Vasily Gorbik 5a2e1853d6 s390: avoid vmlinux segments overlap ... Currently .vmlinux.info section of uncompressed vmlinux elf image is included into the data segment and load address specified as 0. That extends data segment to address 0 and makes "text" and "data" segments overlap. Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000001000 0x0000000000100000 0x0000000000100000 0x0000000000ead03c 0x0000000000ead03c R E 0x1000 LOAD 0x0000000000eaf000 0x0000000000000000 0x0000000000000000 0x0000000001a13400 0x000000000233b520 RWE 0x1000 NOTE 0x0000000000eae000 0x0000000000fad000 0x0000000000fad000 0x000000000000003c 0x000000000000003c 0x4 Section to Segment mapping: Segment Sections... 00 .text .notes 01 .rodata __ksymtab __ksymtab_gpl __ksymtab_strings __param __modver .data..ro_after_init __ex_table .data __bug_table .init.text .exit.text .exit.data .altinstructions .altinstr_replacement .nospec_call_table .nospec_return_table .boot.data .init.data .data..percpu .bss .vmlinux.info 02 .notes Later when vmlinux.bin is produced from vmlinux, .vmlinux.info section is removed. But elf vmlinux file, even though it is not bootable anymore, used for debugging and loadable segments overlap should be avoided. Utilize special ":NONE" phdr specification to avoid adding .vmlinux.info into loadable data segment. Also set .vmlinux.info section type to INFO, which allows to get a not-loadable info CONTENTS section. Since minimal supported version of binutils 2.20 does not have --dump-section objcopy option, make .vmlinux.info section loadable during info.bin creation to get actual section contents.
