From 2c57bbee3cbb5f931c43e5a1e2d892d220b182c5 Mon Sep 17 00:00:00 2001 From: Stefan Tauner Date: Sat, 20 Feb 2016 20:21:58 +0000 Subject: Include sys/glibc-syscalls.h instead of inexistent sys/io.h on Android This won't make raw I/O work magically but at least it would provide iopl() if some driver requires it and there is no better alternative currently.
