Current NFSv4.1/pNFS client assumes that MDS supports only one layout type. While it's true for most existing servers, nevertheless, this can be change in the near future. For now, this patch just plumbs in the ability to track a list of layouts in the fsinfo structure. The existing behavior of the client is preserved, by having it just select the first entry in the list.

Pull ARM fixes from Russell King: "Most of this update are fixes primarily discovered from testing on the older StrongARM 1110 and PXA systems, as a result of recent interest from several people in these platforms: - Locomo interrupt handling incorrectly stores the handler data in the chip's private data slot: when Locomo is combined with an interrupt controller who's chip uses the chip private data, this leads to an oops. - SA1111 was missing a call to clk_disable() to clean up after a failed probe. - SA1111 and PCMCIA suspend/resume was broken: The PCMCIA "ds" layer was using the legacy bus suspend/resume methods, which the core PM code is no longer calling as a result of device_pm_check_callbacks() introduced in commit aa8e54b5 ("PM / sleep: Go direct_complete if driver has no callbacks"). SA1111 was broken due to changes to PCMCIA which makes PCMCIA suspend itself later than the SA1111 code expects, and resume before the SA1111 code has initialised access to the pcmcia sub-device. - the default SA1111 interrupt mask polarity got messed up when it was converted to use a dynamic interrupt base number for its interrupts. - fix platform_get_irq() error code propagation, which was causing problems on platforms where the interrupt may not be available at probe time in DT setups. - fix the lack of clock to PCMCIA code on PXA platforms, which was omitted in conversions of PXA to CCF. - fix an oops in the PXA PCMCIA code caused by a previous commit not realising that Lubbock is different from the rest of the PXA PCMCIA drivers. - ensure that SA1111 low-level PCMCIA drivers propagate their error codes to the main probe function, rather than the driver silently accepting a failure. - fix the sa11xx debugfs reporting of timing information, which always indicated zero due to the clock being a factor of 1000 out. - fix the polarity of the status change signal reported from the sockets.

When handling ack for atomic opcodes like "fetch&add" or "cmp&swp", the method send_atomic_ack() saves the ack before sending it, in case it gets lost and never reach the requester. In which case the method duplicate_request() will need to find it using the duplicated request.psn. But send_atomic_ack() used a wrong psn value and thus the above ack was never found. This fix uses the ack.psn to locate the ack in case its needed. This fix also copies the ack packet to the skb's control buffer since duplicate_request() will need it when calling rxe_xmit_packet() Fixes: 8700e3e7 ("Soft RoCE driver") Signed-off-by: NYonatan Cohen <yonatanc@mellanox.com> Signed-off-by: NLeon Romanovsky <leon@kernel.org> Signed-off-by: NDoug Ledford <dledford@redhat.com>

由 Jack Morgenstein 提交于
When sending QP1 MAD packets which use a GRH, the source GID (which consists of the 64-bit subnet prefix, and the 64 bit port GUID) must be included in the packet GRH. For SR-IOV, a GID cache is used, since the source GID needs to be the slave's source GID, and not the Hypervisor's GID. This cache also included a subnet_prefix. Unfortunately, the subnet_prefix field in the cache was never initialized (to the default subnet prefix 0xfe80::0). As a result, this field remained all zeroes. Therefore, when SR-IOV was active, all QP1 packets which included a GRH had a source GID subnet prefix of all-zeroes. However, the subnet-prefix should initially be 0xfe80::0 (the default subnet prefix). In addition, if OpenSM modifies a port's subnet prefix, the new subnet prefix must be used in the GRH when sending QP1 packets. To fix this we now initialize the subnet prefix in the SR-IOV GID cache to the default subnet prefix. We update the cached value if/when OpenSM modifies the port's subnet prefix. We take this cached value when sending QP1 packets when SR-IOV is active. Note that the value is stored as an atomic64. This eliminates any need for locking when the subnet prefix is being updated. Note also that we depend on the FW generating the "port management change" event for tracking subnet-prefix changes performed by OpenSM. If running early FW (before 2.9.4630), subnet prefix changes will not be tracked (but the default subnet prefix still will be stored in the cache; therefore users who do not modify the subnet prefix will not have a problem). IF there is a need for such tracking also for early FW, we will add that capability in a subsequent patch.

Because of an incorrect bit-masking done on the join state bits, when handling a join request we failed to detect a difference between the group join state and the request join state when joining as send only full member (0x8). This caused the MC join request not to be sent. This issue is relevant only when SRIOV is enabled and SM supports send only full member.

This fix solves a race between light flush and on the fly joins. Light flush doesn't set the device to down and unset IPOIB_OPER_UP flag, this means that if while flushing we have a MC join in progress and the QP was attached to BC MGID we can have a mismatches when re-attaching a QP to the BC MGID. The light flush would set the broadcast group to NULL causing an on the fly join to rejoin and reattach to the BC MCG as well as adding the BC MGID to the multicast list. The flush process would later on remove the BC MGID and detach it from the QP. On the next flush the BC MGID is present in the multicast list but not found when trying to detach it because of the previous double attach and single detach.

Merge tag 'samsung-fixes-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into fixes Pull "ARM: exynos: Fixes for v4.8, secound round" from Krzysztof Kozłowski: 1. A recent change in populating irqchip devices from Device Tree broke Suspend to RAM on Exynos boards due to lack of probing of PMU (Power Management Unit) driver. Multiple drivers attach to the PMU's DT node: irqchip, clock controller and PMU platform driver for handling suspend. The new irqchip code marked the PMU's DT node as OF_POPULATED but we need to attach to this node also PMU platform driver. 2. Add Javier as additional reviewer for Exynos patches. * tag 'samsung-fixes-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: ARM: EXYNOS: Clear OF_POPULATED flag from PMU node in IRQ init callback MAINTAINERS: Add myself as reviewer for Samsung Exynos support

Some full-speed mceusb infrared transceivers contain invalid endpoint descriptors for their interrupt endpoints, with bInterval set to 0. In the past they have worked out okay with the mceusb driver, because the driver sets the bInterval field in the descriptor to 1, overwriting whatever value may have been there before. However, this approach was never sanctioned by the USB core, and in fact it does not work with xHCI controllers, because they use the bInterval value that was present when the configuration was installed. Currently usbcore uses 32 ms as the default interval if the value in the endpoint descriptor is invalid. It turns out that these IR transceivers don't work properly unless the interval is set to 10 ms or below. To work around this mceusb problem, this patch changes the endpoint-descriptor parsing routine, making the default interval value be 10 ms rather than 32 ms.

We have CONFIG_BLACKFIN ifdef redefining all musb registers in musb_regs.h and tusb6010.h is never included causing a build error with blackfin-allmodconfig and COMPILE_TEST. Let's fix the issue by not building tusb6010 if CONFIG_BLACKFIN is selected.

While the Intel PMU monitors the LLC when perf enables the HW_CACHE_REFERENCES and HW_CACHE_MISSES events, these events monitor L1 instruction cache fetches (0x0080) and instruction cache misses (0x0081) on the AMD PMU. This is extremely confusing when monitoring the same workload across Intel and AMD machines, since parameters like, $ perf stat -e cache-references,cache-misses measure completely different things. Instead, make the AMD PMU measure instruction/data cache and TLB fill requests to the L2 and instruction/data cache and TLB misses in the L2 when HW_CACHE_REFERENCES and HW_CACHE_MISSES are enabled, respectively. That way the events measure unified caches on both platforms.
