callers. This also fixes a problem when the prison call could set
the inp->in6p_laddr (laddr) and a following priv_check_cred() call
would return an error and will allow us to merge the IPv4 and IPv6
implementation.

even after dropping the reference and unlocking. Previously we
have dereferenced a NULL pointer (after r121765).
Simply unlocking after the block does not work either because of
lock ordering (see r121765) and in addition we would still hold
a pointer to something that might be gone by the time we access it.
Thus take a copy of the value rather than just caching the pointer.

Add systrace_linux32 and systrace_freebsd32 modules which provide
support for tracing compat system calls in addition to native system
call tracing provided by systrace module.
Provided that all the systrace modules are loaded now you can select
what syscalls to trace in the following manner:
syscall::xxx:yyy - work on all system calls that match the specification
syscall:freebsd:xxx:yyy - only native system calls
syscall:linux32:xxx:yyy - linux32 compat system calls
syscall:freebsd32:xxx:yyy - freebsd32 compat system calls on amd64

also does this for sound drivers it's probably not necessary for all
combinations of controllers and drivers. However, given that our sound
drivers completely lack bus_dmamap_sync(9) calls this at least serves
as a workaround when enabling use of the IOMMU streaming buffers on
sparc64 and generally for arm and mips.

- Emitt an error when encountering an unsupported and in case of the
kernel also for unaligned relocations.
- Fix R_SPARC_LOX10 relocations. Apparently these are hardly ever used.
- Add the _RF_X committed in r212998 also to the tables in the sparc64
reloc.c in order reduce differences between the kernel and the userland
source. This results in no functional change though.
- Fix further inconsistencies in the abbreviations of the names of the
relocations.
- Further whitespace fixes.

This is a minor cosmetic change - the users are more likely to want to
increase (rather than decrease) default kernel stack size,
which is already 4 pages on amd64.

Linux ath9k.
The ath9k ar9002_hw_init_cal() isn't entirely clear about what
is supposed to be called for what chipsets, so I'm ignoring the
rest of it and just porting the AR9285 init cal path as-is and
leaving the rest alone. Subsequent commits may also tidy up the
Merlin (AR9285) and other chipset support.

The ath9k driver has a unified boundary/pdadc function, whereas
ours is split into two (one for each EEPROM type.) This is why
the AR9280 check is done here where we could safely assume it'll
always be AR9280 or later.
this is incorrect for Kite (AR9285) and any future chipsets that
override the EEPROM related routines.
It meant that a direct call to set the TX power would call the v14 EEPROM
AR5416/AR9280 calibration routines, rather than the v4k EEPROM routines
for the AR9285. It thus read the incorrect values from the EEPROM and
programmed garbage PDADC and TX power values into the hardware.
adjust the IEEE80211_HTRATE_MAXSIZE constant, only MCS0 - 76 are valid
the other bits in the mcsset IE (77 - 127) are either reserved or used
for TX parameters.
o bunch of variables are turned into uint8_t
o initial setting of namep[] in lookup() is removed
as it's only overwritten a few lines down
o kname is explicitly initialized in main() as BSS
in boot2 is not zeroed
o the setting and reading of "fmt" in load() is removed
o buf in printf() is made static to save space

It looks like these apply in both open and closed loop TX power control,
but the only merlin boards i have either have OL -or- a non-default power
offset, not both.
to both make things clearer, and to make it easier to write userland
code which pulls in these definitions without needing to pull in the
rest of the HAL.
This stuff should be deprecated at some point in the future once
the net80211 regulatory domain support encapsulates all of the
defintions here.
This is something bus clock related from what I can gather. It is needed for
the AR9220 based Ubiquiti SR71-12 and SR71-15 Mini-PCI NICs.
(Note: those NICs don't work right now because of earlier changes to handle
power table offset correctly. That'll be resolved in a follow-up commit.)
