Alistair,

 Is there a specific Linux kernel feature required for RV32 support that 
version 5.4 has added worth mentioning in the change description?

 Otherwise OK.

 Also I suggest reordering this change and the next ahead of 15/19, so 
that the tree is consistent at the point RV32 builds are enabled with the 
removal of the trap from `sysdeps/riscv/preconfigure'.
