@jarkko Nice! Might have to poke at it for ARM32 as well.

@arj ARM support can be added but not in the scope of my patch set. The priority is to implement it so that arch support can be gradually added.

Post this work ARM support could be added by:

  1. Implement alloc_execmem().
  2. Implement free_execmem().
  3. Edit appropriate arch Makefile.
  4. Set HAVE_ALLOC_EXECMEM in appropriate Kconfig.

@jarkko Ah, I didn't intend for you to interpret that as me asking you to add ARM support. Rather, your series is something I might end up experimenting with wrt ARM 🙂

@arj OK, cool, just giving evidence that there's no bottleneck to add more support, only four relatively simple steps :-)
