From 47a541c3e19374ec9f5d3d96730a922e8480dda5 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Fri, 1 Apr 2016 17:51:54 -0700 Subject: [PATCH] x86/platform: Remove unused get_bios_ebda_length() function get_bios_ebda_length() uses min_t() without including linux/kernel.h. This may result in build errors with some configurations. Since the function is not used anywhere in the kernel, let's just drop it.
