Hi! I tried to compile the xen devel (updated with hg today) on Debian Sid and I got the next error (same with gcc 3.4.5 and gcc 4.0.2). CC arch/xen/x86_64/kernel/setup64.o arch/xen/x86_64/kernel/setup64.c:38: error: parse error before "__cpuinitdata" arch/xen/x86_64/kernel/setup64.c:38: warning: type defaults to `int'' in declaration of `__cpuinitdata'' arch/xen/x86_64/kernel/setup64.c:38: error: incompatible types in initialization arch/xen/x86_64/kernel/setup64.c:38: error: initializer element is not constant arch/xen...

Dom0 uses this hypercall to pass ACPI information to Xen. It is not very uncommon for more cpus to be listed in the ACPI tables than are present on the system, particularly on systems with a common BIOS for a 2 and 4 socket server varients. As Dom0 does not control the number of entries in the ACPI tables, and is required to pass everything it finds to Xen, reduce the ERR to an INFO.

Right now, I have lguest in-tree module compiling on x86_64. It's not yet on a sendable state, since the module itself isn't loading. However, this subset of the series is pretty straightforward, and I'm sending it now aiming at reducing the delta size in the future ;-) Have fun,

Hi Jeremy, all, Sorry this took so long, spent last week in Japan at OSDL conf then netconf. After several false starts, I ended up with a very simple implementation, which clashes significantly with your work since then 8(. I've pushed the patches anyway, but it's going to be significant work for me to re-merge them, so I wanted your feedback first. The first patch simply changes

Hi Andi, This is a series of patches based on your latest queue (as of the other day, at least). It includes: - the most recent patch to compute the appropriate amount of percpu space to allocate, using a separate reservation for modules where needed. - make the percpu sections page-aligned, so that percpu variables can be page aligned if needed (which is used by gdt_page) -
