* x86, nmi, drivers: Fix nmi splitup build bugIngo Molnar2011-10-101-0/+1

* x86, nmi: Wire up NMI handlers to new routinesDon Zickus2011-10-103-54/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just convert all the files that have an nmi handler to the new routines. Most of it is straight forward conversion. A couple of places needed some tweaking like kgdb which separates the debug notifier from the nmi handler and mce removes a call to notify_die. [Thanks to Ying for finding out the history behind that mce call https://lkml.org/lkml/2010/5/27/114 And Boris responding that he would like to remove that call because of it https://lkml.org/lkml/2011/9/21/163] The things that get converted are the registeration/unregistration routines and the nmi handler itself has its args changed along with code removal to check which list it is on (most are on one NMI list except for kgdb which has both an NMI routine and an NMI Unknown routine).

| * net: xen-netback: correctly restart Tx after a VM restore/migrateDavid Vrabel2011-10-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a VM is saved and restored (or migrated) the netback driver will no longer process any Tx packets from the frontend. xenvif_up() does not schedule the processing of any pending Tx requests from the front end because the carrier is off. Without this initial kick the frontend just adds Tx requests to the ring without raising an event (until the ring is full). This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net: xen-netback: convert to hw_features) which reordered the calls to xenvif_up() and netif_carrier_on() in xenvif_connect().

| * bonding: properly stop queuing work when requestedAndy Gospodarek2011-10-033-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a test where a pair of bonding interfaces using ARP monitoring were both brought up and torn down (with an rmmod) repeatedly, a panic in the timer code was noticed. I tracked this down and determined that any of the bonding functions that ran as workqueue handlers and requeued more work might not properly exit when the module was removed. There was a flag protected by the bond lock called kill_timers that is set when the interface goes down or the module is removed, but many of the functions that monitor link status now unlock the bond lock to take rtnl first. There is a chance that another CPU running the rmmod could get the lock and set kill_timers after the first check has passed. This patch does not allow any function to queue work that will make itself run unless kill_timers is not set. I also noticed while doing this work that bond_resend_igmp_join_requests did not have a check for kill_timers, so I added the needed call there as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most asics just use the hw default value which requires no explicit programming. For those that need a different value, the vbios will program it properly. As such, there's no need to program these registers explicitly in the driver.

Due to the number of issues recently discovered on some x86 chipsets, make this the default behavior. Also, add the option for peer to peer DMA MPS configuration. Peer to peer DMA is outside the scope of this patch, but MPS configuration could prevent it from working by having the MPS on one root port different than the MPS on another. To work around this, simply make the system wide MPS the smallest possible value (128B).

As my SDVO DVI supports hotplug detect interrupts, the fix is to enable them, and hook them in to the various bits of driver infrastructure so that they work reliably. Note that this is only tested on single-function DVI-D SDVOs, on two platforms (965GME and 945GSE), and has not been checked against a specification document. With lots of help from Adam Jackson <ajax@redhat.com> on IRC.

The previous code was incorrectly clamping the frame buffer bpc to the display bpc, effectively disabling dithering all of the time as the computed frame buffer bpc would never be larger than the display bpc.
