Previously, if a system had multiple batteries, the remaining life
percentage was calculated as the average of each battery's percent
remaining. This results in rather incorrect values when you consider the
case of the Thinkpad X270 that has a small 3 cell internally battery, and
a hot-swappable 9 cell battery that is used first. Battery 0 is at 100%,
but battery 1 is at 10%, you do not infact have 55% of your capacity
remaining.
The new method calculates the percentage based on remaining capacity
out of total capacity, giving a much more accurate reading.

Using the latest NVIDIA driver, upon resuming from suspend with X
running the display remained blank. Additionally OpenGL applications
that were running triggered a number of error messages from the NVIDIA
driver.
This occurred because the vt efifb back-end did not signal the X server
to release the display before suspending (or to re-acquire it after
resuming). The NVIDIA driver includes code for smoothly shutting down
and re-initializing the GPU, which was not getting called.
Since the NVIDIA driver doesn't currently support framebuffer devices
and vt is forced to fall back to the efifb back-end, add vd_suspend and
vd_resume members to connect the suspend/resume path. This ensures the
X server is properly able to re-initialize the display.

This is not completely necessary today, but this change is being made in a
conservative manner to avoid accidental breakage in the future, if this ever
was a unicode string.
PR: 237403
MFC after: 1 week
In python 3, the default encoding was switched from ascii character sets to
unicode character sets in order to support internationalization by default.
Some interfaces, like ioctls and packets, however, specify data in terms of
non-unicode encodings formats, either in host endian (`fcntl.ioctl`) or
network endian (`dpkt`) byte order/format.
This change alters assumptions made by previous code where it was all
data objects were assumed to be basestrings, when they should have been
treated as byte arrays. In order to achieve this the following are done:
* str objects with encodings needing to be encoded as ascii byte arrays are
done so via `.encode("ascii")`. In order for this to work on python 3 in a
type agnostic way (as it anecdotally varied depending on the caller), call
`.encode("ascii")` only on str objects with python 3 to cast them to ascii
byte arrays in a helper function name `str_to_ascii(..)`.
* `dpkt.Packet` objects needing to be passed in to `fcntl.ioctl(..)` are done
so by casting them to byte arrays via `bytes()`, which calls
`dpkt.Packet__str__` under the covers and does the necessary str to byte array
conversion needed for the `dpkt` APIs and `struct` module.
In order to accomodate this change, apply the necessary typecasting for the
byte array literal in order to search `fop.name` for nul bytes.
This resolves all remaining python 2.x and python 3.x compatibility issues on
amd64. More work needs to be done for the tests to function with i386, in
general (this is a legacy issue).

Make `KAT(CCM)?Parser` into a context suite-capable object by implementing
`__enter__` and `__exit__` methods which manage opening up the file descriptors
and closing them on context exit. This implementation was decided over adding
destructor logic to a `__del__` method, as there are a number of issues around
object lifetimes when dealing with threading cleanup, atexit handlers, and a
number of other less obvious edgecases. Plus, the architected solution is more
pythonic and clean.
Complete the iterator implementation by implementing a `__next__` method for
both classes which handles iterating over the data using a generator pattern,
and by changing `__iter__` to return the object instead of the data which it
would iterate over. Alias the `__next__` method to `next` when working with
python 2.x in order to maintain functional compatibility between the two major
versions.
As part of this work and to ensure readability, push the initialization of the
parser objects up one layer and pass it down to a helper function. This could
have been done via a decorator, but I was trying to keep it simple for other
developers to make it easier to modify in the future.

all-ones then carving out blocks of zeroes where specified values go, init
it to all-zeroes, put in ones where values need to be masked, then use it
as value &= ~sc_led_modes_mask. In addition to being more idiomatic, this
means everything related to FDT data is initialized to zero along with the
rest of the softc, and that allows removing some #ifdef FDT sections and
wrapping the whole muge_set_leds() function in a single ifdef block.
This also deletes the early-out from muge_set_leds() when an eeprom exists.

should override that, because the user is in control of the fdt data.

The ad-hoc code this replaces could find the wrong instance if multiple

The .init and .fini epilogues from crtn should be placed immediately
after any instructions in .init and .fini sections from the linked
objects. Using 16-byte alignment for the epilogues on MIPS was a bug,
but it did not cause any issue with GNU ld as GNU ld (2.17.50) fills the
padding with NOPs.
Current versions of LLD fill any padding between different object files
with trap instructions. Inserting trap padding prior to the .init/.fini
epilogue is undesriable as the resulting binary will crash at runtime.
The .init and .fini sections in object files linked between crti and
crtn must already be a multiple of the instruction size and so no
alignment directive is required in crtn. Indeed, other architectures
(except sparc64) do not specify alignment in their crtn implementations.
