vm: convert mtdchar mmap to vm_iomap_memory() helper

2013-04-25T19:51:24Z

commit 8558e4a26b00225efeb085725bc319f91201b239 upstream. This is my example conversion of a few existing mmap users. The mtdchar case is actually disabled right now (and stays disabled), but I did it because it showed up on my "git grep", and I was familiar with the code due to fixing an overflow problem in the code in commit 9c603e53d380 ("mtdchar: fix offset overflow detection").

vm: convert HPET mmap to vm_iomap_memory() helper

2013-04-25T19:51:24Z

commit 2323036dfec8ce3ce6e1c86a49a31b039f3300d1 upstream. This is my example conversion of a few existing mmap users. The HPET case is simple, widely available, and easy to test (Clemens Ladisch sent a trivial test-program for it).

vm: convert fb_mmap to vm_iomap_memory() helper

2013-04-25T19:51:24Z

commit fc9bbca8f650e5f738af8806317c0a041a48ae4a upstream. This is my example conversion of a few existing mmap users. The fb_mmap() case is a good example because it is a bit more complicated than some: fb_mmap() mmaps one of two different memory areas depending on the page offset of the mmap (but happily there is never any mixing of the two, so the helper function still works).

ssb: implement spurious tone avoidance

2013-04-25T19:51:23Z

commit 46fc4c909339f5a84d1679045297d9d2fb596987 upstream. And make use of it in b43. This fixes a regression introduced with 49d55cef5b1925a5c1efb6aaddaa40fc7c693335 b43: N-PHY: implement spurious tone avoidance This commit made BCM4322 use only MCS 0 on channel 13, which of course resulted in performance drop (down to 0.7Mb/s).

ath9k_hw: change AR9580 initvals to fix a stability issue

2013-04-25T19:51:22Z

commit f09a878511997c25a76bf111a32f6b8345a701a5 upstream. The hardware parsing of Control Wrapper Frames needs to be disabled, as it has been causing spurious decryption error reports. The initvals for other chips have been updated to disable it, but AR9580 was left out for some reason. Signed-off-by: Felix Fietkau Signed-off-by: John W. Linville Signed-off-by: Greg Kroah-Hartman

ath9k_htc: accept 1.x firmware newer than 1.3

2013-04-25T19:51:22Z

commit 319e7bd96aca64a478f3aad40711c928405b8b77 upstream. Since the firmware has been open sourced, the minor version has been bumped to 1.4 and the API/ABI will stay compatible across further 1.x releases.

tg3: Add 57766 device support.

2013-04-25T19:51:11Z

commit d3f677afb8076d09d090ff0a5d1229c9dd9f136e upstream. The patch also adds a couple of fixes - For the 57766 and non Ax versions of 57765, bootcode needs to setup the PCIE Fast Training Sequence (FTS) value to prevent transmit hangs. Unfortunately, it does not have enough room in the selfboot case (i.e. devices with no NVRAM). The driver needs to implement this. - For performance reasons, the 2k DMA engine mode on the 57766 should be enabled and dma size limited to 2k for standard sized packets.

md: raid1,10: Handle REQ_WRITE_SAME flag in write bios

2013-04-25T19:51:10Z

commit c8dc9c654794a765ca61baed07f84ed8aaa7ca8c upstream. Set mddev queue's max_write_same_sectors to its chunk_sector value (before disk_stack_limits merges the underlying disk limits.) With that in place, be sure to handle writes coming down from the block layer that have the REQ_WRITE_SAME flag set. That flag needs to be copied into any newly cloned write bio.

can: sja1000: fix handling on dt properties on little endian systems

2013-04-25T19:51:09Z

commit 0443de5fbf224abf41f688d8487b0c307dc5a4b4 upstream. To get correct endianes on little endian cpus (like arm) while reading device tree properties, this patch replaces of_get_property() with of_property_read_u32(). While there use of_property_read_bool() for the handling of the boolean "nxp,no-comparator-bypass" property.

can: mcp251x: add missing IRQF_ONESHOT to request_threaded_irq

2013-04-25T19:51:09Z

commit db388d6460ffa53b3b38429da6f70a913f89b048 upstream. Since commit: 1c6c695 genirq: Reject bogus threaded irq requests threaded irqs must provide a primary handler or set the IRQF_ONESHOT flag. Since the mcp251x driver doesn't make use of a primary handler set the IRQF_ONESHOT flag.
