The GELI boot code rounds reads up to 4k, since the encrypted sectors are
4k, and must be decrypted as a unit. With oddball sized disks (almost
always virtual), this can lead to reading past the end of the disk.

For most regulators, the regulator_stop() method can be transformed to
regulator disable. But, in some cases, we needs to maintain shared data
across multiple regulators (e.g. single GPIO pin which works as enable
for multiple regulates). In this case, the implementation of regulator
should perform his own enable counting therefore it is necessary to
distinguish between the regulator enable/disable method (which
increments/decrements enable counter for shared resource) and regulator
stop method (which don't affect it).
So:
- add regnode_stop() method to regulator framework and default it to
regnode_enable(..., false, ...)
- implement it in regulator_fixed with proper enable counting.
While I'm in, also fix handling of always_on property. If any of regulators
sharing same GPIO pin have it enabled, then none of them can disable regulator.

`rdev` and `disk` serve the same purpose, read the partition table without
the `d_offset` or `d_slice` set, so the read is relative to the start of
the disk. Reuse the already initialized `disk` instead of making another
copy later.

This command can be used by a sysadmin to either copy or migrate a data
file on one DS to another DS.
Its main use is to recover data files onto a mirrored DS after the DS has
been repaired and brought back online.
This command allows a sysadmin to display or modify the pnfsd.dsfile extended
attribute used by the pNFS MDS server in various ways.
Its main use is to set a DS's IP address to 0.0.0.0 when that DS has failed,
so that it will not be used for the file when brought back online after

callback to do the checks.
This will allow us to have a more graceful fallback code. In the
future, it's anticipated that we may fallback to a more global search
(or implement a command to do so) when reqeusted by the user, or we
detect a violation of the UEFI Boot Manager protocol severe enough to
warrant this backstop. For now, it just allows us to get rid of img as

Newer OPAL device trees, such as those on POWER9 systems, use 'pciex' for

This could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.
This now ensures that build-tools targets have 'make obj' ran if needed.
This is especially problematic for pmu-events since it is not directly
connected in the build. Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc. Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.
