Pull powerpc fixes from Ben Herrenschmidt:
"Here is not quite a handful of powerpc fixes for rc3.
The windfarm fix is a regression fix (though not a new one), the PMU
interrupt rename is not a fix per-se but has been submitted a long
time ago and I kept forgetting to put it in (it puts us back in sync
with x86), the other perf bit is just about putting an API/ABI bit
definition in the right place for userspace to consume, and finally,
we have a fix for the VPHN (Virtual Partition Home Node) feature
(notification that the hypervisor is moving nodes around) which could
cause lockups so we may as well fix it now"

Pull parisc updates from Helge Deller:
"The majority of lines changed are due the addition of a defconfig for
the C8000 machine. Even the fix in parisc/kernel/cache.c file is
actually ony a 10-line fix, but the change became bigger (and much

Here is the short-changelog:
This round of parisc updates includes mostly fixes for the C8000
workstation. We have a new defconfig file for this machine, as well
as fixes for it's serial port, the AGP driver and the cache routines
to cope with the vmas of the FireGL card in a C8000. The sys32.h

Pull ACPI and power management fixes from Rafael Wysocki:
- Revert two cpuidle commits added during the 3.8 development cycle
that turn out to have introduced a significant performance regression
as requested by Jeremy Eder.
- The recent patches that made the freezer less heavy-weight introduced
a regression causing user-space-driven hibernation using the ioctl()
interface to block indefinitely when the hibernate process executes
try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.
- One of the recent cpufreq reverts uncovered a problem in the core
causing the cpufreq driver module refcount to become negative after a
system suspend-resume cycle. Fix from Rafael J Wysocki.
- The evaluation of the ACPI battery _BIX method has never worked
correctly, because the commit that added support for it forgot to
take the "Revision" field in the return package into account. As a
result, the reading of battery info doesn't work at all on some
systems, which is addressed by a fix from Lan Tianyu.

This patch does the initial bonding conversion to RCU. After it the
following modes are protected by RCU alone: roundrobin, active-backup,
broadcast and xor. Modes ALB/TLB and 3ad still acquire bond->lock for
reading, and will be dealt with later. curr_active_slave needs to be
dereferenced via rcu in the converted modes because the only thing
protecting the slave after this patch is rcu_read_lock, so we need the
proper barrier for weakly ordered archs and to make sure we don't have
stale pointer. It's not tagged with __rcu yet because there's still work
to be done to remove the curr_slave_lock, so sparse will complain when
rcu_assign_pointer and rcu_dereference are used, but the alternative to use
rcu_dereference_protected would've created much bigger code churn which is
more difficult to test and review. That will be converted in time.
1. Active-backup mode
1.1 Perf recording while doing iperf -P 4
- old bonding: iperf spent 0.55% in bonding, system spent 0.29% CPU
in bonding
- new bonding: iperf spent 0.29% in bonding, system spent 0.15% CPU
in bonding
1.2. Bandwidth measurements
- old bonding: 16.1 gbps consistently
- new bonding: 17.5 gbps consistently
2. Round-robin mode
2.1 Perf recording while doing iperf -P 4
- old bonding: iperf spent 0.51% in bonding, system spent 0.24% CPU
in bonding
- new bonding: iperf spent 0.16% in bonding, system spent 0.11% CPU
in bonding
2.2 Bandwidth measurements
- old bonding: 8 gbps (variable due to packet reorderings)
- new bonding: 10 gbps (variable due to packet reorderings)
Of course the latency has improved in all converted modes, and moreover
while
doing enslave/release (since it doesn't affect tx anymore).
Also I've stress tested all modes doing enslave/release in a loop while
transmitting traffic.

I factored out the tx xmit code which relies on slave id in
bond_xmit_slave_id. It is global because later it can be used also in
3ad mode xmit. Unnecessary obvious comments are removed. Active-backup
mode is simplified because bond_dev_queue_xmit always consumes the skb.
bond_xmit_xor becomes one line because of bond_xmit_slave_id.
bond_for_each_slave_from is not used in bond_xmit_slave_id because later
when RCU is used we can avoid important race condition by using standard
rculist routines.

We don't need to start from the curr_active_slave as the frame will be
sent to all eligible slaves anyway, so we remove the unnecessary local
variables, checks and comments, and make it use the standard list API.
This has the nice side-effect that later when it's converted to RCU
a race condition will be avoided which could lead to double packet tx.

In all the cases we already hold bond->lock for reading, so the slave
can't get away and the check != NULL is sufficient. curr_active_slave
can still change after the read_lock is unlocked prior to use of the
dereferenced value, so there's no need for it. It either contains a
valid slave which we use (and can't get away), or it is NULL which is
checked.
In some places the read_lock of curr_slave_lock was left because we need
it not to change while performing some action (e.g. syncing current
active slave's addresses, sending ARP requests through the active slave)
such cases will be dealt with individually while converting to RCU.

This patch aims to remove struct bonding's first_slave and struct
slave's next and prev pointers, and replace them with the standard Linux
list API. The old macros are converted to list API as well and some new
primitives are available now. The checks if there're slaves that used
slave_cnt have been replaced by the list_empty macro.
Also a few small style fixes, changing longest -> shortest line in local
variable declarations, leaving an empty line before return and removing
unnecessary brackets.
This is the first step to gradual RCU conversion.

On very rare occasions, repeated load/unload stress test in the presence of
our storage driver (bnx2i/bnx2fc) causes a kernel panic in bnx2x code
(NULL pointer dereference). Stack traces indicate the issue happens during MAC
configuration; thorough code review showed that indeed several races exist
in which one thread can iterate over the list of configured MACs while another
deletes entries from the same list.
This patch adds a varient on the single-writer/Multiple-reader lock mechanism -
It utilizes an already exsiting bottom-half lock, using it so that Whenever
a writer is unable to continue due to the existence of another writer/reader,
it pends its request for future deliverance.
The writer / last readers will check for the existence of such requests and
perform them instead of the original initiator.
This prevents the writer from having to sleep while waiting for the lock
to be accessible, which might cause deadlocks given the locks already
held by the writer.
Another result of this patch is that setting of Rx Mode is now made in
sleepable context - Setting of Rx Mode is made under a bottom-half lock, which
was always nontrivial for the bnx2x driver, as the HW/FW configuration requires
wait for completions.
Since sleep was impossible (due to the sleepless-context), various mechanisms
were utilized to prevent the calling thread from sleep, but the truth was that
when the caller thread (i.e, the one calling ndo_set_rx_mode()) returned, the
Rx mode was still not set in HW/FW.
bnx2x_set_rx_mode() will now overtly schedule for the Rx changes to be
configured by the sp_rtnl_task which hold the RTNL lock and is sleepable
context.

After commit 4aa5dee4d9 ("net: convert resend IGMP to notifier event")
we try to acquire rtnl in bond_resend_igmp_join_requests but it can be
scheduled with rtnl already held (e.g. when bond_change_active_slave is
called with rtnl) causing a loop of immediate reschedules + calls because
rtnl_trylock fails each time since it's being already held.
For me this issue leads to system hangs very easy:
modprobe bonding; ifconfig bond0 up; ifenslave bond0 eth0; rmmod
bonding;
The fix is to introduce a small (1 jiffy) delay which is enough for the
sections holding rtnl to finish without putting any strain on the system.
Also adjust the timer in bond_change_active_slave to be 1 jiffy, since
most of the time it's called with rtnl already held.

The code used to call napi_disable() in an interrupt handler
(from smp_call_function), which in turn could call msleep().
Unfortunately you can't sleep in an interrupt context.
Luckily it turns out all the NAPI support functions are
just operating on data structures and not on any deeply
per-cpu data, so we can arrange to set up and tear down all
the NAPI state on the core driving the process, and just
do the IRQ enable/disable as a smp_call_function thing.

The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able
to dynamically set up MBus address decoding windows for PCI I/O and
memory regions depending on the PCI devices enumerated by Linux.
However, this emulated PCI-to-PCI bridge logic makes the Linux PCI
core believe that prefetchable memory regions are supported (because
the registers are read/write), while in fact no adress decoding window
is ever created for such regions. Since the Marvell MBus address
decoding windows do not distinguish memory regions and prefetchable
memory regions, this patch takes a simple approach: change the
PCI-to-PCI bridge emulation to let the Linux PCI core know that we
don't support prefetchable memory regions.
To achieve this, we simply make the prefetchable memory base a
read-only register that always returns 0. Reading/writing all the
other prefetchable memory related registers has no effect.
This problem was originally reported by Finn Hoffmann
<finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working
on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem
was that the PCI-to-PCI bridge emulation was making the Linux PCI core
believe that we support prefetchable memory, so the Linux PCI core was
only filling the prefetchable memory base and limit registers, which
does not lead to a MBus window being created. The below patch has been
confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has
otherwise been successfully tested on the Armada XP GP platform with a
e1000e PCIe NIC and a Marvell SATA PCIe card.

parameters are incorrect, and have been copied from the Drive Bay fan

changes the parameters to match the Slots fan (PWM) of therm_pm72. With

Self explanitory dma_mapping_error addition to the 8139 driver, based on this:
https://bugzilla.redhat.com/show_bug.cgi?id=947250
It showed several backtraces arising for dma_map_* usage without checking the
return code on the mapping. Add the check and abort the rx/tx operation if its
failed. Untested as I have no hardware and the reporter has wandered off, but
seems pretty straightforward.

The RFE interrupt is enabled for the r8a7790 but isn't handled,
resulting in the interrupts core noticing unhandled interrupts, and
eventually disabling the ethernet IRQ.
Fix it by adding RFE to the bitmask of error interrupts to be handled
for r8a7790.
