6a0641e510 [POWERPC] spufs: state_mutex cleanup
Various cleanups in code surrounding the state semaphore:

 - inline spu_acquire/spu_release
 - cleanup spu_acquire_* and add kerneldoc comments to these functions
 - remove spu_release_exclusive and replace it with spu_release

650f8b0291 [POWERPC] spufs: simplify state_mutex
The r/w semaphore to lock the spus was overkill and can be replaced
with a mutex to make it faster, simpler and easier to debug.  It also
helps to allow making most spufs interruptible in future patches.

202557d29e [POWERPC] spufs: sched.c cleanups
Various cleanups to sched.c that don't change the global control flow:

 - add kerneldoc comments to various functions
 - add spu_ prefixes to various functions
 - add/remove context from the runqueue in bind/unbind_context as
   it's part of the logical operation
 - add a call to put_active_spu to spu_unbind_contex as it's logically
   part of the unbind operation

81998bafe2 [POWERPC] spufs: bind_context sets SPU_STATE_RUNNABLE
Only bind_context/unbind_context change the spu context state.  Thus
we can move all assignents of SPU_STATE_RUNNABLE into bind_context,
which parallels the unbind side aswell.

17e0e27020 [POWERPC] spufs: Fix bitrot of the SPU mmap facility
It looks like we've had some serious bitrot there mostly due to tracking
of address_space's of mmap'ed files getting out of sync with the actual
mmap code. The mfc, mss and psmap were not tracked properly and thus
not invalidated on context switches (oops !)

I also removed the various file->f_mapping = inode->i_mapping;
assignments that were done in the other open() routines since that
is already done for us by __dentry_open.

One improvement we might want to do later is to assign the various
ctx-> fields at mmap time instead of file open/close time so that we
don't call unmap_mapping_range() on thing that have not been mmap'ed

Finally, I added some smp_wmb's after assigning the ctx-> fields to make
sure they are visible to other CPUs. I don't think this is really
necessary as I suspect locking in the fs layer will make that happen
anyway but better safe than sorry.

78bde53e35 [POWERPC] spufs: remove need for struct page for SPEs
This patch removes the need for struct page for SPE local store
and registers from spufs. It also makes the locking much more
obvious and no longer relying on the truncate logic black magic
for protecting against races between unmap_mapping_range() and
new pages faulted in. It does so by switching to a nopfn() handler
and using the new vm_insert_pfn() to setup the PTEs itself while
holding a lock on the SPE.

The nice thing is that this patch actually removes a lot more code
than it adds :-)

9724b86f07 [POWERPC] Small cleanup of EFIKA platform
The efika platform used three files efika-pci.c efika-setup.c and
a 2 line efika.h to link the two. The total of code in those is
really not much and therefore, I think they're better merged
in a single file.

There is absolutely _no_code_change_ at all, just merged the files.

  - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the

  - The early boot parameter `ps3fb=xxx' allows to override the default value.
    It will be rounded up to a multiple of 1 MiB, if needed.

Don't guess. Also extend linkstation_defconfig to support the linkstation HS
model with a IT8212 IDE controller and kuroboxHD/HD-HLAN linkstation
models with a tulip ethernet chip. The latter also require a slightly
different .dts file, which is also included with this patch.

The previous patch changing pSeries to use H_BULK_REMOVE broke the

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.

- Added 82xx subdir to the powerpc/platforms Makefile, missed during

- new solely-powerpc header file for 8260 family (was using one from
  arch/ppc, this one cleaned up from the extra stuff), in fact for now
  a placeholder to get the board-specific includes for stuff not yet

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.

c75f902b93 [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.

77319254f1 [POWERPC] Fix broken DMA on non-LPAR pSeries
It appears that the iommu table address is never stored, and thus
never found, on non-lpar systems. Thus, for example, during boot:

<7>[   93.067916] PCI: Scanning bus 0001:41
<7>[   93.068542] PCI: Found 0001:41:01.0 [8086/100f] 000200 00
<7>[   93.068550] PCI: Calling quirk c0000000007822e0 for 0001:41:01.0
<7>[   93.069815] PCI: Fixups for bus 0001:41
<4>[   93.070167] iommu: Device 0001:41:01.0 has no iommu table
<7>[   93.070251] PCI: Bus scan for 0001:41 returning with max=41

No iommu table? How can that be? Well, circa line 471 of
arch/powerpc/platforms/pseries/iommu.c we see the code:

   while (dn && PCI_DN(dn) && PCI_DN(dn)->iommu_table == NULL)
      dn = dn->parent;

and a few lines later is the surprising print statement about
the missing table.  Seems that this loop ran unto the end, never
once finding a non-null PCI_DN(dn)->iommu_table.

The problem can be found a few lines earlier: it sems that the
value of PCI_DN(dn)->iommu_table is never ever set. Thus, the
patch sets it.

The patch was tested on a Power4 system running in full system
partition mode, which is where I saw the problem. It works; I've
not done any wider testing. Had a brief discussion on this on irc.

dc40127ca5 [POWERPC] Fix bugs in the hypervisor call stats code
There were a few issues with the HCALL_STATS code:

- PURR cpu feature checks were backwards
- We iterated one entry off the end of the hcall_stats array
- Remove dead update_hcall_stats() function prototype

I noticed one thing while debugging, and that is we call H_ENTER (to set
up the MMU hashtable in early init) before we have done the cpu fixups.
This means we will execute the PURR SPR reads even on a CPU that isnt
capable of it. I wonder if we can move the CPU feature fixups earlier.

a223535425 [POWERPC] dont allow pSeries_probe to succeed without initialising MMU
pSeries_probe can decide that we are a pseries but then fail to
initialise the MMU. If an rtas node doesnt exist, we continually fall
out of pSeries_probe_hypertas early and never get to the MMU init code.

While pseries without RTAS is an illegal combination, the way we
currently fail is a pain to track down, and can happen if your flattened
device tree code has issues (like mine did :).

With the following patch we init the MMU, come up and print some
warnings about RTAS not existing, instead of looping on 0x400 exceptions.

04da6af960 [POWERPC] Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c
Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c,
this allows rtas_stop_self() to be static so remove the prototype.

Wire up pSeries_mach_cpu_die() in the initcall, rather than statically
in setup.c, the initcall will still run prior to the cpu hotplug code
being callable, so there should be no change in behaviour.

a5715d6dfc [POWERPC] pSeries/kexec: Fix for interrupt distribution
This allows any secondary CPU thread also to become boot cpu for
POWER5.  The patch is required to solve kdump boot issue when the
kdump kernel is booted with parameter "maxcpus=1".  XICS init code
tries to match the current boot cpu id with "reg" property in each CPU
node in the device tree.  But CPU node is created only for primary
thread CPU ids and "reg" property only reflects primary CPU ids.  So
when a kernel is booted on a secondary cpu thread above condition will
never meet and the default distribution server is left as zero.  This
leads to route the interrupts to CPU 0, but which is not online at
this time.

We use ibm,ppc-interrupt-server#s to check for both primary and
secondary CPU ids.  Accordingly default distribution server value is
initialized from "ibm,ppc-interrupt-gserver#s" property.  We loop
through ibm,ppc-interrupt-gserver#s property to find the global
distribution server from the last entry that matches with boot cpuid.

e22ba7e381 [POWERPC] ps3: multiplatform build fixes
A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.
