24, and 32 bit modes. To use that, syscons(4) must be built with
the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a.
vesa.ko) must be either loaded, or be compiled into the kernel.
Do not return EINVAL when the mouse state is changed to what it already is,
which seems to cause problems when you have two mice attached, and
applications are not likely obtain useful information through the EINVAL
caused by showing the mouse pointer twice.
Teach vidcontrol(8) about mode names like MODE_<NUMBER>, where <NUMBER> is
the video mode number from the vidcontrol -i mode output. Also, revert the
video mode if something fails.

Only panic is fixed, module will be still listed in kldstat(8) output.
Not sure what is correct fix, because adding unloading code in case of
failure to linker_init_kernel_modules() doesn't work.
of having the kernel parse that line and add an entry to the argument list for
each 'separate word' it finds, have it add only one entry which holds all
the words found on that line. The old behavior is useful in some situations,
but it does not match the way any other operating system will parse that line.
This has been discussed in the thread "Bug in #! processing - One More Time"
on the freebsd-arch mailing list (starting back on Feb 24, 2005). The first
few messages in that thread provide the background in much detail.

on the their simply wrapping MPSAFE implementations of existing MPSAFE
system calls:
getfsstat()
lseek()
stat()
lstat()
truncate()
ftruncate()
statfs()
fstatfs()
Note that ogetdirentries() is not marked MPSAFE because it does not share
the MPSAFE implementation used for getdirentries(), and requires separate
locking to be implemented.
Note: len gets intialized to 0 for sap == NULL case only to
make compiler on amd64 happy. This has nothing todo with the
former uninitialized use of len in sap != NULL case.

- Teach the i386 and pc98 loaders to honor multiple console requests from
their respective boot2 binaries so that the same console(s) are used in
both boot2 and the loader.
- Since the kernel doesn't support multiple consoles, whichever console is
listed first is treated as the "primary" console and is passed to the
kernel in the boot_howto flags.

that protects socket and receive socket buffer state, and a second
mutex to protect send socket buffer state. In some places, the
mutex shared between the socket and receive socket buffer will be
acquired twice, once by each layer, resulting in some
inconsistency, but providing the abstraction benefit of being able
to more easily separate the two mutexes in the future if desired.
When transitioning a socket to the SS_ISDISCONNECTING or
SS_ISDISCONNECTED states, grab the socket/receive socket buffer lock
once rather than grabbing it as the socket lock, modifying socket
state, then grabbing a second time as the receive lock in order to
modify the socket buffer state to indicate no further data can be
read. This change is believed to close a race between the change in
socket state and the change in socket buffer state, which for a
remotely initiated close on a UNIX domain socket, resulted in
soreceive() returning ENOTCONN rather than an EOF condition.
A similar race still exists in the case of send, however, and is
harder to fix as the socket and send socket buffer mutexes are not
the same, and we would like to avoid holding combinations of socket
mutexes over sb_upcall until we've finished clarifying the locking
protocol for upcalls.
This change has the side affect of reducing the number of mutex
operations to initiate disconnect or perform disconnect on a
socket by two.

Suffering: great
long (and unsigned long long) to long double conversions.
- Add a parameter that specifies the position of the sign bit to the _QP_TTOQ
macro, previously it always looked at bit 31. Pass a negative number to
disable sign inspection for unsigned types. This fixes _Qp_xtoq(),
_Qp_uitoq() and _Qp_uxtoq().
- In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to
decide whether we're doing a conversion from an unsigned type. If so, don't
negate the mantissa if the integer exceeds the biggest signed number.
