p9_conn_destroy() first kills all current requests by calling
p9_conn_cancel(), then waits for the request list to be cleared by
waiting on p9_conn->equeue. After that, polling is stopped and the
trans is destroyed. This sequence has a few problems.
* Read and write works were never cancelled and the p9_conn can be
destroyed while the works are running as r/w works remove requests
from the list and dereference the p9_conn from them.
* The list emptiness wait using p9_conn->equeue wouldn't trigger
because p9_conn_cancel() always clears all the lists and the only
way the wait can be triggered is to have another task to issue a
request between the slim window between p9_conn_cancel() and the
wait, which isn't safe under the current implementation with or
without the wait.
This patch fixes the problem by first stopping poll, which can
schedule r/w works, first and cancle r/w works which guarantees that
r/w works are not and will not run from that point and then calling
p9_conn_cancel() and do the rest of destruction.

9p trans modules aren't refcounted nor were they unregistered
properly. Fix it.
* Add 9p_trans_module->owner and reference the module on each trans
instance creation and put it on destruction.
* Protect v9fs_trans_list with a spinlock. This isn't strictly
necessary as the list is manipulated only during module loading /
unloading but it's a good idea to make the API safe.
* Unregister trans modules when the corresponding module is being
unloaded.
* While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().

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.

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.

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 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.

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,

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.

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.
