Hello, This is re-send of the series. I didn't receive any comments on this but we found few minor things during in-house review which are incorporated. Changes to v1: - corrected kernel-doc for crash_setup_regs() - check return value of ioremap() in copy_oldmem_page() Changes to RFC version: - crash_setup_regs() uses Russell's suggestion for saving registers - copy_oldmem_page() code is changed to use ioremap() - there is no need for special 'mem=' parameters I've tested this on N900 and beagleboard. Thanks, Mw Mika Westerberg (8): arm: kdump: reserve memory for crashkernel arm: kdump: implement crash_setup_regs() arm: kdump: implement machine_crash_shutdown() arm: kdump: skip indirection page when crashing arm: kdump: implement copy_oldmem_page() arm: allow passing an ELF64 header to elf_check_arch() arm: kdump: add support for elfcorehdr= parameter arm: kdump: add CONFIG_CRASH_DUMP Kconfig option arch/arm/Kconfig | 12 ++++++ arch/arm/include/asm/elf.h | 4 +- arch/arm/include/asm/kexec.h | 22 +++++++++- arch/arm/kernel/Makefile | 1 + arch/arm/kernel/crash_dump.c | 60 +++++++++++++++++++++++++++++ arch/arm/kernel/elf.c | 6 ++- arch/arm/kernel/machine_kexec.c | 4 ++ arch/arm/kernel/relocate_kernel.S | 6 +++ arch/arm/kernel/setup.c | 76 +++++++++++++++++++++++++++++++++++++ 9 files changed, 184 insertions(+), 7 deletions(-) create mode 100644 arch/arm/kernel/crash_dump.c
