Prototype continuations don't use a single tab indent. Either two
tabs (my preference) or after the opening brace. I.e.:

static unsigned long
va_alloc(struct vmap_area *va, struct rb_root *root, struct list_head *head,
unsigned long size, unsigned long align, unsigned long vstart,
unsigned long vend)


Otherwise looks good:
