acpi_pad: fix power_saving thread deadlock
The acpi_pad driver can get stuck in destroy_power_saving_task()
waiting for kthread_stop() to stop a power_saving thread. The problem
is that the isolated_cpus_lock mutex is owned when
destroy_power_saving_task() calls kthread_stop(), which waits for a
power_saving thread to end, and the power_saving thread tries to
acquire the isolated_cpus_lock when it calls round_robin_cpu(). This

printk: flush continuation lines immediately to console
Continuation lines are buffered internally, intended to merge the
chunked printk()s into a single record, and to isolate potentially
racy continuation users from usual terminated line users.
This though, has the effect that partial lines are not printed to
the console in the moment they are emitted. In case the kernel
crashes in the meantime, the potentially interesting printed
information would never reach the consoles.
Here we share the continuation buffer with the console copy logic,
and partial lines are always immediately flushed to the available
consoles. They are still buffered internally to improve the
readability and integrity of the messages and minimize the amount
of needed record headers to store.

f948501b36c6 ("Make hard_irq_disable() actually hard-disable

->irq_happened will never be zero right after a hard_irq_disable
so the compiler removes the call to cede_processor completely.
The bug was introduced back in the lazy interrupt handling rework

nothing.

powerpc/ftrace: Do not trace restore_interrupts()
As I was adding code that affects all archs, I started testing function
tracer against PPC64 and found that it currently locks up with 3.4
kernel. I figured it was due to tracing a function that shouldn't be, so
I went through the following process to bisect to find the culprit:
cat /debug/tracing/available_filter_functions > t
num=`wc -l t`
sed -ne "1,${num}p" t > t1
let num=num+1
sed -ne "${num},$p" t > t2
cat t1 > /debug/tracing/set_ftrace_filter
echo function /debug/tracing/current_tracer
<failed? bisect t1, if not bisect t2>
It finally came down to this function: restore_interrupts()
I'm not sure why this locks up the system. It just seems to prevent
scheduling from occurring. Interrupts seem to still work, as I can ping
the box. But all user processes freeze.
When restore_interrupts() is not traced, function tracing works fine.

ppc64: fix missing to check all bits of _TIF_USER_WORK_MASK in preempt
In entry_64.S version of ret_from_except_lite, you'll notice that
in the !preempt case, after we've checked MSR_PR we test for any
TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work
or not. However, in the preempt case, we do a convoluted trick to
test SIGPENDING only if PR was set and always test NEED_RESCHED ...
but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So
that means that with preempt, we completely fail to test for things
like single step, syscall tracing, etc...
This should be fixed as the following path:
- Test PR. If not set, go to resume_kernel, else continue.
- If go resume_kernel, to do that original do_work.
- If else, then always test for _TIF_USER_WORK_MASK to decide to do
that original user_work, else restore directly.

- https://lkml.org/lkml/2011/11/14/74
But this did fix did not work on all systems
as Suspend/resume regression was reported on Lenovo S10-3
recently by Dave.
- https://lkml.org/lkml/2012/5/27/115
It looked like with commit
e978aa7d broke suspend and
with commit
3439a8da resume was not working with acpi_idle driver.
This patch fixes the regression that caused this issue
in the first place. acpi_idle_suspend flag is essential on
some x86 systems to prevent the cpus from going to deeper C-states
when suspend is triggered ( commit
b04e7bdb984 )
So reverting the commit
3439a8da is essential.
By default, irqs are disabled in cpu_idle arch specific call
and re-enabled in idle state return path . During suspend,
the acpi_idle_suspend flag is set, which
prevents the cpus from going to deeper idle states,
it is essential to enabling the irqs in this return path too.
To address the suspend issue,
we were not re-enabling the interrupts while returning from
acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set.
and this caused suspend failure.
In addition to the above, to improve the readability of the code,
return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend
return path. Implying that the system is currently busy when suspend
is in progress, which prevents the cpus from entering deeper C-states.

FCoE target mode was experiencing issues due to the fact that we were

already stripped the frame down to 52 or 56 depending on the use of VLANs.
This was resulting in the FCoE DDP logic having issues since it thought the

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.

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
b56a39ac263e5b8cafedd551a49c2105e68b98c2 ("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
4a77a5a06ec66ed05199b301e7c25f42f979afdc ("printk: use mutex
lock to stop syslog_seq from going wild"), so I'd recommend reverting

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.

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.

printk: fix regression in SYSLOG_ACTION_CLEAR
Commit
7ff9554bb578ba02166071d2d487b7fc7d860d62 (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".

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.

bug.h: Fix up CONFIG_BUG=n implicit function declarations.
Commit
2603efa31a03 ("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.
