[Xen-devel] [PATCH 05/15] xen/arm: p2m: Limit call to mem access code use in get_page_from_gva

2018-07-16 Thread Julien Grall
Mem access has only an impact on the hardware translation between a guest virtual address and the machine physical address. So it is not necessary to fallback to memaccess for all the other case (e.g when it is not possible to acquire the page behind the MFN). Signed-off-by: Julien Grall ---
