Throughput was severely affected in Intel Pinetrail platforms
because of a DMA problem in C3 state. This patch fixes this
issue.

The HW opmode is blindly set to monitor type on monitor mode
change notification. This overrides the opmode when one of the
interfaces is still running as non-monitor iftype. So the monitoring
information needs to be maintained seperately.

This bug seems to be due to commit 27ae60f8f7aac ("ipw2x00: replace
"ieee80211" with "libipw" where appropriate"), where Pavel did this:
- libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net);
+ libipw_proc = proc_mkdir("ieee80211", init_net.proc_net);
but then the cleanup was kept as
remove_proc_entry(DRV_NAME, init_net.proc_net);
in both places (both in the failure case and in the unload case). The
error string is also total crap, and says
"Unable to create " DRV_NAME " proc directory\n");
Even though it doesn't actually create a proc directory named DRV_NAME at all.
So that patch looks like total and utter crap to me. The commit message says
"Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface."
but the thing is, it really didn't fix anything but that one create
thing. It needs to fix all the other cases too.

As noted by Steve Chen, since commit
f5fff5dc8a7a3f395b0525c02ba92c95d42b7390 ("tcp: advertise MSS
requested by user") we can end up with a situation where
tcp_select_initial_window() does a divide by a zero (or
even negative) mss value.
The problem is that sometimes we effectively subtract
TCPOLEN_TSTAMP_ALIGNED and/or TCPOLEN_MD5SIG_ALIGNED from the mss.
Fix this by increasing the minimum from 8 to 64.

Robin Holt tried to boot a 16TB machine and found some limits were
reached : sysctl_tcp_mem[2], sysctl_udp_mem[2]
We can switch infrastructure to use long "instead" of "int", now
atomic_long_t primitives are available for free.

packet_getname_spkt() doesn't initialize all members of sa_data field of
sockaddr struct if strlen(dev->name) < 13. This structure is then copied
to userland. It leads to leaking of contents of kernel stack memory.
We have to fully fill sa_data with strncpy() instead of strlcpy().
The same with packet_getname(): it doesn't initialize sll_pkttype field of
sockaddr_ll. Set it to zero.

There is a possibility malicious users can get limited information about
uninitialized stack mem array. Even if sk_run_filter() result is bound
to packet length (0 .. 65535), we could imagine this can be used by
hostile user.
Initializing mem[] array, like Dan Rosenberg suggested in his patch is
expensive since most filters dont even use this array.
Its hard to make the filter validation in sk_chk_filter(), because of
the jumps. This might be done later.
In this patch, I use a bitmap (a single long var) so that only filters
using mem[] loads/stores pay the price of added security checks.
For other filters, additional cost is a single instruction.
[ Since we access fentry->k a lot now, cache it in a local variable
and mark filter entry pointer as const. -DaveM ]

Followup of commit ef885afbf8a37689 (net: use rcu_barrier() in
rollback_registered_many)
dst_dev_event() scans a garbage dst list that might be feeded by various
network notifiers at device dismantle time.
Its important to call dst_dev_event() after other notifiers, or we might
enter the infamous msleep(250) in netdev_wait_allrefs(), and wait one
second before calling again call_netdevice_notifiers(NETDEV_UNREGISTER,
dev) to properly remove last device references.
Use priority -10 to let dst_dev_notifier be called after other network
notifiers (they have the default 0 priority)

some 8168 do not like it. The change needs to be tightened with
a specific 8168 version.

SCSI commands may be issued between __scsi_add_device() and dev->sdev
assignment, so it's unsafe for ata_qc_complete() to dereference
dev->sdev->locked without checking whether it's NULL or not. Fix it.

On 2.6.37-rc1, omap platform internals for SCM have changed,
so the build is broken again.
drivers/staging/tidspbridge/core/tiomap3430.c:26:
fatal error: plat/control.h: No such file or directory
This is a totally ugly layer violation, but needed until
omap_ctrl_set_dsp_boot*() are provided.

Also, don't be picky about the location, which incidentally fixes the
build since MEMBLOCK_REAL_LIMIT is gone on 2.6.37.

There was commented out transfer_flags initialization.
And i think memset should fill entire structure, not only length of
pointer to it.
This makes the driver work properly now on my hardware.

Remove unnecessary cast of firmware base address to integer before
adding an offset.
Fix direct use of sk_buff::network_header which is an offset rather
than a pointer on 64-bit architectures.

Whenever the mac address of an batman interface is changed
check_known_mac_addr() is called to print a warning if the newly added
mac address exists an another batman interface. While looping through
the batman interface list check_known_mac_addr() only compares mac
addresses and does not make sure they belong to different interfaces,
thus always printing a warning.
