It was only ever used by the ACPI video driver, and that only use case vanished over 3 years ago (see commit 677bd810, "ACPI video: remove output switching control".)

2014-03-19ACPI / button: Add ACPI Button event via netlink routineLan Tianyu
Commit 1696d9d (ACPI: Remove the old /proc/acpi/event interface) removed ACPI Button event which originally was sent to userspace via /proc/acpi/event. This caused ACPI shutdown regression on gentoo in VirtualBox. Now ACPI events are sent to userspace via netlink, so add ACPI Button event back via netlink routine.

2014-03-19ACPI / AC: recheck adapter status upon battery status changesAlexander Mezin
On HP Pavilion dv6-6179er there are no notifications when AC adapter is plugged/unplugged. However, when AC status is read (acpi_ac_get_state), and if AC status has changed, AML code triggers the notification. This patch solves the problem by re-reading AC adapter status upon ACPI_BATTERY_NOTIFY_STATUS notification.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 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.

2014-03-13ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep statesRafael J. Wysocki
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.

2014-03-13eth: fec: Fix lost promiscuous mode after reconnecting cableStefan Wahren
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.

If running on a gb-object capable device with a non-gb capable surface exporter (X server) and a gb capable surface referencing client (GL driver), the referencing client expects to find a shareable backing buffer attached to the surface at reference time. This may not be the case if the surface has not yet been validated. This would cause the surface reference IOCTL to return an error.

2014-03-13cpufreq: Skip current frequency initialization for ->setpolicy driversRafael J. Wysocki
After commit da60ce9f2fac (cpufreq: call cpufreq_driver->get() after calling ->init()) __cpufreq_add_dev() sometimes fails for CPUs handled by intel_pstate, because that driver may return 0 from its ->get() callback if it has not run long enough to collect enough samples on the given CPU. That didn't happen before commit da60ce9f2fac which added policy->cur initialization to __cpufreq_add_dev() to help reduce code duplication in other cpufreq drivers. However, the code added by commit da60ce9f2fac need not be executed for cpufreq drivers having the ->setpolicy callback defined, because the subsequent invocation of cpufreq_set_policy() will use that callback to initialize the policy anyway and it doesn't need policy->cur to be initialized upfront. The analogous code in cpufreq_update_policy() is also unnecessary for cpufreq drivers having ->setpolicy set and may be skipped for them as well. Since intel_pstate provides ->setpolicy, skipping the upfront policy->cur initialization for cpufreq drivers with that callback set will cover intel_pstate and the problem it's been having after commit da60ce9f2fac will be addressed.

2014-03-12dm cache: fix access beyond end of origin deviceHeinz Mauelshagen
In order to avoid wasting cache space a partial block at the end of the origin device is not cached. Unfortunately, the check for such a partial block at the end of the origin device was flawed. Fix accesses beyond the end of the origin device that occured due to attempted promotion of an undetected partial block by: - initializing the per bio data struct to allow cache_end_io to work properly - recognizing access to the partial block at the end of the origin device - avoiding out of bounds access to the discard bitset Otherwise, users can experience errors like the following: attempt to access beyond end of device dm-5: rw=0, want=20971520, limit=20971456 ... device-mapper: cache: promotion failed; couldn't copy block Signed-off-by: Heinz Mauelshagen <heinzm@redhat.com> Acked-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org
2014-03-12dm cache: fix truncation bug when copying a block to/from >2TB fast deviceHeinz Mauelshagen
During demotion or promotion to a cache's >2TB fast device we must not truncate the cache block's associated sector to 32bits. The 32bit temporary result of from_cblock() caused a 32bit multiplication when calculating the sector of the fast device in issue_copy_real(). Use an intermediate 64bit type to store the 32bit from_cblock() to allow for proper 64bit multiplication. Here is an example of how this bug manifests on an ext4 filesystem: EXT4-fs error (device dm-0): ext4_mb_generate_buddy:756: group 17136, 32768 clusters in bitmap, 30688 in gd; block bitmap corrupt.

2014-03-12PCI: Don't check resource_size() in pci_bus_alloc_resource()Bjorn Helgaas
Paul reported that after f75b99d5a77d ("PCI: Enforce bus address limits in resource allocation") on a 32-bit kernel (CONFIG_PHYS_ADDR_T_64BIT not set), intel-gtt complained "can't ioremap flush page - no chipset flushing". In addition, other PCI resource allocations, e.g., for bridge windows, failed. This happens because we incorrectly skip bus resources of [mem 0x00000000-0xffffffff] because we think they are of size zero. When resource_size_t is 32 bits wide, resource_size() on [mem 0x00000000-0xffffffff] returns 0 because (r->end - r->start + 1) overflows. Therefore, we can't use "resource_size() == 0" to decide that allocation from this resource will fail. allocate_resource() should fail anyway if it can't satisfy the address constraints, so we should just depend on that. A [mem 0x00000000-0xffffffff] bus resource is obviously not really valid, but we do fall back to it as a default when we don't have information about host bridge apertures.

2014-03-12PCI: Enable INTx in pci_reenable_device() only when MSI/MSI-X not enabledBjorn Helgaas
Andreas reported that after 1f42db786b14 ("PCI: Enable INTx if BIOS left them disabled"), pciehp surprise removal stopped working. This happens because pci_reenable_device() on the hotplug bridge (used in the pciehp_configure_device() path) clears the Interrupt Disable bit, which apparently breaks the bridge's MSI hotplug event reporting. Previously we cleared the Interrupt Disable bit in do_pci_enable_device(), which is used by both pci_enable_device() and pci_reenable_device(). But we use pci_reenable_device() after the driver may have enabled MSI or MSI-X, and we *set* Interrupt Disable as part of enabling MSI/MSI-X. This patch clears Interrupt Disable only when MSI/MSI-X has not been enabled.
