Hypervisors typically intercept CPUID leaves in the range 0x40000000 to 0x400000ff, with leaf 0x40000000 returning the maximum supported function within this range in register %eax. iPXE currently masks off bit 30 from the requested CPUID leaf when checking to see if a function is supported, which causes this check to read from leaf 0x00000000 instead of 0x40000000. Fix by including bit 30 within the mask. Signed-off-by: Michael Brown <mcb30@ipxe.org>
