Subject: [PATCH 1/2] parisc: regs_return_value() should return gpr28
Date: Thu, 4 Apr 2019 18:16:03 +0200 [thread overview]
Message-ID: <20190404161604.6165-2-svens@stackframe.org> (raw)
In-Reply-To: <20190404161604.6165-1-svens@stackframe.org>
While working on kretprobes for PA-RISC i was wondering while the
kprobes sanity test always fails on kretprobes. This is caused by
returning gpr20 instead of gpr28.
