  1. [contrib][linux] Fix build with CONFIG_WERROR 

    Linux 5.15 introduces a new Kconfig option, CONFIG_WERROR, which
forces -Werror for the entire kernel.
Current in-kernel ZSTD implementation uses functions deprecated
in 1.5.0, and thus fails on -Wdeprecated-declarations.
Turn this particular error into warning to be able to build the
kernel with CONFIG_WERROR. I'm not disabling them completely to
make sure they'll be visible and [hopefully] fixed sooner or later.

  2. [contrib][linux] Add huf_decompress_amd64.o target to Makefile 

    Commit a5f2c45 ("Huffman ASM") added a new ASM source file,
but it wasn't added to the kernel Makefile despite that it received
support for Huffman ASM according to the internal definitions. This
leads to undefined references, as huf_decompress.o now calls those
ASM functions.
Add it to the list of sources when building inside the kernel tree.
Kbuild can handle .S files just fine, so none additional rules
needed.

Fixes: a5f2c45 ("Huffman ASM")

  3. [contrib][linux] Add contrib/linux-kernel/linux to .gitignore 

    The mentioned path is being created/used by the 'import' rule for
generating source files for Linux kernel.
