[MIPS] au1000: Fix gpio direction
When setting the direction of one GPIO pin we have to keep the state of the
other pins, hence use binary OR. Also gpio_direction_output() wants to set an
initial value, so add that too.
This fixes a problem with the USB power switch on mtx-1 boards.

USB: revert recovery from transient errors
This patch (as1135) essentially reverts the major parts of two earlier
patches to usbcore, because they ended up causing a regression.
Trying to recover from transient communication errors can lead to
other problems, because operations that failed during the error period
are not always retried. The simplest example is the initial
Set-Config request sent after device enumeration; if it gets lost then
it will not be retried and the device will remain unconfigured.
This patch restores the old behavior in which any port disconnect or
port disable causes the entire device structure to be removed, fixing a
reported regression.

USB: fix EHCI periodic transfers
As noted by Stefan Neis <Stefan.Neis@kobil.com>, we had a recent
regression with EHCI periodic transfers, in some (seemingly not
all that common) cases.
The root cause was that the schedule activation was only loosely
coupled to the addition or removal of transfers, so two different
execution contexts could both think they had to deactivate (or
conversely activate) the schedule. So this fix tightens that
coupling, managing it more like a refcount.

USB: fix hcd interrupt disabling
Commit
de85422b94ddb23c021126815ea49414047c13dc, 'USB: fix interrupt
disabling for HCDs with shared interrupt handlers' changed usb_add_hcd()
to strip IRQF_DISABLED from irqflags prior to calling request_irq()
with the justification that such a removal was necessary for shared
interrupts to work properly. Unfortunately, the change in that commit
unconditionally removes the IRQF_DISABLED flag, causing problems on
platforms that don't use a shared interrupt but require IRQF_DISABLED.
This change adds a check for IRQF_SHARED prior to removing the
IRQF_DISABLED flag.
Fixes the PS3 system startup hang reported with recent Fedora and
OpenSUSE kernels.
Note that this problem is hidden when CONFIG_LOCKDEP=y (ps3_defconfig),
as local_irq_enable_in_hardirq() is defined as a null statement for
that config.

b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2
has changed the serial core behavior to not to suspend the port if the
device is enabled as a wakeup source. If the AT91 system goes to slow
clock mode, the port should be suspended always and the clocks should be
switched off. The patch attached updates the atmel_serial driver to match
the changes in serial core.
Also, the interrupts are disabled when the clock is disabled. If we
disable the clock with interrupts enabled, an interrupt may get stuck. If
this is the DBGU interrupt, this blocks the OR logic at system controller
and thus all other sysc interrupts.

memcg: check under limit at shrink_usage
Current memory cgroup(both in mainline and -mm) doesn't account swap
caches as memory(swap cache support is dropped temporarily now).
So try_to_free_mem_cgroup_pages doesn't reflect the count of pages that
have been moved to swap cache.
But this makes mem_cgroup_shrink_usage fail easily if most of the pages
are anon/shmem, and then shmem_getpage returns -ENOMEM and the process
will be killed.
This patch adds res_counter_check_under_limit to avoid these cases.
BTW, even if swap cache support is enabled again, if a process is moved to
another cgroup, which has been just made, between precharge and
shrink_usage in shmem_getpage, shrink_usage may fail just because there is
no pages to reclaim.
So this change would make sense anyway.

sys_paccept: disable paccept() until API design is resolved
The reasons for disabling paccept() are as follows:
* The API is more complex than needed. There is AFAICS no demonstrated
use case that the sigset argument of this syscall serves that couldn't
equally be served by the use of pselect/ppoll/epoll_pwait + traditional
accept(). Roland seems to concur with this opinion
(http://thread.gmane.org/gmane.linux.kernel/723953/focus=732255). I
have (more than once) asked Ulrich to explain otherwise
(http://thread.gmane.org/gmane.linux.kernel/723952/focus=731018), but he
does not respond, so one is left to assume that he doesn't know of such
a case.
* The use of a sigset argument is not consistent with other I/O APIs
that can block on a single file descriptor (e.g., read(), recv(),
connect()).
* The behavior of paccept() when interrupted by a signal is IMO strange:
the kernel restarts the system call if SA_RESTART was set for the
handler. I think that it should not do this -- that it should behave
consistently with paccept()/ppoll()/epoll_pwait(), which never restart,
regardless of SA_RESTART. The reasoning here is that the very purpose
of paccept() is to wait for a connection or a signal, and that
restarting in the latter case is probably never useful. (Note: Roland
disagrees on this point, believing that rather paccept() should be
consistent with accept() in its behavior wrt EINTR
(http://thread.gmane.org/gmane.linux.kernel/723953/focus=732255).)
I believe that instead, a simpler API, consistent with Ulrich's other
recent additions, is preferable:
accept4(int fd, struct sockaddr *sa, socklen_t *salen, ind flags);
(This simpler API was originally proposed by Ulrich:
http://thread.gmane.org/gmane.linux.network/92072)
If this simpler API is added, then if we later decide that the sigset
argument really is required, then a suitable bit in 'flags' could be added
to indicate the presence of the sigset argument.
At this point, I am hoping we either will get a counter-argument from
Ulrich about why we really do need paccept()'s sigset argument, or that he
will resubmit the original accept4() patch.

kexec: fix segmentation fault in kimage_add_entry
A segmentation fault can occur in kimage_add_entry in kexec.c when loading
a kernel image into memory. The fault occurs because a page is requested
by calling kimage_alloc_page with gfp_mask GFP_KERNEL and the function may
actually return a page with gfp_mask GFP_HIGHUSER. The high mem page is
returned because it was swapped with the kernel page due to the kernel

This patch ensures that kimage_alloc_page returns a page that was created

tick_do_timer_cpu keeps track of the CPU which updates jiffies
via do_timer. The value -1 is used to signal, that currently no
CPU is doing this. There are two cases, where the variable can
have this state:
boot:
necessary for systems where the boot cpu id can be != 0
nohz long idle sleep:
When the CPU which did the jiffies update last goes into
a long idle sleep it drops the update jiffies duty so
another CPU which is not idle can pick it up and keep
jiffies going.
Using the same value for both situations is wrong, as the CPU online
code can see the -1 state when the timer of the newly onlined CPU is
setup. The setup for a newly onlined CPU goes through periodic mode
and can pick up the do_timer duty without being aware of the nohz /
highres mode of the already running system.
Use two separate states and make them constants to avoid magic

pcmcia: Fix broken abuse of dev->driver_data
PCMCIA abuses dev->private_data in the probe methods. Unfortunately it
continues to abuse it after calling drv->probe() which leads to crashes and
other nasties (such as bogus probes of multifunction devices) giving errors like
pcmcia: registering new device pcmcia0.1
kernel: 0.1: GetNextTuple: No more items
Extract the passed data before calling the driver probe function that way
we don't blow up when the driver reuses dev->private_data as its right.
As its close to the final release just move the hack so it works out,
hopefully someone will be sufficiently embarrassed to produce a nice rework
for 2.6.28.

netdev: simple_tx_hash shouldn't hash inside fragments
Currently simple_tx_hash is hashing inside of udp fragments. As a result
packets are getting getting sent to all queues when they shouldn't be.
This causes a serious performance regression which can be seen by sending
UDP frames larger than mtu on multiqueue devices. This change will make
it so that fragments are hashed only as IP datagrams w/o any protocol
information.

sparc64: Fix disappearing PCI devices on e3500.
Based upon a bug report by Meelis Roos.
The OF device layer builds properties by matching bus types and
applying 'range' properties as appropriate, up to the root.
The match for "PCI" busses is looking at the 'device_type' property,
and this does work %99 of the time.
But on an E3500 system with a PCI QFE card, the DEC 21153 bridge
sitting above the QFE network interface devices has a 'name' of "pci",
but it completely lacks a 'device_type' property. So we don't match
it as a PCI bus, and subsequently we end up with no resource values at
all for the devices sitting under that DEC bridge.
