From 52760e9c5e677b76c81e921bbab95da26478f425 Mon Sep 17 00:00:00 2001 From: Ian Moffett Date: Tue, 2 Jul 2024 21:15:01 -0400 Subject: kernel/amd64: Add INTRENTRY() and TRAPENTRY() Add macros that perform certain operations before invoking the actual handler. This will be useful in the future for more complicated operations that need to be done before the handler is ran.
