e3649d5a2f Modify the return value for nfscl_mustflush() from boolean_t,
which I mistakenly thought was correct w.r.t. style(9), back
to int and add the checks for != 0. This is just a stylistic
modification.

1d7fe4b515 Update the "desiredvnodes" calculation. In particular, make the part of
the calculation that is based on the kernel's heap size more conservative.
Hopefully, this will eliminate the need for MAXVNODES_MAX, but for the
time being set MAXVNODES_MAX to a large value.

better use of cache lines by placing it before pcb_save (now pcb_user_save),

a2d2c83668 - Merge savectx2() with savectx() and struct xpcb with struct pcb. [1]
savectx() is only used for panic dump (dumppcb) and kdb (stoppcbs).  Thus,
saving additional information does not hurt and it may be even beneficial.
Unfortunately, struct pcb has grown larger to accommodate more data.
Move 512-byte long pcb_user_save to the end of struct pcb while I am here.
- savectx() now saves FPU state unconditionally and copy it to the PCB of
FPU thread if necessary.  This gives panic dump and kdb a chance to take
a look at the current FPU state even if the FPU is "supposedly" not used.
- Resuming CPU now unconditionally reinitializes FPU.  If the saved FPU
state was irrelevant, it could be in an unknown state.

19291ab3de Document the mandatory argument to the arptimer() and
nd6_llinfo_timer() functions with a KASSERT().
Note: there is no need to return after panic.

In the legacy IP case, only assign the arg after the check,
in the IPv6 case, remove the extra checks for the table and
interface as they have to be there unless we freed and forgot
to cancel the timer.  It doesn't matter anyway as we would
panic on the NULL pointer deref immediately and the bug is
elsewhere.
This unifies the code of both address families to some extend.

28a53f037a Fix a bug in syncache where the initial CWND for new incoming connections
was limited to one segment under the faulty assumption of a retransmit.
Due to this the opportunity to initialize the increased congestion window
according to RFC3390 was missed.

Support for RFC3465 introduced in r187289 uncovered the bug as the ACK
to SYN/ACK no longer caused snd_cwnd increase by MSS (actually, this
increase shouldn't happen as it's explicitly forbidden by RFC3390, but
it's another issue).  Snd_cwnd remains really small (1*MSS + 1) and this
causes really bad interaction with delayed acks on other side.

The variable name sc_rxmits is a bit misleading as it counts all transmits,
not just retransmits.
