Hi Geoff, Does arm64 has secureboot? If yes, then it might make sense to enable the new syscall kexec_file_load() on arm64 instead of trying to make old syscall work first.

It will save efforts for efi support as well, for the in-kernel loader we do not necessary to save the efi physical addresses or runtime ranges to sysfs and passing them to 2nd kernel, we can just copy them in kernel. Thanks Dave

Yes, arm64 should support secureboot, but I have not looked into it. When do you expect syscall kexec_file_load to get merged? I won't wait until then to push my current kexec work. -Geoff

Hi, Here are a few minor fixups and enhancements for kexec support. Patch 3 and 4 that add preprocessor macros for the kimage list flags are ones that I use in the arm64 kexec support I am working on, so it would be nice for those to go in. Please consider. -Geoff The following changes since commit 7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9: Linux 3.17-rc1 (2014-08-16 10:40:26 -0600) are available in the git repository at: git://git.linaro.org/people/geoff.levand/linux-kexec.git for-kexec for you to fetch changes up to dc3c63e69815e00dce5454bd50e2991e9ea33f64: powerpc/kexec: Use global IND_FLAGS macro (2014-08-22 11:15:18 -0700) ---------------------------------------------------------------- Geoff Levand (5): kexec: Fix make headers_check kexec: Simplify conditional kexec: Add bit definitions for kimage entry flags kexec: Add IND_FLAGS macro powerpc/kexec: Use global IND_FLAGS macro arch/powerpc/kernel/machine_kexec_64.c | 2 -- include/linux/kexec.h | 20 ++++++++++++++++---- include/uapi/linux/kexec.h | 6 ------ kernel/kexec.c | 17 ++++++++++------- 4 files changed, 26 insertions(+), 19 deletions(-)
