Linus Torvalds 9c4bc1c2be Merge branch 'stable/gntdev' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
* 'stable/gntdev' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/p2m: Fix module linking error.
  xen p2m: clear the old pte when adding a page to m2p_override
  xen gntdev: use gnttab_map_refs and gnttab_unmap_refs
  xen: introduce gnttab_map_refs and gnttab_unmap_refs
  xen p2m: transparently change the p2m mappings in the m2p override
  xen/gntdev: Fix circular locking dependency
  xen/gntdev: stop using "token" argument
  xen: gntdev: move use of GNTMAP_contains_pte next to the map_op
  xen: add m2p override mechanism
  xen: move p2m handling to separate file
  xen/gntdev: add VM_PFNMAP to vma
  xen/gntdev: allow usermode to map granted pages
  xen: define gnttab_set_map_op/unmap_op

menu "Xen driver support"
depends on XEN
config XEN_BALLOON
bool "Xen memory balloon driver"
default y
help
The balloon driver allows the Xen domain to request more memory from
the system to expand the domain's memory allocation, or alternatively
return unneeded memory to the system.
config XEN_SCRUB_PAGES
bool "Scrub pages before returning them to system"
depends on XEN_BALLOON
default y
help
Scrub pages before returning them to the system for reuse by
other domains. This makes sure that any confidential data
is not accidentally visible to other domains. Is it more
secure, but slightly less efficient.
If in doubt, say yes.
config XEN_DEV_EVTCHN
tristate "Xen /dev/xen/evtchn device"
default y
help
The evtchn driver allows a userspace process to triger event
channels and to receive notification of an event channel
firing.
If in doubt, say yes.
config XEN_BACKEND
bool "Backend driver support"
depends on XEN_DOM0
default y
help
Support for backend device drivers that provide I/O services
to other virtual machines.
config XENFS
tristate "Xen filesystem"
default y
help
The xen filesystem provides a way for domains to share
information with each other and with the hypervisor.
For example, by reading and writing the "xenbus" file, guests
may pass arbitrary information to the initial domain.
If in doubt, say yes.
config XEN_COMPAT_XENFS
bool "Create compatibility mount point /proc/xen"
depends on XENFS
default y
help
The old xenstore userspace tools expect to find "xenbus"
under /proc/xen, but "xenbus" is now found at the root of the
xenfs filesystem. Selecting this causes the kernel to create
the compatibility mount point /proc/xen if it is running on
a xen platform.
If in doubt, say yes.
config XEN_SYS_HYPERVISOR
bool "Create xen entries under /sys/hypervisor"
depends on SYSFS
select SYS_HYPERVISOR
default y
help
Create entries under /sys/hypervisor describing the Xen
hypervisor environment. When running native or in another
virtual environment, /sys/hypervisor will still be present,
but will have no xen contents.
config XEN_XENBUS_FRONTEND
tristate
config XEN_GNTDEV
tristate "userspace grant access device driver"
depends on XEN
select MMU_NOTIFIER
help
Allows userspace processes to use grants.
config XEN_PLATFORM_PCI
tristate "xen platform pci device driver"
depends on XEN_PVHVM && PCI
default m
help
Driver for the Xen PCI Platform device: it is responsible for
initializing xenbus and grant_table when running in a Xen HVM
domain. As a consequence this driver is required to run any Xen PV
frontend on Xen HVM.
config SWIOTLB_XEN
def_bool y
depends on PCI
select SWIOTLB
