Any geom class using g_metadata_store, as well as geom_virstor which
duplicated g_metadata_store internally, would dump sectorsize - mdsize bytes
of userspace memory following the metadata block stored. This is most or all
geom classes (gcache, gconcat, geli, gjournal, glabel, gmirror, gmultipath,
graid3, gshsec, gstripe, and geom_virstor).

We currently initialize the vm_page array in three passes: one to zero
the array, one to initialize the "order" field of each page (necessary
when inserting them into the vm_phys buddy allocator one-by-one), and
one to initialize the remaining non-zero fields and individually insert
each page into the allocator.
Merge the three passes into one following a suggestion from alc:
initialize vm_page fields in a single pass, and use vm_phys_free_contig()
to efficiently insert physical memory segments into the buddy allocator.
This reduces the initialization time to a third or a quarter of what it
was before on most systems that I tested.

17h supports MCA thresholding in the same way as 16h and earlier.
Supposedly a ScalableMca feature bit in CPUID 8000_0007:EBX must be set, but
that was not true for earlier models, so be careful about relying on it.
While here, document a missing bit in LS MCA MISC0.

Add basic command line parsing test coverage for these utilities. The tests
were automatically generated based on their man pages. These tests can be
expanded by hand for more thorough coverage. The aim is to generate very
basic amount of test coverage for all the utilities in the base system.

add a macro to access it. This seems to be safe for older CPUs to read this
new register, with them returning zero.

efidp_size will return the size, in bytes, of a EFI device path

other linux routines. It's implemented by GetDevicePathSize from EDK2

Rename boot1's wcslen to ucs2len, which we can't use in userland
because wchar in userland is unsigned, not short. Move it into
efichar.c. Also spell '* 2' as '* sizeof(efi_char)' and add 1 for the
trailing NUL to transition the FreeBSD boot env vars to being NUL
terminated on the same line...

When bcopy is treated as memcpy/memmove, Clang produces warnings that the
size argument doesn't match the type of the source. This is true, it
doesn't match; we're aliasing the source.
Explicitly cast the source pointer to the expected type to remove the
warning.

return values that the userland 32-bit code is not going

This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.
