I have merged Bob Montgomery's IA64 drivers into the current oprofile 
CVS. I have put the patch (ia64g.patch) and some information about the 
IA64 patch support at http://people.redhat.com/wcohen/. The ia64 
oprofile support is work in progress. There are a number of known 
problems with the code (there are problably some unknown problems too):

	-This code will not work with kernels that do not export the
	 syscall table.
	-The code will only work with IA64 SMP kernels.
	-The code needs perfmon support in the kernel.
	-There are problems with determining the executable name from
	 the mmap information in /proc. The IA64 kernel does not put
	 the executable name as the first entry.
	-For some kernels the IA64 oprofile module compilation will
	 generate warnings.
	-OProfile daemon currently only uses the low 32-bits of the
	 address samples may be miss attributed because of the loss of
  	 the upper 32-bits of the address.
