2016-05-11KVM: remove NULL return path for vcpu ids >= KVM_MAX_VCPUSGreg Kurz
Commit c896939f7cff ("KVM: use heuristic for fast VCPU lookup by id") added a return path that prevents vcpu ids to exceed KVM_MAX_VCPUS. This is a problem for powerpc where vcpu ids can grow up to 8*KVM_MAX_VCPUS. This patch simply reverses the logic so that we only try fast path if the vcpu id can be tried as an index in kvm->vcpus[]. The slow path is not affected by the change.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/ARM Changes for Linux v4.7 Reworks our stage 2 page table handling to have page table manipulation macros separate from those of the host systems as the underlying hardware page tables can be configured to be noticably different in layout from the stage 1 page tables used by the host. Adds 16K page size support based on the above. Adds a generic firmware probing layer for the timer and GIC so that KVM initializes using the same logic based on both ACPI and FDT. Finally adds support for hardware updating of the access flag.

2016-05-11gre: do not keep the GRE header around in collect medata modeJiri Benc
For ipgre interface in collect metadata mode, it doesn't make sense for the interface to be of ARPHRD_IPGRE type. The outer header of received packets is not needed, as all the information from it is present in metadata_dst. We already don't set ipgre_header_ops for collect metadata interfaces, which is the only consumer of mac_header pointing to the outer IP header. Just set the interface type to ARPHRD_NONE in collect metadata mode for ipgre (not gretap, that still correctly stays ARPHRD_ETHER) and reset mac_header.

2016-05-11openvswitch: Fix cached ct with helper.Joe Stringer
When using conntrack helpers from OVS, a common configuration is to perform a lookup without specifying a helper, then go through a firewalling policy, only to decide to attach a helper afterwards. In this case, the initial lookup will cause a ct entry to be attached to the skb, then the later commit with helper should attach the helper and confirm the connection. However, the helper attachment has been missing. If the user has enabled automatic helper attachment, then this issue will be masked as it will be applied in init_conntrack(). It is also masked if the action is executed from ovs_packet_cmd_execute() as that will construct a fresh skb. This patch fixes the issue by making an explicit call to try to assign the helper if there is a discrepancy between the action's helper and the current skb->nfct.

2016-05-11ALSA: firewire-lib: drop skip argument from helper functions to queue a packetTakashi Sakamoto
On most of audio and music units on IEEE 1394 bus which ALSA firewire stack supports (or plans to support), CIP with two quadlets header is used. Thus, there's no cases to queue packets with blank payload. If such packets are going to be queued, it means that they're for skips of the cycle. This commit simplifies helper functions to queue a packet.

2016-05-11ALSA: firewire-lib: add context information to tracepointsTakashi Sakamoto
In current implementation, packet processing is done in both of software IRQ contexts of IR/IT contexts and process contexts. This is usual interrupt handling of IR/IT context for 1394 OHCI. (in hardware IRQ context) irq_handler() (drivers/firewire/ohci.c) ->tasklet_schedule() (in software IRQ context) handle_it_packet() or handle_ir_packet_per_buffer() (drivers/firewire/ohci.c) ->flush_iso_completions() ->struct fw_iso_context.callback.sc() = out_stream_callback() or in_stream_callback() However, we have another chance for packet processing. It's done in PCM frame handling via ALSA PCM interfaces. (in process context) ioctl(i.e. SNDRV_PCM_IOCTL_HWSYNC) ->snd_pcm_hwsync() (sound/core/pcm_native.c) ->snd_pcm_update_hw_ptr() (sound/core/pcm_lib.c) ->snd_pcm_update_hw_ptr0() ->struct snd_pcm_ops.pointer() = amdtp_stream_pcm_pointer() ->fw_iso_context_flush_completions() (drivers/firewire/core-iso.c) ->struct fw_card_driver.flush_iso_completions() = ohci_flush_iso_completions() (drivers/firewire/ohci.c) ->flush_iso_completions() ->struct fw_iso_context.callback.sc() = out_stream_callback() or in_stream_callback() This design is for a better granularity of PCM pointer. When ioctl(2) is executed with some commands for ALSA PCM interface, queued packets are handled at first. Then, the latest number of handled PCM frames is reported. The number can represent PCM frames transferred in most near isochronous cycle. Current tracepoints include no information to distinguish running contexts. When tracing the interval of software IRQ context, this is not good. This commit adds more information for current context.

2016-05-11ALSA: firewire-lib: permit to flush queued packets only in process context ↵Takashi Sakamoto
for better PCM period granularity These three commits were merged to improve PCM pointer granularity. commit 76fb87894828 ("ALSA: firewire-lib: taskletize the snd_pcm_period_elapsed() call") commit e9148dddc3c7 ("ALSA: firewire-lib: flush completed packets when reading PCM position") commit 92b862c7d685 ("ALSA: firewire-lib: optimize packet flushing") The point of them is to handle queued packets not only in software IRQ context of IR/IT contexts, but also in process context. As a result of handling packets, period tasklet is scheduled when acrossing PCM period boundary. This is to prevent recursive call of 'struct snd_pcm_ops.pointer()' in the same context. When the pointer callback is executed in the process context, it's better to avoid the second callback in the software IRQ context. The software IRQ context runs immediately after scheduled in the process context because few packets are queued yet. For the aim, 'pointer_flush' is used, however it causes a race condition between the process context and software IRQ context of IR/IT contexts. Practically, this race is not so critical because it influences process context to skip flushing queued packet and to get worse granularity of PCM pointer. The race condition is quite rare but it should be improved for stable service. The similar effect can be achieved by using 'in_interrupt()' macro. This commit obsoletes 'pointer_flush' with it.

2016-05-11x86/extable: ensure entries are swapped completely when sortingMathias Krause
The x86 exception table sorting was changed in commit 29934b0fb8ff ("x86/extable: use generic search and sort routines") to use the arch independent code in lib/extable.c. However, the patch was mangled somehow on its way into the kernel from the last version posted at [1]. The committed version kind of attempted to incorporate the changes of commit 548acf19234d ("x86/mm: Expand the exception table logic to allow new handling options") as in _completely_ _ignoring_ the x86 specific 'handler' member of struct exception_table_entry. This effectively broke the sorting as entries will only partly be swapped now. Fortunately, the x86 Kconfig selects BUILDTIME_EXTABLE_SORT, so the exception table doesn't need to be sorted at runtime. However, in case that ever changes, we better not break the exception table sorting just because of that. [ Ard Biesheuvel points out that BUILDTIME_EXTABLE_SORT applies to the core image only, but we still rely on the sorting routines for modules in that case - Linus ] Fix this by providing a swap_ex_entry_fixup() macro that takes care of the 'handler' member.
