commit b5a44a6a471aafd3677659a610f32468c40a666b Author: Noah Goldstein Date: Tue Sep 21 18:31:49 2021 -0500 x86: Modify ENTRY in sysdep.h so that p2align can be specified No bug. This change adds a new macro ENTRY_P2ALIGN which takes a second argument, log2 of the desired function alignment. The old ENTRY(name) macro is just ENTRY_P2ALIGN(name, 4) so this doesn't affect any existing functionality.
