Merge branch 'liblockdep-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux into core/urgent

Pull liblockdep fixes from Sasha Levin:

 " 1. There was a build breakage caused by marking a function 'asmlinkage'
   in lockdep.h. Fix that by ignoring asmlinkage and visible annotations.

   2. Josh Boyer mentioned that Fedora would like to include liblockdep
   as a package, so we had to fix our versioning methods from being dumb
   and pointless to something actually usable. So now liblockdep.so tracks
   the kernel version which makes lives of distro folks much easier. "
