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 Signed-off-by: Yang Shi <yang.shi@windriver.com> --- arch/powerpc/include/asm/kvm_host.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
