From 5fb0ba537ab15f9c83afd9a939cf57c84d443856 Mon Sep 17 00:00:00 2001 From: Danny Holman Date: Mon, 27 May 2024 14:25:27 -0500 Subject: arch: i386: pmem: refactor the physical MM Refactor the physical memory manager to be dramatically simpler. The new design uses only a single freelist, and only uses temporary mappings where needed.
