806202b507 - Unlike as in the PCI case, when attached to ACPI, Intel Bay Trail
and Braswell eMMC and SDXC controllers share the same IDs. Like in
  the PCI case, Braswell eMMC needs the SDHCI_QUIRK_DATA_TIMEOUT_1MHZ
  quirk (see r311794 for the corresponding change to the sdhci(4) PCI
  PCI front-end), though. However, due to the shared ACPI IDs, this
  is trickier to do.
- Intel Apollo Lake eMMC and SDXC controllers are affected by the
  APL18 ("Using 32-bit Addressing Mode With SD/eMMC Controller May
  Lead to Unpredictable System Behavior") silicon bug [1]. When this
  erratum hits, typically both SDHCI and XHCI controllers wedge.
  According to Intel, using ADMA2 with 64-bit addressing and 96-bit
  descriptors serves as a workaround. Until such times when sdhci(4)
  has ADMA2 support, flag DMA as broken for affected interfaces.
  This turns out to work around the problem, too, at the cost of
  performance.
- In the sdhci(4) ACPI front-end, probe the Intel Apollo Lake eMMC
  and SDXC controllers, too.

ead8d64aed Mark errf _Noreturn, and mark errf and warn __printflike
The _Noreturn attribute was added to placate Coverity and other static
analysis tools. The __printflike attribute was added to catch issues
with the calls related to printf(3) abuse.

- Modify the code to facilitate the __printflike attribute addition.
- Convert errf calls in to_mb(..) and to_mb_string(..) to warn(..) so
  the calls will return instead of exiting, as the code suggests it
  should.

947572b4ee Change the default uid/gid values for nobody/nogroup to 65534/65533.
The default values found in /etc/passwd and /etc/group are 65534, 65533.
In mountd.c, the defaults were -2, which was 65534 back when uid_t was 16bits.
Without this patch, a file created by root on an NFS exported volume without
the "-root=" export option will end up owned by uid 4**32 - 2.
When discussed on freebsd-current@, it seemed that users preferred the
values being changed to 65534/65533.
I have not added code to acquire these values from the databases, since
the mountd daemon might get "stuck" during startup waiting for a non-responsive
password database server.

396a0d4455 Do not wake up sleeping thread in reschedule_signals() if the signal
is blocked.  The spurious wakeup might result in spurious EINTR.

The reschedule_signals() function is called when the calling thread
has the signal mask changed.  For each newly blocked signal, we try to
find a thread which might have the signal not blocked.  If no such
thread exists, sigtd() returns random thread, which must not be waken
up.  I decided that re-checking, as suggested by PR submitter, is more
reasonable change than to change sigtd() interface, due to other uses
of sigtd().  signotify() already performs this check.

c048736782 [iwm] Adjust if_iwm_sta.h prototypes, don't pass iwm_node to rm_sta().
* Since a RUN -> INIT/SCAN transition seems to immediately destroy the
  ieee80211_node for the AP, we can't read the in_assoc value from there.
  Instead just directly pass that information via a boolean_t argument.

* Adds iwm_mvm_rm_sta_id() function, which just unconditionally removes
  the station from the firmware.

* The iwm_mvm_rm_sta() function shouldn't actually remove the station from
  firmware when we are still associated (i.e. during a RUN -> INIT/SCAN
  transition).

 * So when disassociating we will first call iwm_mvm_rm_sta() to drain the
   queues/fifos. Later during disassociation we will then use
   iwm_mvm_rm_sta_id() to actually remove the station.

* Removing the IWM_FH_RCSR_CHNL0_RX_CONFIG_SINGLE_FRAME_MSK flag allows

  frames) into a single RX buffer.

* Uses m_copym() to split up the receive buffers when multiple 80211
  frames are received in one RX buffer. The effect is basically the same
  as when using m_split(), but we want to keep the original mbuf around
  when calling iwm_mvm_rx_rx_mpdu() to make error handling a bit easier
  for now.

* Contains a small optimization to avoid the m_copym() when only a single
  80211 frame is received in one RX buffer (i.e. matching the existing
  behaviour).

0c46712ca1 Let ptracestop() suspend threads sleeping in an SBDRY section.
When a thread enters ptracestop(), for example because it had received
SIGSTOP from ptrace(PT_ATTACH), it attempts to suspend other threads in
the same process. In the case of a thread sleeping interruptibly in an
SBDRY section, sig_suspend_threads() must wake the thread and allow it to
reach the user-mode boundary. However, sig_suspend_threads() would
erroneously avoid waking up such threads, resulting in an apparent hang.
