The default chip-delay of 25us is a bit too tight for some DNS-320's,
and D-Link seem to specify 30us in their kernels for both devices.
Increase to 35us to make sure the NAND is stable.

Now that the EHCI driver has DT support, drop old style configuration
of it and add DT in its place. Since all the boards enable the EHCI,
enable it by default in kirkwood.dtsi. Any new boards which don't have
USB can specifically disable it.

It has been a while since dove_defconfig was updated to recent development.
This patch adds all currently available Dove boards, including a DT-enabled
machine.
DT support requires to allow ATAGS passed by boot loader as most of them are
not yet capable of passing DT blobs. Also OF_SERIAL is enabled to actually
see the bootlog.
Finally, sdhci driver for Dove, mv_cesa, GPIO LEDs, and highmem support is
added.

This commit converts the 'LaCie Ethernet Disk mini v2' board to the
Device Tree. All devices that have existing Device Tree bindings are
converted over to the Device Tree, the other devices remain
instantiated in the old way, until the respective drivers get the
needed Device Tree bindings.

This commit adds basic DT support for the Orion5x SoC family. It adds
an orion5x.dtsi description of the Orion5x SoC as well as the needed
DT_MACHINE structure to support boards converted to DT in the future.
So far, the Device Tree contains the interrupt controller, the GPIO
bank, the UART controllers, the SPI controller, the watchdog, the SATA
controller, the I2C controller and the cryptographic engine.

can be read with dd and produce exactly the same data before and
after conversion. So, the partition offsets at least should be fine.

Ok, I did convert the i2c definition to use the devicetree.
The adt7476 device itself is not at reach of device tree,
AFAIK and requires more work at there?
Thanks for your valuable comments. Following is a new patch that
should address the problems and mistakes you pointed and also
some of the pointed by Jason Cooper. The nand and i2c are now
defined at DT and I also removed the pointless defines and
ARM_APPENDED_DTB. It is based against the Linus' official
3.6 version.

This patch adds DT board setup for the LaCie NAS Network Space Mini v2
(aka SafeBox). The hardware characteristics are very close to those of
the Network Space Lite v2. The main difference are:
- A GPIO fan which is only available on the NS2 Mini.
- A single USB host port is wired on the NS2 Mini. The NS2 Lite provides
an additional dual-mode USB port (host/device).

This patch adds DT board setup for the LaCie NAS Network Space Lite v2.
This board is derived from the Network Space v2 and a lot of hardware
characteristics are shared.
- CPU: Marvell 88F6192 800Mhz
- SDRAM memory: 128MB DDR2 200Mhz
- 1 SATA port: internal
- Gigabit ethernet: PHY Marvell 88E1318
- Flash memory: SPI NOR 512KB (Macronix MX25L4005A)
- i2c EEPROM: 512 bytes (24C04 type)
- 2 USB2 ports: host and host/device
- 1 push button
- 1 SATA LED (bi-color, blue and red)
Note that the SATA LED is not compatible with the driver leds-ns2. The
LED behaviour ("on", "off" or "SATA activity blink") is controlled via
a single MPP (21).

Revert commit 7f1290f2f2a4 ("mm: fix-up zone present pages")
That patch tried to fix a issue when calculating zone->present_pages,
but it caused a regression on 32bit systems with HIGHMEM. With that
change, reset_zone_present_pages() resets all zone->present_pages to
zero, and fixup_zone_present_pages() is called to recalculate
zone->present_pages when the boot allocator frees core memory pages into
buddy allocator. Because highmem pages are not freed by bootmem
allocator, all highmem zones' present_pages becomes zero.
Various options for improving the situation are being discussed but for
now, let's return to the 3.6 code.

The OMAP patches contain some fixes for MUSB/PHY on omap4 which ends

The CBUS UART's interrupt number was wrong conflicting with the interrupt
being tied to the Intel PIIX4. Since the PIIX4's interrupt is registered
before the CBUS UART which is not being used on most systems this would
not be noticed.
Attempts to open the ttyS2 CBUS UART would result in:
genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade)

Select HAVE_ALIGNED_STRUCT_PAGE on s390, so that the slub allocator can make
use of compare and swap double for lockless updates. This increases the size
of struct page to 64 bytes (instead of 56 bytes), however the performance gain
justifies the increased size:
- now excactly four struct pages fit into a single cache line; the
case that accessing a struct page causes two cache line loads
does not exist anymore.
- calculating the offset of a struct page within the memmap array
is only a simple shift instead of a more expensive multiplication.

access_ok() returns always "true" on s390. Therefore all access_ok()
invocations are rather pointless.
However when walking page tables we need to make sure that everything
is within bounds of the ASCE limit of the task's address space.
So remove the access_ok() call and add the same check we have in
get_user_pages_fast().

Otherwise we might calculate e.g. a pud pointer which is not
within a pud and dereference it.
So check against TASK_SIZE (which is the ASCE limit) before
walking page tables.

QEMU first retrieves the supported features via KVM_GET_SUPPORTED_CPUID
and then sets them later. So guest's X86_FEATURE_XSAVE should be masked
out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with
X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with
X86_FEATURE_XSAVE even on hosts that do not support it, might be
susceptible to this attack from inside the guest as well.
Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support.

Since commit edc88ceb0 (ARM: be really quiet when building with 'make -s') the
following output is generated when building a kernel for ARM:
echo ' Kernel: arch/arm/boot/Image is ready'
Kernel: arch/arm/boot/Image is ready
Building modules, stage 2.
echo ' Kernel: arch/arm/boot/zImage is ready'
Kernel: arch/arm/boot/zImage is ready
As per Documentation/kbuild/makefiles.txt the correct way of using kecho is
'@$(kecho)'.
Make this change so no more unwanted 'echo' messages are displayed.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren <tony@atomide.com>:
This series fixes an annoying regression to make MUSB working
on omap4 again. Although it's getting rather late for these
changes for the -rc cycle, it is important as many devices
are using MUSB for charging and connectivity.
With the USB PHY changes, MUSB started using the newly added
drivers/usb/phy/omap-usb2.c driver introduced by commit
657b306a (usb: phy: add a new driver for omap usb2 phy)
that is using the newly introduced drivers/bus/omap-ocp2scp.c
introduced by commit 26a84b3e (drivers: bus: add a new driver
for omap-ocp2scp).
These changes allowed dropping a lot of PHY related code from
arch/arm/mach-omap2/omap_phy_internal.c and have it live in
the device driver like it should with commit c9e4412a (arm: omap:
phy: remove unused functions from omap-phy-internal.c).
However, MUSB on omap4 broke with these changes for legacy
platform data boot, and now only works with device tree for
omap4. Unfortunately we are still few critical bindings away
from being able to make omap4 usbale with device tree.
Fix the regression properly by adding platform data support
to the ocp2scp driver so we can avoid adding back the driver
code to arch/arm/mach-omap2.

The current topology code confuses core id vs physical package id.
In other words /sys/devices/system/cpu/cpuX/topology/core_id
displays the physical_package_id (aka socket id) instead of the
core id.
The physical_package_id sysfs attribute always displays "-1"
instead of the socket id.
Fix this mix-up with a small patch which defines and initializes
topology_physical_package_id correctly and fixes the broken
core id handling.

If user space is running in primary mode it can switch to secondary
or access register mode, this is used e.g. in the clock_gettime code
of the vdso. If a signal is delivered to the user space process while
it has been running in access register mode the signal handler is
executed in access register mode as well which will result in a crash
most of the time.
Set the address space control bits in the PSW to the default for the
execution of the signal handler and make sure that the previous
address space control is restored on signal return. Take care
that user space can not switch to the kernel address space by
modifying the registers in the signal frame.

Pull sparc fixes from David Miller:
"Several build/bug fixes for sparc, including:
1) Configuring a mix of static vs. modular sparc64 crypto modules
didn't work, remove an ill-conceived attempt to only have to build
the device match table for these drivers once to fix the problem.
Reported by Meelis Roos.
2) Make the montgomery multiple/square and mpmul instructions actually
usable in 32-bit tasks. Essentially this involves providing 32-bit
userspace with a way to use a 64-bit stack when it needs to.
3) Our sparc64 atomic backoffs don't yield cpu strands properly on
Niagara chips. Use pause instruction when available to achieve
this, otherwise use a benign instruction we know blocks the strand
for some time.
4) Wire up kcmp
5) Fix the build of various drivers by removing the unnecessary
blocking of OF_GPIO when SPARC.
6) Fix unintended regression wherein of_address_to_resource stopped
being provided. Fix from Andreas Larsson.
7) Fix NULL dereference in leon_handle_ext_irq(), also from Andreas
Larsson."

We tried linking in a single built object to hold the device table,
but only works if all of the sparc64 crypto modules get built the same
way (modular vs. non-modular).
Just include the device ID stub into each driver source file so that
the table gets compiled into the correct result in all cases.
