Log Message:
-----------
core: paging: Refactor paging_create/destroy parameters
Change the coherent enum into paging_flags in order to allow adding more
in the future. Rename the flags parameter to access_flags for better
differentiation.
Use this chance to align the names and types of local vars that are
forwarded to access_flags with that parameter.
No behavioral changes.

Log Message:
-----------
core: Introduce JAILHOUSE_MEM_NO_HUGEPAGES memory region flag
This allows to mitigate CVE-2018-12207: On affected Intel machines, a
guest can trigger an unrecoverable machine check exception when running
a certain code pattern on an executable huge page. The suggested
mitigation pattern of Intel involves on-demand break-up of huge pages
when the guest tries to execute on them and also consolidating them into
non-executable huge pages dynamically. This pattern is not compatible
with the static and deterministic behavior of Jailhouse.
Therefore, this introduces a memory region flag to exclude huge page
mappings for a region. System configurators can use this flag for
executable regions on affected CPUs, while still allowing huge pages for
non-executable regions.
PAGING_HUGE/NO_HUGE is consistently applied to all caller of
paging_create, using NO_HUGE in case only a size known to be smaller
than a huge page is requested.

This field is static, thus volatile is not appropriate. Rephrase the

Documentation: Update hypervisor interfaces specification
Lots of things changed since the file was last touched. Add the
hypercall ABIs for non-Intel-x86, update the "CPU Get Info" hypercall
with new statistic types, and extend the Comm Region description with
the console and non-x86 extensions added meanwhile.
