Subject: [PATCH] x86 idle: EXPORT_SYMBOL(default_idle, pm_idle) if
 CONFIG_APM_MODULE (only)

Commit 06ae40ce073daf233607a3c54a489f2c1e44683e ('x86 idle:
EXPORT_SYMBOL(default_idle, pm_idle) only when APM demands it') made
these exports dependent on CONFIG_APM_MODULE && CONFIG_APM_CPU_IDLE.
However, the apm module always needs these symbols.
CONFIG_APM_CPU_IDLE only controls whether it installs its CPU idle
handler by default.

Signed-off-by: Ben Hutchings <ben@...adent.org.uk>

This fixes a regression in 3.0-rc1 and should be applied in this cycle.

Ben.
