Message-ID: <1412760595-3935-1-git-send-email-lftan@altera.com> Date: Wed, 8 Oct 2014 17:29:26 +0800 From: Ley Foon Tan <lftan@...era.com> To: <linux-arch@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <linux-doc@...r.kernel.org> CC: Arnd Bergmann <arnd@...db.de>, Ley Foon Tan <lftan@...era.com>, <lftan.linux@...il.com>, <cltang@...esourcery.com> Subject: [PATCH v4 00/29] nios2 Linux kernel port This is the 4th version of patchset adds the Linux kernel port for Nios II processor from Altera. This version mainly update signaling patch. Not a lot has changed since v3, only patch #8, #15 and #26 have changes compare to v3. Added Acked from Arnd to patch #1 and #15. Thanks to all who provided feedback on the previous version. About Nios II Cores ------------------- Nios II is a 32-bit embedded-processor architecture designed specifically for the Altera family of FPGAs. More information is available at http://www.altera.com/devices/processor/nios2/ni2-index.html Instruction set and architecture overview documents can be found on the following page: http://www.altera.com/literature/lit-nio2.jsp Nios2 GCC port is in mainline and will be in the FSF 4.9 release. The patchset are based on v3.17 and can also be found in the following git tree: git://git.rocketboards.org/linux-socfpga-next.git nios2-upstream v4: * signal: restart handlerless case without leaving the kernel mode. * signal: set restart_block.fn to do_no_restart_syscall * signal: remove reluctant reg->status * signal: remove unused function push_cache() * ptrace: simplified arch_ptrace()
