clang 5.0 changed the layout of the type_mismatch_data structure and
introduced __ubsan_handle_type_mismatch_v1 and
__ubsan_handle_pointer_overflow.
This commit adds support for the new structure layout, adds the
missing handlers and the new types for type_check_kinds.

New definitions provide a convenient way of accessing contents of
VMX MSRs. They are separated into 5 logical blocks:
1. vmx: [VMX_BASIC, VMX_VMCS_ENUM]
2. VMX_PROCBASED_CTLS2
3. VMX_EPT_VPID_CAP
4. vmx_true_ctls: [VMX_TRUE_PINBASED_CTLS, VMX_TRUE_ENTRY_CTLS]

Add calculate_raw_vmx_policy() which fills Raw policy with H/W values
of VMX MSRs. Host policy will contain a copy of these values.

The end goal of having VMX MSRs policy is to be able to manage

Currently, when nested virt is enabled, the set of L1 VMX features
is fixed and calculated by nvmx_msr_read_intercept() as an intersection
between the full set of Xen's supported L1 VMX features, the set of
actual H/W features and, for MSR_IA32_VMX_EPT_VPID_CAP, the set of
features that Xen uses.
With the new cpuid infrastructure there is a domain-wide struct cpuid
policy and there is no need to pass a separate struct vcpu * into
hvm_cr4_guest_valid_bits() anymore. Make the function accept struct

Availability of some MSRs depends on certain CPUID bits. Add function
recalculate_domain_msr_policy() which updates availability of per-domain
MSRs based on current domain's CPUID policy. This function is called
when CPUID policy is changed from a toolstack.
Add recalculate_domain_vmx_msr_policy()
Now that each domain has a correct view of VMX MSRs in it's per-domain
MSR policy, it's possible to handle guest's RD/WRMSR with the new
handlers. Do it and remove the old nvmx_msr_read_intercept() and
associated bits.
There is no functional change to what a guest sees in VMX MSRs.

Hello,
The following series contain an implementation of handlers for the PCI
configuration space inside of Xen. This allows Xen to detect accesses
to the PCI configuration space and react accordingly.
Why is this needed? IMHO, there are two main points of doing all this
emulation inside of Xen,
I appear to receive this series out of order.
This one appears in my inbox later then "xenconsole: Change the type of
ring_ref to xen_pfn_t in console_create_ring", which at a glance depends
on this one.
Please resend this series with proper numbering.

Instead of asserting the receive interrupt (RXI) on the first character
in the FIFO, lets (ab)use the receive timeout interrupt (RTI) for that
purpose. That seems to be closer to the spec and what hardware does.
Improve the readability of vpl011_data_avail() on the way.

Provide XEN_DMOP_add_to_physmap, a limited version of
XENMEM_add_to_physmap to allow a deprivileged QEMU to move VRAM when a
guest programs its BAR. It is equivalent to XENMEM_add_to_physmap with
space == XENMAPSPACE_gmfn.

The recently added support for restricting QEMU prevents use of the VGA
console. This series addresses that by adding a couple of new dmops.
A corresponding patch for QEMU is needed to make use of the new dmops.
