4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe Leroy christophe.leroy@c-s.fr
commit 10fdf838e5f540beca466e9d1325999c072e5d3f upstream.
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); ^
