This is the 5th version of patchset adds the Linux kernel port for Nios II processor from
Altera. All of the feedback from v4 patchseries has been addressed. Note, only
patch #4, #17, #21 and #29 have changes compare to v4. 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 v3.18-rc1 and can also be found in the following git tree:
git://git.rocketboards.org/linux-socfpga-next.git nios2-upstream

v5:
* handle multiple pending signal before return to userland
* stop timer for case CLOCK_EVT_MODE_ONESHOT
* add comment to timer driver
* remove unused function, get_fb_unmapped_area()
* add irq_work.h to Kbuild
