Module Name:    src
Committed By:   maxv
Date:           Sat Feb 23 10:43:37 UTC 2019

Modified Files:
        src/sys/arch/x86/x86: pmap.c
        src/sys/dev/nvmm/x86: nvmm_x86_vmx.c

Log Message:
Add support for CPUs that don't have the EPT_{A,D} bits.

On such CPUs, these bits are ignored by the hardware. We don't care about
setting them, however, we must always assume they are set. Modify the pmap
code to do that.

While here, in pmap_ept_remove_pte, don't flush the TLB when it's not
needed.

Tested on an old Intel Celeron.
