[Xen-devel] Building Xen 4.8 with GCC 7

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I'm having troubles with building Xen with GCC 7 (Fedora 26). Some of
the problems are fixed by "Compilation fixes for GCC 7" patch series
sent a moment ago, but then I've stumbled on link failure of vtpmmgr
stubdomain, related to some functions of tpm_emulator. I've already tried
with -fkeep-inline-functions, but it only reduced number of errors.
Below is both -fkeep-inline-functions patch and full error message.

Any idea?
