Subject: [Qemu-devel] [PATCH 23/22] linux-user: Honor CLONE_SETTLS for openrisc
Date: Fri, 10 Feb 2017 10:01:22 +1000	[thread overview]
Message-ID: <20170210000122.4173-1-rth@twiddle.net> (raw)
In-Reply-To: <20170209045154.16868-1-rth@twiddle.net>

Threads work much better when you set the TLS register.
This was fixed in the upstream kernel for Linux 4.9.
