The PXA25x and PXA27x USB device controller register definitions are
different. Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.
This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.
Remove these definitions from pxa-regs.h, and place them in separate
files. Include these files where appropriate.
Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

Patch mainly from Eric Miao, with minor edits by rmk.
Note: PWM0 and PWM2 share the same register I/O space and clock gating
on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of
PWM0. And this is also true for PWM1/3.

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.

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.

Currently is_valid_bugaddr() is true for anything >= PAGE_OFFSET, which
happens to be 0 on nommu configurations. Make this a bit smarter by just
reading in the opcode and comparing it against the trap type that we
already know. Follows the logic from avr32.

Move rcu-protected lists from list.h into a new header file rculist.h.
This is done because list are a very used primitive structure all over the
kernel and it's currently impossible to include other header files in this
list.h without creating some circular dependencies.
For example, list.h implements rcu-protected list and uses rcu_dereference()
without including rcupdate.h. It actually compiles because users of
rcu_dereference() are macros. Others RCU functions could be used too but
aren't probably because of this.
Therefore this patch creates rculist.h which includes rcupdates without to
many changes/troubles.

Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.
This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.) However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.
This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.

x86: disable mwait for AMD family 10H/11H CPUs
x86: fix crash on cpu hotplug on pat-incapable machines
x86: remove mwait capability C-state check
The previous revert of 0c07ee38c9 left
out the mwait disable condition for AMD family 10H/11H CPUs.
Andreas Herrman said:
It depends on the CPU. For AMD CPUs that support MWAIT this is wrong.
Family 0x10 and 0x11 CPUs will enter C1 on HLT. Powersavings then
depend on a clock divisor and current Pstate of the core.
If all cores of a processor are in halt state (C1) the processor can
enter the C1E (C1 enhanced) state. If mwait is used this will never
happen.
Thus HLT saves more power than MWAIT here.
It might be best to switch off the mwait flag for these AMD CPU
families like it was introduced with commit
f039b75471 (x86: Don't use MWAIT on AMD
Family 10)
Re-add the AMD families 10H/11H check and disable the mwait usage for
those.
