From: Christian Ruppert <christian.ruppert@xxxxxxxxxx>
Subject: init/Kconfig: fix option to disable kernel compression
Some architectures with self-decompressing kernel images did not compile
with commit 69f0554ec261fd68 ("init/Kconfig: add option to disable kernel
compression") because they don't provide a non-decompression mechanism for
uncompressed kernels.
Rectify this problem by allowing uncompressed kernels only for architectures
which explicitly state they support them.

No compression at all. The kernel is huge but the compression and
decompression times are zero.
