+From 78d1ee2f2f990b4876ce2e64c637a660911a903d Mon Sep 17 00:00:00 2001
+From: Thomas Gleixner <tglx@linutronix.de>
+Date: Tue, 3 Nov 2020 10:27:30 +0100
+Subject: [PATCH 041/323] highmem: Get rid of kmap_types.h
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+The header is not longer used and on alpha, ia64, openrisc, parisc and um
+it was completely unused anyway as these architectures have no highmem
+support.
