2011-10-10x86: Fix insn decoder for longer instructionMasami Hiramatsu
Fix x86 insn decoder for hardening against invalid length instructions. This adds length checkings for each byte-read site and if it exceeds MAX_INSN_SIZE, returns immediately. This can happen when decoding user-space binary. Caller can check whether it happened by checking insn.*.got member is set or not.

2011-10-10x86, nmi: Add in logic to handle multiple events and unknown NMIsDon Zickus
Previous patches allow the NMI subsystem to process multipe NMI events in one NMI. As previously discussed this can cause issues when an event triggered another NMI but is processed in the current NMI. This causes the next NMI to go unprocessed and become an 'unknown' NMI. To handle this, we first have to flag whether or not the NMI handler handled more than one event or not. If it did, then there exists a chance that the next NMI might be already processed. Once the NMI is flagged as a candidate to be swallowed, we next look for a back-to-back NMI condition. This is determined by looking at the %rip from pt_regs. If it is the same as the previous NMI, it is assumed the cpu did not have a chance to jump back into a non-NMI context and execute code and instead handled another NMI. If both of those conditions are true then we will swallow any unknown NMI. There still exists a chance that we accidentally swallow a real unknown NMI, but for now things seem better. An optimization has also been added to the nmi notifier rountine. Because x86 can latch up to one NMI while currently processing an NMI, we don't have to worry about executing _all_ the handlers in a standalone NMI. The idea is if multiple NMIs come in, the second NMI will represent them. For those back-to-back NMI cases, we have the potentail to drop NMIs. Therefore only execute all the handlers in the second half of a detected back-to-back NMI.

2011-10-10x86, nmi: Wire up NMI handlers to new routinesDon Zickus
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).

2011-10-10x86, nmi: Create new NMI handler routinesDon Zickus
The NMI handlers used to rely on the notifier infrastructure. This worked great until we wanted to support handling multiple events better. One of the key ideas to the nmi handling is to process _all_ the handlers for each NMI. The reason behind this switch is because NMIs are edge triggered. If enough NMIs are triggered, then they could be lost because the cpu can only latch at most one NMI (besides the one currently being processed). In order to deal with this we have decided to process all the NMI handlers for each NMI. This allows the handlers to determine if they recieved an event or not (the ones that can not determine this will be left to fend for themselves on the unknown NMI list). As a result of this change it is now possible to have an extra NMI that was destined to be received for an already processed event. Because the event was processed in the previous NMI, this NMI gets dropped and becomes an 'unknown' NMI. This of course will cause printks that scare people. However, we prefer to have extra NMIs as opposed to losing NMIs and as such are have developed a basic mechanism to catch most of them. That will be a later patch. To accomplish this idea, I unhooked the nmi handlers from the notifier routines and created a new mechanism loosely based on doIRQ. The reason for this is the notifier routines have a couple of shortcomings. One we could't guarantee all future NMI handlers used NOTIFY_OK instead of NOTIFY_STOP. Second, we couldn't keep track of the number of events being handled in each routine (most only handle one, perf can handle more than one). Third, I wanted to eventually display which nmi handlers are registered in the system in /proc/interrupts to help see who is generating NMIs. The patch below just implements the new infrastructure but doesn't wire it up yet (that is the next patch). Its design is based on doIRQ structs and the atomic notifier routines. So the rcu stuff in the patch isn't entirely untested (as the notifier routines have soaked it) but it should be double checked in case I copied the code wrong.

2011-10-10perf, intel: Use GO/HO bits in perf-ctrGleb Natapov
Intel does not have guest/host-only bit in perf counters like AMD does. To support GO/HO bits KVM needs to switch EVENTSELn values (or PERF_GLOBAL_CTRL if available) at a guest entry. If a counter is configured to count only in a guest mode it stays disabled in a host, but VMX is configured to switch it to enabled value during guest entry. This patch adds GO/HO tracking to Intel perf code and provides interface for KVM to get a list of MSRs that need to be switched on a guest entry. Only cpus with architectural PMU (v1 or later) are supported with this patch. To my knowledge there is not p6 models with VMX but without architectural PMU and p4 with VMX are rare and the interface is general enough to support them if need arise.

A couple of changes to the Tegra maintainership setup: I'm very glad to bring on Stephen Warren on board as a maintainer. The work he has done so far is excellent, and the fact that he works for Nvidia means he has long-term interest in the platform. Erik Gilling did an astounding amount of work on getting things up and running but has been a silent partner on the maintainership side for a while, and is stepping down. Thanks for your contributions so far, Erik. Finally, update the git URL since I'll take over running the main repo for a while. Overall maintainership model isn't changing much at this time: We'll all three review patches as appropriate, and one of us will collect the main repo (me at this time).

2011-10-08pata_sis: enable MWDMA for UDMA 133 chipsetDan McGee
This ports the timing values over from the old IDE driver into the new PATA-based one. The comment was lying when it stated the old driver was not MWDMA capable. Boot tested on actual hardware using 'libata.force=mwdma2'. Signed-off-by: Dan McGee <dpmcgee@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2011-10-08pata_sis: add mode_filter method for certain sis5513 chipsetsDan McGee
This mirrors a very old commit (3160d5416f39da9d9, "sis5513: add ->udma_filter method for chipset_family >= ATA_133") to the old sis5513 IDE driver that prevents certain setups from working. UDMA6 (ATA/133) is not supported on some chipsets and we need to ensure this mode is not chosen even if a connected drive supports it. Port this old patch forward to the new PATA driver to ensure UDMA5 is the highest mode used if that is what is supported. Kernel bugzilla #41582.

2011-10-08pata_sis: extract a sis_port_base() methodDan McGee
This is similar to the existing sis_old_port_base() method. We do this same calculation and logic in multiple places (with one more to come in a future patch), so extracting it into a method makes sense.
