x86: cope with no remap space being allocated for a numa node
When allocating the pgdat's for numa nodes on x86_32 we attempt to place
them in the numa remap space for that node. However should the node not
have any remap space allocated (such as due to having non-ram pages in
the remap location in the node) then we will incorrectly place the pgdat
at zero. Check we have remap available, falling back to node 0 memory
where we do not.
Debugging this showed that the NODE_DATA() for nodes other than node 0
were all NULL. Tracing this back showed that the NODE_DATA() pointers
were being initialised to each nodes remap space. However under
SPARSEMEM remap is disabled which leads to the pgdat's being placed
incorrectly at kernel virtual address 0. Leading to the panic when
attempting to allocate memory from these nodes.
Numa remap was disabled in the commit below. This occured while fixing
problems triggered when attempting to boot x86_32 NUMA SPARSEMEM kernels
on non-numa hardware.
The real problem is believed to be related to other alignment issues in
the regions blocked out from the bootmem allocator for small memory
systems, and has been fixed separately. Therefore re-enable remap for
SPARSMEM, which fixes pgdat allocation issues. Testing confirms that
SPARSMEM NUMA kernels will boot correctly with this part of the change
reverted.

Fixups to ATA ACPI hotplug
The libata-acpi.c code currently accepts hotplug messages from both the
port and the device. This does not match the behaviour of the bay
driver, and may result in confusion when two hotplug requests are
received for the same device. This patch limits the hotplug notification
to removable ACPI devices, which in turn allows it to use the _STA
method to determine whether the device has been removed or inserted.
On removal, devices are marked as detached. On insertion, a hotplug scan
is started. This should avoid lockups caused by the ata layer attempting
to scan devices which have been removed. The uevent sending is moved
outside the spinlock in order to avoid a warning generated by it firing
when interrupts are disabled.

libata: kill hotplug related race condition
Originally, whole reset processing was done while the port is frozen
and SError was cleared during @postreset(). This had two race
conditions. 1: hotplug could occur after reset but before SError is
cleared and libata won't know about it. 2: hotplug could occur after
all the reset is complete but before the port is thawed. As all
events are cleared on thaw, the hotplug event would be lost.
Commit ac371987a81c61c2efbd6931245cdcaf43baad89 kills the first race
by clearing SError during link resume but before link onlineness test.
However, this doesn't fix race #2 and in some cases clearing SError
after SRST is a good idea.
This patch solves this problem by cross checking link onlineness with
classification result after SError is cleared and port is thawed.
Reset is retried if link is online but all devices attached to the
link are unknown. As all devices will be revalidated, this one-way
check is enough to ensure that all devices are detected and
revalidated reliably.
This, luckily, also fixes the cases where host controller returns
bogus status while harddrive is spinning up after hotplug making
classification run before the device sends the first FIS and thus
causes misdetection.
Low level drivers can bypass the logic by setting class explicitly to
ATA_DEV_NONE if ever necessary (currently none requires this).

This patch cleans up sata_promise's mmio accesses.
In sata_promise there are three distinct mmio address spaces:
1. global registers, offsets from host->iomap[PDC_MMIO_BAR]
2. per-port ATA registers, offsets from ap->ioaddr.cmd_addr
3. per-port SATA registers, offsets from ap->ioaddr.scr_addr
The driver currently often fails to indicate which address space
a given mmio base pointer refers to, which is a source of bugs
and confusion (see recent pdc_thaw() irq clearing bug; it's also
been an obstacle for the pending NCQ extensions).
To reduce these problems, adopt a coding style where the name of
a base pointer always indicates which address space it refers to:
1. global registers: host_mmio
2. per-port ATA registers: ata_mmio
3. per-port SATA registers: sata_mmio
Also rearrange register offset definitions to clearly indicate
which address space they belong to, and add a symbolic definition
for the previously hard-coded PHYMODE4 register.

This patch fixes two bugs in sata_promise's irq status clearing paths:
1. When clearing the irq status for a specific port, the driver
read the global SEQMASK register. This is wrong because that
clears the irq status for _all_ ports.
2. pdc_thaw() incorrectly added the PDC_INT_SEQMASK host register
offset to a per-port ata engine base address. This resulted in
it reading the unrelated PDC_PKT_SUBMIT register, which did not
have the desired irq status clearing effect.
In both cases the fix is to read from the port's Command/Status
register. This also matches what Promise's own driver does.

i2c-nforce2: Disable the second SMBus channel on the DFI Lanparty NF4 Expert
i2c: New co-maintainer
Add multi_defconfig, to build a kernel for all supported m68k platforms,
excluding Sun 3 (Sun 3 kernels are incompatible with all other m68k platforms)
The *_ISA type defines are quite generic and cause namespace conflicts
(e.g. with `AMIGAHW_DECLARE(GG2_ISA)' in <asm/amigahw.h>) for some kernel
configurations. Use ISA_TYPE_* to avoid such conflicts.
Use `__builtin_trap()' instead of `asm volatile("illegal")' in the m68k BUG()
macros (as suggested by Andrew Pinski), to kill warnings in code that assumes
BUG() does not return.
m68k: FB_HP300 depends on DIO and doesnt need FB_CFB_FILLRECT
Correct FB_HP300 dependencies:
- FB_HP300 doesn't depend only on HP300, but also on DIO (which depends on
HP300)
- FB_HP300 does not need FB_CFB_FILLRECT

i2c/max6875: Really prevent 24RF08 corruption
i2c-core takes care of the possible corruption of 24RF08 chips for
quite some times, so device devices no longer need to do it. And they
really should not, as applying the prevention twice voids it.
I thought that I had fixed all drivers long ago but apparently I had
missed that one.

i2c: Convert remaining new-style drivers to use module aliasing
Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.
Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.

i2c-nforce2: Disable the second SMBus channel on the DFI Lanparty NF4 Expert
There is a strange chip at 0x2e on the second SMBus channel of the
DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the
system. As there's nothing interesting on this SMBus channel, the
easiest and safest thing to do is to disable it on that board.
This is a better fix to bug #5889 than the it87 driver update that was
done originally:

i2c: New co-maintainer
Ben Dooks agreed to become my co-maintainer for the i2c subsystem. In
particular, Ben will help with drivers for embedded systems, of which
my experience is inexistent. Thanks Ben and welcome on board!

SUNRPC: AUTH_SYS "machine creds" shouldn't use negative valued uid/gid
Apparently this causes Solaris 10 servers to refuse our NFSv4 SETCLIENTID
calls. Fall back to root creds for now, since most servers that care are
very likely to have root squashing enabled.
