Subject: KVM: SVM: Fix SVM idt confusion
From: Leonard Norrgard <leonard.norrgard@xxxxxxxxxxx>
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.
