 /* sys/io.h provides iopl(2) and x86 I/O port access functions (inb, outb etc).

+ * On Android we don't have the header file and no way for I/O port access at all. However, sys/glibc-syscalls.h
+ * refers to an iopl implementation and we therefore include at least that one for now. On non-Android we assume
