The patch results in fewer output sections, and some data being reordered, but should have no functional impact. Also, note that this patch moves some data (namely, init_task and cacheline-aligned) inside [_sdata,_edata]. Because frv already builds using -ffunction-sections -fdata-sections, we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not currently include the required .bss.* and .data.* sections.
