	## An ugly hack: we want kmods to be processed by find-debuginfo,
	## but it processes only files with executable permission set.
	## It is important now since, as of now, if debuginfo package
	## is enabled (and it is enabled), there's an RPM build error
	## as a result of lack of ether absence or emptiness of
	## debugsourcefiles.list (which is likely a bug in RPM, but it looks
	## like that there's no obvious fix and apparently no one have
	## any issues with this).
	## In order to minimise intrusiveness, usually (in Red Hat-built kmod
	## RPMs) *.ko files just have executable permission being set as a part
	## of %build section. There are two caveats with kmp, however:
	##  * We have no control over %build section itself (and it wasn't
	##    required previously)
	##  * Changing the criteria used in find-debuginfo.sh/brp-strip
	##    for selecting files that have to undergo debug section separation
	##    may introduce regression.
	## As a result, we insert additional hooks in __spec_install_post
	## (__brp_kmod_set_exec_bit in the beginning and
	## __brp_kmod_restore_perms in the end) that (temporarily) set
	## executable permission for *.ko files so find-debuginfo.sh will pick
	## them up.
	## Unfortunately, __spec_install_post's body is copied here since
	## we want that __debug_package macro expansion has been performed
	## lazily and  it looks like RPM has no ability to provide a body
	## of a macro verbatim.
