linux-toradex.git/include/asm-x86/tlbflush.h, branch v2.6.27.27 Linux kernel for Apalis and Colibri modules x86: prevent PGE flush from interruption/preemption 2008-05-23T16:16:15+00:00 Ingo Molnar mingo@elte.hu 2008-05-12T19:21:15+00:00 b1979a5fda7869a790f4fd83fb06c78498d26ba1 CR4 manipulation is not protected against interrupts and preemption, but KVM uses smp_function_call to manipulate the X86_CR4_VMXE bit either from the CPU hotplug code or from the kvm_init call. We need to protect the CR4 manipulation from both interrupts and preemption. Original bug report: http://lkml.org/lkml/2008/5/7/48 Bugzilla entry: http://bugzilla.kernel.org/show_bug.cgi?id=10642 This is not a regression from 2.6.25, it's a long standing and hard to trigger bug.

CR4 manipulation is not protected against interrupts and preemption,
but KVM uses smp_function_call to manipulate the X86_CR4_VMXE bit
either from the CPU hotplug code or from the kvm_init call.

We need to protect the CR4 manipulation from both interrupts and
preemption.

This is not a regression from 2.6.25, it's a long standing and hard to
trigger bug.
