David Gibson c594adad56 [PATCH] Dynamic hugepage addresses for ppc64 ... 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).
