2008-07-07[ARM] S3C2440: Add AT2440EVB board supportRamax Lo
Add basic support for AT2440EVB board based on Samsung S3C2440 SoC. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Ramax Lo <ramaxlo@gmail.com>
2008-07-03[ARM] S3C24XX: Split serial driver into core and per-cpu driversBen Dooks
The S3C2410 serial driver in drivers/serial/s3c2410.c has been growing bigger with the addition of more variants of this hardware with the growing Samsung SoCs range. As such, it would be easier to split this code up into a core and per-cpu drivers to make driver addition easier, and the core smaller. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-06-24x86: KVM guest: Use the paravirt clocksource structs and functionsGerd Hoffmann
This patch updates the kvm host code to use the pvclock structs and functions, thereby making it compatible with Xen. The patch also fixes an initialization bug: on SMP systems the per-cpu has two different locations early at boot and after CPU bringup. kvmclock must take that in account when registering the physical address within the host.

2008-06-24x86: Add structs and functions for paravirt clocksourceGerd Hoffmann
This patch adds structs for the paravirt clocksource ABI used by both xen and kvm (pvclock-abi.h). It also adds some helper functions to read system time and wall clock time from a paravirtual clocksource (pvclock.[ch]). They are based on the xen code. They are enabled using CONFIG_PARAVIRT_CLOCK. Subsequent patches of this series will put the code in use.

2008-06-24[IA64] Eliminate NULL test after alloc_bootmem in iosapic_alloc_rte()Julia Lawall

2008-06-24xen: remove support for non-PAE 32-bitJeremy Fitzhardinge
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. Since Xen/pvops' non-PAE support has also been broken for a while, we may as well completely drop it altogether.

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: 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. Signed-off-by: Avi Kivity <avi@qumranet.com>
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.
