Subject: [PATCH v5 7/9] x86: Enable Syscall User Dispatch
Date: Mon, 10 Aug 2020 19:26:34 -0400 [thread overview]
Message-ID: <20200810232636.1415588-8-krisman@collabora.com> (raw)
In-Reply-To: <20200810232636.1415588-1-krisman@collabora.com>
Syscall User Dispatch requirements are fully supported in x86. This
patch flips the switch, marking it as supported. This was tested
against Syscall User Dispatch selftest.
