+ *
+ *   Warning: only use if a hole exists for _all_ arches.  Use pahole to verify.
+ *
+ * RH_KABI_FILL_HOLE
+ *   Simple macro for filling a hole in a struct.
+ *
+ * RH_KABI_RENAME
+ *   Simple macro for renaming an element without changing its type.  This
+ *   macro can be used in bitfields, for example.
+ *
+ *   NOTE: does not include the final ';'
+ *
+ * RH_KABI_REPLACE
+ *   Simple replacement of _orig with a union of _orig and _new.
+ *
+ *   The RH_KABI_REPLACE* macros attempt to add the ability to use the '_new'
+ *   element while preserving size alignment with the '_orig' element.
+ *
+ *   The #ifdef __GENKSYMS__ preserves the kABI agreement, while the anonymous
+ *   union structure preserves the size alignment (assuming the '_new' element
+ *   is not bigger than the '_orig' element).
+ *
+ * RH_KABI_REPLACE_UNSAFE
+ *   Unsafe version of RH_KABI_REPLACE.  Only use for typedefs.
+ *
+ * RH_KABI_FORCE_CHANGE
+ *   Force change of the symbol checksum.  The argument of the macro is a
+ *   version for cases we need to do this more than once.
+ *
+ *   This macro does the opposite: it changes the symbol checksum without
+ *   actually changing anything about the exported symbol.  It is useful for
+ *   symbols that are not whitelisted, we're changing them in an
+ *   incompatible way and want to prevent 3rd party modules to silently
+ *   corrupt memory.  Instead, by changing the symbol checksum, such modules
+ *   won't be loaded by the kernel.  This macro should only be used as a
+ *   last resort when all other KABI workarounds have failed.
+ *
+ * NOTE
+ *   Don't use ';' after these macros as it messes up the kABI checker by
+ *   changing what the resulting token string looks like.  Instead let this
+ *   macro add the ';' so it can be properly hidden from the kABI checker
+ *   (mainly for RH_KABI_EXTEND, but applied to all macros for uniformity).

Subject: [PATCH] Revert "cpupower: Bump soname version"

In preperation to bring kernel-tools back into the kernel package, this
needs to be reverted for F39 and F38. The actual change to justify the
soname bump were years ago, so let's leave userspace be and pick this up
in F40.

This reverts commit d7de5d8e403a1293e10f8f59a1f2db320232c831.
