There are bunch of reports that this check fails at least on Nuvoton
NCT6776 chips. I don't see why this check needed there, and Linux does
not have it either. So far this check only made watchdogd unstopable.

fopen(3) will return NULL in case it can't open the STREAM.
The malloc will return a pointer to the allocated memory if successful,
otherwise a NULL pointer is returned.
Also add an extra DEBUG1 to print out the error to open a file.

device memory mapped in the DMAP. This can only happen if it is within the
same 1G block of normal memory.

system. This uses the hints mechnanism. This mostly works today
because when there's no static hints (the default), this value can be
fetched from the hint. When there is a static hints file, the hint
passed from the boot loader to the kernel is ignored, but for the BIOS
case we're able to find it anyway. However, with UEFI, the fallback
doesn't work, so we get a panic instead.
Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to
generate the old values to allow for transitions. In addition, fall
back to the old method if the new method isn't present.
Add comments about all this.

The testcase always fails today due to how C11 7.6.1/2 is interpreted
with clang 3.8.0 when combined with "#pragma STDC FENV_ACCESS ON".
This testcase passes with clang <3.8.0 and gcc, so continue testing it
with those compiler combinations

The change in r284345 moved the creation of openpam_static_modules.o to
lib/libpam/static_modules but never managed to get them into libpam.a.
Move this logic to lib/libpam/static_libpam and have it create a static
library for libpam.a The main lib/libpam/libpam will only create a
shared library. No redundancy in compilation or installation exists
in this solution.
This avoids requiring a pass with -D_NO_LIBPAM_SO_YET.

names, it's a filesystem-like namespace, which allows jails to be
kept to their own space, but still allows the system / jail parent to
access a jail's IPC.

_string variants on top of this. This requires a change to the function
signature of ata_res_sbuf(). Its use in the tree seems to be very limited,
and the change makes it more consistent with the rest of the API.

doreti provides the common code path for returning from interrupt
andlers on x86. Exposing doreti as a global symbol allows kernel
modules to include low-level interrupt handlers instead of requiring
all low-level handlers to be statically compiled into the kernel.

For some reason firmware sends Port Database Changed notifications in case
of explicit login requests from the driver when target port is unavailabe.
Those notifications don't give driver any new information, but only cause
infinite scan loop.
2TB. The latter can be increased in 512GB chunks by adjusting the lower
address, however more work will be needed to increase the former.
There is still some work needed to only create a DMAP region for the RAM
address space as on ARM architectures all mappings should have the same
memory attributes, and these will be different for device and normal memory.

- Start actual playback when there is some prebuffered audio,

Now that we're decap'ing A-MPDU frame, the firmware is only giving us
PHY status information for the whole PPDU, rather than duplicatig it
per frame.
So, we fake it by maintaining the RSSI that we saw in the node struct
and reuse it.
This prevents us from getting some pretty garbage looking default RSSI
values, which shows up as RSSI values of like "3" or "4" when doing
active traffic.
Tested:
* RTL8188EU, STA mode
basis.
2. grcdump can be taken at failure points by invoking bxe_grc_dump() when

3. grcdump_done can be monitored by the user to retrieve the grcdump.
