[PATCH 3.10 124/129] arm64: dts: Reserve the memory used for secondary CPU release address

From: Greg Kroah-Hartman
Date: Mon Jan 06 2014 - 18:01:53 EST

3.10-stable review patch. If anyone has any objections, please let me know.


From: Catalin Marinas <catalin.marinas@xxxxxxx>

commit df503ba7f653c590b475ab80bde788edf5af70d5 upstream.

With the spin-table SMP booting method, secondary CPUs poll a location
passed in the DT. The foundation-v8.dts file doesn't have this memory
reserved and there is a risk of Linux using it before secondary CPUs are
