Subject: [PATCH 0/2] arm64: Fix single-stepping with reverse debugging
Date: Wed, 3 Jun 2020 16:10:31 +0100 [thread overview]
Message-ID: <20200603151033.11512-1-will@kernel.org> (raw)
Hi all,
This series fixes a bug in our hardware single-step and ptrace logic that
was reported by Luis after seeing some GDB testsuite failures. The second
patch is cosmetic, but I was in the area.
Cheers,
Will
