Clang emits the decompressor's strings in .rodata.str1.1 and also produces a .MIPS.abiflags section. GNU ld places such orphans next to similar sections, but ld.lld puts them after .bss: [ 5] .bss NOBITS 809246c0 5346b8 402010 [ 6] .MIPS.abiflags ... 80d266d0 9366d0 000018 [ 7] .rodata.str1.1 PROGBITS 80d266e8 9366e8 000164 This pulls the 4 MB of .bss (mostly the boot heap) into the file and leaves the strings beyond _end. For BCM47XX vmlinuz grows from 5.4 MB to 9.6 MB. Collect .rodata.* with .rodata, and discard .MIPS.abiflags and .gnu.attributes as arch/mips/kernel/vmlinux.lds.S does.
