Seeing the volume of these and the amount of ground they touch, I'm now having second thoughts about rushing this into 6.11. Particularly with the header changes, I think it might be smart to let it cook in linux-next for a bit before sending it to Linus. $ git --no-pager diff --name-only linus/master arch/x86/entry/vdso/vma.c arch/x86/include/asm/pvclock.h arch/x86/include/asm/vdso/vsyscall.h drivers/char/random.c include/asm-generic/unaligned.h include/vdso/helpers.h include/vdso/unaligned.h lib/vdso/Makefile lib/vdso/getrandom.c tools/arch/x86/vdso tools/include/linux/linkage.h tools/testing/selftests/vDSO/Makefile tools/testing/selftests/vDSO/vdso_config.h tools/testing/selftests/vDSO/vdso_test_getrandom.c So I think what I'll do is, for 6.11-rc6, send in the real bug fixes, which right now amount to: - random: vDSO: reject unknown getrandom() flags - random: vDSO: don't use 64-bit atomics on 32-bit architectures $ git --no-pager diff --name-only linus/master..a90592ab7cad drivers/char/random.c lib/vdso/getrandom.c And then for the pending aarm64, ppc64(/32?), and loongarch enablement patches for 6.12, I'll just take those through my random.git tree, which have all of these build-system preliminaries. And then we'll obviously require acks from the maintainers of the archs for each of those arch enablement patches. If that sounds like an acceptable plan, you might want to mention in the cover letter that you're basing your arch-specific patches on https://git.kernel.org/pub/scm/linux/kernel/git/crng/random.git/ and want an ack from the arch maintainer, etc. Jason
