FOSS activity in August 2023

Updated the linux-5.10 package in buster and issued DLA-3512-1 for it.
Together with Aurelien Jarno, I investigated boot failures of Linux 5.10 and later versions on Debian's MIPS buildds, but I didn't find the root cause or any solution.
Reviewed and tested the kernel mitigations for the SRSO (CVE-2023-20569) issue in AMD CPUs, and added a critical missing patch to the backports.
Updated the linux (4.19) and linux-5.10 packages in buster, and the linux (5.10) package in bullseye, to include mitigations for GDS (CVE-2022-40982) on Intel processors and (5.10 only) SRSO on AMD. I issued DLA-3524-1 and DLA-3525-1 for buster.
Nattie and I hosted a 30th birthday party for Debian in Leuven.
Rebased and submitted my fixes for dahdi-linux.
Updated the linux master branch to upstream version 6.5-rc4 and uploaded to experimental.
Updated the backports of linux in bullseye-backports and bookworm-backports.
Updated jinja-vanish to be compatible with Jinja 3.0. I also wired up its test suite to autopkgtests and added a Salsa CI configuration to catch any future regressions more quickly.
