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);

lib: add test module for CONFIG_DEBUG_VIRTUAL2017-09-09T01:26:49+00:00Florian Fainellif.fainelli@gmail.com2017-09-08T23:15:31+00:00urn:sha1:e4dace3615526fd66c86dd535ee4bc9e8c706e37
Add a test module that allows testing that CONFIG_DEBUG_VIRTUAL works
correctly, at least that it can catch invalid calls to virt_to_phys()
against the non-linear kernel virtual address map.
