around the fallout from the new CONFIG_OBJTOOL_WERROR=y feature,
which, despite its default-off nature, increased the profile/impact
of objtool warnings:
- Improve error handling and the presentation of warnings/errors.
- Revert the new summary warning line that some test-bot tools
interpreted as new regressions.
- Fix a number of objtool warnings in various drivers, core kernel
code and architecture code. About half of them are potential
problems related to out-of-bounds accesses or potential undefined
behavior, the other half are additional objtool annotations.
- Update objtool to latest (known) compiler quirks and
objtool bugs triggered by compiler code generation
- Misc fixes
