[Xen-devel] [PATCH 0 of 2] Add libxc API that sets mem_access type for an array of gfns

[Aravindh Puthiyaparambil <aravindh@xxxxxxxxxxxx>]

When the mem_access type needs to be changed for multiple discontiguous gfns, 
calling xc_hvm_set_mem_access() multiple times does not perform very well. The 
main pain points are the multiple libxc calls themselves plus the multiple 
map_domain_page() / unmap_domain_page() and ept_sync_domain() calls for each 
ept_set_entry(gfn). The following patches adds a new mem_access API that sets 
the mem_access type for an array of guest physical addresses in one libxc call 
with minimal map_domain_page() / unmap_domain_page() and ept_sync_domain() 
calls.
