I'll try and build this, at least.
As for the futex support, I did notice that the Ingenic CPUs supposedly have
cpu_has_llsc defined as 1 in...
In the legacy kernel, there is no similar overriding for Ingenic CPUs, and
instead it seems that arch/mips/kernel/cpu-probe.c does some work testing the
processor identifier against known values and setting MIPS_CPU_LLSC
accordingly, this later being used in include/asm-mips/cpu-features.h to
So it is possible that LL/SC support is missing and that this flag might be
unset for better performance. But that is just an idea.
