Michael Tokarev 51b0c6065a fix crash in migration, 32-bit userspace on 64-bit host 
This change fixes a long-standing immediate crash (memory corruption
and abort in glibc malloc code) in migration on 32bits.

The bug is present since this commit:

  commit 692d9aca97b865b0f7903565274a52606910f129
  Author: Bruce Rogers <brogers@novell.com>

    qemu-kvm: allocate correct size for dirty bitmap

    The dirty bitmap copied out to userspace is stored in a long array,
    and gets copied out to userspace accordingly.  This patch accounts
    for that correctly.  Currently I'm seeing kvm crashing due to writing
    beyond the end of the alloc'd dirty bitmap memory, because the buffer
    has the wrong size.

 --- a/qemu-kvm.c
 +++ b/qemu-kvm.c
 @@ int kvm_get_dirty_pages_range(kvm_context_t kvm, unsigned long phys_addr,
 -            buf = qemu_malloc((slots[i].len / 4096 + 7) / 8 + 2);
 +            buf = qemu_malloc(BITMAP_SIZE(slots[i].len));
             r = kvm_get_map(kvm, KVM_GET_DIRTY_LOG, i, buf);

BITMAP_SIZE is now open-coded in that function, like this:

 size = ALIGN(((mem->memory_size) >> TARGET_PAGE_BITS), HOST_LONG_BITS) / 8;

The problem is that HOST_LONG_BITS in 32bit userspace is 32
but it's 64 in 64bit kernel.  So userspace aligns this to
32, and kernel to 64, but since no length is passed from
userspace to kernel on ioctl, kernel uses its size calculation
and copies 4 extra bytes to userspace, corrupting memory.

Here's how it looks like during migrate execution:

our=20, kern=24
our=4, kern=8
...
our=4, kern=8
our=4064, kern=4064
our=512, kern=512
our=4, kern=8
our=20, kern=24
our=4, kern=8
...
our=4, kern=8
our=4064, kern=4064
*** glibc detected *** ./x86_64-softmmu/qemu-system-x86_64: realloc(): invalid next size: 0x08f20528 ***

(our is userspace size above, kern is the size as calculated
by the kernel).

Fix this by always aligning to 64 in a hope that no platform will
have sizeof(long)>8 any time soon, and add a comment describing it
all.  It's a small price to pay for bad kernel design.

Alternatively it's possible to fix that in the kernel by using
different size calculation depending on the current process.
But this becomes quite ugly.

Special thanks goes to Stefan Hajnoczi for spotting the fundamental
cause of the issue, and to Alexander Graf for his support in #qemu.
