Subject[PATCH 4.14 104/105] lib: fix build failure in CONFIG_DEBUG_VIRTUAL test
Date
4.14-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);
^
