The new Kconfig option to build "staging" drivers (code in
drivers/staging/) is seen in all except three architectures (arm, h8300,
cris), because in these cases arch/$ARCH/Kconfig does NOT source
drivers/Kconfig.
This patch adds the source "drivers/staging/Kconfig" to
arch/$ARCH/Kconfig for these three exceptional cases.

People keep on doing

Quite a few 64-bit architectures are using `long' for their
s64/u64 types. We should convert them all to `long long'.
Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.
This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.

The sparc allmodconfig build broke due to enabling of the
branch_tracer that does some very clever things with
all if conditions. This caused my gcc 3.4.5 to be so confused that
it emitted a warning:
arch/sparc/mm/fault_32.c: In function `do_sparc_fault':
arch/sparc/mm/fault_32.c:176: warning: 'fixup' might be used uninitialized in this function
And with -Werror this broke the build.
Refactor code so it:
1) becomes more readable
2) no longer emit a warning with the branch_tracer enabled

branch_tracer that does some very clever things with
all if conditions. This caused my gcc 3.4.5 to be so confused that

arch/sparc/mm/init_64.c:272: warning: 'page' might be used uninitialized in this function
And with -Werror this broke the build.
Refactor code so it:
1) becomes more readable
2) no longer emit a warning with the branch_tracer enabled
The refactoring uses a small helper function (flush_dcache()).

On 32-bit system with CONFIG_LBD getblk can fail because provided
block number is too big. Add error checks so we fail gracefully if
getblk() returns NULL (which can also happen on memory allocation
failures).

This mount option is largely superfluous, and in fact the way it was
implemented was buggy; if a filesystem which did not have the extents
feature flag was mounted -o extents, the filesystem would attempt to
create and use extents-based file even though the extents feature flag
was not eabled. The simplest thing to do is to nuke the mount option
entirely. It's not all that useful to force the non-creation of new
extent-based files if the filesystem can support it.

The AF_CAN core delivered always cloned sk_buffs to the AF_CAN
protocols, although this was _only_ needed by the can-raw protocol.
With this (additionally documented) change, the AF_CAN core calls the
callback functions of the registered AF_CAN protocols with the original
(uncloned) sk_buff pointer and let's the can-raw protocol do the
skb_clone() itself which omits all unneeded skb_clone() calls for other
AF_CAN protocols.

This patch adds GRO interfaces for hardware-assisted VLAN reception.
With this in place we're now at parity with LRO as far as the
interface is concerned. That is, you can now take any LRO driver
and convert it over to GRO.
As the CB memory clashes with GRO's use of CB, I've removed it
entirely by storing dev in skb->dev. This is OK because VLAN
gets called first thing in netif_receive_skb and skb->dev is
not used in between us calling netif_rx and netif_receive_skb
getting called.

Previously GRO's only entry point from the outside is through
napi_gro_receive and napi_gro_frags. These interfaces are for
device drivers.
This patch rearranges things to provide a new set of interfaces
for VLANs. These interfaces are for internal use only. The
VLAN code itself can then provide a set of entry points for
device drivers.

These variables are only used with an interface that just dumps their
values into registers to be passed to the hypervisor. The arguments
to that interface are declared to be "unsigned long", so make these
variables match. The macros are only used with these variables, so make
them match as well.
This code is currently only built for 64bit powerpc, so the transformation
is really a noop. If the interface was ever ported to 32 bit, it would
almost certainly still use registers to pass the parameters and so
"unsigned long" would still be appropriate.

ehea_plpar_hcall9() takes an "unsigned long" array to return its results,
so change the arrays we pass to it to match. This is currently only
64 bit code, so the transformation is actually a noop, but because
ehea_plpar_hcall9() copies the values of registers into the array,
if this was ported to a 32 bit hypervisor interface "unsigned long"
would probably still be the correct type.

Devices sometimes have memory where all or parts of it can not be mapped to
userspace. But it might still be possible to access this memory from
userspace by other means. An example are PCI cards that advertise not only
mappable memory but also ioport ranges. On x86 architectures, these can be
accessed with ioperm, iopl, inb, outb, and friends. Mike Frysinger (CCed)
reported a similar problem on Blackfin arch where it doesn't seem to be easy
to mmap non-cached memory but it can still be accessed from userspace.
This patch allows kernel drivers to pass information about such ports to
userspace. Similar to the existing mem[] array, it adds a port[] array to
struct uio_info. Each port range is described by start, size, and porttype.
If a driver fills in at least one such port range, the UIO core will simply
pass this information to userspace by creating a new directory "portio"
underneath /sys/class/uio/uioN/. Similar to the "mem" directory, it will
contain a subdirectory (portX) for each port range given.
Note that UIO simply passes this information to userspace, it performs no
action whatsoever with this data. It's userspace's responsibility to obtain
access to these ports and to solve arch dependent issues. The "porttype"
attribute tells userspace what kind of port it is dealing with.
This mechanism could also be used to give userspace information about GPIOs
related to a device. You frequently find such hardware in embedded devices,
so I added a UIO_PORT_GPIO definition. I'm not really sure if this is a good
idea since there are other solutions to this problem, but it won't hurt much
anyway.

Use the newly introduced pci_ioremap_bar() function in drivers/uio.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.
