- Multiple verbs API updates
- Support for RoCE, RDMA over ethernet
All hardware drivers depending on the common infiniband stack has been
updated aswell.

This port failed to gain traction and probably only a couple Wii consoles
ran FreeBSD all the way to single user mode with an md(4). IPC
support was never implemented, so it was impossible to use any peripheral
Any further development, if any, will happen at https://github.com/rpaulo/wii.

than force the latter for an installkernel, just create the directory

I discovered this while working on llvm/lld and realized export-dynamic
only supported --. Although upstream will eventually grow to support
both - and --, switch this in our build system, because GNU ld supports
both modes, and because there's some hope lld will become the default linker
for FreeBSD in the future.

in kernel config files..
put VERBOSE_SYSINIT in it's own option header so the one file,
init_main.c, can use it instead of requiring an entire kernel recompile
to change one file..
The C standard undefines behavior when signed integers overflow. The
compiler toolchain has become more adept at detecting this and taking
advantage of faster undefined behavior. At the current time this has the
unfortunate effect of the clock stopping after 24 days of uptime.
clang makes no distinction between -fwrapv and -fno-strict-overflow. gcc
does treat them differently but -fwrapv is mature in gcc and is the
behavior are actually expecting.

KVM clock shares the same data structures between the guest and the host
as Xen so it makes sense to just have a single copy of this code.

The motivation here is to eventually teach netisr and potentially
other networking subsystems a bit more about how RSS work queues / buckets
are configured so things have a hope of auto-configuring in the future.
* net/rss_config.[ch] takes care of the generic bits for doing
configuration, hash function selection, etc;
* topelitz.[ch] is now in net/ rather than netinet/;
* (and would be in libkern if it didn't directly include RSS_KEYSIZE;
that's a later thing to fix up.)
* netinet/in_rss.[ch] now just contains the IPv4 specific methods;
* and netinet/in6_rss.[ch] now just contains the IPv6 specific methods.
This should have no functional impact on anyone currently using
the RSS support.

code in sys/kern/kern_dump.c. Most dumpsys() implementations are nearly
identical and simply redefine a number of constants and helper subroutines;
a generic implementation will make it easier to implement features around
kernel core dumps. This change does not alter any minidump code and should
have no functional impact.

get the tail part of the path. We can now build kernels the
old-fashioned way on FreeBSD 9.x and 10.x on at least amd64 using
clang 3.3, 3.4 or gcc 4.2.1 (though with the latter you need
WITHOUT_MODULES="aesni vmm cxgbe" due to various issues with
gcc 4.2.1).
