Here's v3 of the OpenRISC architecture patch series. The major changes since version 2 are: i) cleanup of the ptrace code I've removed the single stepping code for now as I want to clean that up separately. Will resubmit that in 3.2. Have implemented exporting of thread state to userspace via the GETREGSET mechanism. This allows us to keep the pt_regs structure opaque and allows us to freely change the layout of the registers on the stack, which is something that we will want to do in order to get better cache behaviour. ii) rewrite of dma_alloc_consistent iii) clean up device tree code in response to feedback for the v2 patch set We only have a single example DTS file in the tree now, for the simulator, that goes along with the defconfig file. Aside from those three things, there are mostly cleanups coming from code review and from checkpatch. This tree should now be ready for inclusion in 3.1, but any feedback that lets us be that much better is of course appreciated. The code is available in the 'for-upstream' branch of the git repo at: git://openrisc.net/jonas/linux Note that there are 4 patches at the base of the branch changing asm-generic behaviour and reviewed separately. Note also, that the code in the branch depends on the devicetree/next branch and one patch from Rusty's patch set for 3.1.
