[PATCH 15/21] linux: Compress the kernel, modules and firmware using Zstandard

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1559 bytes --]

Zstandard is an ideal compression algorithm with great performance for
this purpose. The kernel is still able to load firmware compressed using
XZ and ramdisks compressed with various other algorirthms.

Backported from IPFire 3.x as a3776d8aee67369dcff8ea091bc8b785dc2d6647.
