Several PV drivers (both historically and currently [1]) report errors
by writing text into /local/domain/$DOMID/error. This patch creates the
node in libxl and makes it writable by the domain, and also adds some
text into xenstore-paths.pandoc to state what the node

Hi,
I'm trying to determine the status of HYPERVISOR_xenoprof_op. The code behind
it appears to be unmaintained and I cannot find any
support statement for it. Googling around finds some mentions of Xen and
oprofile but it's not clear whether it works and most
references I find are quite old.

There does not seem to be any justification for refusing to create the
domain's p2m table simply because it may have assigned pages. Particularly
it prevents the prior allocation of PGC_extra pages.

Patches #2 and #3 have been split out of the previous version of patch #6
(which was patch #2 of the previous series). Patch #4 is not entirely
related but is useful to have in place before patch #5. Patch #5 is also
new.
Paul Durrant (6):
domain: introduce alloc/free_shared_info() helpers
is_xen_heap_page() it should also check for
the PGC_extra bit in 'count_info'.
This patch therefore defines is_special_page() to cover both cases and
converts tests if is_xen_heap_page() to is_special_page() where
appropriate.

This patch fixes Coverity issue CID 1459006 (Insecure data handling
(INTEGER_OVERFLOW)).
The problem is that the error paths for libxl__mark_domid_recent() and
libxl__is_domid_recent() check the 'f' field in struct libxl__domid_history
when it may not have been initialized.

libxl Makefile was not updated to add '-lrt' so the build will fail in
that environment.
This patch simply adds '-lrt' to LIBXL_LIBS unconditionally, as it does
no harm in newer environments.

Hence the need to save the MFN.
NOTE: Whist defining the new helpers, virt_to_mfn() in common/domain.c
is made type safe.
The definition of nmi_reason() in asm-x86/shared.h is also re-
flowed to avoid overly long lines.

v5:
- Expand the commit comment
Some code-paths use values other than INVALID_DOMID to indicate an invalid
domain id. Specifically, xl will pass a value of 0 when creating/restoring
a domain. Therefore modify libxl__logv() to use libxl_domid_valid_guest()
as a validity test.

it with other domid-related defitions.

A subsequent patch will modify libxl to allow selection of a random domid
value when creating domains. Valid values are limited to a width of 15 bits,
so add an appropriate mask definition to the public header.
