[PATCH] kvm: ppc: update KVM config options in ppc44x_defconfig

KVM host support was recently enabled in ppc44x_defconfig, but since then the config option was renamed. Update ppc44x_defconfig to match. Also, KVM guests aren't very interesting without networking, so enable CONFIG_TUN and CONFIG_BRIDGE. Signed-off-by: Hollis Blanchard <[EMAIL PROTECTED]> ---

[PATCH 3 of 3] kvm: ppc: fix userspace mapping invalidation on context switch

We used to defer invalidating userspace TLB entries until jumping out of the kernel. This was causing MMU weirdness most easily triggered by using a pipe in the guest, e.g. "dmesg | tail". I believe the problem was that after the guest kernel changed the PID (part of context switch), the old proces

[PATCH 2 of 3] kvm: ppc: use prefetchable mappings for guest memory

Bare metal Linux on 440 can "overmap" RAM in the kernel linear map, so that it can use large (256MB) mappings even if memory isn't a multiple of 256MB. To prevent the hardware prefetcher from loading from an invalid physical address through that mapping, it's marked Guarded. However, KVM must ensu

[PATCH 0 of 3] some kernel fixes for PPC440 KVM

Hi Avi, these patches fix some minor PowerPC kernel issues, including a nasty MMU bug that was exposed by 64K pages on the host, but could also affect 4K pages. Please apply. -Hollis -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to [EMAIL PROTECTED
