Folks want to keep in mind that we run our kernel on MIPS, so our config
will be like a foreign virus to their build.  Won't work at all.

I don't think our config will be useful to them anyway...they should
start with the config they were using for 2.6.31, sync up the git
repository to 2.6.32.8 and just type 'make'.  The Kbuild system will
prompt them for any differences in the config that need to be resolved,
but likely there will be few that are relevant to LSI.

Here are some that we probably do want to turn on.  namespaces might
prove to be very useful as a VM replacement ~:^)


CONFIG_NAMESPACES=y
CONFIG_UTS_NS=y
CONFIG_IPC_NS=y
CONFIG_USER_NS=y
CONFIG_PID_NS=y
CONFIG_NET_NS=y

And of course

CONFIG_KSM=y

Does Xen want CONFIG_PARAVIRT_GUEST set for the VM kernels?  I don't
know.

Hope that helps,

a
