* IB/ipath: Implement new verbs DMA mapping functionsRalph Campbell2006-12-126-7/+201
| | | | | | | | | This patch implements the interposing DMA mapping functions to allow support for IOMMUs and remove the dependence on phys_to_virt() and bus_to_virt(). Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB: Add DMA mapping functions to allow device drivers to interposeRalph Campbell2006-12-121-0/+253
| | | | | | | | | | | The QLogic InfiniPath HCAs use programmed I/O instead of HW DMA. This patch allows a verbs device driver to interpose on DMA mapping function calls in order to avoid relying on bus_to_virt() and phys_to_virt() to undo the mappings created by dma_map_single(), dma_map_sg(), etc. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* RDMA/cma: Allow early transition to RTS to handle lost CM messagesSean Hefty2006-12-123-24/+63
| | | | | | | | | | | | | | During connection establishment, the passive side of a connection can receive messages from the active side before the connection event has been delivered to the user. Allow the passive side to send messages in response to received data before the event is delivered. To handle the case where the connection messages are lost, a new rdma_notify() function is added that users may invoke to force a connection into the established state.

* RDMA/cma: Remove unneeded qp_type parameter from rdma_cmSean Hefty2006-12-122-6/+1Star

* IB/ipath: Fix IRQ for PCI Express HCAsRoland Dreier2006-12-121-1/+1
| | | | | | | | | | | Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number. Fix this by using the value of pdev->irq after pci_enable_msi(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/fmr: ib_flush_fmr_pool() may wait too longRoland Dreier2006-12-121-10/+2Star
| | | | | | | | | | | | | | | | | | | ib_flush_fmr_pool() stashes away the request generation number properly, but then goes ahead and rereads it every time it tests whether the flush generation number has caught up. This means that there is a theoretical possibility of livelock, if the request generation number keeps getting bumped and the flush generation number never catches up. The fix is simple: use the request generation number read at the beginning of the function. Also, atomic_inc() followed by atomic_read() can be replaced with atomic_int_return(). There's no real requirement for atomicity here but we might as well shrink the code. This bug was discovered using David Binderman's list of "set but never used" warnings from icc.

* [PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystemNicolas Pitre2006-12-126-8/+13
| | | | | | | | | | | | Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 introduced a dependency that was never meant to exist when the ac97_bus.c module was created. Move ac97_bus.c up the directory hierarchy to make sure it is built when selected even if sound is configured out so things work as originally intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the OCFS2 handshake to ensure essential timeouts are configured identically on all nodes. Only allow changes when there are no connected peers Improves the logic in o2net_advance_rx() which broke now that sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg) Included is the field for userspace-heartbeat timeout to avoid the need for further protocol changes. Uses a global spinlock to ensure the decisions to update configfs entries are made on the correct value. The region covered by the spinlock when incrementing the counter is much larger as this is the more critical case.

| * | i2c: fix broken ds1337 initializationDirk Eibach2006-12-101-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a custom board with ds1337 RTC I found that upgrade from 2.6.15 to 2.6.18 broke RTC support. The main problem are changes to ds1337_init_client(). When a ds1337 recognizes a problem (e.g. power or clock failure) bit 7 in status register is set. This has to be reset by writing 0 to status register. But since there are only 16 byte written to the chip and the first byte is interpreted as an address, the status register (which is the 16th) is never written. The other problem is, that initializing all registers to zero is not valid for day, date and month register. Funny enough this is checked by ds1337_detect(), which depends on this values not being zero. So then treated by ds1337_init_client() the ds1337 is not detected anymore, whereas the failure bit in the status register is still set.
