Subject: [PATCH v4 10/10] xen: add per-platform defaults for NR_CPUS
Date: Thu, 31 May 2018 14:48:37 -0700	[thread overview]
Message-ID: <1527803317-31750-10-git-send-email-sstabellini@kernel.org> (raw)
In-Reply-To: <alpine.DEB.2.10.1805311447570.23991@sstabellini-ThinkPad-X260>

Add specific per-platform defaults for NR_CPUS. Note that the order of
the defaults matter: they need to go first, otherwise the generic
defaults will be applied.

This is done so that Xen builds customized for a specific hardware
platform can have the right NR_CPUS number.
