16GB hugepages may not be part of a memory region (firmware restriction). This
patch
modifies the walk_memory_resource callback fn to filter hugepages and add only

Hi,
we are a bit worried about putting this into the mainstream part of non real
time linux. There interrupts work perfectly fine, and it was a bit of a
challenge to get there for all cases / configurations / machines.
Could you try to enable these changes only for RT-Linux via a real-time
kconf
This patch fixes two weaknesses in send/receive packet handling which may
lead to kernel panics during DLPAR memory add operations.
