From 217d115cd5d7d2bef7db7839b93ce5dc2867c392 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 15 Oct 2007 13:57:46 +0200 Subject: x86: merge some trivially mergeable headers Merge errno.h, resource.h, rtc.h, sections.h, serial.h and sockios.h, where i386 and x86_64 have no or only trivial comment/include guard differences. Build tested on both 32-bit and 64-bit, and booted on 64-bit.
