(This code is as yet untested; to come after man page is written.)
This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC
instructions. The user-mode interface is via a subdevice of mem.c;
there is also a kernel-size interface which might be used to aid
profiling.
Move ipip_input() and rsvp_input() prototypes to ip_var.h
Remove unused prototype for rip_ip_input() from ip_var.h
Remove unused variable *opts from rip_output()

When initiating a write, ccdbuffer() returns two "struct ccdbuf *"s
linked together by the cb_mirror field. "cb_pflags &
CCDPF_MIRROR_DONE" is set to 0 on both of them.
When a component returns to ccdiodone(), it checks if "cb_pflags &
CCDPF_MIRROR_DONE" is set or not. If not, it sets the partner's
flag and returns. If it is, it means its partner has already
returned, so it will go to the regular cleanup (which is in the
fallthrough code).
There should be no performance or functionality changes unless the
higher-level scsi driver does something with the resid value. The change
is purely aesthetical and prepares us for the parity implementation.
recent libdisk changes. (sysinstall is guilty of using `private' in
quite more places, but since this ain't in library code, it's not that
important.)
Whenever possible, better not use C++ reserved words...
- add __BEGIN_DECLS and __END_DECLS,
- add a bunch of ``const'' qualifiers all over the place,
- rename the `private' struct member into `private_data' to avoid the
clash with the C++ keyword.
/var/run resides on an NFS filesystem (flock() always returns 0 in
this case, so we falsely assume that ypbind is dead and bail out).
Settle instead for better failure checking when using clnttcp_create()
and clnt_call() to interact with ypbind. We still try to flock()
/var/yp/binding/$DOMAINNAME.2, but if this doesn't work, we drop into
the code that retrieves the binding information from ypbind directly.
If that also fails, then we're toast. On NFS filesystems, this means
we'll be ignoring the binding file for no reason and always talking to
ypbind even though we don't have to, but at least things will work.
(I could just replace the flock(/var/run/ypbind.lock) check with
an RPC call to ypbind's NULLPROC procedure, but if the flock() of
the binding file doesn't pan out we're going to try to talk to
ypbind later anyway. *sigh* Is NFS file locking ever going to work?)
broken. The translation from network number to ASCII string was not
working correctly (you would sometimes get things like 0.244.0.0 instead
of 244.0.0).
Also copied results of yp_match() to a static buffer for consistency
with gethostbynis.c.
Note: _getnetbynisaddr() chops off trailing .0's, i.e. 244.0.0 is
truncated to 244. By contrast, getnetbyht.c code (for local /etc/networks
lookups) leaves the traling .0's in place. This means that the NIS
and local file lookups will match different things when looking up the
same network number. I'm not sure which is the correct behavior. (I
think the DNS lookup code tries all combinations -- should the NIS
and local host lookup routines do that too?)
