2008-05-19svcrdma: Remove unused READ_DONE context flags bitTom Tucker3-3/+0
The RDMACTXT_F_READ_DONE bit is not longer used. Remove it. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Return error from rdma_read_xdr so caller knows to free contextTom Tucker1-7/+16
The rdma_read_xdr function did not discriminate between no read-list and an error posting the read-list. This results in a leak of a page if there is an error posting the read-list. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Fix error handling during listening endpoint creationTom Tucker1-11/+13
A listening endpoint isn't known to the generic transport switch until the svc_create_xprt function returns without error. Calling svc_xprt_put within the xpo_create function causes the module reference count to be erroneously decremented. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Free context on post_recv error in send_replyTom Tucker1-1/+2
If an error is encountered trying to post a recv buffer in send_reply, free the passed in context. Return an error to the caller so it is aware that the request was not posted. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Free context on ib_post_recv errorTom Tucker1-0/+2
If there is an error posting the recv WR to the RQ, free the context associated with the WR. This would leak a context when asynchronous errors occurred on the transport while conccurent threads were processing their RPC. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Add put of connection ESTABLISHED reference in rdma_cma_handlerTom Tucker1-0/+1
The svcrdma transport takes a reference when it gets the ESTABLISHED event from the provider. This reference is supposed to be removed when the DISCONNECT event is received, however, the call to svc_xprt_put was missing in the switch statement. This results in the memory associated with the transport never being freed. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Fix return value in svc_rdma_sendTom Tucker1-1/+1
Fix the return value on close to -ENOTCONN so caller knows to free context. Also if a thread is waiting for free SQ space, check for close when waking to avoid posting WR to a closing transport. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Fix race with dto_tasklet in svc_rdma_sendTom Tucker1-18/+22
The svc_rdma_send function will attempt to reap SQ WR to make room for a new request if it finds the SQ full. This function races with the dto_tasklet that also reaps SQ WR. To avoid polling and arming the CQ unnecessarily move the test_and_clear_bit of the RDMAXPRT_SQ_PENDING flag and arming of the CQ to the sq_cq_reap function. Refactor the rq_cq_reap function to match sq_cq_reap so that the code is easier to follow. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svcrdma: Simplify receive buffer postingTom Tucker3-35/+11
The svcrdma transport provider currently allocates receive buffers to the RQ through the xpo_release_rqst method. This approach is overly complicated since it means that the rqstp rq_xprt_ctxt has to be selectively set based on whether the RPC is going to be processed immediately or deferred. Instead, just post the receive buffer when we are certain that we are replying in the send_reply function. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svc: Remove unused header files from svc_xprt.cTom Tucker1-21/+0
This cosmetic patch removes unused header files that svc_xprt.c inherited from svcsock.c Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
2008-05-19svc: Remove extra check for XPT_DEAD bit in svc_xprt_enqueueTom Tucker1-2/+0
Remove a redundant check for the XPT_DEAD bit in the svc_xprt_enqueue function. This same bit is checked below while holding the pool lock and prints a debug message if found to be dead. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>

2008-05-19m68k: Prefix ISA type with ISA_TYPE_Geert Uytterhoeven2-25/+25

2008-05-18i2c/max6875: Really prevent 24RF08 corruptionJean Delvare1-3/+0
i2c-core takes care of the possible corruption of 24RF08 chips for quite some times, so device devices no longer need to do it. And they really should not, as applying the prevention twice voids it. I thought that I had fixed all drivers long ago but apparently I had missed that one. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Ben Gardner <bgardner@wabtec.com>

2008-05-18i2c: Convert remaining new-style drivers to use module aliasingJean Delvare16-39/+143
Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-05-18i2c-nforce2: Disable the second SMBus channel on the DFI Lanparty NF4 ExpertJean Delvare1-4/+24
There is a strange chip at 0x2e on the second SMBus channel of the DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the system. As there's nothing interesting on this SMBus channel, the easiest and safest thing to do is to disable it on that board.

2008-05-18[ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisationLennert Buytenhek2-2/+2
Whereas most Orion 5x machine support code would initialise the PCI subsystem with nr_controllers in their struct hw_pci set to 2, the DNS323 and Kurobox Pro machine support code had nr_controllers set to 1. This was presumably done because on those two machines, the PCI(-X) controller (nr == 1) isn't used, requiring initialisation of only the PCIe controller (nr == 0.) However, not initialising the PCI(-X) controller on boards that don't use it leads to a situation where both the PCIe and the PCI(-X) controller think that their root bus is zero, and it messes up IRQ assignment. This patch changes the DNS323 and Kurobox Pro support code to always use nr_controllers == 2.

The CPU's dma_flush_range() operation needs to clean+invalidate the given memory area if the cache is in writeback mode, or do just the invalidate part if the cache is in writethrough mode, but the current proc-arm{925,926,940,946} (incorrectly) do a cache clean in the latter case.
