Somehow in all of the chaos this one line bug fix got merged with
the another patch and was then discarded when issues were found
with that other patch.
From: Vivek Goyal <[email protected]>
A minor fix to the patch which remembers the location of where i8259 is
connected. Now counter i has been replaced by apic. counter i is having
some junk value which was leading to non-detection of i8259 connected to
IOAPIC.
