vm: convert mtdchar mmap to vm_iomap_memory() helper

2013-04-26T04:19:56Z

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

2013-04-26T04:19:56Z

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

2013-04-26T04:19:56Z

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).

fbcon: fix locking harder

2013-04-26T04:19:56Z

commit 054430e773c9a1e26f38e30156eff02dedfffc17 upstream. Okay so Alan's patch handled the case where there was no registered fbcon, however the other path entered in set_con2fb_map pit. In there we called fbcon_takeover, but we also took the console lock in a couple of places. So push the console lock out to the callers of set_con2fb_map, this means fbmem and switcheroo needed to take the lock around the fb notifier entry points that lead to this. This should fix the efifb regression seen by Maarten. Tested-by: Maarten Lankhorst Tested-by: Lu Hua Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

ssb: implement spurious tone avoidance

2013-04-26T04:19:55Z

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

2013-04-26T04:19:55Z

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

2013-04-26T04:19:55Z

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.

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

2013-04-26T04:19:54Z

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.

mtd: Disable mtdchar mmap on MMU systems

2013-04-17T04:27:27Z

commit f5cf8f07423b2677cebebcebc863af77223a4972 upstream. This code was broken because it assumed that all MTD devices were map-based. Disable it for now, until it can be fixed properly for the next merge window. Signed-off-by: David Woodhouse Signed-off-by: Greg Kroah-Hartman

r8169: fix auto speed down issue

2013-04-17T04:27:27Z

commit e2409d83434d77874b461b78af6a19cd6e6a1280 upstream. It would cause no link after suspending or shutdowning when the nic changes the speed to 10M and connects to a link partner which forces the speed to 100M. Check the link partner ability to determine which speed to set. Signed-off-by: Hayes Wang Acked-by: Francois Romieu Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman
