2009-09-10KVM: VMX: Check cpl before emulating debug register accessAvi Kivity
Debug registers may only be accessed from cpl 0. Unfortunately, vmx will code to emulate the instruction even though it was issued from guest userspace, possibly leading to an unexpected trap later.

2009-09-10KVM: VMX: Conditionally reload debug register 6Avi Kivity
Only reload debug register 6 if we're running with the guest's debug registers. Saves around 150 cycles from the guest lightweight exit path. dr6 contains a couple of bits that are updated on #DB, so intercept that unconditionally and update those bits then.

2009-09-10KVM: Use thread debug register storage instead of kvm specific dataAvi Kivity
Instead of saving the debug registers from the processor to a kvm data structure, rely in the debug registers stored in the thread structure. This allows us not to save dr6 and dr7. Reduces lightweight vmexit cost by 350 cycles, or 11 percent. Signed-off-by: Avi Kivity <avi@redhat.com>
2009-09-10KVM guest: do not batch pte updates from interrupt contextMarcelo Tosatti
Commit b8bcfe997e4 made paravirt pte updates synchronous in interrupt context. Unfortunately the KVM pv mmu code caches the lazy/nonlazy mode internally, so a pte update from interrupt context during a lazy mmu operation can be batched while it should be performed synchronously. https://bugzilla.redhat.com/show_bug.cgi?id=518022 Drop the internal mode variable and use paravirt_get_lazy_mode(), which returns the correct state.

2009-09-10sparc64: Implement a real set_perf_counter_pending().David S. Miller
When the perf counter subsystem needs to reschedule work out from an NMI, it invokes set_perf_counter_pending(). This triggers a non-NMI irq which should invoke perf_counter_do_pending(). Currently this won't trigger because sparc64 won't trigger the perf counter subsystem from NMIs, but when the HW counter support is added it will. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-09-10[ARM] pxa/colibri: add UART MFP configuration for the PXA320 moduleAlex Roman
This patch configures the MFP pads for UART1, UART2, UART3 for the Toradex Colibri PXA320 module. Previously they were just not configured resulting in just the first UART working because it was the only one that was configured by the bootloader (Toradex EBOOT in our case). This patch is against vanilla 2.6.30 and has been tested with the Toradex Orchid carrier board (all three UARTs were functional).
