In commit 6892b41d Author: Lad, Prabhakar <prabhakar.csengg@gmail.com> Date: Tue Jun 25 21:24:51 2013 +0530 net: davinci: emac: Convert to devm_* api the call of request_irq is replaced by devm_request_irq and the call of free_irq is removed. But since interrupts are requested in emac_dev_open, doing ifconfig up/down on the board requests the interrupts again each time, causing devm_request_irq to fail. The interface is dead until the device is rebooted. This patch reverts said commit partially: It changes the driver back to use request_irq instead of devm_request_irq, puts free_irq back in place, but keeps the remaining changes of the original patch.

The kernel starts out its "jiffies" timer as 5 minutes below zero, as shown in include/linux/jiffies.h: /* * Have the 32 bit jiffies value wrap 5 minutes after boot * so jiffies wrap bugs show up earlier. */ #define INITIAL_JIFFIES ((unsigned long)(unsigned int) (-300*HZ)) The loop in ovs_flow_stats_get() starts out with 'used' set to 0, then takes any "later" time. This means that for the first five minutes after boot, flows will always be reported as never used, since 0 is greater than any time already seen. Signed-off-by:

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" * tag 'pm+acpi-3.14-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep states ACPI / init: Invoke early ACPI initialization later cpufreq: Skip current frequency initialization for ->setpolicy drivers PNP / ACPI: proper handling of ACPI IO/Memory resource parsing failures

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.

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. References: https://bugzilla.kernel.org/show_bug.cgi?id=70931 Reported-by:

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.

The commit d3ab3ffd (bonding: use rlb_client_info->vlan_id instead of ->tag) remove the rlb_client_info->tag, but occur some issues, The vlan_get_tag() will return 0 for success and -EINVAL for error, so the client_info->vlan_id always be set to 0 if the vlan_get_tag return 0 for success, so the client_info would never get a correct vlan id. We should only set the vlan id to 0 when the vlan_get_tag return error.
