From 6a542d1d5f6c814fd3643b43e85b21757c1e363b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 8 Jun 2020 12:21:07 -0400 Subject: kill signal_pt_regs() Once upon at it was used on hot paths, but that had not been true since 2013. IOW, there's no point for arch-optimized equivalent of task_pt_regs(current) - remaining two users are not worth bothering with.
