3b7ec117bf ipmi: support I/O resources in OF driver
The current OF probing assumes that the resource is IORESOURCE_MEM.  This
checks for the IORESOURCE_IO flag and behaves appropriately.  An I/O resource
can exist with an ipmi device node on a legacy ISA bus.

90898709df atmel_lcdfb: fix initialization of a pre-allocated framebuffer
Fix initialization of framebuffer not calling ioremap_writecombine() function
and not using internal SRAM for at91sam9rl.

This is a little rework of the "Don't initialize a pre-allocated framebuffer"
patch that corrects the call to ioremap_writecombine() function.

It also cuts the use of internal SRAM for at91sam9rl : it is a bit small
for a framebuffer.

3ef0f720e4 mm: fix infinite loop in filemap_fault
filemap_fault will go into an infinite loop if ->readpage() fails
asynchronously.

AFAICS the bug was introduced by this commit, which removed the wait after the
final readpage:

   commit d00806b183
   Author: Nick Piggin <npiggin@suse.de>
   Date:   Thu Jul 19 01:46:57 2007 -0700

       mm: fix fault vs invalidate race for linear mappings

Fix by reintroducing the wait_on_page_locked() after ->readpage() to make sure
the page is up-to-date before jumping back to the beginning of the function.

I've noticed this while testing nfs exporting on fuse.  The patch
fixes it.

3b73a22366 pnp: add ISAPnP MPU option quirks
The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but
work fine without one.  This adds (priority functional) IRQ-less options
for each port option to help systems with few available IRQs.

The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ.  Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front, not
back.

Doesn't use pnp_register_port_resource() for symetry with above.

This does not delete the AD1815 independent option even though it should
be empty after the IRQ transfer due to AD1816 coming with an empty but
still present independent option by default.

Was tested on AD1815, AD1816 and AZT2320.  The ALSA snd-ad1818a driver
also support the AZT2002 ID for MPU401 but this doesn't as I was unable to
test it.

bc033c9b5f pnp: add pnp_build_option() to the API
The subsequent AD181x quirk patch would like this as part of the API.
pnp_register_dependent_option() adds to the same dependent chain the quirk is
walking which is fairly unclean.  This enables a private option chain build

82f55af06a fix "lxfb: extend PLL table to support dotclocks below 25 MHz"
The following patch caused a regression with OLPC panels:

 commit 3888d4639e
    lxfb: extend PLL table to support dotclocks below 25 MHz

    Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
    make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
    MHz.  These are needed for small LCDs (e.g.  320x240).  Also inserts some
    intermediate steps between pre-existing frequencies.

The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched.  This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.

887b3ece65 9p: fix error path during early mount
There was some cleanup issues during early mount which would trigger
a kernel bug for certain types of failure.  This patch reorganizes the
cleanup to get rid of the bad behavior.

This also merges the 9pnet and 9pnet_fd modules for the purpose of
configuration and initialization.  Keeping the fd transport separate
from the core 9pnet code seemed like a good idea at the time, but in
practice has caused more harm and confusion than good.

Some files in the net/9p directory uses "int" for flags. This can

b32a09db4f add match_strlcpy() us it to make v9fs make uname and remotename parsing more robust
match_strcpy() is a somewhat creepy function: the caller needs to make sure
that the destination buffer is big enough, and when he screws up or
forgets, match_strcpy() happily overruns the buffer.

There's exactly one customer: v9fs_parse_options().  I believe it currently
can't overflow its buffer, but that's not exactly obvious.

The source string is a substing of the mount options.  The kernel silently
truncates those to PAGE_SIZE bytes, including the terminating zero.  See
compat_sys_mount() and do_mount().

The destination buffer is obtained from __getname(), which allocates from
name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX.

We're safe as long as PATH_MAX <= PAGE_SIZE.  PATH_MAX is 4096.  As far as
I know, the smallest PAGE_SIZE is also 4096.

Here's a patch that makes the code a bit more obviously correct.  It
doesn't depend on PATH_MAX <= PAGE_SIZE.

d6894b5be1 ath5k: Fix loop variable initializations
In ath5k_tasklet_rx, both status structures 'rxs' and 'rs' are
initialized at the top of the tasklet, but not within the loop.
If the loop is executed multiple times in the tasklet then the
variables may see changes from previous packets.

For TKIP, this results in 'Invalid Michael MIC' errors if two packets
are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by
mac80211 when it decrypts the first encrypted packet.  The subsequent
packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211
will not try to decrypt it.

We currently initialize all but two fields in the structures, so fix
the other two.

b0a6717994 mac80211: Set IEEE80211_TXPD_REQ_TX_STATUS for all TX frames
All interfaces should set the IEEE80211_TXPD_REQ_TX_STATUS flag for all TX frames
which will force the master interface to set the IEEE80211_TX_CTL_REQ_TX_STATUS
flag. This in turn will allow drivers to check for that flag before reporting
the TX status to mac80211.

This is very usefull when frames (like beacons, RTS and CTS-to-self) should not
be reported back to mac80211. Later we could add more extensive checks to
exclude more frames from being reported, or let mac80211 decide if it wants
the frame for status reporting or not.

v2: Monitor interfaces should also set IEEE80211_TXPD_REQ_TX_STATUS

  IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
  IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
  IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW

for noise we currently only have dBm:

  IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW

if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.

i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

fac371d9f0 mac80211: fix queue constant confusion
In commit 31ccc476b77234f6afb3 (mac80211: QoS related cleanups) I
accidentally changed these to use IEEE80211_MAX_AMPDU_QUEUES twice
which obviously is wrong, it should be IEEE80211_MAX_QUEUES once.
Currently harmless as they're both the same value anyway.

84e6dc9acf zd1211rw: initial IBSS support
this adds initial IBSS support for the zydas zd1211rw:
convince driver that it can do IBSS mode. add mac80211 beacon_update callback.

IBSS merge and TSF updates don't work yet, but it makes the driver usable in
ad-hoc networks.

736bc924fe atmel: use netstats in net_device structure
Use net_device_stats from net_device structure instead of local.
Kill atmel_get_stats function, because by default it is used
identical internal_stats function from net/core/dev.c
No need to memset stats to 0, because they are allocated by kzalloc.

P.S. Someone should cleanup init_atmel_card function from unneeded
initializations to 0/NULL. Out of scope for this patch.

15dbf1b7b7 iwl3945: do not delay hardware scan if it is a direct scan
iwl3945 <---> mac80211 <----> wpa_supplicant <---> NetworkManager

When a hardware scan is completed and another scan is requested in less
than two seconds, iwlwifi will not do the second scan and will pass the
error code -EAGAIN back to mac80211 where it quickly dies. The error
code is not passed along to the calling program wpa_supplicant. After a
timeout, wpa_supplicant will just give up but it will not know why the
scan failed. This is a weakness in the design.

I ran into this issue when I was trying to figure out why it takes more
an a minute for NetworkManager to connect after Networking has been
disabled and then re-enabled. I found a good deal of unnecessary work
being done because mac80211 requests authentication when the interface
is not configured, the ANY mode. I created an experimental passive
(NOTANY) mode for mac80211 to eliminate this case. Then NetworkManager
became so fast that I ran into the iwlwifi 2 second delay next scan
issue which we are discussing.

The patch resolves the problem by bypassing the delay if the scan request
is a direct scan. It should do less harm to the hardware.
