Pull more power management and ACPI updates from Rafael Wysocki: - Fix for a recent cpufreq regression that caused WARN() to trigger overzealously in a couple of places and spam the kernel log with useless garbage as a result. From Viresh Kumar. - ACPI dock fix removing a discrepancy between the definition of acpi_dock_init(), which says that the function returns int, and its header in the header file, which says that it is a void function. The function is now defined as void too. - ACPI PM fix for failures to update device power states as needed, for example, during resume from system suspend, because the old state was deeper than the new one, but the new one is not D0. - Fix for two debug messages in the ACPI power resources code that don't have a newline at the end and make the kernel log difficult to read. From Mika Westerberg. - Two ACPI cleanups from Naresh Bhat and Haicheng Li. - cpupower updates from Thomas Renninger, including Intel Haswell support improvements and a new idle-set subcommand among other things. * tag 'pm+acpi-3.11-rc1-more' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / power: add missing newline to debug messages cpupower: Add Haswell family 0x45 specific idle monitor to show PC8,9,10 states cpupower: Haswell also supports the C-states introduced with SandyBridge cpupower: Introduce idle-set subcommand and C-state enabling/disabling cpupower: Implement disabling of cstate interface cpupower: Make idlestate usage unsigned ACPI / fan: Initialize acpi_state variable ACPI / scan: remove unused LIST_HEAD(acpi_device_list) ACPI / dock: Actually define acpi_dock_init() as void ACPI / PM: Fix corner case in acpi_bus_update_power() cpufreq: Fix serialization of frequency transitions

perf tools: Fix -ldw/-lelf link test when static linking

2013-07-10T16:41:12Z

Since libelf sometimes uses libpthread, we have to list that after -lelf when someone tries to build statically. Else things go boom: Makefile:479: *** No libelf.h/libelf found, please install \ libelf-dev/elfutils-libelf-devel. Stop. Similarly, the -ldw test fails as it often uses -lz: Makefile:462: No libdw.h found or old libdw.h found or elfutils is older \ than 0.138, disables dwarf support. Please install new elfutils-devel/libdw-dev And if we add debugging to try-cc, we see: + echo '#include int main(void) { Dwarf *dbg = dwarf_begin(0, DWARF_C_READ); return (long)dbg; }' + i686-pc-linux-gnu-gcc -x c - -O2 -pipe -march=atom -mtune=atom -mfpmath=sse -g \ -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE \ -ldw -lelf -static -lpthread -lrt -lelf -lm -o .24368 /usr/lib/libdw.a(dwarf_begin_elf.o):function check_section.isra.1: error: undefined reference to 'inflateInit_' /usr/lib/libdw.a(dwarf_begin_elf.o):function check_section.isra.1: error: undefined reference to 'inflate' /usr/lib/libdw.a(dwarf_begin_elf.o):function check_section.isra.1: error: undefined reference to 'inflateReset' /usr/lib/libdw.a(dwarf_begin_elf.o):function check_section.isra.1: error: undefined reference to 'inflateEnd' + echo '#include int main(void) { Elf *elf = elf_begin(0, ELF_C_READ, 0); return (long)elf; }' + i686-pc-linux-gnu-gcc -x c - -O2 -pipe -march=atom -mtune=atom -mfpmath=sse -g \ -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE \ -static -lpthread -lrt -lelf -lm -o .19216 /usr/lib/libelf.a(elf_begin.o):function file_read_elf: error: undefined reference to 'pthread_rwlock_init' /usr/lib/libelf.a(elf_begin.o):function __libelf_read_mmaped_file: error: undefined reference to 'pthread_rwlock_init' /usr/lib/libelf.a(elf_begin.o):function __libelf_read_mmaped_file: error: undefined reference to 'pthread_rwlock_init' /usr/lib/libelf.a(elf_begin.o):function read_file: error: undefined reference to 'pthread_rwlock_init' /usr/lib/libelf.a(elf_begin.o):function lock_dup_elf.8072: error: undefined reference to 'pthread_rwlock_unlock' /usr/lib/libelf.a(elf_begin.o):function lock_dup_elf.8072: error: undefined reference to 'pthread_rwlock_wrlock' /usr/lib/libelf.a(elf_begin.o):function elf_begin: error: undefined reference to 'pthread_rwlock_rdlock' /usr/lib/libelf.a(elf_begin.o):function elf_begin: error: undefined reference to 'pthread_rwlock_unlock' Signed-off-by: Mike Frysinger Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1368073064-18276-1-git-send-email-vapier@gentoo.org Signed-off-by: Arnaldo Carvalho de Melo

2013-07-10T01:24:39Z

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

perf tools: Revert regression in configuration of Python support

2013-07-09T20:29:01Z

Among other things, the following: commit 31160d7feab786c991780d7f0ce2755a469e0e5e Date: Tue Jan 8 16:22:36 2013 -0500 perf tools: Fix GNU make v3.80 compatibility issue attempts to aid the user by tapping into an existing error message, as described in the commit message: ... Also fix an issue where _get_attempt was called with only one argument. This prevented the error message from printing the name of the variable that can be used to fix the problem. or more precisely: -$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2))) +$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2),$(1))) However, The "missing" argument was in fact missing on purpose; it's absence is a signal that the error message should be skipped, because the failure would be due to the default value, not any user-supplied value. This can be seen in how `_ge_attempt' uses `gea_err' (in the config/utilities.mak file): _ge_attempt = $(if $(get-executable),$(get-executable),$(_gea_warn)$(call _gea_err,$(2))) _gea_warn = $(warning The path '$(1)' is not executable.) _gea_err = $(if $(1),$(error Please set '$(1)' appropriately)) That is, because the argument is no longer missing, the value `$(1)' (associated with `_gea_err') always evaluates to true, thus always triggering the error condition that is meant to be reserved for only the case when a user explicitly supplies an invalid value. Concretely, the result is a regression in the Makefile's configuration of python support; rather than gracefully disable support when the relevant executables cannot be found according to default values, the build process halts in error as though the user explicitly supplied the values. This new commit simply reverts the offending one-line change.
