From ec80eb467171b511635b9e3086fec357f79afe3b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 16 Jan 2018 14:48:14 +0100 Subject: [PATCH] ARM: 8744/1: don't discard memblock for kexec Discarding the memblock arrays usually works, but causes problems with kexec, as pointed out by this kbuild warning: WARNING: vmlinux.o(.text+0x7c60): Section mismatch in reference from the function machine_kexec_prepare() to the function .meminit.text:memblock_is_region_memory() This lets us keep the memblock structures around whenever kexec is enabled, but otherwise still drops them.
