Subject: kvm: how big is type?

arch/x86/kvm/x86.c:3484:25: warning: cast truncates bits from constant value (100 becomes 0)
arch/x86/kvm/x86.c:3510:24: warning: cast truncates bits from constant value (100 becomes 0)

The problem:
		cseg_desc.type &= ~(1 << 8); //clear the B flag
		nseg_desc.type |= (1 << 8);

type is a 4-bit bitfield on x86....please look into this.

Harvey
