In order to call kmap_atomic() etc, we need to include linux/highmem.h:
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c: In function 'vmw_bo_cpu_blit_line':
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:377:4: error: implicit declaration of
function 'kunmap_atomic'; did you mean 'in_atomic'?
[-Werror=implicit-function-declaration]
377 | kunmap_atomic(d->src_addr);
| ^~~~~~~~~~~~~

drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:391:5: error: implicit declaration of
function 'kmap_atomic_prot' [-Werror=implicit-function-declaration]
391 | kmap_atomic_prot(d->dst_pages[dst_page],
| ^~~~~~~~~~~~~~~~
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:390:16: warning: assignment to 'u8 *' {aka
'unsigned char *'} from 'int' makes pointer from integer without a cast
