It was implemented for single byte locales only in any case.
2) Reduce [Cc]flag loop to WCHAR_MAX, WINT_MAX here includes WEOF which is
not a character.
3) Optimize [Cc]flag case: don't repeatedly add the last character of
string2 to squeeze cset when string2 reach its EOS state.
4) Reflect in the manpage that [=equiv=] is implemented for single
byte locales only.
on arm64 and all SoCs using the old FIFO register location are 32-bit only,
so unconditionally use the new location for arm64.

By definition (enum __drm_capabilities), cases other than CAP_SYS_ADMIN
aren't possible. Add in a KASSERT safety belt and return false in
!INVARIANTS case if an invalid value is passed in, as it would be a
programmer error.
This fixes a -Wreturn-type error with gcc 5.3.0.

If tf_trapno contains garbage which appears to be equal to T_NMI,
e.g. due to thread previously entered kernel due to NMI, doreti
sequence skips ast, and does so until a trap or hardware interrupt
occur.
The visible effects of the issue are quite confusing. First, signals
delivery is postponed in observable ways. In particular, the
guarantee that unblocked async signals queue is flushed before a
return from syscall, is broken. Second, if there are pending signals,
all interruptible sleeps of the stuck thread are aborted immediately.
Since modern CPUs are relatively fast and tickless kernel generates
low interrupt rate, the faulty condition might exist for long time (in
an application time scale).

if vnode is VMIO. For VMIO vnodes, set BO_DEAD in vm_object_terminate().
The vnode_destroy_object(), when calling into vm_object_terminate(),
must be able to flush buffers. BO_DEAD purpose is to quickly destroy
buffers on write when the underlying vnode is not operable any more
(one example is the devfs node after geom is gone). Setting BO_DEAD
for reclaiming vnode before object is terminated is premature, and
results in unability to flush buffers with live SU dependencies from
vinvalbuf() in vm_object_terminate().

Similar to r300836, r301800, and r302550, cl and ct will always
be non-NULL as they're allocated using the mem_alloc routines,
which always use `malloc(..., M_WAITOK)`.

`malloc(..., M_WAITOK)`.
Deobfuscating the cleanup path fixes a leak where if cl was NULL and
cu was not, cu would not be free'd, and also removes a duplicate test for
cl not being NULL.
