I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up

Anyone who wants to do copy to/from user from a kernel thread, needs use_mm (like what fs/aio has). Move that into mm/, to make reusing and exporting easier down the line, and make aio use it. Next intended user, besides aio, will be vhost-net. Acked-by: Andrea Arcangeli <aarcange at redhat.com> Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- fs/aio.c |

Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the long-term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in places where a RAM device was assumed to be present and allows some more objects to be

Hi, I have buit Xen (32 bit) with PAE and can start multiple Paraguests with 4 gig memory, but cannot launch a single VM with more than 4 gb memory. I would like to launch 1 VM with 30GB or so memory. Are there any config paramters like kernel,/inittrd that need to be changed. I have the ramdisk set to the initrd I used to boot xen with PAE. Thanks - padma

These helpers are only for use with kernel threads, and I will tie them more into the kthread infrastructure going forward. Also move the prototypes to kthread.h - mmu_context.h was a little weird to start with as it otherwise contains very low-level MM bits.

Thanks Ilia for the v2 review! Here is the v3 of this IOMMU support for GK20A series. Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove
