Hi,

Kernel test bot reported that the ia64 build error on stable 4.19.y because
of the commit d3380de483d5 ("ia64: kprobes: Use generic kretprobe trampoline
handler").
I also found that this commit was involved by the backporting of commit
f5f96e3643dc ("ia64: kprobes: Fix to pass correct trampoline address to the
handler"), and this 2nd commit was backported wrong way. Actually, this 2nd
commit aimed to use dereference_function_descriptor() in kprobes@ia64, but
the comment (and Fixes tag) points the 1st commit. Thus I guess this mistake
happened.

So I re-backport the upstream commit a7fe2378454c ("ia64: kprobes: Fix to
pass correct trampoline address to the handler") correctly, without involving
the 1st commit.

Thank you,

---
