2008-03-04dmaengine: add driver for Freescale MPC85xx DMA controllerZhang Wei
The driver implements DMA engine API for Freescale MPC85xx DMA controller, which could be used by devices in the silicon. The driver supports the Basic mode of Freescale MPC85xx DMA controller. The MPC85xx processors supported include MPC8540/60, MPC8555, MPC8548, MPC8641 and so on. The MPC83xx(MPC8349, MPC8360) are also supported.

2008-03-04freezer vs stopped or tracedRoland McGrath
This changes the "freezer" code used by suspend/hibernate in its treatment of tasks in TASK_STOPPED (job control stop) and TASK_TRACED (ptrace) states. As I understand it, the intent of the "freezer" is to hold all tasks from doing anything significant. For this purpose, TASK_STOPPED and TASK_TRACED are "frozen enough". It's possible the tasks might resume from ptrace calls (if the tracer were unfrozen) or from signals (including ones that could come via timer interrupts, etc). But this doesn't matter as long as they quickly block again while "freezing" is in effect. Some minor adjustments to the signal.c code make sure that try_to_freeze() very shortly follows all wakeups from both kinds of stop. This lets the freezer code safely leave stopped tasks unmolested. Changing this fixes the longstanding bug of seeing after resuming from suspend/hibernate your shell report "[1] Stopped" and the like for all your jobs stopped by ^Z et al, as if you had freshly fg'd and ^Z'd them. It also removes from the freezer the arcane special case treatment for ptrace'd tasks, which relied on intimate knowledge of ptrace internals.

2008-03-04KVM: VMX: Avoid rearranging switched guest msrs while they are loadedAvi Kivity
KVM tries to run as much as possible with the guest msrs loaded instead of host msrs, since switching msrs is very expensive. It also tries to minimize the number of msrs switched according to the guest mode; for example, MSR_LSTAR is needed only by long mode guests. This optimization is done by setup_msrs(). However, we must not change which msrs are switched while we are running with guest msr state: - switch to guest msr state - call setup_msrs(), removing some msrs from the list - switch to host msr state, leaving a few guest msrs loaded An easy way to trigger this is to kexec an x86_64 linux guest. Early during setup, the guest will switch EFER to not include SCE. KVM will stop saving MSR_LSTAR, and on the next msr switch it will leave the guest LSTAR loaded. The next host syscall will end up in a random location in the kernel. Fix by reloading the host msrs before changing the msr list. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-03-04KVM: MMU: Fix race when instantiating a shadow pteAvi Kivity
For improved concurrency, the guest walk is performed concurrently with other vcpus. This means that we need to revalidate the guest ptes once we have write-protected the guest page tables, at which point they can no longer be modified. The current code attempts to avoid this check if the shadow page table is not new, on the assumption that if it has existed before, the guest could not have modified the pte without the shadow lock. However the assumption is incorrect, as the racing vcpu could have modified the pte, then instantiated the shadow page, before our vcpu regains control: vcpu0 vcpu1 fault walk pte modify pte fault in same pagetable instantiate shadow page lookup shadow page conclude it is old instantiate spte based on stale guest pte We could do something clever with generation counters, but a test run by Marcelo suggests this is unnecessary and we can just do the revalidation unconditionally. The pte will be in the processor cache and the check can be quite fast. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-03-04KVM: Route irq 0 to vcpu 0 exclusivelyAvi Kivity

2008-03-04cciss: remove READ_AHEAD define and use block layer defaultsMike Miller
This patch removes the #define READ_AHEAD 1024 from the driver and uses the block layer defaults, instead. We have found that under certain workloads the setting can cause a disk connected to the e200 controller to go offline. If the disk hiccups the link may try to downshift but the controller is never notified that the link successfully completed the renegotiation. We've also found that performance using the block layer default of 32 pages was on par with the 1024 setting. We tried setting it to zero at one time based on info from our firmware guys but that killed performance. Turns out we were talking about 2 different read ahead settings.
