2012-06-12ASoC: tegra+wm8903: turn of mic detect when card is removedStephen Warren
If mic detect is left enabled and the WM8903 detects a status change, the WM8903 driver will make a callback against the free()d jack, which will cause a crash. This problem can be triggered by fully initializing an audio card, then removing and re-inserting the machine driver module.

2012-06-12leds: don't disable blinking when writing the same value to delay_on or ↵Rafal Prylowski
delay_off Function led_set_software_blink() assumes that blink timer is still running, but commit 488bc35bf40df89d37486c1826b178a2fba36ce7 introduced disabling of blink timer before each call to led_set_software_blink().

The assembler entry code calls directly to the syscall_trace_enter() and syscall_trace_leave() functions. But currently they are conditionaly compiled out for the non-MMU classic m68k CPU types (so 68328 for example), resulting in a link error: LD vmlinux arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x1c): undefined reference to `syscall_trace_enter' arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x4c): undefined reference to `syscall_trace_leave' Change the conditional check that includes these functions to be true for the !defined(CONFIG_MMU) case as well.

2012-06-12m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU typesGreg Ungerer
When building for non-MMU based classic 68k CPU types (like the 68328 for example) you get a compilation error: CC arch/m68k/kernel/time.o arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’ include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here The arch_gettimeoffset() code is included when building for these CPU types, but it shouldn't be. Those machine types do not have CONFIG_ARCH_USES_GETTIMEOFFSET set. The fix is simply to conditionally include the arch_gettimeoffset() code on that same config setting that specifies its use or not.

2012-06-11lpc_eth: add missing ndo_change_mtu()Eric Dumazet
lpc_eth does a copy of transmitted skbs to DMA area, without checking skb lengths, so can trigger buffer overflows : memcpy(pldat->tx_buff_v + txidx * ENET_MAXF_SIZE, skb->data, len); One way to get bigger skbs is to allow MTU changes above the 1500 limit.

2012-06-11edac: Do alignment logic properly in edac_align_ptr()Chris Metcalf
The logic was checking the sizeof the structure being allocated to determine whether an alignment fixup was required. This isn't right; what we actually care about is the alignment of the actual pointer that's about to be returned. This became an issue recently because struct edac_mc_layer has a size that is not zero modulo eight, so we were taking the correctly-aligned pointer and forcing it to be misaligned. On Tile this caused an alignment exception. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-06-11edac: avoid mce decoding crash after edac driver unloadedChen Gong
Some edac drivers register themselves as mce decoders via notifier_chain. But in current notifier_chain implementation logic, it doesn't accept same notifier registered twice. If so, it will be wrong when adding/removing the element from the list. For example, on one SandyBridge platform, remove module sb_edac and then trigger one error, it will hit oops because it has no mce decoder registered but related notifier_chain still points to an invalid callback function.

McKenney: " This series has four patches, the major point of which is to eliminate some slowdowns (including boot-time slowdowns) resulting from some RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers from the idle loop has no effect if the CPU has entered dyntick-idle mode because the CPU has already computed its wakeup time, and posting a timer does not cause it to be recomputed. The short-term fix is for RCU to precompute the timeout value so that the CPU's calculation is correct. " Signed-off-by: Ingo Molnar <mingo@kernel.org>
2012-06-11dummy: fix rcu_sched self-detected stallsEric Dumazet
Trying to "modprobe dummy numdummies=30000" triggers : INFO: rcu_sched self-detected stall on CPU { 8} (t=60000 jiffies) After this splat, RTNL is locked and reboot is needed. We must call cond_resched() to avoid this, even holding RTNL. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-06-11clocksource: sh_tmu: Use clockevents_config_and_register().Paul Mundt
This switches over to the now exported clockevents_config() and clockevents_config_and_register() helpers. This knocks off a long-standing TMU TODO item. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-06-11net: Reorder initialization in ip_route_output to fix gcc warningRoland Dreier
If I build with W=1, for every file that includes <net/route.h>, I get the warning include/net/route.h: In function 'ip_route_output': include/net/route.h:135:3: warning: initialized field overwritten [-Woverride-init] include/net/route.h:135:3: warning: (near initialization for 'fl4') [-Woverride-init] (This is with "gcc (Debian 4.6.3-1) 4.6.3") A fix seems pretty trivial: move the initialization of .flowi4_tos earlier. As far as I can tell, this has no effect on code generation. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-11bug.h: need linux/kernel.h for TAINT_WARN.Paul Mundt
asm-generic/bug.h uses taint flags that are only defined in linux/kernel.h, resulting in build failures on platforms that don't include linux/kernel.h some other way: arch/sh/include/asm/thread_info.h:172:2: error: 'TAINT_WARN' undeclared (first use in this function) Caused by commit edd63a2763bd ("set_restore_sigmask() is never called without SIGPENDING (and never should be)").

2012-06-11ASoC: wm8904: Fix cache only managementMark Brown
We should be using the regmap API consistently for all the cache only configuration and we should be going cache only before we power down the supplies. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-11ASoC: wm8904: Fix GPIO and MICBIAS initialisation for regmap conversionMark Brown
We no longer have a flat ASoC cache so can't peer directly into the array any more but should instead use the register I/O functions to update the cache. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org (v3.4)
2012-06-11ASoC: fix pxa-ssp compiling issue under mach-mmpQiao Zhou
pxa-ssp.c uses API like cpu_is_pxa3xx(), cpu_is_pxa2xx(), which is defined under arch-pxa architecture, and drivers under mach-mmp can't find it. so just use ssp->type to replace that API.
