Document that sem_wait() can fail with [EINTR].
Programs often do not expect an [EINTR] return from sem_wait() and POSIX
only allows it if the signal was installed without SA_RESTART. The timeout
in sem_timedwait() is absolute so it can be restarted normally.
The old POSIX semaphore implementation did this correctly, unlike the new
umtx one.
Specific to 9-stable: UMTX_ABSTIME does not exist and therefore
sem_timedwait() is erroneously not restarted after a SA_RESTART signal
handler.
It may be desirable to avoid [EINTR] completely, which matches the pthread
functions and is explicitly permitted by POSIX. However, the kernel must
return [EINTR] at least for signals with SA_RESTART clear, otherwise pthread
cancellation will not abort a semaphore wait. In this commit, only restore
the 8.x behaviour which is also permitted by POSIX, as far as possible with
the ABI in 9-stable.

Pull in r178240 from upstream llvm trunk:
Section 24.2.2 of the C++ standard, [iterator.iterators], Table 106
requires that the return type of *r for all iterators r be reference,
where reference is defined in [iterator.requirements.general]/p11 as
iterator_traits<X>::reference, and X is the type of r.
But in CFG.h, the dereference operator of PredIterator and
SuccIterator return pointer, not reference.
Furthermore the nested type reference is value_type&, which is not
the type returned from operator*().
This patch simply makes the iterator::reference type value_type*,
which is what the operator*() returns, and then re-lables the return
type as reference.
From a functionality point of view, the only difference is that the
nested reference type is now value_type* instead of value_type&.
This enables building clang 3.2 with the newer version of libc++ that
was merged in r250514 (and which has stricter iterator requirements for
the vector member templates).
This is a direct commit to stable/9, since head has a complete import of
llvm/clang trunk, and there is no single commit to merge.

When an NFS unmount occurs, once vflush() writes the last dirty

It is possible that an nfsiod thread will try to check for an

setting the iodmount entries for the mount back to NULL while holding the
mutex in the unmount and checking the appropriate entry is non-NULL after
acquiring the mutex in the nfsiod thread.

Both NFS clients can deadlock when using the "rdirplus" mount

a buffer lock attempts to acquire a vnode lock on an entry in

is waiting on an nfsiod thread. This patch avoids the deadlock by disabling
readahead for this case, so the nfsiod threads never do readdirplus.
Since readaheads for directories need the directory offset cookie
from the previous read, they cannot normally happen in parallel.
As such, testing by jhb@ and myself didn't find any performance
degredation when this patch is applied. If there is a case where
this results in a significant performance degradation, mounting
without the "rdirplus" option can be done to re-enable readahead
