Being exported, AT_CLKTCK is returned by sysconf(_SC_CLK_TCK),
glibc falls back to the hard-coded CLK_TCK value when aux entry
is not present.
Glibc versions prior to 2.2.1 always use hard-coded CLK_TCK value.
For older applications/libc's which depends on hard-coded CLK_TCK
value user should set compat.linux.osrelease less than 2.4.0.

Use stathz if it is available, otherwise use hz.

- Just use #error when including <sys/ioctl.h> in the kernel. Code
hasn't used this header for years now and probably doesn't compile
anyway, because of -Werror.
- Get rid of struct ttysize, TIOCGSIZE and TIOCSSIZE. All code nowadays
use both TIOC[GS]SIZE and TIOC[GS]WINSZ. Because we have other popular
systems that don't implement the first, it's of little use to support
interfaces nowadays.
Credential might need to hang around longer than its parent and be used
outside of mnt_explock scope controlling netcred lifetime. Use separate
reference-counted ucred allocated separately instead.
While there, extend mnt_explock coverage in vfs_stdexpcheck and clean-up
some unused declarations in new NFS code.

At first I allowed ioctl_compat.h to be included, but it just returned
an empty file. I had to do this, to keep kdump happy. I really want to
raise a compiler error when including this header, so now it will just
throw an error if you don't set COMPAT_43TTY.
that vnode_pager_input_smlfs() zeroes the page, it should not mark the page
as valid until after the page is zeroed. Otherwise, the page could be
mapped for read access (e.g., by vm_map_pmap_enter()) before the page is
zeroed. Reviewed by: tegge
Eliminate gratuitous clearing of the page's dirty mask by
vnode_pager_input_smlfs(). Instead, assert that the page is clean.

Eliminate some blank lines.
Eliminate pointless calls to pmap_clear_modify() and vm_page_undirty() from
vnode_pager_input_old(). The page is not mapped. Therefore, it cannot have
any page table entries that are modified.
Eliminate an incorrect comment from vnode_pager_generic_getpages().

I really don't want any pieces of code to include ioctl_compat.h, so let
the ibcs2 and svr4 compat leave sgtty alone. If they want to support
sgtty, they should emulate it on top of termios, not sgtty.
The code has been marked with BURN_BRIDGES for a long time. ibcs2 and
svr4 are not really popular pieces of code anyway.
virtualized instances of hostname and domainname, as well as a new top-level
virtualization struct vimage, which holds pointers to struct vnet and struct
vprocg. Struct vprocg is likely to become replaced in the near future with
a new jail management API import.
As a consequence of this change, change struct ucred to point to a struct
vimage, instead of directly pointing to a vnet.
Merge vnet / vimage / ucred refcounting infrastructure from p4 / vimage
branch.
Permit kldload / kldunload operations to be executed only from the default
vimage context.
This change should have no functional impact on nooptions VIMAGE kernel
builds.
