b265158399 MIPS: SMTC: Remove duplicate structure field initialization
The definition of the irq_ipi structure has two initializations of the
flags field.  This combines them.

[Ralf: The issue was originally introduced by commit
be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp.
033890b084 (kernel.org).  The original
intention of the code was to initialize .flags with both flags ored together.
The broken C code as actually implemented will be compiled by an equally
broken gcc to use only the last initialization, that is IRQF_PERCPU
which means this turned into an SMTC bug for 2.6.23 and newer.]

The semantic match that finds this problem is as follows:

342a597146 pty: reconnect the BSD TIOCSPTLCK handling to legacy ptys
David Howells noticed (due to the compiler warning about an unused
'pty_ops_bsd' variable) that we haven't actually been using the code
that implements TIOCSPTLCK for legacy pty handling.  It's been that way
since 2.6.26, commit 3e8e88ca05 to be
exact ("pty: prepare for tty->ops changes").

DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do.  But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.

And clean it up a bit while we're at it.

635b75fc18 percpu: make pcpu_setup_first_chunk() failures more verbose
The parameters to pcpu_setup_first_chunk() come from different sources
depending on architecture and can be quite complex.  The function runs
various sanity checks on the parameters and triggers BUG() if
something isn't right.  However, this is very early during the boot
and not reporting exactly what the problem is makes debugging even
harder.

Add PCPU_SETUP_BUG() macro which prints out enough information about
the parameters.  As the macro still puts separate BUG() for each
check, it won't lose any information even on the situations where only
the program counter can be retrieved.

While at it, also bump pcpu_dump_alloc_info() message to KERN_INFO so
that it's visible on the console if boot fails to complete.

6ea529a203 percpu: make embedding first chunk allocator check vmalloc space size
Embedding first chunk allocator maintains the distances between units
in the vmalloc area and thus needs vmalloc space to be larger than the
maximum distances between units; otherwise, it wouldn't be able to
create any dynamic chunks.  This patch makes the embedding first chunk
allocator check vmalloc space size and if the maximum distance between
units is larger than 75% of it, print warning and, if page mapping
allocator is available, fail initialization so that the system falls
back onto it.

This should work around percpu allocation failure problems on certain
sparc64 configurations where distances between NUMA nodes are larger
than the vmalloc area and makes percpu allocator more robust for
future configurations.

a70c691376 sparc64: implement page mapping percpu first chunk allocator
Implement page mapping percpu first chunk allocator as a fallback to
the embedding allocator.  The next patch will make the embedding
allocator check distances between units to determine whether it fits
within the vmalloc area so that this fallback can be used on such
cases.

sparc64 currently has relatively small vmalloc area which makes it
impossible to create any dynamic chunks on certain configurations
leading to percpu allocation failures.  This and the next patch should
allow those configurations to keep working until proper solution is
found.

While at it, mark pcpu_cpu_distance() with __init.

0c570cdeb8 PM / yenta: Fix cardbus suspend/resume regression
Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume.  In particular, PCI devices without drivers have been handled
this way since commit 355a72d75b
(PCI: Rework default handling of suspend and resume).  Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.

To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend.  Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

8f1546cadf wext: add back wireless/ dir in sysfs for cfg80211 interfaces
The move away from having drivers assign wireless handlers,
in favour of making cfg80211 assign them, broke the sysfs
registration (the wireless/ dir went missing) because the
handlers are now assigned only after registration, which is
too late.

Fix this by special-casing cfg80211-based devices, all
of which are required to have an ieee80211_ptr, in the
sysfs code, and also using get_wireless_stats() to have
the same values reported as in procfs.

b7a794048f iwlwifi: fix 3945 ucode info retrieval after failure
When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.

This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.

Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

2fac9717a0 iwlwifi: fix debugfs buffer handling
We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.

Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.

Issue was discovered and discussed during testing of
https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

4be3bd8ccc cfg80211: don't set privacy w/o key
When wpa_supplicant is used to connect to open networks,
it causes the wdev->wext.keys to point to key memory, but
that key memory is all empty. Only use privacy when there
is a default key to be used.

Currently, cfg80211's SIOCGIWAP implementation returns
the BSSID that the user set, even if the connection has
since been dropped due to other changes. It only should
return the current BSSID when actually connected.

Also do a small code cleanup.

47379052b5 net: Add explicit bound checks in net/socket.c
The sys_socketcall() function has a very clever system for the copy
size of its arguments. Unfortunately, gcc cannot deal with this in
terms of proving that the copy_from_user() is then always in bounds.
This is the last (well 9th of this series, but last in the kernel) such
case around.

With this patch, we can turn on code to make having the boundary provably
right for the whole kernel, and detect introduction of new security
accidents of this type early on.

There is a potential double-kfree in net/bridge/br_if.c.  If br_fdb_insert
fails, then the kobject is put back (which calls kfree due to the kobject
release), and then kfree is called again on the net_bridge_port.  This

f278a2f7bb tty: Fix regressions caused by commit b50989dc
The following commit made console open fails while booting:

	commit b50989dc44
	Author: Alan Cox <alan@linux.intel.com>
	Date:   Sat Sep 19 13:13:22 2009 -0700

	tty: make the kref destructor occur asynchronously

Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:

INIT open /dev/console Input/output error

It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229

The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.

Fix it as per the following Alan's suggestion:

  Fun but it's actually not a bug and the fix is wrong in itself as
  the port may be closing but not yet being destructed, in which case
  it seems to do the wrong thing.  Opening a tty that is closing (and
  could be closing for long periods) is supposed to return -EIO.

  I suspect a better way to deal with this and keep the old console
  timing is to split tty->shutdown into two functions.

  tty->shutdown() - called synchronously just before we dump the tty
  onto the waitqueue for destruction

  tty->cleanup() - called when the destructor runs.

  We would then do the shutdown part which can occur in IRQ context
  fine, before queueing the rest of the release (from tty->magic = 0
  ...  the end) to occur asynchronously

  The USB update in -next would then need a call like

       if (tty->cleanup)
               tty->cleanup(tty);

  at the top of the async function and the USB shutdown to be split
  between shutdown and cleanup as the USB resource cleanup and final
  tidy cannot occur synchronously as it needs to sleep.

  In other words the logic becomes

       final kref put
               make object unfindable

       async
               clean it up
