4defe4559e MIPS: Add uImage build target
Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot
image of vmlinux.bin.gz), and then symlinks it to uImage. This allows
for the use of other compression algorithms in future, and is how a few
other architectures do it.

It's enabled conditionally on load-y >= 0xffffffff80000000 which
hopefully allows 64bit kernels to also work as long as the load and
entry address can be represented by the 32bit addresses in the U-Boot
image format.

3185557d1a MIPS: Refactor load/entry address calculations
The vmlinux load address and entry address is calculated in multiple
places:
 - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or
   defined by the platform) and passes it to
   arch/mips/boot/compressed/Makefile.
 - arch/mips/boot/compressed/Makefile calculates kernel entry using nm.
 - arch/mips/lasat/image/Makefile calculates both load and entry address
   using nm.

Lets combine these in the main Makefile and then pass them as Make
parameters to each of the three boot image Makefiles (in boot/,
boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use
them, but will soon need to for U-Boot image targets.

The existing load-y definition is used in preference to calculating the
load address using nm.

38d2d649be MIPS: Refactor boot and boot/compressed rules
Split out the arch/mips/boot/ and arch/mips/boot/compressed/ targets
into boot-y and bootz-y variables. This makes it slightly cleaner to add
new targets.

3b29aa5ba2 MIPS: add <dt-bindings/> symlink
Add symlink to include/dt-bindings from arch/mips/boot/dts/include/ to
match the ones in ARM and Meta architectures so that preprocessed device
tree files can include various useful constant definitions.

See commit c58299a (kbuild: create an "include chroot" for DT bindings)
merged in v3.10-rc1 for details.

MIPS structures it's dts files a little differently to other
architectures, having a separate dts directory for each SoC/platform,
but most of the definitions in the dt-bindings/ directory are common so
for now lets just have a single "include chroot" for all MIPS platforms.

aca58a6620 gpio MIPS/OCTEON: Add a driver for OCTEON's on-chip GPIO pins.
The SOCs in the OCTEON family have 16 (or in some cases 20) on-chip
GPIO pins, this driver handles them all.  Configuring the pins as
interrupt sources is handled elsewhere (OCTEON's irq handling code).

7848ea7902 kbuild: Add MIPS specific files to generated package.
A lot of 64-bit systems supported by Linux/MIPS have boot firmware or
bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32
target exists to support these systems.  Therefore, it'd be nice if the tar-pkg
target recognised this, and included the right version when packaging up a
binary of the kernel.

This updates buildtar to support MIPS targets.  MIPS may use 'vmlinux'
or 'vmlinux.32' depending on the target system.  This uses 'vmlinux.32'
in preference to 'vmlinux' where present (although I should check which
is newer), including either file as /boot/vmlinux-${version}.

d8b74276f5 MIPS: cavium-octeon: fix I/O space setup on non-PCI systems
Fix I/O space setup, so that on non-PCI systems using inb()/outb()
won't crash the system. Some drivers may try to probe I/O space and for
that purpose we can just allocate some normal memory initially. Drivers
trying to reserve a region will fail early as we set the size to 0. If
a real I/O space is present, the PCI/PCIe support code will re-adjust
the values accordingly.

Tested with EdgeRouter Lite by enabling CONFIG_SERIO_I8042 that caused
the originally reported crash.

dynamic_dname() is both too much and too little for those - the

3955dfa821 staging: comedi: bug-fix NULL pointer dereference on failed attach
Commit dcd7b8bd63 ("staging: comedi: put
module _after_ detach" by myself) reversed a couple of calls in
`comedi_device_attach()` when recovering from an error returned by the
low-level driver's 'attach' handler.  Unfortunately, that introduced a
NULL pointer dereference bug as `dev->driver` is NULL after the call to
`comedi_device_detach()`.   We still have a pointer to the low-level
comedi driver structure in the `driv` variable, so use that instead.

4bf93b50fd nilfs2: fix issue with counting number of bio requests for BIO_EOPNOTSUPP error detection
Fix the issue with improper counting number of flying bio requests for
BIO_EOPNOTSUPP error detection case.

The sb_nbio must be incremented exactly the same number of times as
complete() function was called (or will be called) because
nilfs_segbuf_wait() will call wail_for_completion() for the number of
times set to sb_nbio:

  do {
      wait_for_completion(&segbuf->sb_bio_event);
  } while (--segbuf->sb_nbio > 0);

Two functions complete() and wait_for_completion() must be called the
same number of times for the same sb_bio_event.  Otherwise,
wait_for_completion() will hang or leak.

93dbc1b3b5 drivers/platform/olpc/olpc-ec.c: initialise earlier
Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

4a5a8aa6c9 ipv4: expose IPV4_DEVCONF
IP sends device configuration (see inet_fill_link_af) as an array
in the netlink information, but the indices in that array are not
exposed to userspace through any current santized header file.

It was available back in 2.6.32 (in /usr/include/linux/sysctl.h)
but was broken by:
  commit 02291680ff
  Author: Eric W. Biederman <ebiederm@xmission.com>
  Date:   Sun Feb 14 03:25:51 2010 +0000

    net ipv4: Decouple ipv4 interface parameters from binary sysctl numbers

Eric was solving the sysctl problem but then the indices were re-exposed
by a later addition of devconf support for IPV4

  commit 9f0f7272ac
  Author: Thomas Graf <tgraf@infradead.org>
  Date:   Tue Nov 16 04:32:48 2010 +0000

    ipv4: AF_INET link address family

Putting them in /usr/include/linux/ip.h seemed the logical match
for the DEVCONF_ definitions for IPV6 in /usr/include/linux/ip6.h
