So we've had a fair few reports of fbcon handover breakage between efi/vesafb and i915 surface recently, so I dedicated a couple of days to finding the problem. Essentially the last thing we saw was the conflicting framebuffer message and that was all. So after much tracing with direct netconsole writes (printks under console_lock not so useful), I think I found the race. Thread A (driver load) Thread B (timer thread) unbind_con_driver -> | bind_con_driver -> | vc->vc_sw->con_deinit -> | fbcon_deinit -> | console_lock() | | | | fbcon_flashcursor timer fires | console_lock() <- blocked for A | | fbcon_del_cursor_timer -> del_timer_sync (BOOM) Of course because all of this is under the console lock, we never see anything, also since we also just unbound the active console guess what we never see anything. Hopefully this fixes the problem for anyone seeing vesafb->kms driver handoff. v1.1: add comment suggestion from Alan. Cc: stable@vger.kernel.org Signed-off-by: NDave Airlie <airlied@redhat.com>

Correct the offset by subtracting 20 from tm_hour before taking the modulo 12. [ "Why 20?" I hear you ask. Or at least I did. Here's the reason why: RS5C348_BIT_PM is 32, and is - stupidly - included in the RS5C348_HOURS_MASK define. So it's really subtracting out that bit to get "hour+12". But then because it does things modulo 12, it needs to add the 12 in again afterwards anyway. This code is confused. It would be much clearer if RS5C348_HOURS_MASK just didn't include the RS5C348_BIT_PM bit at all, then it wouldn't need to do the silly subtract either. Whatever. It's all just math, the end result is the same. - Linus ] Reported-by: NJames Nute <newten82@gmail.com> Tested-by: NJames Nute <newten82@gmail.com> Signed-off-by: NAtsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: <stable@vger.kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Worst cases on machines with multiple 10 GigE cards and multiple IB cards have depleted the entire first socket of IRQs.

If you do a page flip with no flags set then event is NULL. If event is NULL then the vmw_gfx driver likes to go digging into NULL and extracts NULL->base.file_priv.

Here TRANSPORT_IQN_LEN is 224, which is a multiple of 4. Since vhost_tpgt is 2 bytes and abi_version is 4, the total size would be 230. But gcc needs struct size be aligned to first field size, which is 4 bytes, so it pads the structure by extra 2 bytes to the total of 232. This padding is very undesirable in an ABI: - it can not be initialized easily - it can not be checked easily - it can leak information between kernel and userspace Simplest solution is probably just to make the padding explicit.

James Bottomley reported [1] a massive power regression, due to the enabling of semaphores by default in 3.5. A workaround for him is to again disable semaphores. And indeed, his system has a very hard time to enter rc6 with semaphores enabled. Ben Widawsky run around with a kill-a-watt a lot and noticed: - There are indeed a few rare systems that seem to have a hard time entering rc6 when desktop-idle. - One machine, The Indestructible Toshiba regressed in this behaviour between 3.5 and 3.6 in a merge commit! So rc6 behaviour with the current setting seems to be highly timing dependent and not robust at all. - The behaviour James reported wrt semaphores seems to be a freak timing thing that only happens on his specific machine, confirming that enabling semaphores shouldn't reduce rc6 residency. Now furthermore the Google ChromeOS guys reported [2] a while ago that at least on some machines a simply a blinking cursor can keep the gpu turbo at the highest frequency. This is because the current rps limits used on snb/ivb are highly asymmetric. On the theory that gpu turbo and rc6 tuning values are related, we've tried whether the much saner looking (since much less asymmetric) rps tuning values used for hsw would also help entering rc6 more robustly. And it seems to mostly work, and we don't really have the resources to through-roughly tune things in any better way: The values from the ChromeOS ppl seem to fare a bit worse for James' machine, so I guess we better stick with something vpg (the gpu hw/windows group) provided, hoping that they've done their jobs.

The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special keys working, adds possibility to control fan like Windows does, controls Touchpad Disabled LED, toggles touchpad state via keyboard controller and corrects touchpad behavior on resume from suspend. It is new, modified version of patch. Now it does not depend on psmouse and does not need patching of input subsystem.
