[Xen-devel] [PATCH] xen: fix p2m section mismatches

[Randy Dunlap <randy.dunlap@xxxxxxxxxx>]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

Fix section mismatch warnings:
set_phys_range_identity() is called by __init xen_set_identity(),
so also mark set_phys_range_identity() as __init.
then:
__early_alloc_p2m() is called set_phys_range_identity(), so also mark
__early_alloc_p2m() as __init.

WARNING: arch/x86/built-in.o(.text+0x7856): Section mismatch in reference from 
the function __early_alloc_p2m() to the function .init.text:extend_brk()
The function __early_alloc_p2m() references
the function __init extend_brk().
This is often because __early_alloc_p2m lacks a __init 
annotation or the annotation of extend_brk is wrong.

WARNING: arch/x86/built-in.o(.text+0x7967): Section mismatch in reference from 
the function set_phys_range_identity() to the function .init.text:extend_brk()
The function set_phys_range_identity() references
the function __init extend_brk().
This is often because set_phys_range_identity lacks a __init 
annotation or the annotation of extend_brk is wrong.
