These changes (along with corresponding QEMU and Linux kernel changes)
enable a guest to be booted using the x86/HVM direct boot ABI.
QEMU parses the uncompressed kernel binary passed to it via -kernel
to read the ELF Note which contains the address to be loaded. QEMU
then depends on qboot to populate the start_info struct needed by
the direct boot ABI and configure the guest e820 tables before
jumping to the loaded kernel entry.

The fseg and high memory malloc all use the up align
mode in do_alloc(),which will result in qboot hang
issue.The high memory use the down align mode and fseg
memory use the up align mode. With those changes,the
qemu can boot up the image with qboot.
