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.

75d2f18088 [ARM] 3345/1: Fix interday RTC alarms
Patch from Uli Luckas

This is a bugfix.

The comment in arch/arm/common/rtctime.c explains it:
* FIXME: for now, we just copy the alarm time because we're lazy (and
* is therefore buggy - setting a 10am alarm at 8pm will not result in
* the alarm triggering.)

This patch adds one day to the alarm iff the alarm wrapped beyond midnight and therefore appears to be in the past.

c27a2164a3 [ARM] 3340/1: Fix the PCI setup for direct master access to SDRAM
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
image is needed for Versatile/PB since the original windows were 1MB and
not able to cover the whole SDRAM (now extended to 256MB). The patch also
fixes the PCI IRQ mapping for slot #2.

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.

cf535ea52e [PATCH] m32r: update sys_tas() routine
This patch updates and fixes sys_tas() routine for m32r.

In the previous implementation, a lockup rarely caused at sys_tas()
routine in SMP environment.

> > paged in.  If we convert it to use get_user() then that's an improvement,
> > but we must not run get_user() under spinlock or local_irq_disable().

I rewrote sys_tas() routine by using "lock -> unlock" instructions, and
utilizing the m32r's interrupt handling characteristics; the m32r processor
can accept interrupts only at the 32-bit instruction boundary.  So, the
"unlock" instruction can be executed continuously after the "lock"
instruction execution without any interruptions.

In addition, to solve such a page_fault problem, I use a fixup code like
get_user().

And, as for the kernel lockup problem, we found that a calling
do_page_fault() routine with disabling interrupts might cause a lockup at
flush_tlb_others(), because we checked a completion of IPI handler's
operations in a spin-locked critical section.

Therefore, by using "lock -> unlock" code, we can implement the sys_tas()
rouitine without disabling interrupts explicitly, then no lockups would
happen at flush_tlb_others(), I hope.

Compile check and some working test in SMP environment have done.

Another bug was when V=V was enabled we checked if hardware has SIGA-sync

lost initiative on FCP devices and input queue stalled.  Running devices in
