target-ppc: Confirm That .bss Pages Are Valid
The existing code does a check to ensure that a .bss region is properly mmap'd. When additional mmap is required, the (guest) pages are also validated. However, this code has a bug: when host page size is larger than target page size, it is possible for the .bss pages to already be (host) mapped but the guest .bss pages may not be valid. The check to mmap additional space is separated from the flagging of the target (guest) pages, thus ensuring that both aspects are done properly.
