Subject: [PATCH] arm: zynq: platsmp: Remove CPU presence check
Date: Thu, 31 Oct 2013 10:37:09 -0700 [thread overview]
Message-ID: <1383241029-32018-1-git-send-email-soren.brinkmann@xilinx.com> (raw)
In-Reply-To: <20131031161739.GE16735@n2100.arm.linux.org.uk>
The generic code already checks that the CPU being requested is legal if
the cpu possible/present masks are set correctly.

As per Russel's suggestion, consider this alternative for 1/6.
