i386 has task gates which support unconditional stack switching. But there are no 64bit task gates, just ISTs.

No. All interesting 32bit CPUs have SYSENTER; the only one who has SYSCALL but no SYSENTER is the K6, but it has a weird early variant of SYSCALL with more problems which was never worth supporting. -Andi -- a...@linux.intel.com -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
