394e3902c5 [PATCH] more for_each_cpu() conversions
When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all.  The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().

This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
few instances of this bug, if any.  But the patch converts lots of open-coded
test to use the preferred helper macros.

7835e98b2e [PATCH] remove set_page_count() outside mm/
set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().

This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.

260de22faa [PATCH] powerpc: iseries: mf related cleanups
Some cleanups in the iSeries code.
 - Make mf_display_progress() check mf_initialized rather than the caller.
 - Set mf_initialized in mf_init() rather than in setup.c
 - Then move mf_initialized into mf.c, the only place it's used.
 - Move the mf related logic from iSeries_progress() to mf_display_progress()
 - Use a #define to size the pending_event_prealloc array
 - Use that define in the initialsation loop rather than sizeof jiggery pokery
 - Remove stupid comment(s)
 - Mark stuff static and/or __init

57cfb814f6 [PATCH] powerpc: Replace platform_is_lpar() with a firmware feature
It has been decreed that platform numbers are evil, so as a step in that
direction, replace platform_is_lpar() with a FW_FEATURE_LPAR bit.

Currently FW_FEATURE_LPAR really means i/pSeries LPAR, in the future we might
have to clean that up if we need to be more specific about what LPAR actually
means. But that's another patch ...

The dynamic add path for PCI Host Bridges can fail to configure children

need to occur before any children devices are enabled in

The lparcfg code needs several things which are pretty arcane internal
details and which we don't want to export, which means that lparcfg
doesn't work when built as a module.  This makes it a bool instead of
a tristate in the Kconfig so that users can't try to build it as a

0c2aca88bd powerpc32: Fix timebase synchronization on 32-bit powermacs
The variable `timebase' used to transfer the current timebase value
from one cpu to the other in smp_core99_give/take_timebase was only
an unsigned long, i.e. 32 bits on 32-bit machines.  It needs to be
64 bits.  This makes it a u64, and fixes the issue reported by Kyle
Moffett, that the two cpus see wildly different values for the time
of day.

827c1a6c1a [PATCH] powerpc: fix dynamic PCI probe regression
Some hotplug driver functions were migrated to the kernel for use by EEH
in commit 2bf6a8fa21.

Previously, the PCI Hotplug module had been changed to use the new
OFDT-based PCI probe when appropriate:
5fa80fcdca

When rpaphp_pci_config_slot() was moved from the rpaphp driver to the
new kernel function pcibios_add_pci_devices(), the OFDT-based probe
stuff was dropped.  This patch restores it.

cb2c9b2741 [PATCH] powerpc: Fix runlatch performance issues
The runlatch SPR can take a lot of time to write. My original runlatch
code would set it on every exception entry even though most of the time
this was not required. It would also continually set it in the idle
loop, which is an issue on an SMT capable processor.

Now we cache the runlatch value in a threadinfo bit, and only check for
it in decrementer and hardware interrupt exceptions as well as the idle
loop. Boot on POWER3, POWER5 and iseries, and compile tested on pmac32.

c8b8b1f2e0 [PATCH] powermac: Fix loss of ethernet PHY on sleep
Some recent PowerBook models tend to lose the ethernet PHY on
suspend/resume.  It -seems- that they use a combo ethernet-firewire PHY
chip and the firewire PHY seems to die the same way when that happens.  Not
trying to toggle the firewire cable power appears to fix it.  So this patch
disables changes to the firewire cable power control GPIO on those models.

496b7a5159 [PATCH] powerpc: Fix bug in spinup of renumbered secondary threads
If the logical and physical cpu ids of a secondary thread don't match, we will
fail to spin the thread up on pSeries machines due to a bug in pseries/smp.c

We call the RTAS "start-cpu" method with the physical cpu id, the address of
pSeries_secondary_smp_init and the value to pass that function in r3. Currently
we pass "lcpu", the logical cpu id, but pSeries_secondary_smp_init expects
the physical cpu id in r3.

We should be passing pcpu instead.

40727198bf [SUNGEM]: Make PM of PHYs more reliable (#2)
On my latest laptop, I've had occasional PHY dead on wakeup from
sleep... the PHY would be totally unresponsive even to toggling the hard
reset line until the machine is powered down... Looking closely at the
code, I found some possible issues in the way we setup the MDIO lines
during suspend along with slight divergences from what Darwin does when
resetting it that may explain the problem. That patch change these and
the problem appear to be gone for me at least... I also fixed an mdelay
-> msleep while I was at it to the pmac feature code that is called
when toggling the PHY reset line since sungem doesn't call it in an
atomic context anymore.

3356bb9f7b [PATCH] powerpc: Remove lppaca structure from the PACA
At present the lppaca - the structure shared with the iSeries
hypervisor and phyp - is contained within the PACA, our own low-level
per-cpu structure.  This doesn't have to be so, the patch below
removes it, making a separate array of lppaca structures.

This saves approximately 500*NR_CPUS bytes of image size and kernel
memory, because we don't need aligning gap between the Linux and
hypervisor portions of every PACA.  On the other hand it means an
extra level of dereference in many accesses to the lppaca.

The patch also gets rid of several places where we assign the paca
address to a local variable for no particular reason.

7f52eb0093 [PATCH] spufs: Suspend/restore MFC DMA operations at SPU context switch.
The SPE Book IV indicates that MFC DMA operations must be
suspended and restored on SPU context switch (in Step 8).

This patch adds that operation, which is missing from the
current spufs implementation.

296167ae17 [PATCH] powerpc: Make early debugging configurable via Kconfig
This patch adds Kconfig entries to control the early debugging options,
currently in setup_64.c.

Doing this via Kconfig rather than #defines means you can have one source tree,
which is buildable for multiple platforms - and you can enable the correct
early debug option for each platform via .config.

I made udbg_early_init() a static inline because otherwise GCC is to daft to
optimise it away when debugging is off.

Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.

bf6a7112bd [PATCH] powerpc: Early debugging support for iSeries
Connect iSeries up to the standard early debugging infrastructure.

To actually use this you need to enable the iSeries early debugging
in setup_64.c. Then after the messages are logged hit Ctrl-x Ctrl-x on
your console to dump the Hypervisor console buffer.

13b8a27229 powerpc: Introduce a new config symbol to control 16550 early debug code
The previous change by Kumar Gala in this area led to legacy_serial.c
and udbg_16550.c being built as modules when CONFIG_SERIAL_8250=m.
Fix this by introducing a new symbol, CONFIG_PPC_UDBG_16550, to
control whether these files get built, and arrange for it to be selected
for those platforms that need it.

257ffc64a6 [PATCH] powerpc: get rid of per_cpu EEH counters
242-eeh-no-percpu-counters.patch

Remove per-cpu counters from the EEH code.  These statistics counters
are incremented at a very low frequency, and the performance gains of
per-cpu variables are negligable.  By contrast, the counters weren't
safe against cpu off/online operations, and its not worth the effort
to make them so (other than to turn them into plain globals).

3914ac7b0e [PATCH] powerpc: handle multifunction PCI devices properly
239-eeh-multifunction-consolidate.patch

New-style firmware will often place multiple different functions
under a non-EEH-aware parent.  However, these devices might share
a common PE "partition endpoint" and config address, ad thus any
EEH events will affect all of the devices in common.  This patch
makes the effort to find all of these common devices and handle
them together.
