- Re-introduce "device ixgbe" option for kernel configs. This allows
users to continue using existing kernel configurations, while still
letting if_ix and if_ixv exist to allow ifconfig magic to work.
Though the amd64 GENERIC config has "device ix" and "device ixv" instead of
"device ixgbe".
This is achieved by making the if_ixgbe module a stub that depends
on if_ix and if_ixv.
- Replace if_baudrate assignment with if_initbaudrate() call.
Thanks to jhb@ for the stub module suggestion and pointing out the if_baudrate
error.

Ensure that the static structs emitted by the MODULE_DEPEND() and
MODULE_VERSION() macros don't end up as .comm symbols, when all the
version fields are zero.
Normally, such symbols will end up in .bss, but for kernel module
version objects, this can lead to "garbage" version numbers.
Fix this by instructing the compiler to always put these structs in the
.data segment instead.

Limit the number of cylinder groups that will be searched when
trying to build a cluster. The limit is tunable using the sysctl
vfs.ffs.maxclustersearch. The current limit is 10 cylinder groups
per block allocation. It was previously limited to the number of
cylinder groups in the filesystem per block allocation. When there
were no clusters of the needed size left, it repeatedly searched
the whole filesystem for a non-existent cluster on every block
allocation. The result was very slow filesystem allocation with
100% CPU utilization. The old behavior can be had by setting
vfs.ffs.maxclustersearch to a huge number (1,000,000).
This change affects only the layout policy routines so is not able
to interfere with the integrity of the filesystem.

Don't free mbufs when stopping an interface in netmap mode.
Currently if you ifconfig down a vtnet interface while it is being used
via netmap, the kernel panics due to trying to treat the cookie values
in the virtio rings as mbufs to be freed. When netmap is enabled, these
cookie values are pointers to something else.
Note that other netmap-aware drivers don't seem to need this as they
store the mbuf pointers in the software rings that mirror the hardware
descriptor rings, and since netmap doesn't touch those, the software
state always has NULL mbuf pointers causing the loops to free mbufs to
not do anything. However, vtnet reuses the same state area for both
netmap and non-netmap mode, so it needs to explicitly avoid looking at
the rings and treating the cookie values as mbufs if netmap is
enabled.

Fix an off-by-one error by adding proper range checks when parsing the

MFC r283163:

r283162.
Fixup to the kern_psignal manpage
r283105 misspelled kern_psignal as kernel_psignal in one occurrence, and
added trailing whitespace.
While here, change 'call' to the more standard 'function', and say why
the name was changed (taken from the commit message for r225617).
Use mkimg(1) to create the i386 memstick images, similar to
how is done for amd64. The exception here is there is no

Add a new file, Makefile.mirrors, which is intended to replace
a 474-line kludge of a shell script to pre-create the directory
hierarchy on ftp-master.
This is not in any way connected to the build, and there is no
intention to do so. This only intent here is to try to make
things a little bit easier.
Always use the 'make install' directory as the source for images.
For RE purposes, we use the default (/R within the chroot), so
this helps avoid copying files multiple times and xz(1)-compressing
additional times when not needed.
Fix staging virtual machine images for ftp propagation.
This Makefile is not for general consumption.

Do not set preload_addr_relocate for ARM.

Move ubldr text section to the start of the output file, so that when you

Use OF_getencprop over OF_getprop and fdt32_to_cpu. The latter may give

Remove the extra copy of uart_fdt_get_clock and uart_fdt_get_shift. While
here also use OF_getencprop in uart_fdt_get_clock.
Move uart_fdt_get_clock and uart_fdt_get_shift to uart_bus_fdt.c, we may
not build uart_cpu_fdt.c in all configs.
Fix uart_fdt_get_clock. It should have been using the cell variable passed
in, not value on the stack.
Present implementation of large sync writes is too strict and so can be
quite slow. Instead of doing that, execute large async write in chunks,
syncing each chunk separately.
It would be good to fix large sync writes too, but I leave it to somebody
with more skills in this area.
sfxge: relax assertion to allow RST flag in TSO packets
Kernel under stress load, mixed MC reboot and sfupdate really
generates TSO packet with RST flag.
It will generate many TCP packets with RST flag set.
May be RST flag should be set in the last segment only, but it could be
dropped. So, it is safer to keep the flag in all packets to be sure that
connection is reset.

When a netmap process terminates without the full set of buffers it
was granted via rings and ni_bufs_list_head represented in those rings
and lists (e.g., via SIGKILL), those buffers are no longer available
for subsequent users for the lifetime of the system. To mitigate this
resource leak, reset the allocator state when the last ref to that
allocator is released.
Note that this only recovers leaked resources for an allocator when
there are no longer any users of that allocator, so there remain
circumstances in which leaked allocator resources may not ever be
recovered - consider a set of multiple netmap processes that are all
using the same allocator (say, the global allocator) where members of
that set may be killed and restarted over time but at any given point
there is one member of that set running.
