Sven Wegener e74783ec3c i2c-dev: Return correct error code on class_create() failure
We need to convert the error pointer from class_create(), else we'll return the
successful return code from register_chrdev() on failure.

Uwe Kleine-Koenig 4ebb52d34f i2c-powermac: Fix section for probe and remove functions
__devexit for i2c_powermac_probe is obviously wrong.  In the definition
of struct platform_driver i2c_powermac_driver the remove function
i2c_powermac_remove is wrapped in __devexit_p, so it should be defined
using __devexit.

The OLPC doesn't support APM but also doesn't have DMI, so we can't detect
and disable it based on DMI data.  So, just disable based on machine_is_olpc()

Marc Dionne 1eda81495a x86: prevent stale state of c1e_mask across CPU offline/online, fix
Fix build error introduced by commit 4faac97d44 ("x86: prevent stale
state of c1e_mask across CPU offline/online").

process_32.c needs to include idle.h to get the prototype for
c1e_remove_cpu()

Jack Tan 5291925a9a [MIPS] Fixe the definition of PTRS_PER_PGD
When we use > 4KB's page size the original definition is not consistent
with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is
(14-2) + 14 = 26, PGDIR_SIZE is 2^26,so the PTRS_PER_PGD should be:

	2^32/2^26 = 2^6

but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).

So, this definition needs to be consistent with the PGDIR_SIZE.

And the new definition is consistent with the PGD init in pagetable_init().

Bruno Randolf 44ce17192a [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.

Alan Stern 5257d97a21 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.

While making some other changes to ti_usb_3410_5052, I noticed that the
changes made to move the firmware loading to a separate function are
broken (in ti_download_firmware(), status is set to -ENOMEM and never
changed).  This means the driver will never initialize the device
properly.  It looks like status was supposed to get the result of
ti_do_download().

David Brownell 01c1714265 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.

Geoff Levand 83a7982073 USB: fix hcd interrupt disabling
Commit de85422b94, '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.

David Brownell 0bcfeb3ec9 USB: ehci: fix some ehci hangs and crashes
I noticed that the "Refactor "if (handshake()) state = HC_STATE_HALT"
patch from earlier this year perpetuated a potential problem:  it can
mark the controller as halted when it's still running (but not acting
as, perhaps wrongly, expected).

That caused some hangs and crashes, rather than more polite failure
modes of a truly halted controller.  This patch forces a true halt,
and emits a (previously missing) diagnostic.

James Bottomley 44ea91c597 [SCSI] Fix hang with split requests
Sometimes, particularly for USB devices with the last sector bug,
requests get completed in chunks.  There's a bug in this in that if
one of the chunks gets an error, we complete that chunk with an error
but never move on to the remaining ones, leading to the request
hanging (because it's not fully completed).

Fix this by completing all remaining chunks if an error is encountered.

Anti Sullin f05596dbc9 atmel_serial: update the powersave handler to match serial core
This problem seems to be unnoticed so far:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=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.

Daisuke Nishimura a10cebf56c 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.

Michael Kerrisk 2d4c826677 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.

Jonathan Steel f9092f358b 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
page being a page that will shortly be copied to.

This patch ensures that kimage_alloc_page returns a page that was created
with the correct gfp flags.

I have verified the change and fixed the whitespace damage of the original
patch.  Jonathan did a great job of tracking this down after he hit the
problem.  -- Eric
