This patchset is for adding efi runtime support on kexec kernel kernel patches see below thread: http://thread.gmane.org/gmane.linux.kernel.efi/2491 in kexec-tools, this patchset will do below: 1. retrieve efi_info from debugfs boot_params, and fill the x86 setup header 2. collect data efi runtime needed: /sys/firmware/efi/systab: fw_vendor, runtime, config_tables and smbios /sys/firmware/efi/efi-runtime-map/*, the phys-virt mappings in 1st kernel 3. assemble setup_data based on data get in 2) then pass it to 2nd kernel changelog v3->v4: update efi_info memmap to the saved runtime map instead of use 1st kernel untouched memmap. Tested on OVMF, dell laptop, lenovo laptop and HP workstation Dave Young (4): build fix: include x86-linux.h in x86-linux-setup.h Add function get_bootparam Add efi_info in x86 setup header Passing efi related data via setup_data include/x86/x86-linux.h | 3 +- kexec/arch/i386/crashdump-x86.c | 4 +- kexec/arch/i386/x86-linux-setup.c | 246 ++++++++++++++++++++++++++++++++++-- kexec/arch/i386/x86-linux-setup.h | 2 + kexec/arch/x86_64/kexec-bzImage64.c | 6 + 5 files changed, 248 insertions(+), 13 deletions(-) -- 1.8.3.1
