time: Make VIRT_CPU_ACCOUNTING_GEN depend on GENERIC_CLOCKEVENTS
Browse files Browse the repository at this point in the history 
Moving the CONTEXT_TRACKING Kconfig option into kernel/time/Kconfig added
an implicit dependency on the surrounding GENERIC_CLOCKEVENTS option, but
this is not always enabled when it is possible to select
VIRT_CPU_ACCOUNTING_GEN:

WARNING: unmet direct dependencies detected for CONTEXT_TRACKING
  Depends on [n]: GENERIC_CLOCKEVENTS [=n]
  Selected by [y]:
  - VIRT_CPU_ACCOUNTING_GEN [=y] && <choice> && HAVE_CONTEXT_TRACKING [=y] && HAVE_VIRT_CPU_ACCOUNTING_GEN [=y]

Platforms without GENERIC_CLOCKEVENTS are rare enough so that corner case
can be just ignored. Make it a dependency for VIRT_CPU_ACCOUNTING_GEN to
simplify the configuration.
