From a39f39cdd8be5cd3e7a8b696a463b621e3d827e0 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 29 Jul 2018 09:49:04 +0200 Subject: efi_loader: update runtime services table crc32 The crc32 of the runtime services table must be updated after detaching. efi_update_table_header_crc32() must be __efi_runtime.
