Regression introduced in r343629 when malloc result was renamed from spa to
spa_mapping and the 'spa' name was instead used to iterate a table, but the
free() target was not updated.

GCC uses "dynamic" TLS models when -fpic or -fPIC is explicitly
specified on the command line (which is only true for shared libraries).
It uses "static" (or "exec") TLS models otherwise. In particular, GCC
does _not_ use dynamic TLS models when PIC is implicitly enabled (which
it is on MIPS), only if a PIC flag is explicitly provided.
llvm uses "dynamic" TLS models if PIC is enabled either via a PIC flag
or if it is implicily enabled (as on MIPS64). This means that llvm on
MIPS64 always uses "dynamic" TLS models. However, dynamic TLS models
do not work for static binaries and libraries as the __tls_get_addr
function they invoke is only defined in rtld.

Various bits in usr.bin/clang/* will fail to compile without -mxgot due to
truncated relocations. -mxgot entails a speed penalty, but I suspect we
don't care as much about compiler performance in 32-bit mips land.

Provide *cmpset_{8,16} as wrappers around atomic_fcmpset_32. Initial users
will be mips and sparc64, and perhaps parts of powerpc.
This are not for general consumption; machine/atomic.h should include this
header as needed to provide atomic_{,f}cmpset_{8,16} and machine/atomic.h
should provide acq_ and rel_ variants.

The mountpoint may not have defined an iosize parameter, so an attempt
to configure readahead on a device file can lead to a divide-by-zero
crash.
The sequential heuristic is not applied to I/O to or from device files,
and posix_fadvise(2) returns an error when v_type != VREG, so perform
the same check here.

The debug level generally just controls verbosity of libusb for debugging
libusb devices/usage. We allow the environment to set the debug level
independent of the application, but the application will always override
this if it explicitly sets the debug level.
Changing the environment is easy, but patching the software to change the
debug level isn't necessarily easy or possible. Further, there's this
write-only debug_fixed variable that would seem to imply that the debug
level should be fixed, but it isn't currently used. Change the logic to use
strtol() so we can detect real 0 vs. conversion failure, then honor
debug_fixed in libusb_set_debug.

For ll/sc architectures, atomic(9) allows failure modes where *old == val
due to write failure and callers should compensate for this. Do not retry on
failure, just leave 0 in ret and fail the operation if we couldn't sc it.
This lets the caller determine if it should retry or not.

Before attempting to initialize the command interface we must wait till
the fw_initializing bit is clear.
If we fail to meet this condition the hardware will drop our
configuration, specifically the descriptors page address. This scenario
can happen when the firmware is still executing an FLR flow and did not
finish yet so the driver needs to wait for that to finish.
