support is easier to add.

Subject: [SPARC64]: Add clocksource/clockevents support.

I'd like to thank John Stul and others for helping
me along the way.

A lot of cleanups fell out of this.  For example, the get_compare()
tick_op was totally unused, so was deleted.  And the most often used
tick_op members were grouped together for cache-friendlyness.

The sparc64 TSC is given to the kernel as a one-shot timer.

tick_ops->init_timer() simply turns off the privileged bit in
the tick register (when possible), and disables the interrupt
by setting bit 63 in the compare register.  The ->disable_irq()
op also sets this bit.

tick_ops->add_compare() is changed to:

1) Add the given delta to "tick" not to "compare"
2) Return a boolean which, if true, means that the tick
   value read after writing the compare value was found
   to have incremented past the initial tick value.  This
   mirrors logic used in the HPET driver's ->next_event()
   method.

Each tick_ops implementation also now provides a name string.
And we feed this into the clocksource and clockevents layers.

- Removes days_in_mo[], as it's almost identical to month_days[]
- Use the leapyear() macro

From: "David S. Miller" <davem@sunset.davemloft.net>
Date: Thu, 29 Mar 2007 01:28:51 -0700
Subject: [SPARC]: Use strcasecmp for OFW property name comparisons.

This allows us to simplify sharing code with powerpc which
has properties that have various forms of capitalization
when on the sparc64 side the property is all lower-case.

Subject: [SPARC64]: Internalize pci_memspace_mask.

The only user was bus_dvma_to_mem() which is no longer used
by any driver, so kill that, and the export of pci_memspace_mask.

The only user now is the PCI mmap support code.

Subject: [SPARC64]: Fix sabre pci controllers with new probing scheme.

The SIMBA APB bridge is strange, it is a PCI bridge but it lacks
some standard OF properties, in particular it lacks a 'ranges'
property.

What you have to do is read the IO and MEM range registers in
the APB bridge to determine the ranges handled by each bridge.
So fill in the bus resources by doing that.

Since we now handle this quirk in the generic PCI and OF device
probing layers, we can flat out eliminate all of that code from
the sabre pci controller driver.

In fact we can thus eliminate completely another quirk of the sabre
driver.  It tried to make the two APB bridges look like PBMs but that
makes zero sense now (and it's questionable whether it ever made sense).
So now just use pbm_A and probe the whole PCI hierarchy using that as
the root.

This simplification allows many future cleanups to occur.

Also, I've found yet another quirk that needs to be worked around
while testing this.  You can't use the 'class-code' OF firmware
property, especially for IDE controllers.  We have to read the value
out of PCI config space or else we'll see the value the device was
showing before it was programmed into native mode.

I'm starting to think it might be wise to just read all of the values
out of PCI config space instead of using the OF properties. :-/

Subject: [SPARC64]: Kill pci_controller->pbms_same_domain

We don't do the "Simba APB is a PBM" bogosity for Sabre
controllers any longer, so this pbms_same_domain thing
is no longer necessary.

We fake up a dummy one in all cases because that is the simplest
thing to do and it happens to be necessary for hypervisor systems.

Subject: [SPARC64]: Force dummy host controller onto bus zero.

This helps deal with the invisible bridge that sits between
the host controller and the top-most visisble PCI devices
on hypervisor systems.

For example, on T1000 the bus-range property says 2 --> 4
and so there is a PCI express bridge at bus 2, devfn 0, etc.

So if we don't force the dummy host controller to bus zero,
we'll try to create two devices with the same domain/bus/devfn
triplet.

Also, add some more log diagnostics to make debugging stuff like this
easyer.

Subject: [SPARC64]: Use SPARSEMEM_STATIC

Decrease the SECTION_SIZE_BITS --> MAX_PHYSADDR_BITS
range a little bit.

The cost of going to SPARSEMEM_STATIC becomes 8K of BSS space, and in
return we save a pointer dereferences on every page struct lookup.
Even better we hit the main kernel image for the base address which is
in a hugepage locked TLB entry.

Subject: [SPARC64]: Privatize sun4u_get_pte() and fix name.

__get_phys is only called from init.c as is prom_virt_to_phys(),
__get_iospace() is not called at all, and sun4u_get_pte() is largely
misnamed.

Privatize the implementation and helper functions of
sun4u_get_phys() to mm/init.c, and rename to
kvaddr_to_paddr().

The only used of this thing is flush_icache_range(), and thus
things can be considerably further simplified.  For example,
we should only see module or PAGE_OFFSET kernel addresses here,
so we don't need the OBP firmware range handling at all.

We now report everything i386 does except for highmem which
doesn't apply.

Subject: [SPARC64]: Kill sparc_ultra_dump_{i,d}tlb()

While useful in odd circumstances to debug something, they are
normally totally unused and anyone can fetch this code out of the
history if they really need it.

And in any event, the person who needs this kind of code is usually me
:-)
