   4 Subject: [PATCH] um: Fix build w/o CONFIG_PM_SLEEP
   5
   6 uml_pm_wake() is unconditionally called from the SIGUSR1 wakeup
   7 handler since that's in the userspace portion of UML, and thus
   8 a bit tricky to ifdef out. Since pm_system_wakeup() can always
   9 be called (but may be an empty inline), also simply always have
  10 uml_pm_wake() to fix the build.
