 # xzkern uses a big LZMA2 dictionary since it doesn't increase memory usage
 # of the kernel decompressor. A BCJ filter is used if it is available for
-# the target architecture. xzkern also appends uncompressed size of the data
-# using size_append. The .xz format has the size information available at
-# the end of the file too, but it's in more complex format and it's good to
-# avoid changing the part of the boot code that reads the uncompressed size.
