[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.

17 years ago[POWERPC] Fix performance monitor exception
Livio Soares [Wed, 7 Feb 2007 01:51:36 +0000 (12:51 +1100)]
[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.

[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.

[POWERPC] 83xx: Return a point to the struct ipic from ipic_init()

It's useful to have access to struct ipic handle that just got created
in ipic_init().

For example, if we want to setup an external IRQ with out
a device node we need access ipic->irqhost to create the virtual to HW
IRQ mapping and to set the IRQ sense.  With this we can mimic the old
sense array concept that existed in arch/ppc.

[POWERPC] 83xx: Don't call ioremap in the reset function

It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler).  Therefor, we can't call
ioremap in the reset function.  Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.

However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called.  If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.
