ACPI: fix two IRQ8 issues in IOAPIC mode
Use mp_irqs[] to get PNP device's interrupt polarity and trigger. There are two reasons to do this: 1. BIOS bug for PNP interrupt 2. BIOS explictly does override mp_irqs[] should cover all the cases. http://bugzilla.kernel.org/show_bug.cgi?id=5243 http://bugzilla.kernel.org/show_bug.cgi?id=7679 http://bugzilla.kernel.org/show_bug.cgi?id=9153 [lenb: fixed !IOAPIC and 64-bit !SMP builds] Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
