Minimum `rustc` version required for powerpc is 1.95 as some critical features required for compiling rust code for kernel are not there. For example Stable inline asm support which got merged in 1.95.
Didn’t we decide on 1.85.0 with the asm_experimental_arch feature instead? And possibly on 64-bit 1.87.0 if it isn’t possible to disable altivec correctly there?
