From bce66ca4a2f695509e1b021311eb4de1e4fdf3e4 Mon Sep 17 00:00:00 2001 From: Leonard Norrgard Date: Fri, 26 Jan 2007 00:56:38 -0800 Subject: [PATCH] [PATCH] KVM: SVM: Fix SVM idt confusion There's an obvious typo in svm_{get,set}_idt, causing it to access the ldt instead. Because these functions are only called for save/load on AMD, the bug does not impact normal operation. With the fix, save/load works as expected on AMD hosts.
