I gave "reviewed-by" to five patches (01, 02, 13, 22, and 33) that actually fix 
or improve pre-nanoMIPS code segments (all these issues exist regardless of 
nanoMIPS support). I am going to integrate them via pull request next week 
separately, before the whole nanoMIPS series. Apart from fixing the issues, 
this will simplify nanoMIPS series, making it easier to understand/review.

For the rest of the patches, I am going to wait for v2.

Subject: [PATCH 00/35] nanoMIPS

This series of patches is implementing recently announced nanoMIPS on QEMU.
nanoMIPS is a variable length ISA containing 16, 32 and 48 bit wide
instructions. It is designed to be portable at assembly level with other MIPS
and microMIPS code, but contains a number of changes which enhance code density
and efficiency.
Most of nanoMIPS instructions exist in another MIPS ISAs. Therefore the large
portion of patches is decoding nanoMIPS opcodes.

More patches will be added later after this.
