Message-ID: <5088517B.1010102@zankel.net> Date: Wed, 24 Oct 2012 13:37:15 -0700 From: Chris Zankel <chris@...kel.net> To: Greg KH <greg@...ah.com> CC: linux-kernel@...r.kernel.org Subject: [PATCH stable] xtensa: add missing system calls to the syscall table Hi Greg, Could you please include this patch in the next stable tree? It adds system calls required for libc builds, so would be great to have it there.
