2014-05-26PM / sleep: Add state field to pm_states[] entriesRafael J. Wysocki
To allow sleep states corresponding to the "mem", "standby" and "freeze" lables to be different from the pm_states[] indexes of those strings, introduce struct pm_sleep_state, consisting of a string label and a state number, and turn pm_states[] into an array of objects of that type. This modification should not lead to any functional changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2014-05-26ath10k: make core registering asyncMichal Kazior
If ath10k was built into the kernel it could stall booting for 120 seconds by default (60 seconds for each firmware API variant) waiting for firmware files before userspace was ready or filesystems mounted. Fix this by making the core registering asynchronous. This also shoves off about 1 second from boot time on most systems since the driver is now mostly initialized in a worker and modprobe takes very little time to complete.

2014-05-26mac80211: add a single-transaction driver op to switch contextsLuciano Coelho
In some cases, when the driver is already using all the channel contexts it can handle at once, we have to do an in-place switch (ie. we cannot afford using an extra context temporarily for the transaction). But some drivers may not support switching the channel context assigned to a vif on the fly (ie. without unassigning and assigning it) while others may only work if the context is changed on the fly, without unassigning it first. To allow these different scenarios, add a new driver operation that let's the driver decide how to handle an in-place switch.

2014-05-26ALSA: hda - Add a new quirk match based on default pin configurationDavid Henningsson
Normally, we match on pci ssid only. This works but needs new code for every machine. To catch more machines in the same quirk, let's add a new type of quirk, where we match on 1) PCI Subvendor ID (i e, not device, just vendor) 2) Codec ID 3) Pin configuration default If all these three match, we could be reasonably certain that the quirk should apply to the machine even though it might not be the exact same device.

2014-05-26netfilter: bridge: fix Kconfig unmet dependenciesPablo Neira
Before f5efc69 ("netfilter: nf_tables: Add meta expression key for bridge interface name"), the entire net/bridge/netfilter/ directory depended on BRIDGE_NF_EBTABLES, ie. on ebtables. However, that directory already contained the nf_tables bridge extension that we should allow to compile separately. In f5efc69, we tried to generalize this by using CONFIG_BRIDGE_NETFILTER which was not a good idea since this option already existed and it is dedicated to enable the Netfilter bridge IP/ARP filtering. Let's try to fix this mess by: 1) making net/bridge/netfilter/ dependent on the toplevel CONFIG_NETFILTER option, just like we do with the net/netfilter and net/ipv{4,6}/netfilter/ directories. 2) Changing 'selects' to 'depends on' NETFILTER_XTABLES for BRIDGE_NF_EBTABLES. I believe this problem was already before f5efc69: warning: (BRIDGE_NF_EBTABLES) selects NETFILTER_XTABLES which has unmet direct dependencies (NET && INET && NETFILTER) 3) Fix ebtables/nf_tables bridge dependencies by making NF_TABLES_BRIDGE and BRIDGE_NF_EBTABLES dependent on BRIDGE and NETFILTER: warning: (NF_TABLES_BRIDGE && BRIDGE_NF_EBTABLES) selects BRIDGE_NETFILTER which has unmet direct dependencies (NET && BRIDGE && NETFILTER && INET && NETFILTER_ADVANCED) net/built-in.o: In function `br_parse_ip_options': br_netfilter.c:(.text+0x4a5ba): undefined reference to `ip_options_compile' br_netfilter.c:(.text+0x4a5ed): undefined reference to `ip_options_rcv_srr' net/built-in.o: In function `br_nf_pre_routing_finish': br_netfilter.c:(.text+0x4a8a4): undefined reference to `ip_route_input_noref' br_netfilter.c:(.text+0x4a987): undefined reference to `ip_route_output_flow' make: *** [vmlinux] Error 1 Reported-by: Jim Davis <jim.epost@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.
