There are many cases that Semiconductor is misspelled. The patch
fix these typos.

I noticed a couple of function prototypes for functions that
no longer exist. Remove them.

Most of setup.h should not be exported to userspace, so move it
back. All we are left with is the asm-generic include to pick
up the COMMAND_LINE_SIZE define.

When a memory is added, we update zone's and pgdat's start_pfn and
spanned_pages in the function __add_zone(). So we should revert them
when the memory is removed.
The patch adds a new function __remove_zone() to do this.

We call hotadd_new_pgdat() to allocate memory to store node_data. So we
should free it when removing a node.

Hi,
Please correct me if I'm wrong, but I thought that one of the reasons to
bring a board to mainline is that if someone breaks it he/she also fixes
it (at least this is what I tell to the attendees of my trainings).
... but maybe that's not always the case ...

All pages of virtual mapping in removed memory cannot be freed, since some pages
used as PGD/PUD includes not only removed memory but also other memory. So the
patch checks whether page can be freed or not.
How to check whether page can be freed or not?

From: Yasuaki Ishimatsu
For removing memmap region of sparse-vmemmap which is allocated bootmem,
memmap region of sparse-vmemmap needs to be registered by get_page_bootmem().
So the patch searches pages of virtual mapping and registers the pages by
get_page_bootmem().
Note: register_page_bootmem
For hot removing memory, we sholud remove page table about the memory.
So the patch searches a page table about the removed memory, and clear
page table.

This patch introduces a new function try_offline_node() to
remove sysfs file of node when all memory sections of this

not removed, this function does nothing.

We remove the memory like this:
1. lock memory hotplug
2. offline a memory block
3. unlock memory hotplug
4. repeat 1-3 to offline all memory blocks
5. lock memory hotplug
6. remove memory(TODO)
7. unlock memory hotplug
All memory blocks must be offlined before removing m
For removing memory, we need to remove page table. But it depends
on architecture. So the patch introduce arch_remove_memory() for
removing page table. Now it only calls __remove_pages().
Note: __remove_pages() for some archtecuture is not implemented

When (hot)adding memory into system, /sys/firmware/memmap/X/{end, start, type}

memory can't be offlined when CONFIG_MEMCG is selected.
For example: there is a memory device on node 1. The address range

and memory11 under the directory /sys/devices/system/memory/.
If CONFIG_MEMCG is selected, we will a

Currently __remove_section for SPARSEMEM_VMEMMAP does nothing. But even if
we use SPARSEMEM_VMEMMAP, we can unregister the memory_section.
So the patch add unregister_memory_section() into __remove_section().
