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.

config XZ_DEC_TEST tristate "XZ decompressor tester" default n depends on XZ_DEC help This allows passing .xz files to the in-kernel XZ decoder via a character special file. It calculates CRC32 of the decompressed data and writes diagnostics to the system log.
Unless you are developing the XZ decoder, you don't need this
and should say N.
