Subject: [PATCH] powerpc: Make KVM_GUEST default to n
Date: Fri, 5 Aug 2011 13:23:58 +1000	[thread overview]
Message-ID: <20110805132358.086648e5@kryten> (raw)


KVM_GUEST adds a 1 MB array to the kernel (kvm_tmp) which grew
my kernel enough to cause it to fail to boot.

Dynamically allocating or reducing the size of this array is a
good idea, but in the meantime I think it makes sense to make
KVM_GUEST default to n in order to minimise surprises.
