The longrun cpufreq module reports a false minimum frequency 3MHz on
300-600MHz Crusoe processor. This may be due to a calculation bug
in the module.

The most common error with powernow-k8 is an ACPI _PSS error
caused either by failure to load the ACPI processor module
or a bad parse of the _PSS object. Make the error message
returned to the user in these situations more straightforward
and easier to understand.

Compiling ppc64_defconfig with gcc 4.3 gives thes warnings:
arch/powerpc/sysdev/mpic.c: In function 'mpic_irq_get_priority':
arch/powerpc/sysdev/mpic.c:1351: warning: 'is_ipi' may be used uninitialized in this function
arch/powerpc/sysdev/mpic.c: In function 'mpic_irq_set_priority':
arch/powerpc/sysdev/mpic.c:1328: warning: 'is_ipi' may be used uninitialized in this function
It turns out that in the cases where is_ipi is uninitialized, another
variable (mpic) will be NULL and it is dereferenced. Protect against
this by returning if mpic is NULL in mpic_irq_set_priority, and removing
mpic_irq_get_priority completely as it has no in tree callers.
This has the nice side effect of making the warning go away.

Since commit "85xx: Add support for relocatable kernel (and
booting at non-zero)" (37dd2badcfcec35f5e21a0926968d77a404f03c3),
PHYSICAL_START is #defined as kernstart_addr if RELOCATABLE
and FLATMEM is enabled.
PHYSICAL_START is used in prom_init.c and so kernstart_addr
needs to be added to the list of allowed symbols that
prom_init.c can access.

A change was made to walk_memory_resource() in commit
4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a
check of find_lmb(). Add the coresponding lmb_add()
call to ps3_mm_add_memory() so that that check will
succeed.
This fixes the condition where the PS3 boots up with
only the 128 MiB of boot memory, and doesn't see the
other 128MiB that is available.

The offset to the pt_regs area was wrong, so we weren't
looking at the right location for the magic cookie.
A trap frame is composed of a "struct sparc_stackf" then
a "struct pt_regs", the code was using "struct reg_window"
instead of "struct sparc_stackf".

Because of the silly way I set up the initial stack for
new kernel threads, there is a loop at the top of the
stack.
To fix this, properly add another stack frame that is copied
from the parent and terminate it in the child by setting
the frame pointer in that frame to zero.

When a cpu really is stuck in the kernel, it can be often
impossible to figure out which cpu is stuck where. The
worst case is when the stuck cpu has interrupts disabled.
Therefore, implement a global cpu state capture that uses
SMP message interrupts which are not disabled by the
normal IRQ enable/disable APIs of the kernel.
As long as we can get a sysrq 'y' to the kernel, we can
get a dump. Even if the console interrupt cpu is wedged,
we can trigger it from userspace using /proc/sysrq-trigger
The output is made compact so that this facility is more
useful on high cpu count systems, which is where this
facility will likely find itself the most useful :)

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.

FSVOtest in this case, since I don't have the hardware...
However, all changes seen by gcc are actually
- explicit cast to unsigned short in return expression of functions
returning unsigned short
- csum_fold() return type changed from unsigned int to __sum16
(unsigned short), same as for all other architecture and as net/* expects;
expression actually returned is ((~(sum << 16)) >> 16) with sum being
unsigned 32bit, so it's (a) going to fit into the range of unsigned short
and (b) had been unsigned all along, so no sign expansion mess happened.

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.
