2007-05-15alpha: fix hard_smp_processor_id compile errorSimon Horman
"Remove hardcoding of hard_smp_processor_id on UP systems", 2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f in Linus' tree, moved the definition of hard_smp_processor_id linux/smp.h to asm/smp.h for UP systems. This causes a regression on Alpha. cc1: warnings being treated as errors arch/alpha/kernel/setup.c: In function 'setup_arch': arch/alpha/kernel/setup.c:506: warning: implicit declaration of function 'hard_smp_processor_id' make[1]: *** [arch/alpha/kernel/setup.o] error 1 make: *** [arch/alpha/kernel] error 2 By including asm/smp.h non-conditionally in asm/mmu_context.h the problem appears to be resolved.

2007-05-15nommu: add ioremap_page_range()Paul Mundt
lib/ioremap.c is presently only built in if CONFIG_MMU is set. While this is reasonable, platforms that support both CONFIG_MMU=y or n need to be able to call in to this regardless. As none of the current nommu platforms do anything special with ioremap(), we assume that it's always successful. This fixes the SH-4 build with CONFIG_MMU=n.

2007-05-15epoll locks changes and cleanupsDavide Libenzi
Changes the rwlock to a spinlock, and drops the use-count variable. Operations are always bound by the mutex now, so the use-count is no more needed. For the same reason, the rwlock can become a simple spinlock.

2007-05-15fix epoll single pass code and add wait-exclusive flagDavide Libenzi
Fixes the epoll single pass code. During the unlocked event delivery (to userspace) code, the poll callback can re-issue new events, and we must receive them correctly. Since we loop in a lockless fashion, we want to be O(nready), and we don't want to flash on/off the spinlock for every event, we have the poll callback to use a secondary list to queue events while we're inside the event delivery loop. The rw_semaphore has been turned into a mutex. This patch also adds the wait-exclusive flag, as suggested by Davi Arnaut.

2007-05-14Revert "ipmi: add new IPMI nmi watchdog handling"Linus Torvalds
This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not. Manually fix up conflicts in arch/x86_64/kernel/traps.c and drivers/char/ipmi/ipmi_watchdog.c.

2007-05-14IPoIB/cm: Optimize stale connection detectionMichael S. Tsirkin
In the presence of some running RX connections, we repeat queue_delayed_work calls each 4 RX WRs, which is a waste. It's enough to start stale task when a first passive connection is added, and rerun it every IPOIB_CM_RX_DELAY as long as there are outstanding passive connections. This removes some code from RX data path. Signed-off-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-05-14IB/mthca: Set cleaned CQEs back to HW ownership when cleaning CQMichael S. Tsirkin
mthca_cq_clean() updates the CQ consumer index without moving CQEs back to HW ownership. As a result, the same WRID might get reported twice, resulting in a use-after-free. This was observed in IPoIB CM. Fix by moving all freed CQEs to HW ownership. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=617> Signed-off-by: Michael S.

2007-05-14RDMA/cma: Add check to validate that cm_id is bound to a deviceSean Hefty
Several checks in the rdma_cm check against the state of the cm_id, but only to validate that the cm_id is bound to an underlying transport specific CM and an RDMA device. Make the check explicit in what we're trying to check for, since we're not synchronizing against the cm_id state. This will allow a user to disconnect a cm_id or reject a connection after receiving a device removal event.

2007-05-14RDMA/cma: Fix synchronization with device removal in cma_iw_handlerSean Hefty
The cma_iw_handler needs to validate the state of the rdma_cm_id before processing a new connection request to ensure that a device removal is not already being processed for the same rdma_cm_id. Without the state check, the user can receive simultaneous callbacks for the same cm_id, or a callback after they've destroyed the cm_id.

2007-05-14IB/ehca: Correctly set GRH mask bit in ehca_modify_qp()Joachim Fenkes
The driver needs to always supply the "GRH present" flag to the hypervisor, whether it's true or false. Not supplying it (i.e. not setting the corresponding mask bit) amounts to a "perhaps", which we don't want.

2007-05-14IB/ipath: Shadow the gpio_mask registerArthur Jones
Once upon a time, GPIO interrupts were rare. But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.

uar_lock spinlock was used in mlx4_ib_cq_arm without being initialized (this only affects 32-bit archs, because uar_lock is not used on 64-bit archs and MLX4_INIT_DOORBELL_LOCK() is a NOP). Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-05-14[IPSEC]: Check validity of direction in xfrm_policy_byidHerbert Xu
The function xfrm_policy_byid takes a dir argument but finds the policy using the index instead. We only use the dir argument to update the policy count for that direction. Since the user can supply any value for dir, this can corrupt our policy count. I know this is the problem because a few days ago I was deleting policies by hand using indicies and accidentally typed in the wrong direction. It still deleted the policy and at the time I thought that was cool. In retrospect it isn't such a good idea :) I decided against letting it delete the policy anyway just in case we ever remove the connection between indicies and direction.
