Do you think the kmap() patches are still causing issues? sparc32 UP and microblaze work for me with next-20200603, but I didn't test other architectures. > For my part, all I can say is that -next is in pretty bad shape right now. > The summary of my tests says: > > Build results: > total: 151 pass: 130 fail: 21 > Qemu test results: > total: 430 pass: 375 fail: 55 > > sparc32 smp images in next-20200603 still crash for me with a spinlock > recursion.
