12e86f92fc [POWERPC] Only use H_BULK_REMOVE if the firmware supports it
The previous patch changing pSeries to use H_BULK_REMOVE broke the
JS20 blade, where the firmware doesn't support H_BULK_REMOVE.  This
adds a firmware check so that on machines that don't have H_BULK_REMOVE,
we just use the H_REMOVE call as before.

f7feaca77d msi: Make MSI useable more architectures
The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.

arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.

With this change in place this code should be useable by all platforms
except those that won't let the OS touch the hardware like ppc RTAS.

5b912c108c msi: Kill the msi_desc array.
We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c.  Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.

So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.

The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.

5fad293bcb [POWERPC] Fixup error handling when emulating a floating point instruction
When we do full FP emulation its possible that we need to post a SIGFPE based
on the results of the emulation.  The previous code ignored this case completely.

Additionally, the Soft_emulate_8xx case had two issues.  One, we should never
generate a SIGFPE since the code only does data movement.  Second, we were
interpreting the return codes incorrectly, it returns 0 on success, 1 on
illop and -EFAULT on a data access error.

04903a30a3 [POWERPC] Enable interrupts if we are doing fp math emulation
Anytime we are emulating an instruction we are going to be doing some form of
get_user() to get the instruction image to decode.  Since get_user() might
sleep we need to ensure we have interrupts enabled or we might see something
like:

Debug: sleeping function called from invalid context at arch/powerpc/kernel/traps.c:697
in_atomic():0, irqs_disabled():1
Call Trace:
[D6023EB0] [C0007F84] show_stack+0x58/0x174 (unreliable)

--- Exception: 700 at 0x102a7100
    LR = 0xdb9ef04

However, we want to ensure that interrupts are disabled when handling a trap
exception that might be used for a kernel breakpoint.  This is why ProgramCheck
is marked as EXC_XFER_STD instead of EXC_XFER_EE.

e56a6e20f3 [POWERPC] Clear RI bit in MSR before restoring r13 when returning to userspace
Some instruction tracing tools use the RI (recoverable interrupt) bit
in the MSR to indicate when it's safe to single-step.  Currently we
clear RI after restoring r13 when returning to userspace.  However,
if we single-step past the point where r13 is restored, we'll corrupt
r13 in the exception entry code and not restore it.  This moves the
clearing of RI to just before r13 is restored so this doesn't happen.

449d846dbc [POWERPC] Fix performance monitor exception
To the issue: some point during 2.6.20 development, Paul Mackerras
introduced the "lazy IRQ  disabling" patch (very cool work,  BTW).
In that patch, the performance monitor unit exception was marked as
"maskable", in the sense that if interrupts were soft-disabled, that
exception could be ignored.  This broke my PowerPC profiling code.
The symptom that I see is that a varying number of interrupts
(from 0 to $n$, typically closer to 0) get delivered, when, in
reality, it should always be very close to $n$.

The issue stems from the way masking is being done.   Masking in
this fashion seems to  work well with the decrementer and external
interrupts, because they are raised again until "really"  handled.
For the PMU, however, this does not apply (at least on my Xserver
machine with a 970FX processor).  If the PMU exception is not handled,
it will _not_ be re-raised (at least on my machine).  The documentation
states that the PMXE bit in MMCR0 is set to 0 when the PMU exception
is raised.  However, software must re-set the bit to re-enable PMU
exceptions.  If the exception is ignored (as currently) not only is
that interrupt lost, but because software does not re-set PMXE, the
PMU registers are "frozen" forever.

[This patch means that performance monitor exceptions are taken and
handled even if irqs are off, as long as some other interrupt hasn't
come along and caused interrupts to be hard-disabled.  In this sense
the PMU exception becomes like an NMI.  The oprofile code for most
powerpc processors does nothing that is unsafe in an NMI context, but
the Cell oprofile code does a spin_lock_irqsave.  However, that turns
out to be OK because Cell doesn't actually use the performance
monitor exception; performance monitor interrupts come in as a
regular interrupt on Cell, so will be disabled when irqs are off.

f9fba5b72d [POWERPC] pasemi: Configure DMA controller interrupts
The DMA controller on PWRficient is somewhat special -- has a PCI header
so it looks like it's on the root PCI (-Express) root bus, but it uses
more than the default number of interrupts (and they are hardwired).

We need to wire up all interrupts for the DMA controller. The generic
IRQ code will only map the primary interrupt from the PCI header (128),
so add 129->211 by hand.

4942bd80e8 [POWERPC] Fix array indexing error in rheap grow()
The grow() function in the rheap library allocates a larger array of blocks,
copies the contents of the old blocks array to the newly allocated array and
fixes the list_head pointers after the copy.  At the end, the new blocks must
be enqueued to the empty_list of the rh_info_t structure.  This patch fixes
a bug where the code was indexing past the end of the array when enqueueing
blocks.  The UCC ethernet driver, which uses the rheap allocator, experiences
kernel panics because of this bug.

25c4a46f0e [POWERPC] pSeries: EEH improperly enabled for some Power4 systems
It appears that EEH is improperly enabled for some Power4 systems.
On these systems, the ibm,set-eeh-option returns a value of success
even when EEH is not supported on the given node. Thus, an explicit
check for support is required.

During boot, on power4, without this patch, one sees messages
similar to:

EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2
etc.

The patch makes these go away.

Without this patch, EEH recovery does seem to work correctly for
at least some devices (I tested ethernet e1000), but fails to
recover others (the Emulex LightPulse LPFC, most notably).
Off the top of my head, I don't remember why some devices are
affected, but not others.

The PAPR indicates that the correct way to test for EEH is as
done in this patch; its not clear to me if this was in the PAPR
all along, or recently added; if it was there all along, its not
clear to me why this hadn't been fixed long ago. I suspect only
certain firmware levels are affected.

4a969e1e22 [MIPS] Remove superfluous "ifdef CONFIG_KGDB".
Given that the Makefiles involved already have conditional compilation of
 the form:

  obj-$(CONFIG_KGDB)      += dbg_io.o

there seems to be little value for the dbg_io.c source files to check
that config variable yet again.
