From 09aaa9748aa1aea0b2fa339a823b754285c8ad6c Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Sun, 4 May 2014 10:00:49 -0700 Subject: x86, espfix: Make espfix64 a Kconfig option, fix UML commit 197725de65477bc8509b41388157c1a2283542bb upstream. Make espfix64 a hidden Kconfig option. This fixes the x86-64 UML build which had broken due to the non-existence of init_espfix_bsp() in UML: since UML uses its own Kconfig, this option does not appear in the UML build. This also makes it possible to make support for 16-bit segments a configuration option, for the people who want to minimize the size of the kernel. Reported-by: Ingo Molnar Signed-off-by: H.
