fe85227347 Revert "mmc: omap_hsmmc: Enable Auto CMD12"
This patch reverts the commit dba3c29ea4.

After bisecting, this commit dba3c29 is found to ruin micro-SD card data
(writing incorrect file, or fs is corrupt after several times mount)
on the beagle-xm revB, and reverting the commit will fix the problem.

Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about
the Auto CMD12 Enable bit.
        - SDIO does not support this feature.
        - SD card only.
Looks it is not suitable to always enable Auto CMD12 in host controller
driver.

Considered that the commit is not mature enough, so ask to revert it
first.

d380443cd0 mmc: block: fix the data timeout issue with ACMD22
If multi block write operation fails for SD card, during
error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22)
to know how many blocks were already programmed by card.

But mmc_sd_num_wr_blocks() function which sends the ACMD22
calculates the data timeout value from csd.tacc_ns and
csd.tacc_clks parameters which will be 0 for block addressed
(>2GB cards) SD card. This would result in timeout_ns and
timeout_clks being 0 in the mmc_request passed to host driver.
This means host controller would program its data timeout timer
value with 0 which could result in DATA TIMEOUT errors from
controller.

To fix this issue, mmc_sd_num_wr_blocks() should instead
just call the mmc_set_data_timeout() to calculate the
data timeout value. mmc_set_data_timeout() function
ensures that non zero timeout value is set even for
block addressed SD cards.

116e90b23f syslog: fill buffer with more than a single message for SYSLOG_ACTION_READ
The recent changes to the printk buffer management resulted in
SYSLOG_ACTION_READ to only return a single message, whereas previously
the buffer would get filled as much as possible. As, when too small to
fit everything, filling it to the last byte would be pretty ugly with
the new code, the patch arranges for as many messages as possible to
get returned in a single invocation. User space tools in at least all
SLES versions depend on the old behavior.

This at once addresses the issue attempted to get fixed with commit
b56a39ac26 ("printk: return -EINVAL if
the message len is bigger than the buf size"), and since that commit
widened the possibility for losing a message altogether, the patch
here assumes that this other commit would get reverted first
(otherwise the patch here won't apply).

Furthermore, this patch also addresses the problem dealt with in
commit 4a77a5a06e ("printk: use mutex
lock to stop syslog_seq from going wild"), so I'd recommend reverting
that one too (albeit there's no direct collision between the two).

6e1c39c6b0 ALSA: hda - Fix power-map regression for HP dv6 & co
The recent fix for power-map controls (commit b0791dda81) caused
regressions on some other HP laptops.  They have fixed pins but these
pins are exposed as jack-detectable.  Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.

This patch adds the check of connection and it assumes the no jack
detection is available for fixed pins no matter what pin capability
says.

9bd0c15fcf drm/nouveau/fbcon: using nv_two_heads is not a good idea
nv_two_heads() was never meant to be used outside of pre-nv50 code.  The
code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific
chipsets to 1 CRTC based on (pci_device & 0x0ff0).

The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which
gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing
memory corruption because there's actually 2 CRTCs..

This switches fbcon to use the CRTC count directly from the mode_config
structure, which will also fix the same issue on Kepler boards which have
4 CRTCs.

commit 8259573b (ARM: OMAP2+: nand: Make board_onenand_init() visible

removing the static in the header file, it created a duplicate definition

7975059db5 clk: Allow late cache allocation for clk->parents
Parent clocks for muxes are cached in clk->parents to
avoid frequent lookups, however the cache allocation happens
only during clock registeration and later clk_set_parent()
assumes a cache space available and allocated.

This is not entirely true for platforms which do early clock
registerations wherein the cache allocation using kzalloc
could fail during clock registeration.

Allow cache allocation to happen later as part of clk_set_parent()
to help such cases and avoid crashes assuming a cache being
available.

While here also replace existing kmalloc() with kzalloc()
in the file.

fa809e2fd6 ipv6: fib: fix fib dump restart
Commit 2bec5a369e (ipv6: fib: fix crash when changing large fib
while dumping it) introduced ability to restart the dump at tree root,
but failed to skip correctly a count of already dumped entries. Code
didn't match Patrick intent.

We must skip exactly the number of already dumped entries.

Note that like other /proc/net files or netlink producers, we could
still dump some duplicates entries.

b41772abeb rcu: Stop rcu_do_batch() from multiplexing the "count" variable
Commit b1420f1c (Make rcu_barrier() less disruptive) rearranged the
code in rcu_do_batch(), moving the ->qlen manipulation to follow
the requeueing of the callbacks.  Unfortunately, this rearrangement
clobbered the value of the "count" local variable before the value
of rdp->qlen was adjusted, resulting in the value of rdp->qlen being
inaccurate.  This commit therefore introduces an index variable "i",
avoiding the inadvertent multiplexing.

eac9ac6d1f iwlwifi: fix activating inactive stations
When authentication/association timed out, the driver would
complain bitterly, printing the message
ACTIVATE a non DRIVER active station id ... addr ...

The cause turns out to be that when the AP station is added
but we don't associate, the IWL_STA_UCODE_INPROGRESS is set
but never cleared. This then causes iwl_restore_stations()
to attempt to resend it because it uses the flag internally
and uploads even if it didn't set it itself.

To fix this issue and not upload the station again when it
has already been removed by mac80211, clear the flag after
adding it in case we add it only for association.

ff0b804632 wlcore: drop INET dependency
Mainline build reports:

warning: (WL12XX) selects WLCORE which has unmet direct dependencies (NETDEVICES && WLAN && WL_TI && GENERIC_HARDIRQS && MAC80211 && INET)

The INET dependency was added in commit
3c6af5b54f:
    wl1271_main.c:(.text+0x271052): undefined reference to `unregister_inetaddr_
notifier'
    wl1271_main.c:(.text+0x2714d7): undefined reference to `register_inetaddr_no
tifier'

    Driver is doing some filtering based on IP addresses...

but this driver no longer has that code and it builds fine even when
CONFIG_INET is not enabled, so drop that dependency and eliminate the
kconfig warning message.

bed3d9c0b7 ath9k: fix dynamic WEP related regression
commit 7a532fe713
ath9k_hw: fix interpretation of the rx KeyMiss flag

This commit used the rx key miss indication to detect packets that were
passed from the hardware without being decrypted, however it seems that
this bit is not only undefined in the static WEP case, but also for
dynamically allocated WEP keys. This caused a regression when using
WEP-LEAP.

This patch fixes the regression by keeping track of which key indexes
refer to CCMP keys and only using the key miss indication for those.

4661e3568a printk: fix regression in SYSLOG_ACTION_CLEAR
Commit 7ff9554bb5 (printk: convert
byte-buffer to variable-length record buffer) introduced a regression
by accidentally removing a "break" statement from inside the big
switch in printk's do_syslog().  The symptom of this bug is that the
"dmesg -C" command doesn't only clear the kernel's log buffer; it also
disables console logging.

This patch (as1561) fixes the regression by adding the missing
"break".

eb3979f64d stable: Allow merging of backports for serious user-visible performance issues
Distribution kernel maintainers routinely backport fixes for users that
were deemed important but not "something critical" as defined by the
rules. To users of these kernels they are very serious and failing to fix
them reduces the value of -stable.

The problem is that the patches fixing these issues are often subtle and
prone to regressions in other ways and need greater care and attention.
To combat this, these "serious" backports should have a higher barrier
to entry.

This patch relaxes the rules to allow a distribution maintainer to merge
to -stable a backported patch or small series that fixes a "serious"
user-visible performance issue. They should include additional information on
the user-visible bug affected and a link to the bugzilla entry if available.
The same rules about the patch being already in mainline still apply.

09682c1dd3 bug.h: Fix up CONFIG_BUG=n implicit function declarations.
Commit 2603efa31a ("bug.h: Fix up powerpc build regression") corrected
the powerpc build case and extended the __ASSEMBLY__ guards, but it also
got caught in pre-processor hell accidentally matching the else case of
CONFIG_BUG resulting in the BUG disabled case tripping up on
-Werror=implicit-function-declaration.

It's not possible to __ASSEMBLY__ guard the entire file as architecture
code needs to get at the BUGFLAG_WARNING definition in the GENERIC_BUG
case, but the rest of the CONFIG_BUG=y/n case needs to be guarded.

Rather than littering endless __ASSEMBLY__ checks in each of the if/else
cases we just move the BUGFLAG definitions up under their own
GENERIC_BUG test and then shove everything else under one big
__ASSEMBLY__ guard.

Build tested on all of x86 CONFIG_BUG=y, CONFIG_BUG=n, powerpc (due to
it's dependence on BUGFLAG definitions in assembly code), and sh (due to
not bringing in linux/kernel.h to satisfy the taint flag definitions used
by the generic bug code).

Hopefully that's the end of the corner cases and I can abstain from ever
having to touch this infernal header ever again.
