We have two implementations of kernel_tree_alloc() - one in fdt.c and
another in pdt.c.

$ grep kernel_tree_alloc *
fdt.c:static void *kernel_tree_alloc(u64 size, u64 align)
fdt.c:  __unflatten_device_tree(device_tree, mynodes, &kernel_tree_alloc);
pdt.c:static void * __init kernel_tree_alloc(u64 size, u64 align)
pdt.c:  of_alias_scan(kernel_tree_alloc);

The version in fdt.c is using kzalloc() whereas the version in pdt.c
uses prom_early_alloc().

And of_fdt_unflatten_tree() uses the version in fdt.c - so the patch is OK.

It is confusing that they have the same name - but I did nto fix that.
And I forgot about this detail when I wrote the changelog.
