[ Upstream commit 386744425e35e04984c6e741c7750fd6eef1a9df ]
This header file uses the enum dma_data_direction and struct page types without explicitly including the corresponding header files. This makes it rely on the includer to have included the proper headers before.
To fix this, include linux/dma-direction.h and forward-declare struct page. The swiotlb_free() function is also annotated __init, therefore requires linux/init.h to be included as well.
