2015-10-29staging: wilc1000: wilc_handle_isr: add argument wilc to wilc_handle_isrGlen Lee
This patch add new argument wilc to wilc_handle_isr and pass wilc to the function. It is void type for now because wilc_wlan.c was implemented platform independently at the beginning (linux_wlan.c is implementation of LINUX part), so the header file which defines struct wilc cannot be included at this moment, but this driver is dedicated to LINUX so wilc_wlan.c and linux_wlan.c will be merged. After that, this void type will be changed with struct wilc as well as other functions which are using void type in wilc_wlan.h.

When under heavy load, the receive interrupt handler can run too long with IRQs disabled. Add a mixed-mode threading scheme. Initially process packets in the handler for quick responses (latency).

In preparation for threading the receive interrupt, add irqsaves in the packet processing path. When the receive interrupt is threaded, the packet processing path is no longer guaranteed to have IRQs disabled. Add irqsaves where needed on several locks in the packet processing path. Anything that did not have an obvious, "close" irqsave in its caller is a candidate.

2015-10-27staging/rdma/hfi1: Allow tuning of SDMA interrupt rateMitko Haralanov
The SDMA engines were configured to generate progress interrupts every time they processed N/2 descriptors (where N is the size of the descriptor queue). This interval was too infrequent, leading to degraded performance. This commit adds a module parameter, as well as a recommended default, which allows for the tuning of the interrupt frequency.

2015-10-27staging/rdma/hfi1: Wrong cast breaks desired pointer arithmeticMitko Haralanov
The address being mapped into a process's memory for notification events was improperly calculated due to cast that was happening too early. dd->events is a pointer and should have been casted to unsigned long after the pointer arithmetic was done, not before. As a result, processes were looking at the wrong place and not seeing their notification events.

2015-10-27staging/rdma/hfi1: Prevent silent data corruption with user SDMAMitko Haralanov
User SDMA keeps track of progress into the submitted IO vectors by tracking an offset into the vectors when packets are submitted. This offset is updated after a successful submission of a txreq to the SDMA engine. The same offset was used when determining whether an IO vector should be 'freed' (pages unpinned) in the SDMA callback functions. This was causing a silent data corruption in big jobs (> 2 nodes, 120 ranks each) on the receive side because the send side was mistakenly unpinning the vector pages before the HW has processed all descriptors referencing the vector.
