The patch titled
Xen i386 xen-head.S fix sections mixup
has been removed from the -mm tree. Its filename was
xen-i386-xen-heads-fix-sections-mixup-update-2.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Xen i386 xen-head.S fix sections mixup
From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxx>
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.
