/*
 * This function is _not_ called directly.  It is jumped to from PLT when 
 * attempting to use a symbol that has not yet been resolved.  The first 
 * time a jump symbol (such as a function call inside a shared library) 
 * is used (before it gets resolved) it will jump here.  When we get called 
 * the stack contains reloc_offset and tpnt is in MOF.
 *
 * We save all the registers, setup R10 and R11 with the right arguments 
 * then call _dl_linux_resolver(tpnt, reloc_offset). _dl_linux_resolver() 
 * figures out where the jump symbol is _really_ supposed to have jumped to 
 * and returns that to us.  Once we have that, we overwrite tpnt with this 
 * fixed up address. We then clean up after ourselves, put all the registers 
 * back how we found them, then we jump to where the fixed up address, which 
 * is where the jump symbol that got us here really wanted to jump to in the 
 * first place.
