| |
From: Ard Biesheuvel <ardb@kernel.org>
The Xen PVH startup code does not need to live in .head.text, given that its entry point is not at a fixed offset, and is communicated to the host/VMM via an ELF note.
So move it out of .head.text into another code section. To avoid spurious warnings about references to .init code, move it into .ref.text rather than .text. (Note that the ELF note itself is not .init and so moving this code into .init.text would result in warnings as well)
