No, I'm yet to setup such a web page.. However for your first
questions, here is the related internal report:
Subject: [xen:devel/pvh.5 2/8] arch/x86/xen/smp.c:329:7: error: 'struct
vcpu_guest_context' has no member named 'u'

Hi Konrad,
FYI, kernel build failed on
tree: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/pvh.5
head: dfc557a5c9a519b45b79ad059821db15bad229fa
commit: 4d80210f4948a962c9ecca2773da69c0b2affb62 [2/8] xen/smp: Move the common CPU init code a bit to prep for PVH patch.
config: x86_64-allyesconfig # make ARCH=x86_64 allyesconfig

Note: the xen/devel/pvh.5 HEAD dfc557a builds fine.
It only hurts bisectibility.
All error/warnings:
