CCISS was producing warnings about shifts being greater than the size of
the type and pointers being of incompatible type. Turns out this is
because it's calling do_div on a 32-bit quantity. Upon further
investigation, the sector_t total_size is being assigned to an int, and
then we're calling do_div on that int. Obviously, sector_div is called for
here, and I took the chance to refactor the code a little.

Mistyped an ifdef CONFIG_CPUSETS - fixed.
I doubt that anyone ever noticed. The impact of this typo was
that if someone:
1) was using MPOL_BIND to force off node allocations
2) while using cpusets to constrain memory placement
3) when that cpuset was migrating that jobs memory
4) while the tasks in that job were actively forking
then there was a rare chance that future allocations using
that MPOL_BIND policy would be node local, not off node.

The zonelist may contain zones of nodes that have not been bootstrapped and
we will oops if we try to allocate from those zones. So check if the node
information for the slab and the node have been setup before attempting an
allocation. If it has not been setup then skip that zone.
Usually we will not encounter this situation since the slab bootstrap code
avoids falling back before we have setup the respective nodes but we seem
to have a special needs for pppc.

The reason sky2 driver was locking up on transmit on the Yukon-FE chipset
is that it was misconfiguring the internal RAM buffer so the transmitter
and receiver were sharing the same space.
The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver
sk98lin which is even more f*cked up on this). Then it assigned based on that.
The giveaway was that the registers would only hold 9bits so both RX/TX
had 0..1ff for space. It is a wonder it worked at all!
This patch addresses this, and fixes an easily reproducible hang on Transmit.
Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.

By default route the 8254 over the 8259 and only disable
it on ATI boards where this causes double timer interrupts.
This should unbreak some Nvidia boards where the timer doesn't

VIA board also seemed to have a little trouble with the disabled
8259.
For 2.6.20 we'll try both dynamically without black listing, but I think
for .19 this is the safer approach because it has been already well tested

TARGET_CPUS is the default irq routing poicy. It specifies which cpus the
kernel should aim an irq at. In physflat delivery mode we can route an irq to
a single cpu. But that doesn't mean our default policy should only be a
single cpu is allowed.
By allowing the irq routing code to select from multiple cpus this enables
systems with more irqs then we can service on a single processor to actually
work.
I just audited and tested the code and irqbalance doesn't care, and the
io_apic.c doesn't care if we have extra cpus in the mask. Everything will use
or assume we are using the lowest numbered cpu in the mask if we can't use
them all.
So this should result in no behavior changes except on systems that need it.

And it seems to generate smaller code too, so it's probably
a good thing on its own. With gcc 4.0:
i386:
4683198 902112 480868 6066178 5c9002 vmlinux (before)
4449895 902112 480868 5832875 5900ab vmlinux (after)

Currently some code pieces assume that address returned by find_e820_area()
are page aligned. But looks like find_e820_area() had no such intention
and hence one might end up stomping over some of the data. One such case
is bootmem allocator initialization code stomped over bss.
This patch modified find_e820_area() to return page aligned address. This
might be little wasteful of memory but at the same time probably it is
easier to handle page aligned memory.
