------------------------------------------------------ From: Christophe Leroy christophe.leroy@c-s.fr Subject: lib/test_debug_virtual.c: fix build failure

On several arches, virt_to_phys() is in io.h

Build fails without it:

CC lib/test_debug_virtual.o lib/test_debug_virtual.c: In function 'test_debug_virtual_init': lib/test_debug_virtual.c:26:7: error: implicit declaration of function 'virt_to_phys' [-Werror=implicit-function-declaration] pa = virt_to_phys(va); ^
