Fix up conflicts in fs/nfsd/vfs.c with the vfs-scale work.  The
vfs-scale work touched some msnfs cases, and this merge removes support
for that entirely, so the conflict was trivial to resolve.

0ad53eeefc afs: add afs_wq and use it instead of the system workqueue
flush_scheduled_work() is going away.  afs needs to make sure all the
works it has queued have finished before being unloaded and there can
be arbitrary number of pending works.  Add afs_wq and use it as the
flush domain instead of the system workqueue.

Also, convert cancel_delayed_work() + flush_scheduled_work() to
cancel_delayed_work_sync() in afs_mntpt_kill_timer().

ff29530e65 PCI: sysfs: Update ROM to include default owner write access
The PCI sysfs ROM interface requires an enabling write to access the ROM
image, but the default file mode is 0400.  The original proposed patch
adding sysfs ROM support was a true read-only interface, with the
enabling bit coming in as a feature request.  I suspect it was simply an
oversight that the file mode didn't get updated to match the API.

64a5fed666 x86/PCI: make Broadcom CNB20LE driver EMBEDDED and EXPERIMENTAL
This functionality is known to be incomplete, so discourage its use in
general-purpose kernels.

The only reason to use this driver is to support PCI hotplug on CNB20LE-
based machines that don't have ACPI, and there are very few such
systems.

30e664afb5 x86/PCI: don't use native Broadcom CNB20LE driver when ACPI is available
The broadcom_bus.c quirk was written (without benefit of documentation)
to support PCI hotplug on an old system that doesn't have ACPI.  As
such, we should only use it when the system doesn't have ACPI.

If the system does have ACPI and we need the host bridge description, we
should get it from the ACPI _CRS method.  On machines older than 2008,
we currently ignore _CRS, but that doesn't mean we should use
broadcom_bus.c.  It means we should either (a) do what we've done in the
past and assume everything in the PCI gap is routed to bus 0 (so hotplug
may not work), or (b) arrange to use _CRS.  This patch does (a).

415e12b237 PCI/ACPI: Request _OSC control once for each root bridge (v3)
Move the evaluation of acpi_pci_osc_control_set() (to request control of
PCI Express native features) into acpi_pci_root_add() to avoid calling
it many times for the same root complex with the same arguments.
Additionally, check if all of the requisite _OSC support bits are set
before calling acpi_pci_osc_control_set() for a given root complex.

6e8af08dfa PCI: enable pci=bfsort by default on future Dell systems
This patch enables pci=bfsort by default on future Dell systems.
It reads SMBIOS type 0xB1 vendor specific record and sets pci=bfsort
accordingly.

Offset  Name    Length  Value   Description

04      Flags0  Word    Varies  Bits 9-10
                                - 10:9 = 00  Unknown
                                - 10:9 = 01  Breadth First
                                - 10:9 = 10  Depth First
                                - 10:9 = 11  Reserved

1. Any time pci=bfsort has to be enabled on a system, we need to add the
   model number of the system to the white list. With this patch, that
   is not required.

2. Typically, model number has to be added to the white list when the
   system is under development. With this change, that is not required.

7f5db6a802 gpio: timbgpio: Fix up irq_data conversion breakage.
Commit a1f5f22adc ("gpio: timbgpio:

timbgpio_irq() over to take an irq_data * argument instead of an
unsigned int irq argument, as it is a flow handler, which still take
IRQ numbers for now.  (And on top of that, it was using the wrong
accessors.)

This fixes it up, and seems to build without warnings.

359ab9f5b1 power_supply: Add MAX17042 Fuel Gauge Driver
The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.

This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.

32385c7cf6 kernel: fix hlist_bl again
__d_rehash is dereferencing an almost-NULL pointer on my ARM926.
CONFIG_SMP=n and CONFIG_DEBUG_SPINLOCK=y.

The faulting instruction is:    strne   r3, [r2, #4]
and as can be seen from the register dump below, r2 is 0x00000001, hence
the faulting 0x00000005 address.

__d_rehash is essentially:

       spin_lock_bucket(b);
       entry->d_flags &= ~DCACHE_UNHASHED;
       hlist_bl_add_head_rcu(&entry->d_hash, &b->head);
       spin_unlock_bucket(b);

which is:

       bit_spin_lock(0, (unsigned long *)&b->head.first);
       entry->d_flags &= ~DCACHE_UNHASHED;
       hlist_bl_add_head_rcu(&entry->d_hash, &b->head);
       __bit_spin_unlock(0, (unsigned long *)&b->head.first);

bit_spin_lock(0, ptr) sets bit 0 of *ptr, in this case b->head.first if
CONFIG_SMP or CONFIG_DEBUG_SPINLOCK is set:

#if defined(CONFIG_SMP) || defined(CONFIG_DEBUG_SPINLOCK)
       while (unlikely(test_and_set_bit_lock(bitnum, addr))) {
               while (test_bit(bitnum, addr)) {
                       preempt_enable();
                       cpu_relax();
                       preempt_disable();
               }
       }
#endif

So, b->head.first starts off NULL, and becomes a non-NULL (address 1).
hlist_bl_add_head_rcu() does this:

static inline void hlist_bl_add_head_rcu(struct hlist_bl_node *n,
                                       struct hlist_bl_head *h)
{
       first = hlist_bl_first(h);
       n->next = first;
       if (first)
               first->pprev = &n->next;

It is the store to first->pprev which is faulting.

hlist_bl_first():

static inline struct hlist_bl_node *hlist_bl_first(struct hlist_bl_head *h)
{
       return (struct hlist_bl_node *)
               ((unsigned long)h->first & ~LIST_BL_LOCKMASK);
}

but:
#if defined(CONFIG_SMP)
#define LIST_BL_LOCKMASK        1UL
#else
#define LIST_BL_LOCKMASK        0UL
#endif

So, we have one piece of code which sets bit 0 of addresses, and another
bit of code which doesn't clear it before dereferencing the pointer if
!CONFIG_SMP && CONFIG_DEBUG_SPINLOCK.  With the patch below, I can again
sucessfully boot the kernel on my Versatile PB/926 platform.

337ce5d1c5 mfd: Support LP3974 RTC
The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.

If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.

This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.

de8255ccd2 i2c: Convert SCx200 driver from using raw PCI to platform device
The SCx200 ACB driver supports ISA hardware as well as PCI.  The PCI
hardware is CS5535/CS5536 based, and the device that it grabs is handled by
the cs5535-mfd driver. This converts the SCx200 driver to use a
platform_driver rather than the previous PCI hackery.

The driver used to manually track the iface list (via linked list); now it
only does this for ISA devices.  PCI ifaces are handled through standard
driver model lists.

It's unclear what happens in case of errors in the old ISA code; rather than
pretending the code actually cares, I've dropped the (implicit) ignorance
of return values and marked it with a comment.

419cdc54ea x86: OLPC: convert olpc-xo1 driver from pci device to platform device
The cs5535-mfd driver now takes care of the PCI BAR handling; this
means the olpc-xo1 driver shouldn't be touching the PCI device at all.

This patch uses both cs5535-acpi and cs5535-pms platform devices rather
than a single platform device because the cs5535-mfd driver may be used
by other CS5535 platform-specific drivers; OLPC doesn't get to dictate
that ACPI and PMS will always be used together.

in order to avoid multiple definitions. As the AB8500 is normally a
