From: Bob Moore <robert.mo...@intel.com> ACPICA commit ac1564c26d239348ef13455f61d5616f3961ff43
Used by the ACPICA applications. This patch is a bit broken due to non-portable <errno.h> inclusion as on some platforms, there is no such a header file for their lib-c exports. Fortunately, Linux doesn't compile utfileio.c for either the kernel space ACPICA core (drivers/acpi/acpica) or the userspace ACPICA tools (tools/power/acpi) for now, so it's safe to leave this patch as it is.
