The patch titled
parisc: set memory ranges in N_NORMAL_MEMORY when onlined
has been removed from the -mm tree. Its filename was
parisc-set-memory-ranges-in-n_normal_memory-when-onlined.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: parisc: set memory ranges in N_NORMAL_MEMORY when onlined
From: David Rientjes <rientjes@xxxxxxxxxx>
When a DISCONTIGMEM memory range is brought online as a NUMA node, it also
needs to have its bet set in N_NORMAL_MEMORY. This is necessary for
generic kernel code that utilizes N_NORMAL_MEMORY as a subset of N_ONLINE
for memory savings.
These types of hacks can hopefully be removed once DISCONTIGMEM is either
removed or abstracted away from CONFIG_NUMA.
Fixes a panic in the slub code which only initializes structures for
N_NORMAL_MEMORY to save memory:
