Currently building gdbsx with clang 3.8 gives the following errors:
xg_main.c:783:17: error: 'aligned' attribute ignored when parsing type
[-Werror,-Wignored-attributes]
iop->uva = (uint64_aligned_t)((unsigned long)tobuf);

Clang complains:

Since sd_notify_fd has a signature of unit -> unit, we simply change
the return value to Val_unit.

This patch adds access control for NPT mode.
There aren’t enough extra bits to store the access rights in the NPT p2m
table, so we add a radix tree to store the rights. For efficiency,
remove entries which match the default permissions rather than
continuing to store
The calls to xpti_init_default() in parse_xpti() are buggy. The CPUID data
hasn't been fetched that early, and boot_cpu_has(X86_FEATURE_ARCH_CAPS) will
always evaluate false.
As a result, the default case won't disable XPTI on Intel hardware which
advertises ARCH_CAPABILITIES_RDCL_NO.
Simplify
It turns out that nothing ever prevented HVM guests from trying to set unknown
EFER bits. Generally, this results in a vmentry failure.
For Intel hardware, all implemented bits are covered by the checks.
For AMD hardware, the only EFER bit which isn't covered by the checks is TCE
(which AFAICT

So it is an error to unmap the page successfully? In fact this same line

Hello,
For the last few days, I have been trying to get a PVH dom0 running,
however I encountered the following problem: the system seems to
freeze after the hypervisor boots, the screen goes black. I have tried to
debug it via a serial console (using Minicom) and managed to get some

Those 2 options do nothing. So I would prefer if they are removed. With

Add support for Linux grant device driver extension which allows
converting existing dma-buf's into an array of grant references
and vise versa. This is only implemented for Linux as other OSes
have no Linux dma-buf support.
