so it can be easly compared to the hash calculated via file system.

According to POSIX, these two header files should be able to be included
by themselves, not depending on other headers. The <net/if.h> header
uses struct sockaddr when __BSD_VISIBLE=1, while <netinet/tcp.h> uses
integer datatypes (u_int32_t, u_short, etc).

ioctlname() to return a pointer to the name rather than print it. This did
not show up in testing because truss had its own prototype for ioctlname(),
so it would build fine and run fine as long as the program being traced did
not issue an ioctl.
Teach mkioctls to generate different versions of ioctlname() based on its
first command-line argument.

implement a deprecated FPU control interface in addition to the
standard one. To make this clearer, further deprecate ieeefp.h
by not declaring the function prototypes except on architectures
that implement them already.
Currently i386 and amd64 implement the ieeefp.h interface for
compatibility, and for fp[gs]etprec(), which doesn't exist on
most other hardware. Powerpc, sparc64, and ia64 partially implement
it and probably shouldn't, and other architectures don't implement it
at all.
working MI one. The MI one only needs to be overridden on machines
with non-IEEE754 arithmetic. (The last supported one was the VAX.)
It can also be overridden if someone comes up with a faster one that
actually passes the regression tests -- but this is harder than it sounds.
- Handle cases where exp(x) would overflow, but ccosh(x) ~= exp(x) / 2
shouldn't.
- Use the ccosh(x) ~= exp(x) / 2 approximation to simplify the calculation
when x is large.
Similarly for csinh(). Also fixed the return value of csinh(-Inf +- 0i).
exp(x) scaled down by some factor, and the challenge is doing this
accurately when exp(x) would overflow. This change replaces all of
the tricks we've been using with common __ldexp_exp() and
__ldexp_cexp() routines that handle all the scaling.
bde plans to improve on this further by moving the guts of exp() into
k_exp.c and handling the scaling in a more direct manner. But the
current approach is simple and adequate for now.

physical block size declared in bp may not always be what we want.
For example in case of gang block header physical block size declared
in bp is much larger than SPA_GANGBLOCKSIZE (512 bytes) and checksum
calculation failed. This bug could lead to accessing unallocated
memory and resets/failures during boot.

more easily catch unnoticed code paths.
This does not neccessarily improve locking in pfsync, it just tries
to avoid the panics reported.

pfsync also depends on pf to be initialized already so pf goes at
FIRST and the interfaces go at ANY.
Then the (VNET_)SYSINIT startups for pf stays at SI_SUB_PROTO_BEGIN
and for pfsync we move to the later SI_SUB_PROTO_IF.
This is not ideal either but at least an order that should work for
the moment and can be re-fined with the VIMAGE merge, once this will
actually work with more than one network stack.

This fixes the problem some people are seeing that state is removed when pf

With the addition of various GEOM layers some device names now exceed
this length, for example /dev/mirror/encrypted.elig.journal. This
change expands the field to 53 bytes which brings the /etc/dumpdates
lines to 80 characters. Exceeding 80 characters makes the /etc/dumpdates
file much less human readable. A test is added to dump so that it
verifies that the device name will fit in the 53 character field
failing the dump if it is too long.
This change has been checked to verify that its /etc/dumpdates file
is compatible with older versions of dump.

If we handle an interrupt just before the 'wait' and the interrupt
schedules some work, we need to skip the 'wait' call. The simple solution
of calling sched_runnable() with interrupts disabled immediately before
wait still leaves a window after the call and before 'wait' in which
the same issue can occur.
The solution implemented is to check the EPC in the interrupt handler, and
if it is in a region before the 'wait' call, to fix up the EPC to skip the
wait call.
