6e61e85b09 [MIPS] Sibyte: Improve interrupt latency again for sb1250/bcm1480
this patch restores the behaviour of the old (assembly-written)
interrupt handler, the handler is left as soon as a single interrupt
cause is handled.

f1aaee53f2 [PATCH] lockdep: annotate mm/slab.c
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

Using the address type causes problems if the address type was const

a83f982313 [SPARC]: Fix OF register translations under sub-PCI busses.
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

not a Simba APB bridge.

Add logic to handle two special cases:

1) device behind EBUS, which sits on PCI
2) PCI controller interrupts

91d1ed1a6d [SERIAL] sunsu: Handle keyboard and mouse ports directly.
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.

a23c3a86e9 [SPARC64]: Fix 2 bugs in sabre_irq_build()
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.

ffadcc2ff4 [PATCH] PCI: PCIE power management quirk
When changing power states from D0->DX and then from DX->D0, some
Intel PCIE chipsets will cause a device reset to occur.  This will
cause problems for any D State other than D3, since any state
information that the driver will expect to be present coming from
a D1 or D2 state will have been cleared.  This patch addes a
flag to the pci_dev structure to indicate that devices should
not use states D1 or D2, and will set that flag for the affected
chipsets.  This patch also modifies pci_set_power_state() so that
when a device driver tries to set the power state on
a device that is downstream from an affected chipset, or on one
of the affected devices it only allows state changes to or
from D0 & D3.  In addition, this patch allows the delay time
between D3->D0 to be changed via a quirk.  These chipsets also
need additional time to change states beyond the normal 10ms.
