Allow action caller to skip building pahole by passing 'none' as the target revision. See: https://lore.kernel.org/dwarves/8f5711430e4f9bb02fd06d3a5b00d46d8643fea1@linux.dev/ Signed-off-by: Ihor Solodrai <ihor.solodrai@linux.dev>

Cross compilation is broken due to apt packages conflicts. Switch to native builds for now. See: libbpf/ci#179 Signed-off-by: Ihor Solodrai <ihor.solodrai@linux.dev>

BPF CI got broken due to apt errors when installing cross compilers: * https://github.com/kernel-patches/bpf/actions/runs/14519065074/job/40735249827 dpkg --add-architecture now breaks apt config. Looks like there were changes in Ubuntu that require migrating to deb822 [1][2] format of apt package lists. In our case not only target arch repos need to be added, but also default /etc/apt/sources.list.d/ubuntu.sources needs to be modified. The host architecture has to be whitelisted, otherwise apt attempts fetching target arch packages from archive and security, and they are not there. Another issue was with libelf-dev:s390x dependencies. Current linux-libc-dev breaks linux-libc-dev:s390x, and unfortunately we need both for a proper cross-compilation build. Using aptituide I found that downgrading linux-libc-dev:amd64 resolves this conflict.

Apparently, downgrade of linux-libc-dev:amd64 helps: https://github.com/kernel-patches/vmtest/actions/runs/14520463948/job/40756555954 Merging this in. |
