XZ Embedded, the upstream project, switched from public domain to the
BSD Zero Clause License (0BSD). Now matching SPDX license identifiers
can be added.
Documentation was revised. Fix syntax errors in kernel-doc comments in
<linux/xz.h>. The xz_dec API docs from <linux/xz.h> are now included in
Documentation/staging/xz.rst.
The new ARM64 and RISC-V filters can be used for kernel decompression
if CONFIG_EFI_ZBOOT=y. The filters can be used by Squashfs too.
(Userspace Squashfs-tools already had the ARM64 filter support committed
but it was reverted due to backdoor fears. I try to get ARM64 and RISC-V
filter support added to Squashfs-tools somewhat soon.)
Account for the default threading change made in the xz command line
tool version 5.6.0. Tweak kernel compression options for archs that
support XZ compressed kernel.
v2:
- Omit Jia Tan from MAINTAINERS and commit messages.
- Don't change home page URLs as the home pages were moved back
to their old locations.
- Add xz_dec (<linux/xz.h>) kernel-doc fixes and improvements.
- arm64: Add the make target Image.xz for CONFIG_EFI_ZBOOT=n.
- riscv: Add the make target Image.xz and set HAVE_KERNEL_XZ
in Kconfig like it is done with other compressors for
CONFIG_EFI_ZBOOT=n.
