Linus Torvalds bb29b957ea Kbuild / Kconfig updates for 7.4
Kbuild:
 
 - Suppress compiler flags in debug info for external module builds
 
 - Use '-fmacro-prefix-map' in more places in the build
 
 - Merge initial set of changes from Lorenzo's speed up series, along
   with some fixes found through testing
 
   - Avoid allocating .modinfo in vmlinux
 
   - Speed up kallsyms by indexing symbols by token and outputting binary
     data to disk directly then including in assembly via .incbin
 
   - Don't sort $(NM) output when unnecessary
 
   - Only emit relocations on the final vmlinx link
 
   - Reimplement mksysmap in C
 
   - Move many cc-option and ld-option calls into the Kconfig stage to
     cache their results
 
   - Use pigz for gzip compression when available
 
 - Move gen_init_cpio and gen_initramfs.sh from usr/ to scripts/
 
 - Add a TOML configuration to scripts/container and update documentation
   accordingly
 
 - Add a generic, opt-in mechanism for checking that headers can compile
   standalone
 
 - Update machine function splitting argument for LLVM 24 rename in
   AutoFDO build
 
 - Miscellaneous minor clean ups, fixes, and hardening, mostly
   found/fixed via LLMs
 
 Kconfig:
 
 - Turn recursive ranges into an error
 
 - Fix savedefconfig for defaults that were adjusted for being out of
   range and revert a previously applied workaround
 
 - Improvements and hardening around integer and hexadecimal values
 
 - Emit a warning when selecting or implying a choice symbol, which has no
   effect
 
 - Emit a warning when KCONFIG_PROBABILITY is malformed
 
 - Introduce def_string / def_int / def_hex to mirror the existing
   def_bool / def_tristate to succinctly set a value and type at the same
   time.
 
 - Add cc-option-str and ld-option-str macros to act like Kbuild's
   cc-option and ld-option, returning the string when the option is
   supported, allowing many checks to be moved into Kconfig
 
 - Minor usability improvements to Kconfig tests
