They are now against Linux-3.3, and I plan for them to go upstream for Linux-3.5. I'll rebase them again once a few 3.4-rc's are out. This work needs to be tested more, especially needed is testing of the passing of data in the highmem region. Please test and report. Nathan, these patches fix the well known node names, so it would be best if you could add support to test for pre-allocated highmem regions in your FreeBSD port. -Geoff The following changes since commit c16fa4f2ad19908a47c63d8fa436a1178438c7e7: Linux 3.3 (2012-03-18 16:15:34 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux.git for-powerpc for you to fetch changes up to aab56ec9e2989fc9960cae3927534cb81173dff5: powerpc/ps3: Refresh ps3_defconfig (2012-03-31 18:25:20 -0700) ---------------------------------------------------------------- Andre Heider (3): powerpc/ps3: Add highmem repository read routines powerpc/ps3: Use highmem region from repository powerpc/ps3: Remove MEMORY_HOTPLUG requirement Geoff Levand (5): powerpc/ps3: Correct lv1 repository routine names powerpc/ps3: Add PS3 repository write support powerpc/ps3: Add highmem repository write routines powerpc/ps3: Minor Kconfig cleanup powerpc/ps3: Refresh ps3_defconfig Hector Martin (1): powerpc/ps3: Add highmem region memory early arch/powerpc/configs/ps3_defconfig | 8 +- arch/powerpc/include/asm/lv1call.h | 4 +- arch/powerpc/platforms/ps3/Kconfig | 22 +++- arch/powerpc/platforms/ps3/mm.c | 77 ++++++------ arch/powerpc/platforms/ps3/platform.h | 16 +++ arch/powerpc/platforms/ps3/repository.c | 198 +++++++++++++++++++++++++++++++ 6 files changed, 277 insertions(+), 48 deletions(-)
