git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Two more fixes: The first one was reported by Mauro Carvalho Chehab, where if a poll() is done against a trace buffer for a CPU that has never been online, it will crash the kernel, as buffers are only created when a CPU comes on line, but the trace files are for all possible CPUs. This fix is to check if the buffer was allocated and if not return -EINVAL. That was the simple fix, the real fix is a bit more complex and not for a -rc release. We could have the files created when the CPUs come online. That would require some design changes. The second one was reported by Peter Zijlstra. If the kernel command line has ftrace=nop, it will lock up the system on boot up. This is because the new design for 3.10 has the nop tracer bootstrap the tracing subsystem. When ftrace=<trace> is defined, when a that tracer is registered, it starts the tracing, but uses the nop tracer to clear things out. What happened here was that ftrace=nop caused the registering of nop to start it and use nop before it was initialized. The only thing nop needs to have done to initialize it is to have the tracer point its current_tracer structure member to the nop tracer. Doing that before registering the nop tracer makes everything work." * tag 'trace-fixes-v3.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Do not poll non allocated cpu buffers tracing: Fix crash when ftrace=nop on the kernel command line

2013-05-28ring-buffer: Do not poll non allocated cpu buffersSteven Rostedt (Red Hat)
The tracing infrastructure sets up for possible CPUs, but it uses the ring buffer polling, it is possible to call the ring buffer polling code with a CPU that hasn't been allocated. This will cause a kernel oops when it access a ring buffer cpu buffer that is part of the possible cpus but hasn't been allocated yet as the CPU has never been online.

2013-05-28ARM: mvebu: Fix bug in coherency fabric low level init functionNadav Haklai
When adding CPU to the SMP group and enabling the coherency on this CPU we must protect the register access. The previous implementation claims to be atomic but doesn't provide any protection against parallel access to the coherency fabric control and configuration registers. This patch fixes this by using the ldrex and strex mechanism. This method should be used in all accesses to those registers.

2013-05-28ARM: Kirkwood: TS219: Fix crash by double PCIe instantiationAndrew Lunn
When creating the DT based boards-ts219.c the none DT ts219-setup.c was used as a template. This includes a lateinit() call to initialize the PCIe bus. The code makes use of machine_is_ts219() which is never true on DT, so a FIXME was added and the code left as is. This was unproblematic until b73690c8f8b5d: "ARM: Kirkwood: Support basic hotplug for PCI-E" which changes the way the PCIe bus is initialized. The non-DT ts219-setup.c now crashes during boot. The lateinit() call in the DT boards-ts219.c is being called, machine_is_ts219() is true and so the PCIe is initialized a second time. This patch removes the useless, and now clearly dangerous, code from boards-ts219.c, making ts219-setup.c work again.

2013-05-28tick: Cure broadcast false positive pending bit warningThomas Gleixner
commit 26517f3e (tick: Avoid programming the local cpu timer if broadcast pending) added a warning if the cpu enters broadcast mode again while the pending bit is still set. Meelis reported that the warning triggers. There are two corner cases which have been not considered: 1) cpuidle calls clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) twice. That can result in the following scenario CPU0 CPU1 cpuidle_idle_call() clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) set cpu in tick_broadcast_oneshot_mask broadcast interrupt event expired for cpu1 set pending bit acpi_idle_enter_simple() clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_ENTER) WARN_ON(pending bit) Move the WARN_ON into the section where we enter broadcast mode so it wont provide false positives on the second call. 2) safe_halt() enables interrupts, so a broadcast interrupt can be delivered befor the broadcast mode is disabled. That sets the pending bit for the CPU which receives the broadcast interrupt. Though the interrupt is delivered right away from the broadcast handler and leaves the pending bit stale. Clear the pending bit for the current cpu in the broadcast handler.

2013-05-27ipv4: fix redirect handling for TCP packetsMichal Kubecek
Unlike ipv4_redirect() and ipv4_sk_redirect(), ip_do_redirect() doesn't call __build_flow_key() directly but via ip_rt_build_flow_key() wrapper. This leads to __build_flow_key() getting pointer to IPv4 header of the ICMP redirect packet rather than pointer to the embedded IPv4 header of the packet initiating the redirect. As a result, handling of ICMP redirects initiated by TCP packets is broken. Issue was introduced by 4895c771c ("ipv4: Add FIB nexthop exceptions.")

The _XFER stack element size was set too small, 8 bytes, when it needs to be 16 bytes. As _XFER is the last stack element used by these implementations, the 16 byte stores with 'movdqa' corrupt the stack where the value of register %r12 is temporarily stored. As these implementations align the stack pointer to 16 bytes, this corruption did not happen every time. Patch corrects this issue.

This patch fixes a bug introduced in the v3.10 merge window. The AB8500 External Regulator driver has recently landed upstream, which registers each of the 3 external regulators located on the AB8500. If these regulators are marked as 'always on', there is a potential for power-loss. If they're not and are seemingly unused the Regulator subsystem will attempt to disable them to save power. This causes an issue for AUX1, AUX2 and AUX3 as they obtain their power from EXT3. So we're specifying that here to prevent EXT3 from being powered down.

2013-05-27mac80211: close AP_VLAN interfaces before unregistering allJohannes Berg
Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces") there's a bug in mac80211 when it unregisters with AP_VLAN interfaces up. If the AP_VLAN interface was registered after the AP it belongs to (which is the typical case) and then we get into this code path, unregister_netdevice_many() will crash because it isn't prepared to deal with interfaces being closed in the middle of it. Exactly this happens though, because we iterate the list, find the AP master this AP_VLAN belongs to and dev_close() the dependent VLANs. After this, unregister_netdevice_many() won't pick up the fact that the AP_VLAN is already down and will do it again, causing a crash.

2013-05-27mac80211: assign AP_VLAN hw queues correctlyJohannes Berg
A lot of code in mac80211 assumes that the hw queues are set up correctly for all interfaces (except for monitor) but this isn't true for AP_VLAN interfaces. Fix this by copying the AP master configuration when an AP VLAN is brought up, after this the AP interface can't change its configuration any more and needs to be brought down to change it, which also forces AP_VLAN interfaces down, so just copying in open() is sufficient.

2013-05-27s390/smp: lost IPIs on cpu hotplugHeiko Carstens
IPIs might be lost when a cpu gets brought offline: When stop_machine executes its state machine there is a race window for the state STOPMACHINE_DISABLE_IRQ where the to be brought offline cpu might already have irqs disabled but a different cpu still may have irqs enabled. If the enabled cpu receives an interrupt and as a result sends an IPI to the to be offlined cpu in its bottom halve context, the IPI won't be noticed before the cpu is offline. In fact the race window is much larger since there is no guarantee when an IPI will be received. To fix this check for enqueued but not yet received IPIs in the cpu_disable() path and call the respective handlers before the cpu is marked offline.
