Hi,
Compiling the xen kernel fails with:
xen/arch/x86/domain.c: In function 'alloc_domain_struct'
xen/arch/x86/domain.c:191: error: negative width in bit-field '<anonymous>'
Problem is that struct domain has grown bigger than a page for some reason,
in your build environment.
Oh, local changes caused this. Thanks for the hint.

I can't reproduce this.
Removing the line
BUILD_BUG_ON(sizeof(*d)> PAGE_SIZE);
makes xen kernel compile again.
But not actually work properly. We only allocate a single page for the
domain struct. If the struct is bigger than a page, you'll get memory
corruption at run time.
