> GNU Mach hangs during SMP startup when the firmware exposes more CPUs than
> NCPUS. The broadcast INIT/STARTUP IPI starts every exposed AP, including the
> ones the parser rejected, and the zero-initialised cpu_id_lut made those APs
> alias kernel ID 0 and corrupt the BSP's per-CPU and GDT state.
>
> The series bounds cpu_lapic_list at insertion, keeps the BSP and skips
> unusable MADT entries, parks rejected APs, panics with a reason on APIC
> failure, and clarifies --enable-ncpus.

> Changes since v1:
> - former patch 2 split into four patches;
> - former patch 3 now also covers x86_64;
> - patch 1 drops the APIC ID range test.

> The series applies to gnumach c5701c1c ("Raise NET_MAX_FILTER").
