2012-03-07hwmon: (zl6100) Maintain delay parameter in driver instance dataGuenter Roeck
A global delay parameter has the side effect of being overwritten with 0 if a single ZL2004 or ZL6105 is instantiated. If other chips supported by the same driver are in the system, this will result in access errors for those chips. To solve the problem, keep a per-instance copy of the delay parameter, and do not change the original parameter.

2012-03-07C6X: fix KSTK_EIP and KSTK_ESP macrosMark Salter
There was a latent typo in the C6X KSTK_EIP and KSTK_ESP macros which caused a problem with a new patch which used them. The broken definitions were of the form: #define KSTK_FOO(tsk) (task_pt_regs(task)->foo) Note the use of task vs tsk. This actually worked before because the only place in the kernel which used these macros passed in a local pointer named task. Signed-off-by: Mark Salter <msalter@redhat.com>
2012-03-07Revert "CPU hotplug, cpusets, suspend: Don't touch cpusets during ↵Linus Torvalds
suspend/resume" This reverts commit 8f2f748b0656257153bcf0941df8d6060acc5ca6. It causes some odd regression that we have not figured out, and it's too late in the -rc series to try to figure it out now. As reported by Konstantin Khlebnikov, it causes consistent hangs on his laptop (Thinkpad x220: 2x cores + HT). They can be avoided by adding calls to "rebuild_sched_domains();" in cpuset_cpu_[in]active() for the CPU_{ONLINE/DOWN_FAILED/DOWN_PREPARE}_FROZEN cases, but it's not at all clear why, and it makes no sense. Konstantin's config doesn't even have CONFIG_CPUSETS enabled, just to make things even more interesting. So it's not the cpusets, it's just the scheduling domains. So until this is understood, revert.

We've been getting occasional oops running a 32-bit kernel on a certain system in our RHEL test hw. It appears that we fail to get sufficent ioremap space for the framebuffer, and this leads to an oops. This patch should fix the oops and leave a message in the logs we can check for.

When disabling a counter on an ARMv7 PMU, we should also clear the overflow flag in case an overflow occurred whilst stopping the counter.

2012-03-07ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling modeWill Deacon
On ARM, the PMU does not stop counting after an overflow and therefore IRQ latency affects the new counter value read by the kernel. This is significant for non-sampling runs where it is possible for the new value to overtake the previous one, causing the delta to be out by up to max_period events. Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency") attempted to fix this problem by allowing interrupt handlers to pass an overflow flag to the event update function, causing the overflow calculation to assume that the counter passed through zero when going from prev to new. Unfortunately, this doesn't work when overflow occurs on the perf_task_tick path because we have the flag cleared and end up computing a large negative delta. This patch removes the overflow flag from armpmu_event_update and instead limits the sample_period to half of the max_period for non-sampling profiling runs.

2012-03-06vm: avoid using find_vma_prev() unnecessarilyLinus Torvalds
Several users of "find_vma_prev()" were not in fact interested in the previous vma if there was no primary vma to be found either. And in those cases, we're much better off just using the regular "find_vma()", and then "prev" can be looked up by just checking vma->vm_prev. The find_vma_prev() semantics are fairly subtle (see Mikulas' recent commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return prev by reference" means that it generates worse code too. Thus this "let's avoid using this inconvenient and clearly too subtle interface when we don't really have to" patch.

2012-03-06mm: fix find_vma_prevMikulas Patocka
Commit 6bd4837de96e ("mm: simplify find_vma_prev()") broke memory management on PA-RISC. After application of the patch, programs that allocate big arrays on the stack crash with segfault, for example, this will crash if compiled without optimization: int main() { char array[200000]; array[199999] = 0; return 0; } The reason is that PA-RISC has up-growing stack and the stack is usually the last memory area. In the above example, a page fault happens above the stack. Previously, if we passed too high address to find_vma_prev, it returned NULL and stored the last VMA in *pprev. After "simplify find_vma_prev" change, it stores NULL in *pprev. Consequently, the stack area is not found and it is not expanded, as it used to be before the change. This patch restores the old behavior and makes it return the last VMA in *pprev if the requested address is higher than address of any other VMA.

2012-03-06bridge: netfilter: don't call iptables on vlan packets if sysctl is offFlorian Westphal
When net.bridge.bridge-nf-filter-vlan-tagged is 0 (default), vlan packets arriving should not be sent to ip(6)tables by bridge netfilter. However, it turns out that we currently always send VLAN packets to netfilter, if .. a), CONFIG_VLAN_8021Q is enabled ; or b), CONFIG_VLAN_8021Q is not set but rx vlan offload is enabled on the bridge port. This is because bridge netfilter treats skb with skb->protocol == ETH_P_IP{V6} as "non-vlan packet". With rx vlan offload on or CONFIG_VLAN_8021Q=y, the vlan header has already been removed here, and we cannot rely on skb->protocol alone. Fix this by only using skb->protocol if the skb has no vlan tag, or if a vlan tag is present and filter-vlan-tagged bridge netfilter sysctl is enabled. We cannot remove the skb->protocol == htons(ETH_P_8021Q) test because the vlan tag is still around in the CONFIG_VLAN_8021Q=n && "ethtool -K $itf rxvlan off" case. reproducer: iptables -t raw -I PREROUTING -i br0 iptables -t raw -I PREROUTING -i br0.1 Then send packets to an ip address configured on br0.1 interface. Even with net.bridge.bridge-nf-filter-vlan-tagged=0, the 1st rule will match instead of the 2nd one. With this patch applied, the 2nd rule will match instead. In the non-local address case, netfilter won't be consulted after this patch unless the sysctl is switched on.

With runtime PM, if the ethernet cable is disconnected, the device is transitioned to D3 state to conserve energy. If the system is shutdown in this state, any register accesses in rtl_shutdown are dropped on the floor. As the device was programmed by .runtime_suspend() to wake on link changes, it is thus brought back up as soon as the link recovers. Resuming every suspended device through the driver core would slow things down and it is not clear how many devices really need it now. Original report and D0 transition patch by Sameer Nanda.

2012-03-06tcp: fix tcp_shift_skb_data() to not shift SACKed data below snd_unaNeal Cardwell
This commit fixes tcp_shift_skb_data() so that it does not shift SACKed data below snd_una. This fixes an issue whose symptoms exactly match reports showing tp->sacked_out going negative since 3.3.0-rc4 (see "WARNING: at net/ipv4/tcp_input.c:3418" thread on netdev). Since 2008 (832d11c5cd076abc0aa1eaf7be96c81d1a59ce41) tcp_shift_skb_data() had been shifting SACKed ranges that were below snd_una. It checked that the *end* of the skb it was about to shift from was above snd_una, but did not check that the end of the actual shifted range was above snd_una; this commit adds that check. Shifting SACKed ranges below snd_una is problematic because for such ranges tcp_sacktag_one() short-circuits: it does not declare anything as SACKed and does not increase sacked_out. Before the fixes in commits cc9a672ee522d4805495b98680f4a3db5d0a0af9 and daef52bab1fd26e24e8e9578f8fb33ba1d0cb412, shifting SACKed ranges below snd_una happened to work because tcp_shifted_skb() was always (incorrectly) passing in to tcp_sacktag_one() an skb whose end_seq tcp_shift_skb_data() had already guaranteed was beyond snd_una. Hence tcp_sacktag_one() never short-circuited and always increased tp->sacked_out in this case. After those two fixes, my testing has verified that shifting SACKed ranges below snd_una could cause tp->sacked_out to go negative with the following sequence of events: (1) tcp_shift_skb_data() sees an skb whose end_seq is beyond snd_una, then shifts a prefix of that skb that is below snd_una (2) tcp_shifted_skb() increments the packet count of the already-SACKed prev sk_buff (3) tcp_sacktag_one() sees the end of the new SACKed range is below snd_una, so it short-circuits and doesn't increase tp->sacked_out (5) tcp_clean_rtx_queue() sees the SACKed skb has been ACKed, decrements tp->sacked_out by this "inflated" pcount that was missing a matching increase in tp->sacked_out, and hence tp->sacked_out underflows to a u32 like 0xFFFFFFFF, which casted to s32 is negative. (6) this leads to the warnings seen in the recent "WARNING: at net/ipv4/tcp_input.c:3418" thread on the netdev list; e.g.: tcp_input.c:3418 WARN_ON((int)tp->sacked_out < 0); More generally, I think this bug can be tickled in some cases where two or more ACKs from the receiver are lost and then a DSACK arrives that is immediately above an existing SACKed skb in the write queue. This fix changes tcp_shift_skb_data() to abort this sequence at step (1) in the scenario above by noticing that the bytes are below snd_una and not shifting them.

2012-03-06vsprintf: make %pV handling compatible with kasprintf()Jan Beulich
kasprintf() (and potentially other functions that I didn't run across so far) want to evaluate argument lists twice. Caring to do so for the primary list is obviously their job, but they can't reasonably be expected to check the format string for instances of %pV, which however need special handling too: On architectures like x86-64 (as opposed to e.g. ix86), using the same argument list twice doesn't produce the expected results, as an internally managed cursor gets updated during the first run. Fix the problem by always acting on a copy of the original list when handling %pV. Signed-off-by: Jan Beulich <jbeulich@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-06page_cgroup: fix horrid swap accounting regressionHugh Dickins
Why is memcg's swap accounting so broken? Insane counts, wrong ownership, unfreeable structures, which later get freed and then accessed after free. Turns out to be a tiny a little 3.3-rc1 regression in 9fb4b7cc0724 "page_cgroup: add helper function to get swap_cgroup": the helper function (actually named lookup_swap_cgroup()) returns an address using void* arithmetic, but the structure in question is a short.

2012-03-06ARM: pxa: fix invalid mfp pin issueHaojian Zhuang
Failure is reported on hx4700 with kernel v3.3-rc1. __mfp_validate: GPIO20 is invalid pin __mfp_validate: GPIO21 is invalid pin __mfp_validate: GPIO15 is invalid pin __mfp_validate: GPIO78 is invalid pin __mfp_validate: GPIO79 is invalid pin __mfp_validate: GPIO80 is invalid pin __mfp_validate: GPIO33 is invalid pin __mfp_validate: GPIO48 is invalid pin __mfp_validate: GPIO49 is invalid pin __mfp_validate: GPIO50 is invalid pin Since pxa_last_gpio is used in mfp-pxa2xx driver. But it's only updated in pxa-gpio driver that run after mfp-pxa2xx driver. So update the pxa_last_gpio first in mfp-pxa2xx driver.

2012-03-06ARM: pxa: remove duplicated registeration on pxa-gpioHaojian Zhuang
Both reboot (via reboot(RB_AUTOBOOT)) and suspend freeze on hx4700. Registration of pxa_gpio_syscore_ops is moved into pxa-gpio driver, but it still exists in arch-pxa directory. It resulsts failure on reboot and suspend. Now remove the registration code in arch-pxa. Reported-by: Paul Parsons <lost.distance@yahoo.com> Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com>
2012-03-06ARM: pxa: add dummy clock for pxa25x and pxa27xHaojian Zhuang
gpio-pxa driver is shared among arch-pxa and arch-mmp. Clock is the essential component on pxa3xx/pxa95x and arch-mmp. So we need to define dummy clock in pxa25x/pxa27x instead. This regression was introduced by the commit "ARM: pxa: add dummy clock for sa1100-rtc", id a55b5adaf403c4d032e0871ad4ee3367782f4db6.
