schedule_timeout takes a timeout in jiffies but the code currently is passing in a constant SDIAS_SLEEP_TICKS, as this is otherwise unused it is replaced by 500ms as recommended by Michael Holzheu <holzheu@linux.vnet.ibm.com> and converted with msecs_to_jiffies(); As SDIAS_SLEEP_TICKS was only used in this one location it is dropped. Patch was compile tested with (s390) defconfig + CONFIG_MARCH_Z10=y, (implies CONFIG_CRASH_DUMP=y) Patch is against 4.1-rc5 (localversion-next is -next-20150529) Link: http://lkml.org/lkml/2015/5/29/235Signed-off-by:

Enabling a DASD that was configured to use the DIAG250 access method while the corresponding kernel module dasd_diag_mod has not been loaded fails with an error message. To fix this, users need to manually load the dasd_diag_mod module. This procedure can be simplified by automatically loading the dasd_diag_mod from within the kernel when a DASD configured for DIAG250 is set online. Signed-off-by:

When compiling the kernel for GCOV (CONFIG_GCOV_KERNEL,-fprofile-arcs), gcc allocates a lot of stack space because of the large switch statement in bpf_jit_insn().

The s390x ALU64_DIV/MOD has been implemented according to the eBPF interpreter specification that used do_div(). This function does a 64-bit by 32-bit divide. It turned out that this was wrong and now the interpreter uses div64_u64_rem() for full 64-bit division. So fix this and use full 64-bit division in the s390x eBPF backend code. Signed-off-by:

bnx2x's 'disable_tpa=1' module option is not respected properly and TPA (transparent packet aggregation) remains enabled. Even though the module option causes LRO to be disabled, TPA is enabled in GRO mode. Additionally, disabling GRO via ethtool then has no effect. One can still observe tpa_* statistics increase and large packets being received in tcpdump. The bug was an unintended consequence of commit aebf6244 "bnx2x: Be more forgiving toward SW GRO". Fix it by following the bp->disable_tpa flag when initializing fp's. Signed-off-by:

Sylvain Rochet says: ==================== ppp: mppe: fixes MPPE desync on links which don't guarantee packet ordering I am currently having an issue with PPP over L2TP (UDP) and MPPE in stateless mode (default mode), UDP does not guarantee packet ordering so we might get out of order packet. MPPE needs to be continuously synched so we should drop late UDP packet. I added a printk on the number of time we rekeyed in MPPE decompressor, this is what we currently have if we receive a slightly out of order UDP packet: [1731001.049206] mppe_decompress[1]: ccount 1559 [1731001.049216] mppe_decompress[1]: rekeyed 1 times [1731001.049228] mppe_decompress[1]: ccount 1560 [1731001.049232] mppe_decompress[1]: rekeyed 1 times [1731001.050170] mppe_decompress[1]: ccount 1562 [1731001.050182] mppe_decompress[1]: rekeyed 2 times [1731001.050191] mppe_decompress[1]: ccount 1561 [1731001.062576] mppe_decompress[1]: rekeyed 4095 times ^^^^ This is obviously wrong, we missed packet 1561 and we already rekeyed 2 times for 1562 we previously received, we can't recover the decryption key we need for 1561, we should drop it instead of rekeying 4095 times.

When PPP is used over a link which does not guarantee packet ordering, we might get late MPPE packets. This is a problem because MPPE must be kept synchronized and the current implementation does not drop them and rekey 4095 times instead of 0, which is wrong. In order to prevent rekeying about a whole count space times (~ 4095 times), drop packets which are not within the forward 4096/2 window and increase sanity error counter. Signed-off-by:

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used. Work around the issue by setting SS to __KERNEL_DS __switch_to, thus ensuring that SYSRET never happens with SS set to NULL. This was exposed by a recent vDSO cleanup.

Pull intel iommu updates from David Woodhouse: "This lays a little of the groundwork for upcoming Shared Virtual Memory support — fixing some bogus #defines for capability bits and adding the new ones, and starting to use the new wider page tables where we can, in anticipation of actually filling in the new fields therein. It also allows graphics devices to be assigned to VM guests again. This got broken in 3.17 by disallowing assignment of RMRR-afflicted devices. Like USB, we do understand why there's an RMRR for graphics devices — and unlike USB, it's actually sane. So we can make an exception for graphics devices, just as we do USB controllers. Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty hack to allow broken BIOSes to forbid us from using X2APIC when they do stupid and invasive things and would break if we did. Someone noticed that since Windows doesn't have full IOMMU support for DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid initialising the IOMMU on the graphics unit altogether. This means that it would be available for use in "driver mode", where the IOMMU registers are made available through a BAR of the graphics device and the graphics driver can do SVM all for itself. So they started setting the X2APIC_OPT_OUT bit on *all* platforms with SVM capabilities. And even the platforms which *might*, if the planets had been aligned correctly, possibly have had SVM capability but which in practice actually don't" * git://git.infradead.org/intel-iommu: iommu/vt-d: support extended root and context entries iommu/vt-d: Add new extended capabilities from v2.3 VT-d specification iommu/vt-d: Allow RMRR on graphics devices too iommu/vt-d: Print x2apic opt out info instead of printing a warning iommu/vt-d: kill bogus ecap_niotlb_iunits()

Pull more power management and ACPI updates from Rafael Wysocki: "These are fixes mostly (intel_pstate, ACPI core, ACPI EC driver, cpupower tool), a new CPU ID for the Intel RAPL driver and one intel_pstate driver improvement that didn't make it to my previous pull requests due to timing. Specifics: - Fix a build warning in the intel_pstate driver showing up in non-SMP builds (Borislav Petkov) - Change one of the intel_pstate's P-state selection parameters for Baytrail and Cherrytrail CPUs to significantly improve performance at the cost of a small increase in energy consumption (Kristen Carlson Accardi) - Fix a NULL pointer dereference in the ACPI EC driver due to an unsafe list walk in the query handler removal routine (Chris Bainbridge) - Get rid of a false-positive lockdep warning in the ACPI container hot-remove code (Rafael J Wysocki) - Prevent the ACPI device enumeration code from creating device objects of a wrong type in some cases (Rafael J Wysocki) - Add Skylake processors support to the Intel RAPL power capping driver (Brian Bian) - Drop the stale MAINTAINERS entry for the ACPI dock driver that is regarded as part of the ACPI core and maintained along with it now (Chao Yu) - Fix cpupower tool breakage caused by a library API change in libpci 3.3.0 (Lucas Stach)" * tag 'pm+acpi-4.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: Add a scan handler for PRP0001 ACPI / scan: Annotate physical_node_lock in acpi_scan_is_offline() ACPI / EC: fix NULL pointer dereference in acpi_ec_remove_query_handler() MAINTAINERS: remove maintainship entry of docking station driver powercap / RAPL: Add support for Intel Skylake processors cpufreq: intel_pstate: Fix an annoying !CONFIG_SMP warning intel_pstate: Change the setpoint for Atom params cpupower: fix breakage from libpci API change
