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).

sata_promise: mmio access cleanups
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.

sata_promise: fix irq clearing buglets
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.

[POWERPC] 4xx: Workaround for CHIP_11 Errata
The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that
causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction
requests that cross the end-of-memory-range boundary. Since the DDR
controller only returns the valid portion of a read request, the bridge
will prevent other PLB masters from completing their transactions.
This implements the recommended workaround for this errata for chips that
use older versions of firmware that do not already handle it. The last
4KiB of memory are hidden from the kernel to prevent the problem
transactions from occurring.

sh: Fix up restorer in debug_trap exception return path.
There are a few different types of debug trap exceptions, though now
that they are all going through a special jump table, the restorer needs
to be unified as well.
Presently this is falling through the ret_from_fork path, which more or
less does the right thing on SH-3/4 whilst being completely unsuitable on
MMU-less targets.
Ultimately what we want here is a branch through the platform's
restore_all directly, without worrying about the retval being clobbered.
We can accomplish that through a branch to __restore_all directly, so
switch it so we come back from the jump table and branch to the restorer.
This fixes up a recursion in the nommu WARN_ON() path, as well as some
other userspace nastiness where said recursion caused serious stack
corruption.

KVM: x86 emulator: fix writes to registers with modrm encodings
A register destination encoded with a mod=3 encoding left dst.ptr NULL.
Normally we don't trap writes to registers, but in the case of smsw, we do.
Fix by pointing dst.ptr at the destination register.

Two changes are necessary to enable proper operation of the DM9000 device with
the Colibri PXA 270 board: firstly, the IRQ type needs to be configured for
rising edge interrupts, and secondly this configuration needs to be
communicated through to the DM9000.
