Hi,

> Try this patch, thanks.

I believe your patch to rcutree_plugin.h and rcutree.h worked, but I'm
now still having difficulty with con_init():

  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
drivers/built-in.o: In function `con_init':
vt.c:(.init.text+0x3a6b): undefined reference to `.L1626'
make: *** [.tmp_vmlinux1] Error 1

Is this also a bug, or am I doing something wrong? Is there something
I can do to produce more debugging info, or troubleshoot it further?

This is 2.6.32-rc5-git3, gcc-3.4.4, glibc-2.3.6, and binutils-2.20.51.0.2.

Thanks,
Alex
