From 0852ec8cc1ac108344a219dfcab4043f407ddd9a Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Wed, 22 Aug 2007 14:01:59 -0700 Subject: [PATCH] Xen i386 xen-head.S fix sections mixup Xen i386 xen-head.S fix sections mixup xen-head.S does not come back to the data section, leaving the text section as current section. It causes problems with a slightly enhanced DEBUG_RODATA that supports CONFIG_HOTPLUG and bringing a CPU up after the text has been marked read-only: reference to early_gdt_descr causes a page fault. Updates: - It should be using pushsection/popsection. - Actually, the push/popsections around the ELFNOTEs are redundant; ELFNOTE() does its own push/popsection to put things into the appropriate .note* section anyway.
