4 Subject: parisc: regs_return_value() should return gpr28
6 From: Sven Schnelle <svens@stackframe.org>
8 commit 45efd871bf0a47648f119d1b41467f70484de5bc upstream.
10 While working on kretprobes for PA-RISC I was wondering while the
11 kprobes sanity test always fails on kretprobes. This is caused by
12 returning gpr20 instead of gpr28.
