TMPFS_PAGES_MINRESERVED controls how much memory is reserved for the system
and not used by tmpfs.
On very small memory systems, the default value may be too high and this
prevents these small memory systems from using reroot, which is required
for them to install firmware updates.

VGLBitmapString() and VGLSetBorder() so as to not truncate to 8 bits.
Complete the corresponding fix for VGLGetXY() and VGLPutXY() (parts
of the man page were out of date).
Since the font format is undocumented, it is unclear how non-multiples
of 8 should be padded to bytes in the font file. Use the same
representation as bdf text format (big- endian, with padding in the
lower bits).
There seems to be no alternative to reading each plane independently using
3 slow i/o's per plane (this delivers 8 nearby pixels, but we don't buffer
the results so run 8 times slower than necessary.
All the code for this was there, but it was ifdefed out and replaced by
simpler code that cannot work in planar modes. The ifdefed out code
was correct except it was missing a volatile declaration, so compilers
optimized the multiple dummy reads in it to a single read.
While geom_flashmap has always supported label names for its slices, it does
so by appending "s.labelname" to the provider device name, meaning you still
have to know the name and unit of the hardware device to use the labels.
These changes add support for device-independent geom_flashmap labels, using
the standard geom_label infrastructure. geom_flashmap now creates a softc
struct attached to its geom, and as it creates slices it stores the label
into an array in the softc. The new geom_label_flashmap uses those labels
when tasting a geom_flashmap provider.

Support for 16-bit and 32-bit Truecolor modes was supposed to be
complete in r70991 of main.c and in nearby revisions for other files, but
it was broken by the overruns in most cases (all cases were the mouse
is enabled, and most cases where bitmaps are used). r70991 also
uninintentionally added support for depths 9-15, 17-23 and 25-31.
Depth 24 was more obviously broken and its support is ifdefed out. In
the other ranges, only depth 15 is common. It was broken by buffer
overruns in all cases.
bitmap.c:
- the static buffer was used even when it was too small (but it was
large enough to often work accidentally in depth 16)
- the size of the dynamically allocated buffer was too small
- the sizing info bitmap->PixelBytes was not inititialzed in the bitmap
constructor. It often ended up as 0 for MEMBUFs, so using it in more
places gave more null pointer accesses. (It is per-bitmap, but since
conversion between bitmaps of different depths is not supported (except
from 4 bits by padding to 8), it would work better if it were global.)
main.c:
- depths were rounded down instead of up to a multiple of 8, so PixelBytes
was 1 too small for depths above 8 except 16, 24 and 32.
- PixelBytes was not initialized for 4-bit planar modes. It isn't really
used for frame buffer accesses in these modes, but needs to be 1 in
MEMBUF images.
mouse.c:
- the mouse cursor buffers were too small.
vgl.h:
- PixelBytes was not initialized in the static bitmap constructor. It
should be initialized to the value for the current mode, but that is
impossible in a static constructor. Initialize it to -1 so as to
fail if it is used without further initialization.
All modes that are supposed to be supported now don't crash in
nontrivial tests, and almost work. Missing uses of PixelBytes now
give in-bounds wrong pointers instead of overruns. Misconversions of
bitmaps give multiple miscolored mouse cursors instead of 1 white one,
and similarly for bitmaps copied through a MEMBUF.
The values of the d_slice and d_partition fields of a disk_devdesc have a
few values with special meanings in the disk_open() routine. Through various
evolutions of the loader code over time, a d_partition value of -1 has
meant both "use the first ufs partition found in the bsd label" and "don't
open a bsd partition at all, open the raw slice."
This defines a new special value of -2 to mean open the raw slice, and it
gives symbolic names to all the special values used in d_slice and
d_partition, and adjusts all existing uses of those fields to use the new
constants.
The phab review for this timed out without being accepted, but I'm still
citing it below because there is useful commentary there.

There are only 19 bytes available for the name of an interrupt plus the
name(s) of handlers/drivers using it. There is a mechanism from the days of
shared interrupts that replaces some of the handler names with '+' when they
don't all fit into 19 bytes.
In modern times there is typically only one device on an interrupt, but long
device names are the norm, especially with embedded systems. Also, in systems
with multiple interrupt controllers, the names of the interrupts themselves
can be long. For example, 'gic0,s54: imx6_anatop0' doesn't fit, and
replacing the device driver name with a '+' provides no useful info at all.
When there is only one handler but its name was too long to fit, this
change truncates enough leading chars of the handler name (replacing them
with a '-' char to indicate that some chars are missing) to use all 19
bytes, preserving the unit number typically on the end of the name. Using
the prior example, this results in: 'gic0,s54:-6_anatop0' which provides
plenty of info to figure out which device is involved.

Attempting to build www/firefox on POWER9 resulted in a HMI exception being
thrown, a fatal trap currently. This is typically caused by timer facility
errors, but examination of the Hypervisor Maintenance Exception Register
(HMER) yielded only that an exception had recovered, with no information of
the actual exception cause.
When an HMI occurs, OPAL_HANDLE_HMI or OPAL_HANDLE_HMI2 must be called to
handle the exception at the firmware level. If the exception is handled, we
can continue.
This adds only the preliminary handler, enough to prevent package building
from panicking. An enhancement in the future is to use the flags returned
by OPAL_HANDLE_HMI2 to print more useful error messages, and log maintenance
events.
