Revision cec84e7547d3f95b3fa4ded1618cb43d5d98a76a authored by Linus Torvalds on 01 July 2022, 18:19:14 UTC, committed by Linus Torvalds on 01 July 2022, 18:19:14 UTC 
Merge tag 's390-5.19-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
 
Pull s390 fixes from Alexander Gordeev:

 - Fix purgatory build process so bin2c tool does not get built
   unnecessarily and the Makefile is more consistent with other
   architectures.

 - Return earlier simple design of arch_get_random_seed_long|int() and
   arch_get_random_long|int() callbacks as result of changes in generic
   RNG code.

 - Fix minor comment typos and spelling mistakes.
