[PATCH 0/9] s390/idle/vtime: Minor fixes and cleanups

Posted by Heiko Carstens 1 month, 1 week ago

Frederic Weisbecker's cputime accounting patch series motivated me to
finally have a deeper look at the s390 cputime accounting code. The result
are two bug fixes, which are not at all critical, and a couple of cleanups
and improvements.

Heiko Carstens (9):
  s390/idle: Fix cpu idle exit cpu time accounting
  s390/vtime: Fix virtual timer forwarding
  s390/idle: Add comment for non obvious code
  s390/idle: Slightly optimize idle time accounting
  s390/idle: Inline update_timer_idle()
  s390/irq/idle: Remove psw bits early
  s390/vtime: Use __this_cpu_read() / get rid of READ_ONCE()
  s390/vtime: Use lockdep_assert_irqs_disabled() instead of BUG_ON()
  s390/idle: Remove psw_idle() prototype
