commit 4204f40942661cdbae0c2695e523d0944ffaebd9 Author: Paul Menzel paulepanter@users.sourceforge.net Date: Tue Apr 23 14:34:43 2013 +0200
x86 I/O APIC: Make functions `io_apic_{read,write}()` public
Some LPC initialiation can save some lines of code when being able to use the functions `io_apic_read()` and `io_apic_write()`.
