Now we have limit kdump reserved under 896M, because kexec has the limitation. and also bzImage need to stay under 4g. kernel parts changes could be found at: git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-boot here patches are for kexec tools to load bzImage and ramdisk high acccording to new added boot header fields. -v2: remove mem64-min/mem64-max add purgartory changes from Eric, that make it relocatable put command line above 4g. Eric W. Biederman (1): kexec, x86: Make x64_64 purgatory relocatable above 4G Yinghai Lu (5): kexec, x86: add boot header member for version 2.12 kexec: don't die during buffer finding kexec, x86: put ramdisk high for 64bit bzImage kexec, x86: set ext_cmd_line_ptr when boot_param is put high kexec, x86_64: put 64bit bzImage high include/x86/x86-linux.h | 22 ++- kexec/arch/i386/x86-linux-setup.c | 40 +++- kexec/arch/x86_64/Makefile | 1 + kexec/arch/x86_64/kexec-bzImage64.c | 316 ++++++++++++++++++++++++++++++++ kexec/arch/x86_64/kexec-x86_64.c | 1 + kexec/arch/x86_64/kexec-x86_64.h | 5 + kexec/kexec.c | 7 +- purgatory/arch/i386/entry32-16-debug.S | 22 ++- purgatory/arch/i386/entry32-16.S | 22 ++- purgatory/arch/x86_64/Makefile | 4 +- purgatory/arch/x86_64/entry64-32.S | 68 +++++-- purgatory/arch/x86_64/entry64.S | 5 +- purgatory/arch/x86_64/setup-x86_64.S | 4 +- 13 files changed, 458 insertions(+), 59 deletions(-) create mode 100644 kexec/arch/x86_64/kexec-bzImage64.c -- 1.7.7
