KVM uses anon_inode_get() to allocate file descriptors as part
of some of its ioctls. But those ioctls are lacking a flag argument

Sounds a lot like InfiniBand subsystem behavor: IB file descriptors
are of no use accross exec() since memory mappings tied to those fds
won't be available in the new process:

Hi,
Following a patchset asking to change calls to get_unused_flag() [1]
to use O_CLOEXEC, Alex Williamson [2][3] decided to change VFIO
to use the flag.
Since it's a related subsystem to KVM, using O_CLOEXEC for

Currently we are not saving and restoring the SIAR and SDAR registers in
the PMU (performance monitor unit) on guest entry and exit. The result
is that performance monitoring tools in the guest could get false
information about where a program was executing and what data it was
accessing at the
This adds one_reg register numbers for two performance monitor registers
that exist on POWER7 and later processors (SIAR and SDAR) and three that
will be introduced on POWER8 (MMCR2, MMCRS and SIER).

This allows guests to have a different timebase origin from the host.
This is needed for migration, where a guest can migrate from one host
to another and the two hosts might have a different timebase origin.
However, the timebase seen by the guest must not go backwards, and
should go forwards
Here are 3 patches that add two PMU (performance monitor unit)
registers to the set being context-switched on guest entry and exit,
and implement a per-guest timebase offset that is needed when we
migrate a guest from one host to another that has a different timebase
origin. The first patch just
