Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:GPL-2.0-only

This restores the old behavior that existed before 2013-02-22, when
changes were made by 64dbfb444c150 ("decompressors: drop dependency on
CONFIG_EXPERT") and 5dc49c75a2 ("decompressors: make the default
XZ_DEC_* config match the selected architecture").Disabling the filters only makes sense on embedded systems.

Commit 5dc49c75a26b ("decompressors: make the default XZ_DEC_* config
match the selected architecture") addeddefault y if POWERPC
to lib/xz/Kconfig. But there is no Kconfig symbol POWERPC. The most
general Kconfig symbol for the powerpc architecture is PPC. So let's
use that.Signed-off-by: Paul Bolle

Change the defautl XZ_DEC_* config symbol to match the configured
architecture. It is perfectly legitimate to support multiple XZ BCJ
filters for different architectures (e.g.: to mount foreign squashfs/xz
compressed filesystems), it is however more natural not to select them all
by default, but only the one matching the configured architecture.Signed-off-by: Florian Fainelli

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar

In userspace, the .lzma format has become mostly a legacy file format that
got superseded by the .xz format. Similarly, LZMA Utils was superseded by
XZ Utils.These patches add support for XZ decompression into the kernel. Most of
the code is as is from XZ Embedded .
It was written for the Linux kernel but is usable in other projects too.Advantages of XZ over the current LZMA code in the kernel:
- Nice API that can be used by other kernel modules; it's
not limited to kernel, initramfs, and initrd decompression.
- Integrity check support (CRC32)
- BCJ filters improve compression of executable code on
certain architectures. These together with LZMA2 can
produce a few percent smaller kernel or Squashfs images
than plain LZMA without making the decompression slower.This patch: Add the main decompression code (xz_dec), testing module
(xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool,
and documentation. The xz_dec module is enough to have a usable XZ
decompressor e.g. for Squashfs.Signed-off-by: Lasse Collin
