This did corrupt register s0 which the caller of self_ipi expects to

the compilers which compile __smtc_ipi_replay to use s0 across the

Bob Picco 12710a56cb fix sysrq-m oops
We aren't sampling for holes in memory.  Thus we encounter a section hole
with empty section map pointer for SPARSEMEM and OOPs for show_mem.  This
issue has been seen in 2.6.21, current git and current mm.  The patch below
is for mainline and mm.  It was boot tested for SPARSEMEM, current VMEMMAP
of Andy's in mm ml and DISCONTIGMEM.  A slightly different patch will be
posted to stable for 2.6.21.

Previous to commit f0a5a58aa8 memory_present
was called for node_start_pfn to node_end_pfn.  This would cover the
hole(s) with reserved pages and valid sections.  Most SPARSEMEM supported
arches do a pfn_valid check in show_mem before computing the page structure
address.

This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo.
Thanks to Arnaldo for testing.

David S. Miller 8c2786cfa6 [SPARC64]: Handle PCI bridges without 'ranges' property.
This fixes the IDE controller not showing up on Netra-T1
systems.

Just like Simba bridges, some PCI bridges can lack the
'ranges' OBP property.  So we handle this similarly to
the existing Simba code:

1) In of_device register address resolving, we push the
   translation to the parent.

2) In PCI device scanning, we interrogate the PCI config
   space registers of the PCI bus device in order to resolve
   the resources, just like the generic Linux PCI probing
   code does.

With much help and testing from Fabio, who also reported
the initial problem.

Steven Rostedt e5e3c84b70 enable interrupts in user path of page fault.
This is a minor fix, but what is currently there is essentially wrong.
In do_page_fault, if the faulting address from user code happens to be
in kernel address space (int *p = (int*)-1; p = 0xbed;)  then the
do_page_fault handler will jump over the local_irq_enable with the

  goto bad_area_nosemaphore;

But the first line there sees this is user code and goes through the
process of sending a signal to send SIGSEGV to the user task. This whole
time interrupts are disabled and the task can not be preempted by a
higher priority task.

This patch always enables interrupts in the user path of the
bad_area_nosemaphore.

David S. Miller ec4d18f219 [SPARC64]: Fix SBUS IRQ regression caused by PCI-E driver.
We used to access the 64-bit IRQ IMAP and ICLR registers of bus
controllers 4-bytes in and as a 32-bit register word, since only the
low 32-bits were relevant.  This seemed like a good idea at the time.

But the PCI-E controller requires full 8-byte 64-bit access to
these registers, so we switched over to accessing them fully.

SBUS was not adjusted properly, which broke interrupts completely.

Arnd Bergmann e7c40012b8 [POWERPC] Fix pci_setup_phb_io_dynamic for pci_iomap
We had a problem on a system with only dynamically allocated
PCI buses (using of_pci_phb_driver) in combination with libata.
This setup ended up having no "primary" phb, which means
that pci_io_base never got initialized and all IO port
numbers are 64 bit numbers, which is larger than the
PIO_MASK limit.

Christoph Hellwig bb5db29aa0 [POWERPC] spufs scheduler: Fix wakeup races
Fix the race between checking for contexts on the runqueue and actually
waking them in spu_deactive and spu_yield.

The guts of spu_reschedule are split into a new helper called
grab_runnable_context which shows if there is a runnable thread below
a specified priority and if yes removes if from the runqueue and uses
it.  This function is used by the new __spu_deactivate hepler shared
by preemption and spu_yield to grab a new context before deactivating
a specified priority and if yes removes if from the runqueue and uses
it.  This function is used by the new __spu_deactivate hepler shared
by preemption and spu_yield to grab a new context before deactivating
the old one.
