In a recent thread about converting kmap() to kmap_local_page(), the safety of calling kmap_local_page() was questioned.[1] "any context" should probably be enough detail for users who want to know whether or not kmap_local_page() can be called from interrupts. However, Linux still has kmap_atomic() which might make users think they must use the latter in interrupts. Add "including interrupts" for better clarity.
