[PATCH v4 00/13] Add build ID to stacktraces

This series adds the kernel's build ID[1] to the stacktrace header printed in oops messages, warnings, etc. and the build ID for any module that appears in the stacktrace after the module name. The goal is to make the stacktrace more self-contained and descriptive by including the relevant build ID

[PATCH v4 13/13] kdump: Use vmlinux_build_id to simplify

We can use the vmlinux_build_id array here now instead of open coding it. This mostly consolidates code. Cc: Jiri Olsa Cc: Alexei Starovoitov Cc: Jessica Yu Cc: Evan Green Cc: Hsin-Yi Wang Cc: Dave Young Cc: Baoquan He Cc: Vivek Goyal Cc: Signed-off-by: Stephen Boyd --- include/linux/cr

[PATCH v4 03/13] buildid: Stash away kernels build ID on init

Parse the kernel's build ID at initialization so that other code can print a hex format string representation of the running kernel's build ID. This will be used in the kdump and dump_stack code so that developers can easily locate the vmlinux debug symbols for a crash/stacktrace. Cc: Jiri Olsa C

[CFT][PATCH] kexec: Remove the error prone kernel_version function

During kexec there are two kernel versions at play. The version of the running kernel and the version of the kernel that will be booted. On powerpc it appears people have been using the version of the running kernel to attempt to detect properties of the kernel to be booted which is just wrong.

[PATCH v2 1/1] kernel.h: Split out panic and oops helpers

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h
