[Bug translator/5667] New: Exploit kprobe.symbol_name for function boundary tracing

["ananth at in dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

Further to bug 4311, one could explore the possibility of exploiting the
(already existing) struct kprobe.symbol_name field for function address
resolution. At a minimum, the translator may have to just populate this field
and explicitly set struct kprobe.addr to 0x00. The kernel will try to resolve
this symbol, and in any case, probe registration will fail if the kernel fails
to resolve the symbol.

Kernels >= 2.6.19 incorporate kprobe.symbol_name
