X_db_search_symbol(). Otherwise we don't see important symbols in
non-verbosely written assembler code.
NetBSD already has this. The kld version already has a stronger form
of it without really trying -- linker_ddb_search_symbol() doesn't
support ddb's symbol search strategy parameter, so the kld
X_db_search_symbol() doesn't pass the parameter to linker_ddb...() and
linker_ddb...() doesn't make distinctions based on the symbol type.
db_elf.c now works better than db_kld.c when it works (which is essentially
when there are no modules except the kernel). It works after booting
with -d. db_kld.c doesn't work until lots of SYSINIT()s have run.
symbol table sections. Reconstruct the necessary section headers from
(ksym_start, ksym_end). This was much easier than converting to use
module metadata, and just works for static symbols, unlike db_kld when
there is no module metadata. Initialize (ksym_start, ksym_end) from
bootinfo on i386's only.
The boot loader should load section headers for all sections that it
loads, and apparently did this for at least the symbol table sections
when this file last worked under FreeBSD (on alphas only) and always
did this under NetBSD (where this file was obtained from). At least
on i386's, boot2 discards the section headers (except for converting
them to (bootinfo.bi_symtab, bootinfo.bi_esymtab), and as far as I can
tell, loader(8) discards them apart from converting them to the bootinfo
values and module metadata.
and renaming ALIGNED_POINTER() to _ALIGNED_POINTER() plus the following
hacks for i386's:
- define _ALIGNED_POINTER() if it is not already defined. Most non-i386
arches define it <machine/param.h> define it in <machine/param.h>,
although none actually used it in the kernel.
- define ksym_start and ksym_end. Most non-i386 arches still define and
initialize these in machdep.c although they didn't used them. Here is
a better place to define them but not to initialize them.
to control the mapping of things like the ACPI and APM into memory.
The problem is that starting X changes these values, so if something
was using the bits of BIOS mapped into memory (say ACPI or APM),
then next time they access this memory the machine would hang.
This patch refuse to change MTRR values it doesn't understand,
unless a new "force" option is given. This means X doesn't change
them by accident but someone can override that if they really want
to.

Don't set __LONG_LONG_SUPPORTED for gcc-1. I didn't check exactly
when gcc started to support long long, but it was in the version
of gcc in FreeBSD-1.0 (gcc-2.4.5).
Other C99 features should be ifdefed similarly, but the ifdefs for
old versions of gcc will be more complicated since the features
weren't in all versions of gcc-2.

Include <sys/mutex.h> and its prerequisite <sys/lock.h> instead of
depending on namespace pollution in <sys/buf.h>. Only do this in the
__FreeBSD_version > 500000 case although the __FreeBSD_version < 500000
case has already rotted.
functions. We add pnpinfo, locationinfo, devflags (the newbus flags
on the device), flags (the flags that device_get_flags returns) and
state to the list of things we return.
pnpinfo and locationinfo are place holders at the moment that will be
filled in by the device's parent (optionally). Userland programs will
likely use this information from time to time and take appropriate
actions.
Improvements to devinfo to follow.

This case only occurred when setugidsafety() needed to close unsafe files.

v_tag is now const char * and should only be used for debugging.
Additionally:
1. All users of VT_NTS now check vfsconf->vf_type VFCF_NETWORK
2. The user of VT_PROCFS now checks for the new flag VV_PROCDEP, which
is propagated by pseudofs to all child vnodes if the fs sets PFS_PROCDEP.

I wish that the C language contained this as part of struct definintions,
but failing that, I would settle for an agreed upon set of functions for
packing/unpacking integers in various sizes from byte-streams which may
have unfriendly alignment.
This really belongs in <sys/endian.h> I guess.
