cpufreq/ppc: Add missing #include <asm/smp.h>
If CONFIG_SMP=n, <linux/smp.h> does not include <asm/smp.h>, causing: drivers/cpufreq/ppc-corenet-cpufreq.c: In function 'corenet_cpufreq_cpu_init': drivers/cpufreq/ppc-corenet-cpufreq.c:173:3: error: implicit declaration of function 'get_hard_smp_processor_id' [-Werror=implicit-funcuresh E. Warrier" <warrier@linux.vnet.ibm.com> X-Patchwork-Id: 443703 Message-Id: <54EE5989.7010800@linux.vnet.ibm.com> To: linuxppc-dev@ozlabs.org Date: Wed, 25 Feb 2015 17:23:53 -0600 Export __spin_yield so that the arch_spin_unlock() function can be invoked from a module. This will be required for modules where we want to take a lock that is also is acquired in hypervisor real mode. Because we want to avoid running any lockdep code (which may not be safe in real mode), this lock needs to be an arch_spinlock_t instead of a normal spinlock.
