Subject: [PATCH RFC 3/3] xen/Kconfig: add XEN_TIME_VSYSCALL option
Date: Mon, 28 Dec 2015 21:52:37 +0000	[thread overview]
Message-ID: <1451339557-24473-4-git-send-email-joao.m.martins__27028.1340498061$1451339705$gmane$org@oracle.com> (raw)
In-Reply-To: <1451339557-24473-1-git-send-email-joao.m.martins@oracle.com>

This option enables support for pvclock vsyscall/vdso
support on Xen. Default is off, since Xen doesn't
expose yet the PVCLOCK_TSC_STABLE_BIT flag.
