The current reboot command in efi/loader/main.c is passing extra data with
ResetSystem, however, UEFI spec 2.6, page 265 does state:
"ResetData is only valid if ResetStatus is something other than EFI_SUCCESS
unless the ResetType is EfiResetPlatformSpecific where a minimum amount of
ResetData is always required."
Therefore we should use DataSize 0 and ResetData NULL - those are two last
arguments for the call.

Despite the comment in code (which was misleading), the indirect access is
only used to read the switch CONFIG data from the scrap register and not
for the GLOBAL2 access.
Use the dsa data to define when the switch is in the Multi Chip Addressing

The code specified the length of a layout as INT64_MAX instead of
UINT64_MAX. This could result in getting a layout for less than the
full file for extremely large files. Although having little practical
effect, this patch corrects this in the code.

In exceptional circumstances, an MCA exception will trigger when the
freelist is exhausted. In such a case, no error will be logged on the list
and 'mca_count' will not be incremented.
Prior to this patch, all CPUs that received the exception would spin
forever.
With this change, the CPU that detects the error but finds the freelist
empty will proceed to panic the machine, ending the deadlock.

7740 fix for 6513 only works in hole punching case, not truncation
illumos/illumos-gate@7de35a3ed07de35a3ed0https://www.illumos.org/issues/7740
The problem is that dbuf_findbp will return ENOENT if the block it's
trying to find is beyond the end of the file. If that happens, we assume
there is no birth time, and so we lose that information when we write
out new blkptrs. We should teach dbuf_findbp to look for things that are
beyond the current end, but not beyond the absolute end of the file.
To verify, create a large file, truncate it to a short length, and then
write beyond the end. Check with zdb to make sure that there are no
holes with birth time zero (will appear as gaps).

7743 per-vdev-zaps have no initialize path on upgrade
illumos/illumos-gate@555da5111b555da5111bhttps://www.illumos.org/issues/7743
When loading a pool that had been created before the existance of
per-vdev zaps, on a system that knows about per-vdev zaps, the
per-vdev zaps will not be allocated and initialized.
This appears to be because the logic that would have done so, in
spa_sync_config_object(), is not reached under normal operation. It is
only reached if spa_config_dirty_list is non-empty.
The fix is to add another `AVZ_ACTION_` enum that will allow this code
to be reached when we detect that we're loading an old pool, even when
there are no dirty configs.

Some notes:
- Only i386 and amd64 layouts are checked, other Tier-1 (or close to
it) architectures would benefit from the same check.
- Unconditional enabling of the asserts depend on the stability of locks
memory layout. If locks are optimized to avoid bloat when some debugging
or profiling features turned off, it makes sense to only assert layout
for production configs.

- Rename the default implementation of 'pcib_request_feature' and add
a pcib_request_feature() wrapper function (as is often done for
new-bus APIs implemented via kobj) that accepts a single function.
Previously the call to pcib_request_feature() ended up invoking the
method on the great-great-grandparent of the bridge device instead
of the grandparent. For a bridge that was a direct child of pci0 on
x86 this resulted in the method skipping over the Host-PCI bridge
driver and being invoked against nexus0
- When invoking _OSC from a Host-PCI bridge driver, invoke
device_get_softc() against the Host-PCI bridge device instead of the
child bridge that is requesting HotPlug. Using the wrong softc data
resulted in garbage being passed for the ACPI handle causing the
_OSC call to fail.
- While here, perform some other cleanups to _OSC handling in the ACPI
Host-PCI bridge driver:
- Don't invoke _OSC when requesting a control that has already been
granted by the firmware.
- Don't set the first word of the capability array before invoking
_OSC. This word is always set explicitly by acpi_EvaluateOSC()
since it is UUID-independent.
- Don't modify the set of granted controls unless _OSC doesn't exist
(which is treated as always successful), or the _OSC method
doesn't fail.
- Don't require an _OSC status of 0 for success. _OSC always
returns the updated control mask even if it returns a non-zero
status in the first word.
- Whine if _OSC ever tries to revoke a previously-granted control.
(It is not supposed to do that.)
- While here, add constants for the _OSC status word in acpivar.h
(though currently unused).

7606 dmu_objset_find_dp() takes a long time while importing pool
illumos/illumos-gate@7588687e6b7588687e6bhttps://www.illumos.org/issues/7606
When importing a pool with a large number of filesystems within the same
parent filesystem, we see that dmu_objset_find_dp() takes a long time.
It is called from 3 places: spa_check_logs(), spa_ld_claim_log_blocks(),
and spa_load_verify().
There are several ways to improve performance here:
1. We don't really need to do spa_check_logs() or
spa_ld_claim_log_blocks() if the pool was closed cleanly.
2. spa_load_verify() uses dmu_objset_find_dp() to check that no
datasets have too long of names.
3. dmu_objset_find_dp() is slow because it's doing
zap_value_search() (which is O(N sibling datasets)) to determine
the name of each dsl_dir when it's opened. In this case we
actually know the name when we are opening it, so we can provide
it and avoid the lookup.
This change implements fix#3 from the above list; i.e. make
dmu_objset_find_dp() provide the name of the dataset so that we don't
have to search for it.
