Subject: [PATCH v2 RESEND 0/5] sched/vtime: vtime.h headers cleanup

Hi All,

There are no changes since the last post, just a re-send.

v2:

- patch 4: commit message reworded (Heiko)
- patch 5: vtime.h is removed from Kbuild scripts (PowerPC only) (Heiko)

v1:

Please find a small cleanup to vtime_task_switch() wiring.
I split it into smaller patches to allow separate PowerPC
vs s390 reviews. Otherwise patches 2+3 and 4+5 could have
been merged.

I tested it on s390 and compile-tested it on 32- and 64-bit
PowerPC and few other major architectures only, but it is
only of concern for CONFIG_VIRT_CPU_ACCOUNTING_NATIVE-capable
ones (AFAICT).

Thanks!

Alexander Gordeev (5):
  sched/vtime: remove confusing arch_vtime_task_switch() declaration
  sched/vtime: get rid of generic vtime_task_switch() implementation
  s390/vtime: remove unused __ARCH_HAS_VTIME_TASK_SWITCH leftover
  s390/irq,nmi: include <asm/vtime.h> header directly
  sched/vtime: do not include <asm/vtime.h> header
