      Pull ACPI and power management fixes from Rafael Wysocki:
       "Three of these are regression fixes, for two recent regressions and
        one introduced during the 3.13 cycle, and the fourth one is a working
        version of the fix that had to be reverted last time.
      
        Specifics:
      
         - A recent ACPI resources handling fix overlooked the fact that it
           had to update the ACPI PNP subsystem's resources parsing too and
           caused confusing warning messages to be printed during system
           intialization on some systems (with arguably buggy ACPI tables).
           Fix from Zhang Rui.
      
         - Moving the early ACPI initialization before timekeeping_init()
           earlier in this cycle broke fast TSC calibration on at least one
           system, so it needs to be done later, but still before
           efi_enter_virtual_mode() to allow the EFI initialization to refer
           to ACPI.
      
         - A change related to code duplication reduction in the cpufreq core
           inadvertently caused cpufreq intialization to fail for some CPUs
           handled by intel_pstate by adding checks that may fail for that
           driver, but aren't even necessary when it is used.  The issue is
           addressed by preventing those checks from run in the configurations
           in which they aren't needed.
      
         - If the Hardware Reduced ACPI flag is set in the ACPI tables, system
           suspend, hibernation and ACPI power off will only work when special
           sleep control and sleep status registeres are provided (their
           addresses in the ACPI tables are not zero).  If those registers are
           not available, the features in question have no chances to work, so
           they shouldn't even be regarded as supported.  That helps with
           power off in particular, because alternative power off methods may
           be used then and they may actually work"

      Pull networking fixes from David Miller:
       "I know this is a bit more than you want to see, and I've told the
        wireless folks under no uncertain terms that they must severely scale
        back the extent of the fixes they are submitting this late in the
        game.
      
        Anyways:
      
         1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
            is the correct implementation, like it should.  Instead it does
            something like a NAPI poll operation.  This leads to crashes.
      
            From Neil Horman and Arnd Bergmann.
      
         2) Segmentation of SKBs requires proper socket orphaning of the
            fragments, otherwise we might access stale state released by the
            release callbacks.
      
            This is a 5 patch fix, but the initial patches are giving
            variables and such significantly clearer names such that the
            actual fix itself at the end looks trivial.
      
            From Michael S.  Tsirkin.
      
         3) TCP control block release can deadlock if invoked from a timer on
            an already "owned" socket.  Fix from Eric Dumazet.
      
         4) In the bridge multicast code, we must validate that the
            destination address of general queries is the link local all-nodes
            multicast address.  From Linus Lüssing.
      
         5) The x86 BPF JIT support for negative offsets puts the parameter
            for the helper function call in the wrong register.  Fix from
            Alexei Starovoitov.
      
         6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
            r8169 driver is incorrect.  Fix from Hayes Wang.
      
         7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
            if a packet is a GSO frame, but that's not the correct test.  It
            should use skb_is_gso(skb) instead.  Fix from Wei Liu.
      
         8) Negative msg->msg_namelen values should generate an error, from
            Matthew Leach.
      
         9) at86rf230 can deadlock because it takes the same lock from it's
            ISR and it's hard_start_xmit method, without disabling interrupts
            in the latter.  Fix from Alexander Aring.
      
        10) The FEC driver's restart doesn't perform operations in the correct
            order, so promiscuous settings can get lost.  Fix from Stefan
            Wahren.
      
        11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.
      
        12) Reference count and memory leak fixes in TIPC from Ying Xue and
            Erik Hugne.
      
        13) Forced eviction in inet_frag_evictor() must strictly make sure all
            frags are deleted, otherwise module unload (f.e.  6lowpan) can
            crash.  Fix from Florian Westphal.
      
        14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
            uses as a hash function), which breaks on PowerPC.  From Anton
            Blanchard.
      
            The main gist of the issue is that csum_partial() is defined only
            as a value that, once folded (f.e.  via csum_fold()) produces a
            correct 16-bit checksum.  It is legitimate, therefore, for
            csum_partial() to produce two different 32-bit values over the
            same data if their respective alignments are different.
      
        15) Fix endiannes bug in MAC address handling of ibmveth driver, also
            from Anton Blanchard.
      
        16) Error checks for ipv6 exthdrs offload registration are reversed,
            from Anton Nayshtut.
      
        17) Externally triggered ipv6 addrconf routes should count against the
            garbage collection threshold.  Fix from Sabrina Dubroca.
      
        18) The PCI shutdown handler added to the bnx2 driver can wedge the
            chip if it was not brought up earlier already, which in particular
            causes the firmware to shut down the PHY.  Fix from Michael Chan.
      
        19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
            currently coded it can and does trigger in legitimate situations.
            From Eric Dumazet.
      
        20) BNA driver fails to build on ARM because of a too large udelay()
            call, fix from Ben Hutchings.
      
        21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
            from Eric Dumazet.
      
        22) The vlan passthrough ops added in the previous release causes a
            regression in source MAC address setting of outgoing headers in
            some circumstances.  Fix from Peter Boström"

      ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep states · a4e90bed
      Rafael J. Wysocki 提交于
      If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
      the optional sleep control and sleep status registers for making
      the system enter sleep states (including S5), so it is not possible
      to use system sleep states or power it off using ACPI if the HW
      Reduced ACPI mode bit is set and those registers are not available.
      
      For this reason, add a new function, acpi_sleep_state_supported(),
      checking if the HW Reduced ACPI mode bit is set and whether or not
      system sleep states are usable in that case in addition to checking
      the return value of acpi_get_sleep_type_data() and make the ACPI
      sleep setup routines use that function to check the availability of
      system sleep states.
      
      Among other things, this prevents the kernel from attempting to
      use ACPI for powering off HW Reduced ACPI systems without the sleep
      control and sleep status registers, because ACPI power off doesn't
      have a chance to work on them.  That allows alternative power off
      mechanisms that may actually work to be used on those systems.  The
      affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
      Desktop SDP and Ivy Bridge EP Demo depot.

      ipv6: Avoid unnecessary temporary addresses being generated · ecab6701
      Heiner Kallweit 提交于
      tmp_prefered_lft is an offset to ifp->tstamp, not now. Therefore
      age needs to be added to the condition.
      
      Age calculation in ipv6_create_tempaddr is different from the one
      in addrconf_verify and doesn't consider ADDRCONF_TIMER_FUZZ_MINUS.
      This can cause age in ipv6_create_tempaddr to be less than the one
      in addrconf_verify and therefore unnecessary temporary address to
      be generated.
      Use age calculation as in addrconf_modify to avoid this.

      If the Freescale fec is in promiscuous mode and network cable is
      reconnected then the promiscuous mode get lost. The problem is caused
      by a too soon call of set_multicast_list to re-enable promisc mode.
      The FEC_R_CNTRL register changes are overwritten by fec_restart.
