From b767fe5de0b4a5057b070d8cdefdcf6740733d6e Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Sun, 7 Apr 2024 17:05:55 +0800 Subject: [PATCH] x86/entry: Merge thunk_64.S and thunk_32.S into thunk.S The code in thunk_64.S and thunk_32.S are exactly the same except for the comments. Merge them in to thunk.S. And since thunk_32.S was originated from thunk_64.S, the new merged thunk.S is actually renamed from thunk_64.S.
