Changes since v3:
- using bitmap_set() instead of set_bit() in numa_add() routine.
- removed call to bitmak_zero() since bitmap_new() also zeros' the bitmap.
- Rebased to the latest qemu.
Changes since v2:
- Using "unsigned long *" for the node_cpumask[].
- Use bitmap_new() instead
The reason why softmmu condition in configure is that softmmu is thought to be

To avoid compilation error, it needs more macros in other sources, such as,

This patchset adds support for booting with >4GB of RAM on the
Versatile Express Cortex-A15 model. There are some caveats:
* you need an LPAE A15 kernel
* you need to be booting with device tree
* your device tree blob needs to specify #address-cells and
#size-cells as 2

This version uses CLOCK_MONOTONIC for the timeout to avoid jumps on wall

(I also like it more this way, since semaphores model well the

The Win32 implementation only accepts EventNotifiers, thus a few
drivers are disabled under Windows. It is possible to use the
same techniques in main-loop.c and reenable them; alternatively,
the drivers can be changed to use threads instead of non-blocking
I/O.
