+ * RH_KABI_CONST
+ *   Adds a new const modifier to a function parameter preserving the old
+ *   checksum.
+ *
+ * RH_KABI_DEPRECATE
+ *   Mark the element as deprecated and make it unusable by modules while
+ *   preserving kABI checksums.
+ *
+ * RH_KABI_DEPRECATE_FN
+ *   Mark the function pointer as deprecated and make it unusable by modules
+ *   while preserving kABI checksums.
+ *
+ * RH_KABI_EXTEND
+ *   Simple macro for adding a new element to a struct.
+ *
+ * RH_KABI_EXTEND_WITH_SIZE
+ *   Adds a new element (usually a struct) to a struct and reserves extra
+ *   space for the new element.  The provided 'size' is the total space to
+ *   be added in longs (i.e. it's 8 * 'size' bytes), including the size of
+ *   the added element.  It is automatically checked that the new element
+ *   does not overflow the reserved space, now nor in the future. However,
+ *   no attempt is done to check the content of the added element (struct)
+ *   for kABI conformance - kABI checking inside the added element is
+ *   effectively switched off.
+ *   For any struct being added by RH_KABI_EXTEND_WITH_SIZE, it is
+ *   recommended its content to be documented as not covered by kABI
+ *   guarantee.
+ *
+ * RH_KABI_FILL_HOLE
+ *   Simple macro for filling a hole in a struct.
+ *
+ *   Warning: only use if a hole exists for _all_ arches.  Use pahole to verify.
+ *
+ * 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.
+ *
+ * RH_KABI_EXCLUDE
+ *   !!! WARNING: DANGEROUS, DO NOT USE unless you are aware of all the !!!
+ *   !!! implications. This should be used ONLY EXCEPTIONALLY and only  !!!
+ *   !!! under specific circumstances. Very likely, this macro does not !!!
+ *   !!! do what you expect it to do. Note that any usage of this macro !!!
+ *   !!! MUST be paired with a RH_KABI_FORCE_CHANGE annotation of       !!!
+ *   !!! a suitable symbol (or an equivalent safeguard) and the commit  !!!
+ *   !!! log MUST explain why the chosen solution is appropriate.       !!!
+ *
+ *   Exclude the element from checksum generation.  Any such element is
+ *   considered not to be part of the kABI whitelist and may be changed at
+ *   will.  Note however that it's the responsibility of the developer
+ *   changing the element to ensure 3rd party drivers using this element
+ *   won't panic, for example by not allowing them to be loaded.  That can
+ *   be achieved by changing another, non-whitelisted symbol they use,
+ *   either by nature of the change or by using RH_KABI_FORCE_CHANGE.
+ *
+ *   Also note that any change to the element must preserve its size. Change
+ *   of the size is not allowed and would constitute a silent kABI breakage.
+ *   Beware that the RH_KABI_EXCLUDE macro does not do any size checks.
+ *
+ * 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).
