XXX. Unlike POSIX, Linux in case when the invalid seconds value specified
always return 0, so in that case Linux does not return proper remining time.

Add the ability to use filters that match on PF/VF (aka "VNIC id") while
here. This is mutually exclusive with filtering on outer VLAN tag with
Q-in-Q.

- Handle the case where no DOF helper is provided. This occurs with the
currently-unused DTRACEHIOC_ADD ioctl.
- Fix some checks that prevented the loading DOF in the (non-default)
lazyload mode.
Upstream, tracepoints are protected by per-CPU mutexes. An unlinked
tracepoint may be freed once all the tracepoint mutexes have been acquired
and released - this is done in fasttrap_mod_barrier(). This mechanism was
not properly ported: in some places, the proc lock is used in place of a
tracepoint lock, and in others the locking is omitted entirely. This change
implements tracepoint locking with an rmlock, where the read lock is used
in fasttrap probe context. As a side effect, this fixes a recursion on the
proc lock when the raise action is used from a userland probe.

Move the code that reads all the parameters to t4_init_sge_params in the
shared code. Use these per-adapter values instead of globals.

Further to r240152 (i386) and r240178 (amd64), hide the .cerror symbol
so that it is not exported if symbol versioning is not in use. Without
this change WITHOUT_SYMVER libc contains .text relocations for .cerror,
as described in LLVM PR 26813 (http://llvm.org/pr26813).
This is a no-op for the regular build as the symbol version script
already controls .cerror visibility.

Code may still be executing from the wrappers at unload time and thus is
not generally safe to unload. Converting the wrappers to use
EVENTHANDLER(9) will allow this to safely drain on active threads in
hooks. More work on EVENTHANDLER(9) is needed first.

- Get the list of registers to read during a regdump from the shared
code instead of the OS specific code. This follows a similar move
internally. The shared code includes the list for T6.
- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register
dumps (and catch up with some updates to T4 and T5 register decode).

strlcpy(3) null terminates but does not zero-fill the buffer, so would
leave beind any portion of the previous volume label longer than the
new one.
Note that tunefs only allows -L args up to a length of MAXVOLLEN-1, so
the stored label will be null-terminated (whether or not required by
UFS).

pathes. With the change, the kernel at least boots even when module

stack is not compliant with RFC 7323, which requires that TCP stacks send
a timestamp option on all packets (except, optionally, RSTs) after the
session is established.
This patch adds that support. It also adds a TCP signature option to the
packet, if appropriate.
