This is an update to the "usb-ehci-update-toggle-state-for-linked-qhs"
patch. Since an HCD's endpoint_reset method can be called in
interrupt context, it mustn't assume that interrupts are enabled or
that it can sleep.
So we revert to the original way of refreshing QHs' toggle bits. Now
the endpoint_reset method merely clears the toggle flag in the device
structure (as was done before) and starts an async QH unlink. When the
QH is linked again, after the unlink finishes and an URB is queued,
the qh_refresh() routine will update the QH's toggle bit.

- Even the positive checks are buggy: a positive intersection
check has four natural cases while we checked only for three,
missing the (addr < start && addr2 == end) case for example.
- The variables are mis-named, making it non-obvious how the
check was done.
- It needlessly uses u64 instead of unsigned long. Since these
are kernel memory pointers and we explicitly exclude highmem
ranges anyway we cannot ever overflow 32 bits, even if we
could. (and on 64-bit it doesnt matter anyway)
All in one, this function needs a total revamp. I used Linus's
suggestions minus the paranoid checks (we cannot overflow really
because if we get totally bad DMA ranges passed far more things
break in the systems than just DMA debugging). I also fixed a
few other small details i noticed.

block: fix sg SG_DXFER_TO_FROM_DEV regression
I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use
the block layer mapping API (2.6.28).
Douglas Gilbert explained SG_DXFER_TO_FROM_DEV:
http://www.spinics.net/lists/linux-scsi/msg37135.html
=
The semantics of SG_DXFER_TO_FROM_DEV were:
- copy user space buffer to kernel (LLD) buffer
- do SCSI command which is assumed to be of the DATA_IN
(data from device) variety. This would overwrite
some or all of the kernel buffer
- copy kernel (LLD) buffer back to the user space.
The idea was to detect short reads by filling the original
user space buffer with some marker bytes ("0xec" it would
seem in this report). The "resid" value is a better way
of detecting short reads but that was only added this century
and requires co-operation from the LLD.
=
This patch changes the block layer mapping API to support this
semantics. This simply adds another field to struct rq_map_data and
enables __bio_copy_iov() to copy data from user space even with READ
requests.
It's better to add the flags field and kills null_mapped and the new
from_user fields in struct rq_map_data but that approach makes it
difficult to send this patch to stable trees because st and osst
drivers use struct rq_map_data (they were converted to use the block
layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer
mapping API.

Commit
c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how
cxgb3 looks up the netdev_queue it stashes away in a qset during
initialization. For multiport devices, the TX queue index it uses is
offset by the first_qset index of each port. This leads to a crash
once LLTX is removed, since hard_start_xmit is called with one TX
queue lock held, while the TX reclaim timer task grabs a different
(wrong) TX queue lock when it frees skbs.

net: adding memory barrier to the poll and receive callbacks
Adding memory barrier after the poll_wait function, paired with
receive callbacks. Adding fuctions sock_poll_wait and sk_has_sleeper
to wrap the memory barrier.
Without the memory barrier, following race can happen.
The race fires, when following code paths meet, and the tp->rcv_nxt
and __add_wait_queue updates stay in CPU caches.
CPU1 CPU2
sys_select receive packet
... ...
__add_wait_queue update tp->rcv_nxt
... ...
tp->rcv_nxt check sock_def_readable
... {
schedule ...
if (sk->sk_sleep && waitqueue_active(sk->sk_sleep))
wake_up_interruptible(sk->sk_sleep)
...
}
If there was no cache the code would work ok, since the wait_queue and
rcv_nxt are opposit to each other.
Meaning that once tp->rcv_nxt is updated by CPU2, the CPU1 either already
passed the tp->rcv_nxt check and sleeps, or will get the new value for
tp->rcv_nxt and will return with new data mask.
In both cases the process (CPU1) is being added to the wait queue, so the
waitqueue_active (CPU2) call cannot miss and will wake up CPU1.
The bad case is when the __add_wait_queue changes done by CPU1 stay in its
cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1 will then
endup calling schedule and sleep forever if there are no more data on the
socket.

But unfortunately the LVDS device is still initialized on the boxes based on
mobile chipset in KMS mode. It brings that this pipe occupied by LVDS can't be
used for other output device.
After checking the acpidump we find that there is no LID device on such boxes.
In such case we can use the LID device to decide whether the LVDS device should
be initialized.
If there is no LID device, we can think that there is no LVDS device. It is
unnecessary to initialize the LVDS output device.
If there exists the LID device, it will continue the current flowchart.
Maybe on some boxes there is no LVDS device but the LID device is found. In

[WATCHDOG] SA1100 watchdog maximum timeout
This patch replaces the hardcoded 255 seconds limit for a real limit based on
oscr_freq.
Also, the 'firmware_version' field is changed to '1' to allow the user
space application to easily detect that this driver supports a higher
maximum timeout.

In the beep tone calculation for IDT/STAC codecs, lower numbers correspond

tinny laptop speakers, resulting in complaints).

UBIFS: fix corruption dump
In the 'ubifs_recover_leb()' function, when we find corrupted
empty space, we dump 8K starting from the offset where the last
node ends. This is OK if the corrupted empty space is somewhere
near that offset. But if the corruption is far at the end of the
LEB, we will dump all 0xFF bytes and complitely ignore the
interesting data. This is observed on a PPC ("kilauea") with
NOR flash.
This patch changes the behavior and teaches UBIFS to print only
interesting data. I.e., now we find where corruption starts and
start dumping from that offset.

UBIFS: small amendments in the LEB scanning code
This patch fixes few minor things I've spotted while going through
code:
1. Better document return codes
2. If 'ubifs_scan_a_node()' returns some thing we do not expect,
treat this as an error.
3. Try to do recovery only when 'ubifs_scan()' returns %-EUCLEAN,
not on any error.
4. If empty space starts at a non-aligned address, print a message.

UBIFS: dump a little more in case of corruptions
In case of corruptions, dump 8192 bytes instead of 4096. The
largest node is 4096+ bytes, so it is better to see a node
boundary, which is not always possible when only 4096 bytes
are printed.

netpoll: Fix carrier detection for drivers that are using phylib
Using early netconsole and gianfar driver this error pops up:
netconsole: timeout waiting for carrier
It appears that net/core/netpoll.c:netpoll_setup() is using
cond_resched() in a loop waiting for a carrier.
The thing is that cond_resched() is a no-op when system_state !=
SYSTEM_RUNNING, and so drivers/net/phy/phy.c's state_queue is never
scheduled, therefore link detection doesn't work.
I belive that the main problem is in cond_resched()[1], but despite
how the cond_resched() story ends, it might be a good idea to call
msleep(1) instead of cond_resched(), as suggested by Andrew Morton.

Atheros Kconfig needs to be dependent on WLAN_80211
Atheros top level menu needs a "depends WLAN_80211" to properly indent

This is purely a visual issue but it effects all subsequent drivers.
The issue is the top level menu does not include a dependency on
WLAN_80211 so within the tree structure, Atheros is at the same level as
WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with
all subsequent drives, so it is really a subordinate.
