It seems that lz4 supports legacy format with the same option as lz4c
does. Just looking at the first few bytes of lz4 compressed image, we
can see whether it is new format or not.
It shows new format magic number without this patch. New format magic
number is 0x184d2204.

Documentation/x86/boot.txt is updated to list the LZ4 magic number.
This LZ4 magic number is used for the new compression format.

The size of de/compress buffer is small enough to use kmalloc.
Allocating it with kmalloc rather than vmalloc is preferred.
This patch depends on my previous patch, “btrfs: fix decompress buffer size”.
v2: Using vmalloc for "workspace->mem" due to the size limit.

It is usually accepted that code should explain itself.
The max size of string is 1025(512*2 + 1) bytes so there is
no point to add one more byte for string allocation.
This patch is intended to fix incorrect size for string allocation
and make code more readable.
