From 13cad9851ef1d004640991d45227dd35c08f45fc Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 21 May 2020 22:05:45 +0200 Subject: x86/entry: Convert reschedule interrupt to IDTENTRY_SYSVEC_SIMPLE The scheduler IPI does not need the full interrupt entry handling logic when the entry is from kernel mode. Use IDTENTRY_SYSVEC_SIMPLE and spare all the overhead.
