 Hi, Tristan

 GET_THIS_PADDR translate from only per_cpu virtual address
 to per_cpu physcal address.
Yes.

 per_cpu address is in TLB.
Is it true even within MCA handler ?
Yes, TR is unchanged by SAL/PAL when INIT is occerred.

Hi, Tristan

GET_THIS_PADDR translate from only per_cpu virtual address 
to per_cpu physcal address.
per_cpu address is in TLB.
So GET_THIS_PADDR don't cause TLB fault.
