[Xen-devel] [PATCH] [IA64] Compilation fix to cpufreq stuff.

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Currently xen-unstable.hg is broken on ia64 and it should be fixed
by Yu's patch. However he is off this week, so I'm sending
the workaround patch.

[IA64] Compilation fix to cpufreq stuff.

This patch fixes the following compilation error by
defining stubs.
This patch is just band aid patch until those functions are implemented
later.

> .../xen/drivers/built_in.o: In function `set_px_pminfo':
> .../xen/drivers/cpufreq/cpufreq.c:226: undefined reference to `get_cpu_id'
> .../xen/drivers/cpufreq/cpufreq.c:268: undefined reference to 
> `xenpf_copy_px_states'
> .../xen/drivers/cpufreq/cpufreq.c:303: undefined reference to 
> `cpufreq_cpu_init'

This looks like it was introduce in one of these changes:
