Impact: fix vmlinux from 2.6.30
from 2.6.30 (?) the new vmlinux with per_cpu and brk support will have more sections. Elf file type is EXEC (Executable file) Entry point 0x200000 There are 7 program headers, starting at offset 64 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000200000 0xffffffff80200000 0x0000000000200000 0x0000000000e46000 0x0000000000e46000 R E 200000 LOAD 0x0000000001046000 0xffffffff81046000 0x0000000001046000 0x00000000001406e0 0x00000000001406e0 RWE 200000 LOAD 0x0000000001200000 0xffffffffff600000 0x0000000001187000 0x0000000000000888 0x0000000000000888 RWE 200000 LOAD 0x0000000001388000 0xffffffff81188000 0x0000000001188000 0x000000000008a086 0x000000000008a086 RWE 200000 LOAD 0x0000000001600000 0x0000000000000000 0x0000000001213000 0x0000000000015e20 0x0000000000015e20 RWE 200000 LOAD 0x0000000001629000 0xffffffff81229000 0x0000000001229000 0x0000000000000000 0x0000000000208000 RWE 200000 NOTE 0x0000000000b3c7e8 0xffffffff80b3c7e8 0x0000000000b3c7e8 0x0000000000000024 0x0000000000000024 4 Section to Segment mapping: Segment Sections... 00 .text .notes __ex_table .rodata __bug_table .pci_fixup .builtin_fw __ksymtab __ksymtab_gpl __ksymtab_strings __init_rodata __param 01 .data .init.rodata .data.cacheline_aligned .data.read_mostly 02 .vsyscall_0 .vsyscall_fn .vsyscall_gtod_data .vsyscall_1 .vsyscall_2 .vgetcpu_mode .jiffies 03 .data.init_task .smp_locks .init.text .init.data .init.setup .initcall.init .con_initcall.init .x86_cpu_dev.init .altinstructions .altinstr_replacement .exit.text .init.ramfs 04 .data.percpu 05 .bss .brk 06 .notes So need to increase NR_SECTIONS. also fix one typo about phys address mask. Peter says: A similar fix was also implemented by Maciej Pijanka, so let's commit this now, eh. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Ronald G.
