2009-10-07RDMA/iwcm: Don't call provider reject func with irqs disabledSteve Wise
In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id is destroyed") a call to the provider's reject handler was added to destroy_cm_id() to fix a provider endpoint leak. This call needs to be done with interrupts enabled. So unlock and relock around this call. This is safe because: 1) the provider will do nothing with this endpoint until the iwcm either accepts or rejects. 2) the lock is only released after the iwcm state is changed, so an errant iwcm app that is destroying -and- rejecting the connection concurrently will get a failure on one of the calls.

2009-10-07b43: do not stack-allocate pio rx/tx header and tail buffersAlbert Herranz
The DMA-API debugging facility complains about b43 mapping memory from stack for SDIO-based cards. Indeed, b43 currently allocates the PIO RX/TX header and tail buffers from stack. The solution here is to use heap-allocated buffers instead. Signed-off-by: Albert Herranz <albert_herranz@yahoo.es> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-10-07iwlwifi: incorrect method used for finding valid OTP blocksJay Sternberg
The address stored in the next link address is a word address but when reading the OTP blocks, a byte address is used. Also if the blocks are full and the last link pointer is not zero, then none of the blocks are valid so return an error. The algorithm is simply valid blocks have a next address and that address's contents is zero. Using the wrong address for the next link address gets arbitrary data, obviously. In cases seen, the first block is considered valid when it is not. If the block has in fact been invalidated there may be old data or there may be no data, bad data, or partial data, there is no way of telling. Without this patch it is possible that a device with valid OTP data is unable to work.

2009-10-07PCI: Prevent AER driver from being loaded on non-root port PCIE devicesKenji Kaneshige
A bug was seen on boards using a PLX 8518 switch device which advertises AER on each of it's transparent bridges. The AER driver was loaded for each bridge and this driver tried to access the AER source ID register whenever an interrupt occured on the shared PCI INTX lines. The source ID register does not exist on non root port PCIE device's which advertise AER and trying to access this register causes a unsupported request error on the bridge. Thus, when the next interrupt occurs, another error is found and the non existent source ID register is accessed again, and so it goes on. The result is a spammed dmesg with unsupported request PCI express errors on the bridge device that the AER driver is loaded against.
