[POWERPC] PS3: Add logical performance monitor driver support

	  be disabled on the kernel command line using "ps3flash=off", to

	  not allocate this fixed buffer.

config PS3_LPM

	tristate "PS3 Logical Performance Monitor support"

	depends on PPC_PS3

	help

	  Include support for the PS3 Logical Performance Monitor.

	  This support is required to use the logical performance monitor

	  of the PS3's LV1 hypervisor.

	  If you intend to use the advanced performance monitoring and

	  profiling support of the Cell processor with programs like

	  oprofile and perfmon2, then say Y or M, otherwise say N.
