option to try to change without also changing source code. [1]
Change default cache line size on ia64, sparc64, and sun4v to 128
bytes, as this was what rtld-elf was already using on those
platforms. [2]

stability, check for gw to be set before adding the flag and the address
to the routing message.
r186308, backed out in r191305, already tried to do that, and in addition
ignore AF_LINK types of gateway addresses to work around a problem that
r167797 had introduced on the kernel side always setting RTF_GATEWAY if a
gateway address was passed into the kernel.
The proper solution for this is still under discussion so I am hesitant to
re-add the special AF_LINK treatment for now.

in case of AF_LINK, which the kernel still returns for an RTAX_GATEWAY
as an empty sockaddr_dl in the classic tun<n> case.
Copying the address into the message payload, but not the RTA_GATEWAY
flag results in rt_xaddrs() in the kernel tripping over that and parsing
the next attribute set with a flag, i.e. RTA_NETMASK, with the gateway
address, resulting in bogus route entry.

Introduce a new flag RL_FLAG_AUTOPAD to mark automatic padding
feature of controller and set it for RTL8139C+ and controllers that
use new descriptor format. This fixes watchdog timeouts seen on
RTL8139C+.

Introduce pmap_try_insert_pv_entry(), a function that conditionally
creates a pv entry if the number of entries is below the high water mark
for pv entries.
Introduce pmap_enter_quick_locked() and use it to reimplement
pmap_enter_object(). The old implementation was broken. For example,
it could block while holding a mutex lock.
Change pmap_enter_quick_locked() to fail rather than wait if it is
unable to allocate a page table page. This prevents a race between
pmap_enter_object() and the page daemon. Specifically, an inactive
page that is a successor to the page that was given to
pmap_enter_quick_locked() might become a cache page while
pmap_enter_quick_locked() waits and later pmap_enter_object() maps
the cache page violating the invariant that cache pages are never
mapped. Similarly, change
pmap_enter_quick_locked() to call pmap_try_insert_pv_entry() rather
than pmap_insert_entry(). Generally speaking,
pmap_enter_quick_locked() is used to create speculative mappings. So,
it should not try hard to allocate memory if free memory is scarce.

OpenBSM 1.1
- Change auditon(2) parameters and data structures to be 32/64-bit architecture
independent. Add more information to man page about auditon(2) parameters.
- Add wrapper functions for auditon(2) to use legacy commands when the new
commands are not supported.
- Add default for 'expire-after' in audit_control to expire trail files when
the audit directory is more than 10 megabytes ('10M').
- Interface to convert between local and BSM fcntl(2) command values has been
added: au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
definitions of constants in audit_fcntl.h.
- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
generated by audit_submit(3) were improperly encoded has been fixed.
- Fix example in audit_submit(3) man page. Also, make it clear that we want
the audit ID as the argument.
- A new audit event class 'aa', for post-login authentication and
authorization events, has been added.

- Add and use mapping of fcntl(2) commands to new BSM constant space.
- Adopt (int) rather than (long) arguments to a number of auditon(2)
commands, as has happened in Solaris, and add compatibility code to
handle the old comments.
Note that BSM_PF_IEEE80211 is partially but not fully removed, as the
userspace OpenBSM 1.1alpha5 code still depends on it. Once userspace
is updated, I'll GCC the kernel constant.

Glibc does not use this operation since 2.3.3 version (Jun 2004),
as it is racy and replaced by FUTEX_CMP_REQUEUE operation.
Glibc versions prior to 2.3.3 fall back to FUTEX_WAKE when
FUTEX_REQUEUE returned EINVAL.
Any application directly using FUTEX_REQUEUE without return
value checking are definitely broken.
Limit quantity of messages per process about unsupported
operation.

Without this fix, some programs would occasionally get SIGTRAP instead

Start relookup instead. Rename is supposed to change '..' reference
atomically, so transient failures introduced by r191137 are wrong.
While rearranging the code to allow lookup restart in ufs_lookup(),
remove the comment that only distracts the reader.

a non-zero busy count.
(The prohibition on mapping pages for read access when they have a non-
zero busy count originated in revision 1.202 of i386/i386/pmap.c when
this code was a part of the pmap.)

runtime with 'sysctl net.inet.flowtable.enable=1'.
- Embedded users can remove it entirely from the kernel by adding 'nooption FLOWTABLE' to
their kernel config files.
- A minimal hookup will be added to ip_output in a subsequent commit. I would like to see
more review before bringing in changes that require more churn.
