[ Upstream commit e792ff804f49720ce003b3e4c618b5d996256a18 ]
Use the generic kretprobe trampoline handler. Don't use framepointer verification.

There's no explanation here why this is good idea for -stable.
Plus, this seems to depend on commit 66ada2ccae4ed4dd07ba91df3b5fdb4c11335bd1 which is not present in stable, so this will likely not build due to lack of __kretprobe_trampoline_handler symbol. (I don't have ia64 to verify):
$ grep -ri __kretprobe_trampoline_handler . ./arch/ia64/kernel/kprobes.c: regs->cr_iip = __kretprobe_trampoline_handler(regs, kretprobe_trampoline, NULL); $
I believe it should be dropped.
Best regards, Pavel ...
