0781191cf6 skge: genesis phy initialzation
The SysKonnect Genesis based board would fail on initialization

a9cdab869e skge: NAPI/irq race fix
Fix a race in the receive NAPI, irq handling. The interrupt clear and the
start need to be separated.  Otherwise there is a window between the last

5d06a99f54 r8169: fix broken ring index handling in suspend/resume
rtl8169_hw_start() requires that the descriptor ring indexes be
set to zero. Let a deferred invocation of rtl8169_reset_task()
handle it. Enabling a few power management bits will not hurt
either.

suspend/resume is issued with irq on: the spinlock do not need
to save the irq flag.

a80614d1ad sbp2: update 36byte inquiry workaround (fix compatibility regression)
Since about Linux 2.6.14, sbp2's inquiry workaround did not work anymore
due to changes in the SCSI layer. Update it to become effective again.
Testing one of the two known affected bridges has shown that skip_ms_page_8
is required as well.

Also, make force_inquiry_hack tunable via /sys/module/sbp2/parameters.

35bdddb83f sbp2: variable status FIFO address (fix login timeout)
Let the ieee1394 core select a suitable 1394 address range for sbp2's
status FIFO instead of using a fixed range. Since the core only selects
addresses which are guaranteed to be out of the "physical range" as per
OHCI 1.1, this patch also fixes an old bug:

OHCI controllers which implement a writeable PhysicalUpperBound register
included sbp2's status FIFO in the physical range. That way sbp2 was
never notified of a succesful login and always failed after timeout.
Affected OHCI host adapters include ALi and Fujitsu controllers.

As another side effect of this patch, the status FIFO is no longer
located in a range for which OHCI chips perform "posted writes". Each
status write now requires a response subaction. But since large data
transfers involve only few status writes, there is no measurable
decrease of I/O throughput. What's more, the status FIFO is now safe
from potential host bus errors. Nevertheless, posted writes could be
re-enabled by extensions to the ARM features of the 1394 stack.

bf637ec3ef sbp2: fix another deadlock after disconnection
If there were commands enqueued but not completed before an SBP-2 unit

df666b9c51 [ARM] 3325/2: GPIO function to control multi-drive (open collector) capability
Patch from Andrew Victor

This patch adds the at91_set_multi_drive() function to enable/disable
the multi-drive (open collector) pin capability on the AT91RM9200
processor.

This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200
board as it will not allow the board reset line to be pulled low if the
pullup is not driven as an open collector output as the boards are wired
to the USB connector on both the DK/EK.

This version of the patch updates it to 2.6.16-rc4.

Patch from Catalin Marinas

The initial code did not configure the inbound memory windows for direct
master access to the SDRAM. This patch creates a 1:1 mapping between the
Versatile/PB PCI memory windows and its SDRAM. Note that an updated FPGA

not able to cover the whole SDRAM (now extended to 256MB). The patch also

fa675765af Revert mount/umount uevent removal
This change reverts the 033b96fd30 commit
from Kay Sievers that removed the mount/umount uevents from the kernel.
Some older versions of HAL still depend on these events to detect when a
new device has been mounted.  These events are not correctly emitted,
and are broken by design, and so, should not be relied upon by any
future program.  Instead, the /proc/mounts file should be polled to
properly detect this kind of event.

A feature-removal-schedule.txt entry has been added, noting when this
interface will be removed from the kernel.

b00dc3ad74 [PATCH] tmpfs: fix mount mpol nodelist parsing
I've been dissatisfied with the mpol_nodelist mount option which was
added to tmpfs earlier in -rc.  Replace it by mpol=policy:nodelist.

And it was broken: a nodelist is a comma-separated list of numbers and
ranges; the mount options are a comma-separated list of token=values.
Whoops, blindly strsep'ing on commas doesn't work so well: since we've
no numeric tokens, and unlikely to add them, use that to distinguish.

Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject
all its options as invalid if not NUMA.  /proc shows MPOL_PREFERRED
as "prefer", so use that name for the policy instead of "preferred".

Enforce that mpol=default has no nodelist; that mpol=prefer has one
node only; that mpol=bind has a nodelist; but let mpol=interleave use
node_online_map if no nodelist given.  Describe this in tmpfs.txt.
