Subject: arm64: dts: Reserve the memory used for secondary CPU release address
X-Git-Tag: v3.13-rc2~1^2~5
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=df503ba7f653c590b475ab80bde788edf5af70d5;p=~emulex%2Finfiniband.git

arm64: dts: Reserve the memory used for secondary CPU release address

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
started.
