[Xen-devel] [PATCH 14/22] mini-os: add map_frame_virt() function

2016-08-23 Thread Juergen Gross
Add a function map_frame_virt() to map a given frame and return its virtual address. On arm we just use the frame physical address, while on x86 we take a page from the virtual kernel area. For this purpose make this area available even in case of undefined CONFIG_BALLOON. Signed-off-by: Juergen
