2010-05-21serial: bfin_sport_uart: Use resource size to fix off-by-one errorTobias Klauser
Use the resource_size function instead of manually calculating the resource size. This actually fixes an off-by-one error. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-05-21serial: timbuart: make sure last byte is sent when port is closedRichard Röjfors
Fix a problem in early versions of the FPGA IP. In certain situations the IP reports that the FIFO is empty, but a byte is still clocked out. If a flush is done at that point the currently clocked byte is canceled. This causes incompatibilities with the upper layers when a port is closed, it waits until the FIFO is empty and then closes the port. During close the FIFO is flushed -> the last byte is not sent properly. Now the FIFO is only flushed if it is reported to be non-empty. Which makes the currently clocked out byte to finish.

2010-05-21serial: uartlite: move from byte accesses to word accessesJohn Linn
Byte accesses for I/O devices in Xilinx IP is going to be less desired in the future such that the driver is being changed to use 32 bit accesses. This change facilitates using the uartlite IP over a PCIe bus which only allows 32 bit accesses.

2010-05-21HID: fix up 'EMBEDDED' mess in KconfigJiri Kosina
The whole point of making some of the drivers automatically selected unless 'EMBEDDED' was to handle quirks transparently after their separation from the generic core. Over time, some of the later-added quirks grew into more standalone drivers, implementing non-trivial features a being larger than a few bytes of code. In addition to that, some of the standalone drivers don't make sense for 99.9% of the users, as they are very specific to rare devices. Therefore build by default in only those drivers which - we historically used to support even before quirk separation from the core code - are isolated enough and likely to hit quite large portion of the users anyway (Microsoft, Logitech) Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2010-05-21net: fix problem in dequeuing from input_pkt_queueTom Herbert
Fix some issues introduced in batch skb dequeuing for input_pkt_queue. The primary issue it that the queue head must be incremented only after a packet has been processed, that is only after __netif_receive_skb has been called. This is needed for the mechanism to prevent OOO packet in RFS. Also when flushing the input_pkt_queue and process_queue, the process queue should be done first to prevent OOO packets. Because the input_pkt_queue has been effectively split into two queues, the calculation of the tail ptr is no longer correct. The correct value would be head+input_pkt_queue->len+process_queue->len. To avoid this calculation we added an explict input_queue_tail in softnet_data. The tail value is simply incremented when queuing to input_pkt_queue.

2010-05-21powerpc: Remove unused 'protect4gb' boot parameterFUJITA Tomonori

In 2008, the IOMMU was fixed to use the boundary_mask parameter per device properly. So 'protect4gb' workaround was removed (the 383af9525bb27f927511874f6306247ec13f1c28).

At the moment only the RAS code uses event-sources interrupts (for EPOW events and internal errors) so request_ras_irqs() (which actually requests the event-sources interrupts) is found in ras.c and is static. We want to be able to use event-sources interrupts in other pseries code, so let's rename request_ras_irqs() to request_event_sources_irqs() and move it to event_sources.c. This will be used in an upcoming patch that adds support for IO Event interrupts that come through as event sources.
