2025-11-19kern/amd64: mp: Load per-core GDT/IDTIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>

2025-11-19kern: proc: Add enhanced processor arbitrationIan Moffett
Unlike the previouses systems where there was a global arbiter and a shared lock, rv7 derives a zero-based processor index by using the lower 8 bits of the pid MOD the core count. This significantly reduces contention. Signed-off-by: Ian Moffett <ian@osmora.org>
