With some memory model other than FLATMEM, the single node can
contains some holes so there might be many invalid pages. For
example, with two 256M memory and one 256M hole, some variables
(num_physpage, totalpages, nr_kernel_pages, nr_all_pages, etc.) will
indicate that there are 768MB on this system. This is not desired
because, for example, alloc_large_system_hash() allocates too many
entries.
Use free_area_init_node() with counted zholes_size[] instead of
free_area_init().
For num_physpages, use number of ram pages instead of max_low_pfn.

1. MIPS should select SPARSEMEM_STATIC since allocating bootmem in
memory_present() will corrupt bootmap area.
2. pfn_valid() for SPARSEMEM is defined in linux/mmzone.h

this patch restores the behaviour of the old (assembly-written)
interrupt handler, the handler is left as soon as a single interrupt

mm/slab.c uses nested locking when dealing with 'off-slab'
caches, in that case it allocates the slab header from the
(on-slab) kmalloc caches. Teach the lock validator about
this by putting all on-slab caches into a separate class.
this patch has no effect on non-lockdep kernels.

Keep the result holder variable the same type as the quantity we are
retreiving in the get_user() macro - don't go through a pointer version
of the user space address type.
Using the address type causes problems if the address type was const
(newer versions of gcc quite rightly error out for that condition).

There is an implicit assumption in the code that ranges will translate
to something that can fit in 2 32-bit cells, or a 64-bit value. For
certain kinds of things below PCI this isn't necessarily true.
Here is what the relevant OF device hierarchy looks like for one of
the serial controllers on an Ultra5:
Node 0xf005f1e0
ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000
01000000.00000000.00000000.000001fe.02000000.00000000.01000000
02000000.00000000.00000000.000001ff.00000000.00000001.00000000
03000000.00000000.00000000.000001ff.00000000.00000001.00000000
device_type: 'pci'
model: 'SUNW,sabre'
Node 0xf005f9d4
device_type: 'pci'
model: 'SUNW,simba'
Node 0xf0060d24
ranges: 00000010.00000000 82010810.00000000.f0000000 01000000
00000014.00000000 82010814.00000000.f1000000 00800000
name: 'ebus'
Node 0xf0062dac
reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8
device_type: 'serial'
name: 'su'
So the correct translation here is:
1) Match "su" register to second ranges entry of 'ebus', which translates
into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which
gives us "82010814.00000000.f13083f8".
2) Pass-through "SUNW,simba" since it lacks ranges property
3) Match "82010814.00000000.f13083f8" to third ranges property of PCI
controller node 'SUNW,sabre', and we arrive at the final physical
MMIO address of "0x1fff13083f8".
Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell
value, and we couldn't perform a pass-thru on it either.
It was easiest to just stop splitting the ranges application operation
between two methods, ->map and ->translate, and just let ->map do all
the work. That way it would work purely on 32-bit cell arrays instead
of having to "return" some value like a u64.
It's still not %100 correct because the out-of-range check is still
done using the 64 least significant bits of the range and address.
But it does work for all the cases I've thrown at it so far.

It is only needed when there is a PCI-PCI bridge sitting
between the device and the PCI host controller which is
not a Simba APB bridge.
Add logic to handle two special cases:
1) device behind EBUS, which sits on PCI
2) PCI controller interrupts

The sunsu_ports[] array exists merely to be able to easily
use an integer index to get at the proper serial console
port struct.
We size this only for real ports, not for the keyboard and
mouse, and thus keyboard and mouse port registration would
fail.
Fix this by dynamically allocating the port struct for the
keyboard and mouse, instead of using the sunsu_ports[]
array.

When installing the IRQ pre-handler, we were not setting up the second
argument correctly. It should be a pointer to the sabre_irq_data, not
the config space PIO address.
Furthermore, we only need this pre-handler installed if the device
sits behind a PCI bridge that is not Sabre or Simba/APB.

if IO space is not available"
This reverts commit 5040cb8b7e61b7a03e8837920b9eb2c839bb1947.
It breaks previously working ide-cs PIO configurations, causing problems
like
ide2: I/O resource 0xF883200E-0xF883200E not free.
ide2: ports already in use, skipping probe
rather than a working kernel.

solve (see
