From: Herton R. Krzesinski <[email protected]> redhat: change compression flags for xz
The macro compression_flags is used in the compression of kernel modules. The default xz integrity check used is crc64. In the next change, we will switch to in-kernel decompression of modules. The problem is that it doesn't have support for the crc64 check, so we must manually switch to crc32. While at it, also add --lzma2=dict=1MiB which is also used by the kernel at scripts/Makefile.modinst and in general follows recommendation/dictionary sizes explained in the kernel documentation at Documentation/staging/xz.rst.
