[PATCH v7 00/10] Implement support for external IPT monitoring

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This is the next iteration of the external IPT monitoring series, reworked
massively from v6 to fix a whole slew of bugs with the XENMEM_acquire_resource
interface.  It also includes some additional bugfixes to make traced VM's work
when forked.

A branch with all prerequisites is available at:
  
https://xenbits.xen.org/gitweb/?p=people/andrewcoop/xen.git;a=shortlog;h=refs/heads/xen-ipt

This version has undergone basic testing from Michał, Tamas and myself, and
seems to work for the intended usecases.

Andrew Cooper (1):
  xen+tools: Introduce XEN_SYSCTL_PHYSCAP_vmtrace

Michał Leszczyński (7):
  xen/domain: Add vmtrace_frames domain creation parameter
  tools/[lib]xl: Add vmtrace_buf_size parameter
  xen/memory: Add a vmtrace_buf resource type
  x86/vmx: Add Intel Processor Trace support
  xen/domctl: Add XEN_DOMCTL_vmtrace_op
  tools/libxc: Add xc_vmtrace_* functions
  tools/misc: Add xen-vmtrace tool

Tamas K Lengyel (2):
  xen/vmtrace: support for VM forks
  x86/vm_event: Carry Processor Trace buffer offset in vm_event
