Subject: [PATCH v1 2/2] arch: wire-up clone3() syscall on x86
Date: Wed, 29 May 2019 17:22:37 +0200 [thread overview]
Message-ID: <20190529152237.10719-2-christian@brauner.io> (raw)
In-Reply-To: <20190529152237.10719-1-christian@brauner.io>
Wire up the clone3() call on x86.
This patch only wires up clone3() on x86. Some of the arches look like they
need special assembly massaging and it is probably smarter if the
appropriate arch maintainers would do the actual wiring.
