in r7 and use ip to store the old version of r7 as it is not guaranteed to
be kept when calling a subroutine. The kernel will preserve the register
across system calls.
- Simplify diagnostic messages.
- Adopt lowercase first letters to make the messages
more canonical.

Make umass return an error code if SCSI sense retrieval request
has failed. Make sure scsi_error_action honors SF_NO_RETRY and
SF_NO_RECOVERY in all cases, even if it cannot parse sense bytes.

interrupt counts and names, by making the names into an array of fixed-length
strings that can be directly indexed. This eliminates extra memory accesses
on every interrupt to increment the counts.
As a side effect, it also fixes a bug that would corrupt the names data
if a name was longer than MAXCOMLEN, which led to incorrect vmstat -i output.

The threaded rtld lock implementation is faster even in the single-threaded
case because it postpones signal handlers via THR_CRITICAL_ENTER and
THR_CRITICAL_LEAVE instead of calling sigprocmask(2).
As a result, exception handling becomes faster in single-threaded
applications linked with libthr.

to the old one's nfs.nfsrv.async.
Please note that by enabling this option (default is disabled), the system
could potentionally have silent data corruption if the server crashes
before write is committed to non-volatile storage, as the client side have
no way to tell if the data is already written.

two upcoming features:
semi-transparent mode:
when a device is opened in this mode, the
user program will be able to mark slots that must be forwarded
to the "other" side (i.e. from NIC to host stack, or viceversa),
and the forwarding will occur automatically at the next netmap syscall.
This saves the need to open another file descriptor and do
the forwarding manually.
direct-forwarding mode:
when operating with a VALE port, the user can specify in the slot
the actual destination port, overriding the forwarding decision
made by a lookup of the destination MAC. This can be useful to
implement packet dispatchers.
No API changes will be introduced.
No new functionality in this patch yet.
CPUs exhibit bad behavior if this is done (Intel Errata AAJ3, hangs on
Pentium-M, and trashing of the local APIC registers on a VIA C7). The
local APIC is implicitly mapped UC already via MTRRs, so the clflush isn't
necessary anyway.

tunable_mbinit() where it is next to where it is used later.
Change the sysinit level of tunable_mbinit() from SI_SUB_TUNABLES
to SI_SUB_KMEM after the VM is running. This allows to use better
methods to determine the effectively available physical and virtual
memory available to the kernel.
Update comments.
In a second step it can be merged into mbuf_init().
a process has an auditid/preselection masks specified, and

refactor the link section of distrib-dirs to alwasy install to a full
path (the link contents remain relative as they should).
Eliminate the use of the "rm -r[f] <foo>; ln -s <bar> <foo>" pattern in
favor of "ln -sf <bar> <foo>". None of these links could be directories
on a system installed in the last decade.
