This reverts commit 77fa5e15c933a1ec812de61ad709c00aa51e96ae.
Since the upstream commit e792ff804f49720ce003b3e4c618b5d996256a18 depends on the generic kretprobe trampoline handler, which was introduced by commit 66ada2ccae4e ("kprobes: Add generic kretprobe trampoline handler") but that is not ported to the stable kernel because it is not a bugfix series. So revert this commit to fix a build error.
NOTE: I keep commit a7fe2378454c ("ia64: kprobes: Fix to pass correct trampoline address to the handler") on the tree, that seems just a cleanup without the original reverted commit, but it would be better to use dereference_function_descriptor() macro instead of accessing descriptor's field directly.

Thanks for this, I'll queue it up after this round of stable releases are out.
