Paulus, I think this is now a reasonable candidate for the post-2.6.13 queue. Relax address restrictions for hugepages on ppc64 Presently, 64-bit applications on ppc64 may only use hugepages in the address region from 1-1.5T. Furthermore, if hugepages are enabled in the kernel config, they may only use hugepages and never normal pages in this area. This patch relaxes this restriction, allowing any address to be used with hugepages, but with a 1TB granularity. That is if you map a hugepage anywhere in the region 1TB-2TB, that entire area will be reserved exclusively for hugepages for the remainder of the process's lifetime. This works analagously to hugepages in 32-bit applications, where hugepages can be mapped anywhere, but with 256MB (mmu segment) granularity. This patch applies on top of the four level pagetable patch (http://patchwork.ozlabs.org/linuxppc64/patch?id=1936).

When we leave sigsuspend() directly into a signal handler, we don't want to go via the normal syscall exit path -- it'll corrupt r4 and r5 which are supposed to be giving information to the signal handler, and it'll give us one more single-step SIGTRAP than we need if single-stepping is in operation. However, we _should_ be calling audit_syscall_exit(), which would normally get invoked in that patch. It's not wonderfully pretty, but I suspect the best answer is just to call it directly...

This patch removes some unused bits from HvCall.h and some unneeded #includes from other files. Also includes ItLpQueue.h in paca.h in preference to a stub declaration of struct ItLpQueue.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
