git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf updates from Ingo Molnar: "Kernel side changes: - Add Intel RAPL energy counter support (Stephane Eranian) - Clean up uprobes (Oleg Nesterov) - Optimize ring-buffer writes (Peter Zijlstra) Tooling side changes, user visible: - 'perf diff': - Add column colouring improvements (Ramkumar Ramachandra) - 'perf kvm': - Add guest related improvements, including allowing to specify a directory with guest specific /proc information (Dongsheng Yang) - Add shell completion support (Ramkumar Ramachandra) - Add '-v' option (Dongsheng Yang) - Support --guestmount (Dongsheng Yang) - 'perf probe': - Support showing source code, asking for variables to be collected at probe time and other 'perf probe' operations that use DWARF information. This supports only binaries with debugging information at this time, detached debuginfo (aka debuginfo packages) support should come in later patches (Masami Hiramatsu) - 'perf record': - Rename --no-delay option to --no-buffering, better reflecting its purpose and freeing up '--delay' to take the place of '--initial-delay', so that 'record' and 'stat' are consistent (Arnaldo Carvalho de Melo) - Default the -t/--thread option to no inheritance (Adrian Hunter) - Make per-cpu mmaps the default (Adrian Hunter) - 'perf report': - Improve callchain processing performance (Frederic Weisbecker) - Retain bfd reference to lookup source line numbers, greatly optimizing, among other use cases, 'perf report -s srcline' (Adrian Hunter) -

This tree adds a third panic_timeout configuration method: configuration via Kconfig, via CONFIG_PANIC_TIMEOUT=X - useful to distros that generally want their kernel defaults to come with the .config.

2014-01-20mmc: sdhci-pci: Fix BYT sd card getting stuck in runtime suspendAdrian Hunter
A host controller for a SD card may need a GPIO for card detect in order to wake up from runtime suspend when a card is inserted. If that GPIO is not configured, then the host controller will not wake up. Fix that for the affected devices by not enabling runtime PM unless the GPIO is successfully set up. This affects BYT sd card host controller which had runtime PM enabled from v3.11. For completeness, the MFD sd card host controller is flagged also. The original patch before rebasing (see link below) was tested on v3.11.10 and v3.12.4 although the patch applied with some offsets and fuzz.

2014-01-20KVM: s390: Fix memory access error detectionChristian Borntraeger
Seems that commit 210b1607012cc9034841a393e0591b2c86d9e26c (KVM: s390: Removed SIE_INTERCEPT_UCONTROL) lost a hunk when we reworked our patch queue to rework the async_fp code. We now ignore faults on the sie instruction (guest accesses non-existing memory) instead of sending a fault into the guest. This leads to hang situations with the old virtio transport that checks for descriptor memory after guest memory. Instead of bailing out this code now goes wild... Lets re-add the check.

2014-01-20iwlwifi: pcie: don't panic on host commands in iwldvmEmmanuel Grumbach
None of the devices supported by iwldvm have support for shadow registers. This means that we wake the NIC when we increment the write pointer on Tx ring. This happened even before my bad commit mentionned below. Since my commit below, we wake up the NIC when we put a host command on the ring regardless of shadow register support. This means that in iwldvm (when the NIC doesn't support shadow register), we wake up the NIC twice: pcie_enqueue_hcmd: wake up the NIC iwl_pcie_txq_inc_wr_ptr: wake up the NIC - no shadow reg support Since waking up the NIC means that we need to acquire a spinlock, this obviously leads to a recursive spinlock and hence a freeze.

2014-01-19net: stmmac: fix NULL pointer dereference in stmmac_get_tx_hwtstampdamuzi000
When timestamping is enabled, stmmac_tx_clean will call stmmac_get_tx_hwtstamp to get tx TS. But the skb can be NULL because the last of its tx_skbuff is NULL if this packet frame is filled in more than one descriptors. To fix the issue, change the code: - Store TX skb to the tx_skbuff[] of frame's last segment. - Check skb is not NULL in stmmac_get_tx_hwtstamp.

2014-01-19net: stmmac: sunxi platform extensions for GMAC in Allwinner A20 SoC'sChen-Yu Tsai
The Allwinner A20 has an ethernet controller that seems to be an early version of Synopsys DesignWare MAC 10/100/1000 Universal, which is supported by the stmmac driver. Allwinner's GMAC requires setting additional registers in the SoC's clock control unit. The exact version of the DWMAC IP that Allwinner uses is unknown, thus the exact feature set is unknown.

2014-01-19net: stmmac: Use driver data and callbacks tied with compatible stringsChen-Yu Tsai
The stmmac driver core allows passing feature flags and callbacks via platform data. Add a similar stmmac_of_data to pass flags and callbacks tied to compatible strings. This allows us to extend stmmac with glue layers for different SoCs. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-19net: stmmac: Deprecate snps, phy-addr and auto-detect PHY addressChen-Yu Tsai
The snps,phy-addr device tree property is non-standard, and should be removed in favor of proper phy node support. Remove it from the binding documents and warn if the property is still used. Most PHYs respond to address 0, but a few don't, so auto-detect PHY address by default, to make up for the lack of explicit address selection.

2014-01-19net: stmmac: Allocate and pass soc/board specific data to callbacksChen-Yu Tsai
The current .init and .exit callbacks requires access to driver private data structures. This is not a good seperation and abstraction.

2014-01-19DT: net: davinci_emac: "phy-handle" property is actually optionalSergei Shtylyov
Though described as required, the "phy-handle" property for the DaVinci EMAC binding is actually optional, as the driver will happily function without it, assuming 100/FULL link; the property is not specified either in the example device node, or in the actual EMAC device nodes for DA850 and AM3517 device trees.

2014-01-19net: fix "queues" uevent between network namespacesWeilong Chen
When I create a new namespace with 'ip netns add net0', or add/remove new links in a namespace with 'ip link add/delete type veth', rx/tx queues events can be got in all namespaces. That is because rx/tx queue ktypes do not have namespace support, and their kobj parents are setted to NULL. This patch is to fix it.

2014-01-19ipv6: optimize link local address searchHannes Frederic Sowa
ipv6_link_dev_addr sorts newly added addresses by scope in ifp->addr_list. Smaller scope addresses are added to the tail of the list. Use this fact to iterate in reverse over addr_list and break out as soon as a higher scoped one showes up, so we can spare some cycles on machines with lot's of addresses. The ordering of the addresses is not relevant and we are more likely to get the eui64 generated address with this change anyway.

2014-01-19ipv6: make IPV6_RECVPKTINFO work for ipv4 datagramsHannes Frederic Sowa
We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data for IPv4 datagrams on IPv6 sockets. This patch splits the ip6_datagram_recv_ctl into two functions, one which handles both protocol families, AF_INET and AF_INET6, while the ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data. ip6_datagram_recv_*_ctl never reported back any errors, so we can make them return void. Also provide a helper for protocols which don't offer dual personality to further use ip6_datagram_recv_ctl, which is exported to modules. I needed to shuffle the code for ping around a bit to make it easier to implement dual personality for ping ipv6 sockets in future.
