possible option and script path in the place of argv[0] supplied to
execve(2). It is possible and valid for the substitution to be shorter
then the argv[0].
Avoid signed underflow in this case.

- If precision is 0, don't print period followed by no digits.
- If precision is 0 stop printing units as soon as possible
(eg. if we have three years and five days and precision is 0
print only 3y5d).
- If precision is not 0, print all units (eg. 3y0d0h0m0s.00).

values for resolved symbols relative to relocbase instead of sections
so detect this case and handle as appropriate, which allows using
kernel modules linked with affected versions of binutils. Actually I
think this is a bug in binutils but given that apparently nobody
complained for nearly six years and powerpc has basically the same
workaround I decided to put it in for the sparc64 kernel, too.
- Fix R_SPARC_HIX22 relocations. Apparently these are hardly ever used.
the ataahci(4) and atamarvell(4) drivers share it between the host and
the controller.
- Spell some zeros as BUS_DMA_WAITOK when used as bus_dmamem_alloc() flags.

coherent.
- Add some missing bus_dmamap_sync() calls. This includes putting such
calls before calling reply handlers instead of calling bus_dmamap_sync()
for the request queue from individual reply handlers as these handlers
generally read back updates by the controller.
Tested on amd64 and sparc64.

It defaults to -5 dBm for eeproms earlier than v21.
This apparently only applies to Merlin (AR9280) or later,
earlier 11n chipsets have a power table offset of 0.
All the code in ath9k which checks the power table offset
and takes it into account first ensures the chip is
Merlin or later.
The earlier way of doing debugging would evaluate the function parameters
before calling the HALDEBUG. In the case of detailed register debugging
would mean a -lot- of unneeded register IO and other stuff was going on.
This method evaluates the ath_hal_debug variable before the function
parameters are evaluated, drastically reducing the amount of overhead
enabling HAL debugging during compilation.
The reason for this is a bug at ktrops() where process dereferenced
without having a lock. This might cause a panic if ktrace was runned
with -p flag and the specified process exited between the dropping
a lock and writing sv_flags.
Since it is impossible to acquire sx lock while holding mtx switch
to use asynchronous enqueuerequest() instead of writerequest().
Rename ktr_getrequest_ne() to more understandable name [1].

it possible for the kernel to track login class the process is assigned to,
which is required for RCTL. This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

- everything related to LRO should be in #ifdef INET blocks
- reorder sge_iq's fields so that the most frequently used are all together
- pull all rx code into t4_intr_data directly
- let go of the ingress queue lock when passing up data
- refill the freelist only if it is short of at least 32 buffers
