From 5bdb0a7cad05df35cd87ebce683eda032a8abc87 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Tue, 18 Dec 2018 18:06:14 +0100 Subject: [PATCH] lib: crc32: mark static variable as __efi_runtime_data In commit 483dbab9f931 ("lib: crc32: mark function crc32() as __efi_runtime") one local static variable was missed. It did not end up in the __efi_runtime_data section as it should. If CONFIG_DYNAMIC_CRC_TABLE=y a data abort execption may occur when the UEFI payload calls the SetVirtualAddressMap() runtime service.
