Jiri Kosina 4545c89880 x86: introduce kaslr_offset() ... Offset that has been chosen for kaslr during kernel decompression can be easily computed as a difference between _text and __START_KERNEL. We are already making use of this in dump_kernel_offset() notifier and in arch_crash_save_vmcoreinfo(). Introduce kaslr_offset() that makes this computation instead of hard-coding it, so that other kernel code (such as live patching) can make use of it. Also convert existing users to make use of it. This patch is equivalent transofrmation without any effects on the resulting code: $ diff -u vmlinux.old.asm vmlinux.new.asm --- vmlinux.old.asm 2015-04-28 17:55:19.520983368 +0200 +++ vmlinux.new.asm 2015-04-28 17:55:24.141206072 +0200 @@ -1,5 +1,5 @@ -vmlinux.old: file format elf64-x86-64 +vmlinux.new: file format elf64-x86-64 Disassembly of section .text: $ Acked-by: Borislav Petkov <bp@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>		2015-04-29 16:51:33 +02:00
