Subject: [PATCH 2/2] KVM/PPC: Fix kvm_main.c build error for PPC KVM
Date: Thu,  2 Jul 2009 10:55:30 +0800	[thread overview]
Message-ID: <a3371dff010b57f832d47de0c15f4eb965041628.1246502441.git.yang.shi@windriver.com> (raw)

With the latest kernel building KVM for PPC, got integer overflow
error in kvm_main.c file. The root cause is that compiler consider
KVM_PAGES_PER_HPAGE as signed long type, however it should be
unsigned long type.

So, change it to unsigned long type in include/asm/kvm_host.h
