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().

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.

Commit de85422b, '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.

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.

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.

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.

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.

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

The wdt285.c watchdog driver is producing a number of
sparse errors due to missing __user attributes to calls
to put_user and copy_to_user, as well as in the prototype
of watchdog_write.

__asr_toggle() is always called with asr_lock held.
But there is unnecessary spin_unlock() call in __asr_toggle().

Just like in the arch/sparc64/kernel/of_device.c code fix commit
071d7f4c3b411beae08d27656e958070c43b78b4 ("sparc64: Fix SMP bootup
with CONFIG_STACK_DEBUG or ftrace.") we have to check the OF device
node name for "pci" instead of relying upon the 'device_type' property
being there on all PCI bridges.

Tested by Meelis Roos, and confirmed to make the PCI QFE devices
reappear on the E3500 system.
