2008-06-30[ARM] Orion: make PCI handling code deal with Cardbus slotsLennert Buytenhek
The Cardbus connector does not have an IDSEL signal, and Cardbus cards are always the intended target of configuration transactions on their local PCI bus. This means that if the Orion's PCI bus signals are hooked up to a Cardbus slot, the same set of PCI functions will will appear 31 times, for each of the PCI device IDs 1-31 (ID 0 is the host bridge). This patch adds a function to the Orion PCI handling code that board support code can call to enable Cardbus mode. When Cardbus mode is enabled, configuration transactions on the PCI local bus are only allowed to PCI IDs 0 (host bridge) and 1 (cardbus device).

2008-06-24[GFS2] fix gfs2 block allocation (cleaned up)Benjamin Marzinski
This patch fixes bz 450641. This patch changes the computation for zero_metapath_length(), which it renames to metapath_branch_start(). When you are extending the metadata tree, The indirect blocks that point to the new data block must either diverge from the existing tree either at the inode, or at the first indirect block. They can diverge at the first indirect block because the inode has room for 483 pointers while the indirect blocks have room for 509 pointers, so when the tree is grown, there is some free space in the first indirect block. What metapath_branch_start() now computes is the height where the first indirect block for the new data block is located. It can either be 1 (if the indirect block diverges from the inode) or 2 (if it diverges from the first indirect block).

Non-PAE operation has been deprecated in Xen for a while, and is rarely tested or used. xen-unstable has now officially dropped non-PAE support.

2008-06-24KVM: VMX: Fix host msr corruption with preemption enabledAvi Kivity
Switching msrs can occur either synchronously as a result of calls to the msr management functions (usually in response to the guest touching virtualized msrs), or asynchronously when preempting a kvm thread that has guest state loaded. If we're unlucky enough to have the two at the same time, host msrs are corrupted and the machine goes kaput on the next syscall. Most easily triggered by Windows Server 2008, as it does a lot of msr switching during bootup. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-06-24KVM: ioapic: fix lost interrupt when changing a device's irqAvi Kivity
The ioapic acknowledge path translates interrupt vectors to irqs. It currently uses a first match algorithm, stopping when it finds the first redirection table entry containing the vector. That fails however if the guest changes the irq to a different line, leaving the old redirection table entry in place (though masked). Result is interrupts not making it to the guest. Fix by always scanning the entire redirection table. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-06-24KVM: MMU: Fix oops on guest userspace access to guest pagetableAvi Kivity
KVM has a heuristic to unshadow guest pagetables when userspace accesses them, on the assumption that most guests do not allow userspace to access pagetables directly. Unfortunately, in addition to unshadowing the pagetables, it also oopses. This never triggers on ordinary guests since sane OSes will clear the pagetables before assigning them to userspace, which will trigger the flood heuristic, unshadowing the pagetables before the first userspace access. One particular guest, though (Xenner) will run the kernel in userspace, triggering the oops. Since the heuristic is incorrect in this case, we can simply remove it.

2008-06-24KVM: MMU: large page update_pte issue with non-PAE 32-bit guests (resend)Marcelo Tosatti
kvm_mmu_pte_write() does not handle 32-bit non-PAE large page backed guests properly. It will instantiate two 2MB sptes pointing to the same physical 2MB page when a guest large pte update is trapped. Instead of duplicating code to handle this, disallow directory level updates to happen through kvm_mmu_pte_write(), so the two 2MB sptes emulating one guest 4MB pte can be correctly created by the page fault handling path.

2008-06-24KVM: MMU: Fix rmap_write_protect() hugepage iteration bugMarcelo Tosatti
rmap_next() does not work correctly after rmap_remove(), as it expects the rmap chains not to change during iteration. Fix (for now) by restarting iteration from the beginning. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-06-24KVM: close timer injection race window in __vcpu_runMarcelo Tosatti
If a timer fires after kvm_inject_pending_timer_irqs() but before local_irq_disable() the code will enter guest mode and only inject such timer interrupt the next time an unrelated event causes an exit. It would be simpler if the timer->pending irq conversion could be done with IRQ's disabled, so that the above problem cannot happen. For now introduce a new vcpu requests bit to cancel guest entry.

2008-06-24KVM: Fix race between timer migration and vcpu migrationMarcelo Tosatti
A guest vcpu instance can be scheduled to a different physical CPU between the test for KVM_REQ_MIGRATE_TIMER and local_irq_disable(). If that happens, the timer will only be migrated to the current pCPU on the next exit, meaning that guest LAPIC timer event can be delayed until a host interrupt is triggered. Fix it by cancelling guest entry if any vcpu request is pending. This has the side effect of nicely consolidating vcpu->requests checks.
