Hi,
this is another step to make the memory hotplug more usable. The primary
goal of this patchset is to reduce memory overhead of the hot added

Physical memory hotadd has to allocate a memmap (struct page array) for
the newly added memory section. kmalloc is currantly used for those
allocations.
This has some disadvantages a) an existing memory is consumed for

Enabling and preparing clocks can be written quite naturally with
recursion. We start at some point in the tree and recurse up the
tree to find the oldest parent clk that needs to be enabled or
