56842578ac Check that there is memory range support before attempting to perform such
an operation, as a kernel client may not have previously checked the CPU
type (it may not be able to).

Also correct the function declaration style for the mem_range functions to
match the rest of this file (oops).

216936ca6d Make bdev userland access work like cdev userland access unless
the highly non-recommended option ALLOW_BDEV_ACCESS is used.

(bdev access is evil because you don't get write errors reported.)

Use the specfs routines rather having cloned copies in devfs.

421ba20de2 Add sysctl variables for the Linuxulator. These reside under `compat.linux' as
discussed on current.

The following variables are defined (for now):

    osname (defaults to "Linux")
        Allow users to change the name of the OS as returned by uname(2),
        specially added for all those Linux Netscape users and statistics
        maniacs :-) We now have what we all wanted!

    osrelease (defaults to "2.2.5")
        Allow users to change the version of the OS as returned by uname(2).
        Since -current supports glibc2.1 now, change the default to 2.2.5
        (was 2.0.36).

    oss_version (defaults to 198144 [0x030600])
        This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I
        can commit now that we have the MIB. The default version number is the
        lowest version possible with the current 'encoding'.

A note about imprisoned processes (see jail(2)):
  These variables are copy-on-write (as suggested by phk). This means that
  imprisoned processes will use the system wide value unless it is written/set
  by the process. From that moment on, a copy local to the prison will be
  used.

A note about the implementation:
  I choose to add a single pointer to struct prison, because I didn't like the
  idea of changing struct prison every time I come up with a new variable. As
  a side effect, the extra storage is only needed when a variable is set from
  within the prison. This also minimizes kernel bloat when the Linuxulator is
  not used; both compiled in or as a module.

b9c4386c6d Use .p2align to ensure consistant a.out/elf alignment. I'd have used
SUPERALIGN_TEXT, but this is inline assembler and after cpp has run.

8858fe3aec It would help if things that MUST be 32 bit aligned were really 32 bit
aligned.  If I recall correctly, this is to ensure apic_imen can be
accessed in a single bus cycle.  Also, use TEXT_ALIGN rather than a
.align 2 (which means 2 byte align on ELF and 4 byte align on a.out)

09bd601964 Fix {g|s}etgroups semantics. We use cr_groups[0] to hold egid. This means that
egid will be twice in the set and that setting cr_groups[0] will change egid.
This is simply solved by ignoring cr_groups[0]. That is; linux_getgroups does
not return cr_groups[0] and linux_setgroups does not touch it.

663cbe4fc2 Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().
