In order to extract NUMA information from the device tree, we need to
have the tree in its unflattened form.
Move the call to unflatten_device_tree() into paging_init(). This
puts it before the call to bootmem_init(), which is where the NUMA
information is extracted.
Can't you just move up unflatten_device_tree in setup_arch rather than
hiding in paging_init?
No.
It must come *after* map_mem() and *before* bootmem_init(), both of
which are done within paging_init().
One option would be to split the things in paging_init() into two
functions, and then do:
.
.
.
paging_init_first_part();
if (acpi_disabled)
unflatten_device_tree();
paging_init_second_part();
.
.
.
