b4f6099b9f MFV r287623: 5997 FRU field not set during pool creation and never
updated

ZFS already supports storing the vdev FRU in a vdev property.  There
is code in libzfs to work with this property, and there is code in
the zfs-retire FMA module that looks for that information.  But there
is no code actually setting or updating the FRU.

To address this, ZFS is changed to send a handful of new events
whenever a vdev is added, attached, cleared, or onlined, as well
as when a pool is created or imported.

Note that syseventd is not currently available on FreeBSD and thus
some work is needed to actually support the new ZFS events (e.g. in
zfsd) to actually use this capability, this changeset is mostly a
diff reduction from upstream.

9888f86a16 - Factor out the common and generic parts of the sparc64 host-PCI-bridge
drivers into the revived sys/sparc64/pci/ofw_pci.c, previously already
  serving a similar purpose. This has been done with sun4v in mind, which
  explains a) the otherwise not that obvious scheme employed and b) why
  reusing sys/powerpc/ofw/ofw_pci.c was even lesser an option.
- Add a workaround for QEMU once again not emulating real machines, in
  this case by not providing the OFW_PCI_CS_MEM64 range. [1]

653809335f MFV r287699: 6214 zpools going south
In r286570 (MFV of r277426) an unprotected write to b_flags to
set the compression mode was introduced.  This would open a race
window where data is partially decompressed, modified, checksummed
and written to the pool, resulting in pool corruption due to the
partial decompression.

Prevent this by reintroducing b_compress

8c4f41ff34 MFV r287624: 5987 zfs prefetch code needs work
Rewrite the ZFS prefetch code to detect only forward, sequential
streams.

The following kstats have been added:

    kstat.zfs.misc.arcstats.sync_wait_for_async

	How many sync reads have waited for async read
	to complete. (less is better)

    kstat.zfs.misc.arcstats.demand_hit_predictive_prefetch

	How many demand read didn't have to wait for I/O
	because of predictive prefetch.  (more is better)

zfetch kstats have been similified to hits, misses, and max_streams,
with max_streams representing times when we were not able to create
new stream because we already have the maximum number of sequences
for a file.

The sysctl variable/loader tunable vfs.zfs.zfetch.block_cap have been
replaced by vfs.zfs.zfetch.max_distance, which controls maximum bytes
to prefetch per stream.

8f875df090 radeon_suspend_kms: don't mess with pci state that's managed by the bus
The pci bus driver handles the power state, it also manages
configuration state saving and restoring for its child devices.  Thus a
PCI device driver does not have to worry about those things.  In fact, I
observe a hard system hang when trying to suspend a system with active
radeonkms driver where both the bus driver and radeonkms driver try to
do the same thing.  I suspect that it could be because of an access to a
PCI configuration register after the device is placed into D3 state.

610141cebb Add stack_save_td_running(), a function to trace the kernel stack of a
running thread.

It is currently implemented only on amd64 and i386; on these
architectures, it is implemented by raising an NMI on the CPU on which
the target thread is currently running. Unlike stack_save_td(), it may
fail, for example if the thread is running in user mode.

This change also modifies the kern.proc.kstack sysctl to use this function,
so that stacks of running threads are shown in the output of "procstat -kk".
This is handy for debugging threads that are stuck in a busy loop.
