This reverts commit 8dd9453737822469837d48d5da3785ce70fb2118.
This fixes a boot failure reported by Robert Reif.
The code above the section change expects to fallthrough, so
we can't make such a section change here.

Shift the first year to 1968 for Sun SPARC machines.
Move this logic from platform specific files to rtc driver
as this fixes problems with calculating a century bit.

Latest mainline gives this section mismatch on sparc:
The function current_pc() references
the variable __init no_sun4u_here.
This is often because current_pc lacks a __init
annotation or the annotation of no_sun4u_here is wrong.
Since current_pc() is used only in early time, it is correct to
put it in .init section.

The latest mainline gives this section mismatch on sparc:
The function __devinit apc_probe() references
a variable __initdata apc_no_idle.
If apc_no_idle is only used by apc_probe then
annotate apc_no_idle with a matching annotation.
Since the commit 7e7e2f035663c5ceb029bfb9d91e75099b0a5625,
apc_probe() is on __devinit so we have to correct apc_no_idle
which is referenced by this function.

Right now, there is no notifier that is called on a new cpu, before the new
cpu begins processing interrupts/softirqs.
Various kernel function would need that notification, e.g. kvm works around
by calling smp_call_function_single(), rcu polls cpu_online_map.
The patch adds a CPU_STARTING notification. It also adds a helper function
that sends the message to all cpu_chain handlers.
Tested on x86-64.
All other archs are untested. Especially on sparc, I'm not sure if I got
it right.

Here is an updated version of a patch I wrote 6 years ago
http://marc.info/?l=linux-sparc&m=103939103607617&w=2
that simplifies interrupt mask lookup. It's main purpose
is to add VME bus support but it's really a cleanup of the mask code.

This is the only use of the clear_profile_irq() btfixup entry,
which just eats up lots of dead space on other platform types.
A subsequent commit will delete the other implementations and
the btfixup entry as well.

As noticed by Russell King, we were not setting this properly
to the number of entries, but rather the total size.
This results in the core dumping code allocating waayyyy too

When a device is under an EBUS or ISA bus, the resource flags
don't get set properly.
Fix this by re-evaluating the resource flags at each level of
bus as we apply ranges on the way to the root. And let PCI
override any existing flags setting, but don't let the
default flags calculator make such overrides.

Use rtc subsystem for sparc32 architecture.
Actually, only one driver is needed: m48t59
as it supports the most common clocks on sparc32
machines: m48t08 and m48t02.

The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges'
property, but we should pass the translation up to the parent node so
that the SBUS level ranges get applied.

While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.
And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.
