Pull objtool fixes from Ingo Molnar:
 "These are objtool fixes and updates by Josh Poimboeuf, centered 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"
