Subject: Re: [PATCH v1 5/7] xen/x86: move declaration from mem_access.h to
altp2m.h

Memory access and ALTP2M are two seperate features, and each could be
controlled via VM_EVENT or ALTP2M. In order to avoid implicit
declaration when ALTP2M=y and VM_EVENT=n on compiling hvm.o/altp2m.o,
we move declaration of the following functions from <asm/mem_access.h> to
<asm/altp2m.h>:
- p2m_set_suppress_ve
- p2m_set_suppress_ve_multi
- p2m_get_suppress_ve
Potential error on altp2m.c also breaks Misra Rule 8.4.
