2021-04-04SMP: fix getting the interrupt stack address and sizeSamuel Thibault
* i386/i386at/boothdr.S (_eintstack): Add missing common. * i386/xen/xen_boothdr.S (_eintstack): Add missing common. * x86_64/xen/xen_boothdr.S (_eintstack): Add missing common. * i386/i386/mp_desc.c (intstack, eintstack): Add missing underscore.
2021-04-04Add ioapic support disabled by defaultDamien Zammit
Use --enable-ncpus=x --enable-apic where x > 1 for SMP+APIC support. Use neither for no SMP and old PIC support. Message-Id: <20210404050812.145483-1-damien@zamaudio.com>
