* cxgb3: map entire Rx page, feed map+offset to Rx ring.Divy Le Ray2009-03-27
| | | | | | | | | | | DMA mapping can be expensive in the presence of iommus. Reduce the Rx iommu activity by mapping an entire page, and provide the H/W the mapped address + offset of the current page chunk. Reserve bits at the end of the page to track mapping references, so the page can be unmapped. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.Thierry Reding2009-03-27
| | | | | | | | | | | | | | This patch adds a platform device driver that supports the OpenCores 10/100 Mbps Ethernet MAC. The driver expects three resources: one IORESOURCE_MEM resource defines the memory region for the core's memory-mapped registers while a second IORESOURCE_MEM resource defines the network packet buffer space. The third resource, of type IORESOURCE_IRQ, associates an interrupt with the driver.

|\ \ | | | | | | | | | | | | | | | | | | | | | * 'bkl-removal' of git://git.lwn.net/linux-2.6: Rationalize fasync return values Move FASYNC bit handling to f_op->fasync() Use f_lock to protect f_flags Rename struct file->f_ep_lock
| * | Rationalize fasync return valuesJonathan Corbet2009-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

| * | Use f_lock to protect f_flagsJonathan Corbet2009-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, changes to struct file->f_flags have been done under BKL protection, or with no protection at all. This patch causes all f_flags changes after file open/creation time to be done under protection of f_lock. This allows the removal of some BKL usage and fixes a number of longstanding (if microscopic) races.
