parisc: clear floating point exception flag on SIGFPE signal

2010-07-05T18:23:07Z

commit 550f0d922286556c7ea43974bb7921effb5a5278 upstream. Clear the floating point exception flag before returning to user space. This is needed, else the libc trampoline handler may hit the same SIGFPE again while building up a trampoline to a signal handler. Fixes debian bug #559406.

drm/i915: Don't touch PORT_HOTPLUG_EN in intel_dp_detect()

2010-07-05T18:23:07Z

commit 6e0032f0ae4440e75256bee11b163552cae21962 upstream. PORT_HOTPLUG_EN has allready been setup in i915_driver_irq_postinstall(), when intel_dp_detect() runs. Delete the DP[BCD]_HOTPLUG_INT_EN defines, they are not referenced anymore.

KVM: SVM: Don't allow nested guest to VMMCALL into host

2010-07-05T18:23:06Z

This patch disables the possibility for a l2-guest to do a VMMCALL directly into the host. This would happen if the l1-hypervisor doesn't intercept VMMCALL and the l2-guest executes this instruction.

KVM: x86: Inject #GP with the right rip on efer writes

2010-07-05T18:23:05Z

This patch fixes a bug in the KVM efer-msr write path. If a guest writes to a reserved efer bit the set_efer function injects the #GP directly. The architecture dependent wrmsr function does not see this, assumes success and advances the rip. This results in a #GP in the guest with the wrong rip. This patch fixes this by reporting efer write errors back to the architectural wrmsr function.

KVM: Fix wallclock version writing race

2010-07-05T18:23:03Z

Wallclock writing uses an unprotected global variable to hold the version; this can cause one guest to interfere with another if both write their wallclock at the same time.

KVM: MMU: Don't read pdptrs with mmu spinlock held in mmu_alloc_roots

2010-07-05T18:23:03Z

On svm, kvm_read_pdptr() may require reading guest memory, which can sleep. Push the spinlock into mmu_alloc_roots(), and only take it after we've read the pdptr.

KVM: VMX: enable VMXON check with SMX enabled (Intel TXT)

2010-07-05T18:23:02Z

Per document, for feature control MSR: Bit 1 enables VMXON in SMX operation. If the bit is clear, execution of VMXON in SMX operation causes a general-protection exception. Bit 2 enables VMXON outside SMX operation. If the bit is clear, execution of VMXON outside SMX operation causes a general-protection exception. This patch is to enable this kind of check with SMX for VMXON in KVM.
