* [Cluster-devel] [TRIVIAL PATCH 00/26] treewide: Add and use vsprintf extension %pSR

Remove the somewhat awkward uses of print_symbol and convert all the
existing uses to a new vsprintf pointer type of %pSR.

print_symbol can be interleaved when it is used in a sequence like:

	printk("something: ...");
	print_symbol("%s", addr);
	printk("\n");

Instead use:

	printk("something: %pSR\n", (void *)addr);

Add a new %p[SsFf]R vsprintf extension that can perform the same
symbol function/address/offset formatting as print_symbol to
reduce the number and styles of message logging functions.

print_symbol used __builtin_extract_return_addr for those architectures
like S/390 and SPARC that have offset or masked addressing.
%p[FfSs]R uses the same gcc __builtin

Use the new vsprintf extension to avoid any possible
message interleaving.
