  Log Message:
  -----------
  kvm-all: exit in case max vcpus exceeded

Rather than fall back to TCG (so the user has to discover
whats happening, in case of no access to qemu stdout/stderr).

  file_ram_alloc: unify mem-path,mem-prealloc error handling

-mem-prealloc asks to preallocate memory residing on -mem-path path.

Currently QEMU exits in case:

- Memory file has been created but allocation via explicit write
fails.

And it fallbacks to malloc in case:
- Querying huge page size fails.
- Lack of sync MMU support.
- Open fails.
- mmap fails.

Have the same behaviour for all cases: fail in case -mem-path and
-mem-prealloc are specified for regions where the requested size is
suitable for hugepages.

  target-i386: bugfix of Intel MPX

The correct size of cpuid 0x0d sub-leaf 4 is 0x40, not 0x10.
This is confirmed by Anvin H Peter and Mallick Asit K.
