filename passed in via the module loader functions in the GDB
"sharedlibrary" support structures. This isn't good, since the pointer
would become stale in almost every case (not the pre-loaded case, of
course).
Change this to malloc()ed copy of the string and finally fix the reason
that gdb -k's "sharedlibrary" command stopped working.

It didn't implement the proper /dev/fd functionality (which would be to
include in the directory listing /dev/fd/n if the process has fd n open)
anyway.
Anything needing access to /dev/fd/n where n > 2 can use the optional
fdescfs module, which implements this properly and does not cause any
trouble with devfs.

advantage of native calling.
just before the memory hole to 4 megs. Special case building exception.s
like locore.s, it needs to at the beginning so the branches out from the
trap table don't overflow.
Correct an off by one in our critical section handling.
SEQADDR always reads the next instruction to execute,
so we must subtract one from its value before making
comparisons with entries in the critical section table.
Print a few additional registers whenever we dump
card state.
Show the SCB_CONTROL and SCB_TAG values for all pending
SCBs in card SCB ram when dumping card state.
aic7xxx.seq:
Fix a bug introduced while optimizing the SDPTR path.
We would ack the SDPTR message twice on Ultra2 or better
chips if it occurred after all data had been transferred
for a transaction.
Change our workaround for the PCI2.1 retry bug on some
chips. Although the previous workaround was logically
correct, its faster method of draining the FIFO seemed
to occassionally confuse the FIFO state. We now drain
the FIFO at half the speed which avoids the problem.
aic7xxx_pci.c:
Chips with the PCI 2.1 retry bug can't handle a 16byte
cachesize. If the cachesize is set to 16bytes, drop
it to 0.
Although it can go higher, it is not safe to so do on arrays with many
members. Compromise by adding a tunable, "hw.aac.iosize_max" that can be
set at boottime. Also document in the aac(4) manpage.

can't blindly write zero into it to disable the card. We must
preserve this bit. This changes pcic_disable to only clear the bits
we know we need to clear on card disable, thus preserving the magic
bit for many TI bridges.
This appears to have fixed the problems that people are reporting
about the system failing to recognize cards being inserted or removed
(or both). Greg: This may fix your problem too :-).
interrupt handler from the upper half, etc. This fixes some serious stability
problems that we were seeing on our production server. These patches have
been tested for almost 6 months and are a highly recommended MFC candidate.

bind() call on IPv4 sockets:
Currently, if one tries to bind a socket using INADDR_LOOPBACK inside a
jail, it will fail because prison_ip() does not take this possibility
into account. On the other hand, when one tries to connect(), for
example, to localhost, prison_remote_ip() will silently convert
INADDR_LOOPBACK to the jail's IP address. Therefore, it is desirable to
make bind() to do this implicit conversion as well.
Apart from this, the patch also replaces 0x7f000001 in
prison_remote_ip() to a more correct INADDR_LOOPBACK.
This is a 4.4-RELEASE "during the freeze, thanks" MFC candidate.

and so special-casing was introduced to provide extra procfs privilege
to the kmem group. With the advent of non-setgid kmem ps, this code
is no longer required, and in fact, can is potentially harmful as it
allocates privilege to a gid that is increasingly less meaningful.
Knowledge of specific gid's in kernel is also generally bad precedent,
as the kernel security policy doesn't distinguish gid's specifically,
only uid 0.
This commit removes reference to kmem in procfs, both in terms of
access control decisions, and the applying of gid kmem to the
/proc/*/mem file, simplifying the associated code considerably.
Processes are still permitted to access the mem file based on
the debugging policy, so ps -e still works fine for normal
processes and use.
