[Qemu-devel] Solaris x86_64 configure patch
By default, uname -i returns i86pc on i386 or x86_64 system. This patch makes
it possible to for Solaris systems to get the right hardware type.

Re: [Qemu-devel] Re: PATCH, RFC: Generic DMA framework
I made a first implementation of this concept. CPU-bus uses
southbound functions, device-CPU northbound ones.
The system is not symmetric, the device address range allocation could
well be separate.
What do you think?

[Qemu-devel] Comment for Solaris fix for the HPTC
Compiling the latest CVS code, I found that a function in vl.c uses a define called ULONG_LONG_MAX. The value is defined in solaris's sys/types.h, but only on _LP64 builds, so 32-bit builds won't pickup if I redefine it as ULONG_MAX.
