35f5eef658 Add page mask MACRO
Add 'CPU_PAGE_MASK' used for calculate address,
Change IA32E_REF_MASK from 0x7ffffffffffff000 to 0x000ffffffffff000
for MMU/EPT entry, bit62:52(ignore) bit63(VE/XD)
if we want to obtain the address from the MMU/EPT entry,need to clear
bit63:52 by IA32E_REF_MASK

c451f2e4fa add create secure world ept API
This patch is prepared for enabling secure world feature.
this api will create new eptp for secure world, whose PDPT
entries are copied form normal world,the PML4/PDPT for secure
world are separated from Normal World, PD/PT are shared in the
Secure World's EPT and Normal World's EPT.Secure world can
access Normal World's memory, but Normal World can not access
Secure World's memory
This function implemented:
-- Unmap specific memory from guest ept mapping
-- Copy PDPT from Normal world to Secure world
-- Map specific memory for Secure world
-- Unmap specific memory from SOS ept mapping
