Lianbo Jiang 65f750e545 x86/kdump: Export the SME mask to vmcoreinfo 
On AMD SME machines, makedumpfile tools need to know whether the crashed
kernel was encrypted.

If SME is enabled in the first kernel, the crashed kernel's page table
entries (pgd/pud/pmd/pte) contain the memory encryption mask which
makedumpfile needs to remove in order to obtain the true physical
address.

Export that mask in a vmcoreinfo variable.

 [ bp: Massage commit message and move define at the end of the
   function. ]
