When compiling the kernel with debug information i got the following error: hppa-linux-gnu-ld: section .text LMA [0000000000e78000,0000000000e7b41f] overlaps section .rodata.compressed LMA [00000000000e0078,00000000015ad43d] make[3]: *** [/home/svens/parisc-linux/src/arch/parisc/boot/compressed/Makefile:28: arch/parisc/boot/compressed/vmlinux] Error 1 make[2]: *** [/home/svens/parisc-linux/src/arch/parisc/boot/Makefile:17: arch/parisc/boot/compressed/vmlinux] Error 2 make[2]: Target 'arch/parisc/boot/bzImage' not remade because of errors. While this might also be fixed by adjusting the linker script, i think we should strip the debug information when generating the compressed image. This reduces the size of vmlinuz/lifimage from ~69MB to 6.6MB when full debug information is enabled.
