From 206f25a8319b312b9983953a308b0e38e1943c1c Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 18 Apr 2016 09:42:11 -0700 Subject: x86/KASLR: Remove unneeded boot_params argument Since the boot_params can be found using the real_mode global variable, there is no need to pass around a pointer to it. This slightly simplifies the choose_kernel_location function and its callers.
