[ Upstream commit 083db67648 ]
The __raw_callee_save_*() functions have an ELF symbol size of zero,
which confuses objtool and other tools.
Fixes a bunch of warnings like the following:
arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_pte_val() is missing an ELF size annotation
arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_pgd_val() is missing an ELF size annotation
arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_make_pte() is missing an ELF size annotation
arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_make_pgd() is missing an ELF size annotation

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
