44901a9684 libata: Avoid overflow in ata_tf_read_block() when tf->hba_lbal > 127
Phillip O'Donnell <phillip.odonnell@gmail.com> pointed out that the same
sign extension bug that was fixed in commit ba14a9c2 ("libata: Avoid
overflow in ata_tf_to_lba48() when tf->hba_lbal > 127") also appears to
exist in ata_tf_read_block().  Fix this by adding a cast to u64.

8a8bc22332 libata: revert convert-to-block-tagging patches
This patch reverts the following three commits which convert libata to
use block layer tagging.

 43a49cbdf3
 e013e13bf6
 2fca5ccf97

Although using block layer tagging is the right direction, due to the
tight coupling among tag number, data structure allocation and
hardware command slot allocation, libata doesn't work correctly with
the current conversion.

The biggest problem is guaranteeing that tag 0 is always used for
non-NCQ commands.  Due to the way blk-tag is implemented and how SCSI
starts and finishes requests, such guarantee can't be made.  I'm not
sure whether this would actually break any low level driver but it
doesn't look like a good idea to break such assumption given the
frailty of ATA controllers.

So, for the time being, keep using the old dumb in-libata qc
allocation.

43e61711d4 Don't ask twice about not including staging drivers
The "Exclude staging drivers" question is there so that we don't build
staging drivers for allyesconfig or allnoconfig settings, but it's very
irritating when you've already said "no" to staging drivers earlier.

There is absolutely no point in declining twice - once you've declined
the staging drivers, you're done.

So make the second question depend on the first question having been
answered in the affirmative.

It seems that some cards are slightly out of spec and occasionally
will not be able to complete a write in the alloted 250 ms [1].
Incease the timeout slightly to allow even these cards to function

0c4b95455f Staging: only build the tree if we really want to
This Kconfig change allows the common 'make allmodconfig' and
'make allyesconfig' build options to skip the staging tree, which is
probably what you want to have happen anyway.

This makes the linux-next developer's life a lot easier so he doesn't
have to worry about changes that break the staging tree, that's for me
to worry about...

06a7f05876 atmel_serial: keep clock off when it's not needed
The atmel_serial driver is mismanaging its clock by leaving it on at all
times ...  the whole point of clock management is to leave it off unless
it's actively needed, which conserves power!!

Although the kernel doesn't actually hang without my fix, it does
discard quite a lot of early console output.

The result still looks correct:

          usart        users= 1 on   35000000 Hz, for atmel_usart.0
          usart        users= 0 off  35000000 Hz, for atmel_usart.2

when using ttyS0 as serial console.

a684e7d330 fbdev: fix fb_compat_ioctl() deadlocks
commit 3e680aae4e ("fb: convert
lock/unlock_kernel() into local fb mutex") introduced several deadlocks
in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion,
unlike lock_kernel().  This broke frame buffer applications on 64-bit
systems with a 32-bit userland.

commit 120a37470c ("framebuffer compat_ioctl
deadlock") fixed one of the deadlocks.

This patch fixes the remaining deadlocks:
  - Revert commit 120a37470c,
  - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(),
  - Change all callsites of fb_ioctl() where info->lock is already held to
    call do_fb_ioctl() instead,
  - Add sparse annotations to all routines that take info->lock.

Do not send scan command if no channels to scan.

This avoids a Microcode error as reported in:

2420ebc104 iwl3945: clear scanning bits upon failure
This patch ensures we clear any scan status bit when
an error occurs while sending the scan command. It is
the implementation of patch:
"iwlwifi: clear scanning bits upon failure"
for iwl3945.

c793033945 ath5k: correct handling of rx status fields
ath5k_rx_status fields rs_antenna and rs_more are u8s, but we
were setting them with bitwise ANDs of 32-bit values.

As a consequence, jumbo frames would not be discarded as intended.
Then, because the hw rate value of such frames is zero, and, since
"ath5k: rates cleanup", we do not fall back to the basic rate, such
packets would trigger the following WARN_ON:

964d277743 iwlagn: avoid sleep in softirq context
__ieee80211_tasklet_handler -> __ieee80211_rx ->
	__ieee80211_rx_handle_packet -> ieee80211_invoke_rx_handlers ->
	ieee80211_rx_h_decrypt -> ieee80211_crypto_tkip_decrypt ->
	ieee80211_tkip_decrypt_data -> iwl4965_mac_update_tkip_key ->
	iwl_scan_cancel_timeout -> msleep

Ooops!

Avoid the sleep by changing iwl_scan_cancel_timeout with
iwl_scan_cancel and simply returning on failure if the scan persists.
This will cause hardware decryption to fail and we'll handle a few more
frames with software decryption.

502c12e1ef iwlwifi: clear scanning bits upon failure
In iwl_bg_request_scan function, if we could not send a
scan command it will go to done.
In done it does the right thing to call mac80211 with
scan complete, but the problem is STATUS_SCAN_HW is still
set causing any future scan to fail. Fix by clearing the scanning status
bits if scan fails.

934f6c3f8e Revert "ath5k: honor FIF_BCN_PRBRESP_PROMISC in STA mode"
Unfortunately, the result was that mac80211 didn't see all the beacons
it actually wanted to see.  This caused lost associations.

Hopefully we can revisit this when mac80211 is less greedy about seeing
beacons directly...

This reverts commit 063279062a.

f1cd14ae52 md: linear: Fix a division by zero bug for very small arrays.
We currently oops with a divide error on starting a linear software
raid array consisting of at least two very small (< 500K) devices.

The bug is caused by the calculation of the hash table size which
tries to compute sector_div(sz, base) with "base" being zero due to
the small size of the component devices of the array.

Fix this by requiring the hash spacing to be at least one which
implies that also "base" is non-zero.

This bug has existed since about 2.6.14.
