Internal ioreq servers are plain function handlers implemented inside

The new format specifier is '%pp', and prints a pci_sbdf_t using the
seg:bus:dev.func format. Replace all SBDFs printed using
'%04x:%02x:%02x.%u' to use the new format specifier.
No functional change intended.

Using clang and lld 8 requires installing the packages from the
official llvm apt repositories, so modify the Debian Docker files for
stretch and unstable to add the llvm repo and install clang and lld
from it.
Also add some jobs to test building Xen with clang 8 and lld.

As long as the memory stolen is always above 1MB. This allows the PVH
Dom0 builder to be used on a memory map that only has a single RAM
region starting at 0.

Hello,
This series contains some trivial bug fixes for the PVH dom0 builder and
an improvement when filling the p2m so that alignment is taken into
account when allocating and populating the p2m.
Thanks, Roger.

order allocations that start on a non-aligned address to be broken
down into lower order entries on the p2m page tables.
Fix this by taking into account the
