It can change from one vmentry to the next, so I'm not sure how you'd do that. > > + nested_vmx_disable_intercept_for_msr( > > + msr_bitmap_l1, msr_bitmap_l0, > > + APIC_BASE_MSR + (APIC_TASKPRI >> 4), > > + MSR_TYPE_W); > > I'd vote for indenting the parameters properly (even though we exceed 80 > chars by 1 then :) ) Ok, will do. Regarding the WARN, I'm undecided. I like the idea of not calling a function that works on MSR bitmaps unless you have one... Paolo
