Subject: [PATCH 2.6.21-rc1] Extend print_symbol capability TRY #2

This is try #2 for this patch, with corrections based on feedback. 
It is the same as the previous patch except:
(1) The function has been renamed from lookup_symbol to sprint_symbol
    as requested by Paulo Marques.
(2) I fixed the "return NULL;" to "return;" as pointed out by Paulo Marques
    for the case where the kallsyms function is not selected in .config
(3) I changed EXPORT_SYMBOL to EXPORT_SYMBOL_GPL as
    requested by Roman Zippel. (Andrew, I thought you said you changed this,
    but I didn't see it in mm1).

I hope this patch attaches with proper spacing and without word wrap.
If it doesn't, my apologies (I'm using Thunderbird, but suggestions 
welcome).

Original comment:

Today's print_symbol function dumps a kernel symbol with printk.
This patch extends the functionality of kallsyms.c so that the symbol
lookup function may be used without the printk.  This is
useful for modules that want to dump symbols elsewhere, for
example, to debugfs.  I intend to use the new function call in the
GFS2 file system (which will be a separate patch).
