__start_SECNAME and __stop_SECNAME symbols are automatically generated
by ld for orphan sections, i.e. those not explicitely referenced by a
linker script. The symbols are supposed to be placed correspondingly
at the start and the end of the section in output file. In some cases
__start_SECNAME may be placed at the address after the end of the
previous section (if any) and before the start the section. This
happens when following conditions are met:
1. the orphan section is found in more than one input file
2. the orphan section has different alignment requirements across input
files
3. the first instance of the section encountered doesn't have the
greatest alignment requirement
In these conditions resulting output section will be placed at address
after the end of the previous section aligned to the greatest alignment
requirement in the inputs, but __start_SECNAME will be placed at address
after the end of the previous section aligned to the alignment
requirement of the first input in which the section is encountered.
See commit message of r196118 for a concrete example of problems caused
by this bug.
The fix is to place __start_SECNAME inside the section and use ABSOLUTE
directive, rather than placing __start_SECNAME outside the section and
trying to guess address alignment.
This fix is in line with upstream binutils change/fix made between
versions 2.19 and 2.20 in revision of 1.307 ldlang.c.

This is a somewhat conservative version of the patch - more fine tuning may be
necessary.

a separate inline function. This further reduces duplicate code that didn't
have a good reason to stay as it was.
- Reorder the malloc of a pkt_node struct in the hook functions such that it
only occurs if we managed to find a usable tcpcb associated with the packet.
- Make the inp_locally_locked variable's type consistent with the prototype of
siftr_siftdata().

systems with PnP/ACPI not reporting i8254 timer. In some cases it can be
fatal, as i8254 can be the only available time counter hardware. From other
side we are now heavily depend on i8254 timer and till the last time it's
init/usage was completely hardcoded. So this change just restores previous
behavior in more regular fashion.
count on nfsv4rootfs_lock when dumping state, since these functions
are not called by nfsd threads. Without this reference count, it
is possible for an nfsd thread to acquire an exclusive lock on
nfsv4rootfs_lock while the dump is in progress and then change the
lists, potentially causing a crash.

changed to defer the setting of VN_LOCK_ASHARE() (which clears LK_NOSHARE
in the vnode lock's flags) until after they had determined if the vnode was
a FIFO. This occurs after the vnode has been inserted a VFS hash or some
similar table, so it is possible for another thread to find this vnode via
vget() on an i-node number and block on the vnode lock. If the lockmgr
interlock (vnode interlock for vnode locks) is not held when clearing the
LK_NOSHARE flag, then the lk_flags field can be clobbered. As a result
the thread blocked on the vnode lock may never get woken up. Fix this by
holding the vnode interlock while modifying the lock flags in this case.
