On 32bit, 'long' is still 32bit, did you want to cast to 'long
An encrypted VMA will have KeyID stored in vma->vm_page_prot. This way
we don't need to do anything special to setup encrypted page table
entries and don't need to reserve space for KeyID in a VMA.
This patch changes _PAGE_CHG_MASK to include KeyID bits. Otherwise they
are going to be stripped
