[Xen-devel] compile error with current xen/master

[Josip Rodin <joy@xxxxxxxxxxxxxx>]

Hi,

I updated my previously-working pvops kernel (git pull origin xen/master)
and reran make oldconfig, where I made some fairly random choices for the
new functionality that I'm not sure I want :) and then make failed with
the following output (with CONFIG_DEBUG_SECTION_MISMATCH=y):

[...]
Kernel: arch/x86/boot/bzImage is ready  (#3)
  Building modules, stage 2.
  MODPOST 1651 modules
WARNING: drivers/net/xen-netchannel2/netchannel2.o(.init.text+0x23): Section 
mismatch in reference from the function init_module() to the function 
.exit.text:netfront2_exit()
The function __init init_module() references
a function __exit netfront2_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
netfront2_exit() so it may be used outside an exit section.

WARNING: drivers/net/xen-netchannel2/netchannel2.o(.data+0x388): Section 
mismatch in reference from the variable netfront2 to the function 
.devinit.text:netfront_probe()
The variable netfront2 references
the function __devinit netfront_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
