72e80cddc0 Unbreak ARMv6 world.
The new compiler_rt library imported with clang 4.0.0 have several fatal
issues (non-functional __udivsi3 for example) with ARM specific instrict
functions. As temporary workaround, until upstream solve these problems,
disable all thumb[1][2] related feature.

6fffdbbd67 Add initial support for UNMAP granularity.
Report UNMAP granularity as stripesize/-offset if we have no other values
to report there.

Add new quirk DA_Q_STRICT_UNMAP for cases when target is too critical to
misaligned UNMAP request, reporting errors instead of being suboptimal.
Setting this quirk makes da periph to forcefully align all UNMAP requests
to avoid those errors by the cost of some odd ranges not being UNMAP'ed.
This makes UNMAP usable within VMware 6.x VMs, just now 100% efficient.

14c5024db8 Cleanup the LinuxKPI slab implementation.
Put large functions into linux_slab.c instead of declaring them static
inline.

Add support for more memory allocation wrappers like kmalloc_array()
and __vmalloc().

Make sure either the M_WAITOK or the M_NOWAIT flag is set and mask
away unused memory allocation flags before calling FreeBSD's malloc()
routine.

Move kmalloc_node() definition to slab.h where it belongs.

Implement support for the SLAB_DESTROY_BY_RCU feature when creating a
kmem_cache which basically means kmem_cache memory is freed using
call_rcu().

62c6b30e5c Fix booting with >4GB RAM on PowerMac G5 hardware
===
From Nathan Whitehorn:

Open Firmware runs in virtual mode on the Powermac G5. This runs inside the
kernel page table, which preserves all address translations made by OF before
the kernel starts; as a result, the kernel address space is a strict superset of
OF's.

Where this explodes is if OF uses an unmapped SLB entry. The SLB fault handler
runs in real mode and refers to the PCPU pointer in SPRG0, which blows up the
kernel. Having a value of SPRG0 that works for the kernel is less fatal than
preserving OF's value in this case.

===

The result of this is seemingly random panics from NULL dereferences, or hangs
immediately upon boot.  By not restoring SPRG0 for Open Firmware entry the
kernel PCPU pointer is preserved and SLB faults are successful, resulting in a
stable kernel.

a8a18dd590 Make multi-namespace nvme drives more robust.
Fix assumptions about name spaces in NVME driver. First, it assumes
cdata.nn is the number of configured devices. However, it is the
number of supported name spaces. Second, it assumes that there will
never be more than 16 name spaces supported, but a certain drive I'm
testing reports 1024. It assumes that name spaces are a tightly packed
namespace, but the standard seems to indicate otherwise. Finally, it
assumes that an error would be generated when quearying an
unconfigured namespace. Instead, it succeeds but the identify data is
all zeros.

Fix these by limiting the number of name spaces we probe to 16. Remove
aborting when we find one in error. When the size of the name space is
zero, ignore it.

This is admittedly a bandaide. The long term fix will be to
participate in the enumeration and name space change protocols
definfed in the NVNe standard.

0499b37cea Bring in snapshot of the MdePkg from Tianocore's EDK2 project at git
hash 7babb4372e6a34cbbc54249b25056272a5a9924c From 2017-Mar-03.

EDK2 is Intel's BSD Licensed UEFI implementation. We'll be bringing in
various routines from there rather than reimplementing them from
scratch for libefivar and the EFI boot loader.

The upstream repo has ^M ending on everything (sometimes multiple
times!), so the following script was run prior to import so changes we
have to do don't first include changing every line:

% find . -type f | xargs -n 1 sed -I.BAK -e `printf "s/\r//g"`
% find . -name \*.BAK | xargs rm

Also, only the MdePkg was brought in (it's 17MB, while the entire repo
is 250MB). It's almost completely certain nothing else will be used,
but if it is, it can be brough in along side MdePkg in the future.

857bb3d01e firewire/sbp: try to improve locking, plus a few style nits
This change tries to fix the most obvious locking problems.

sbp_cam_scan_lun() is never called with the sbp lock held, so the lock
needs to be acquired internally (if it's needed at all).
Without this change a kernel with INVARIANTS panics when a firewire disk
is connected:
  panic: mutex sbp not owned at /usr/src/sys/dev/firewire/sbp.c:967
  KDB: stack backtrace:
  db_trace_self_wrapper() at 0xffffffff80420bbb = db_trace_self_wrapper+0x2b/frame 0xfffffe0504df0930
  kdb_backtrace() at 0xffffffff80670359 = kdb_backtrace+0x39/frame 0xfffffe0504df09e0
  vpanic() at 0xffffffff8063986c = vpanic+0x14c/frame 0xfffffe0504df0a20
  panic() at 0xffffffff806395b3 = panic+0x43/frame 0xfffffe0504df0a80
  __mtx_assert() at 0xffffffff8061c40d = __mtx_assert+0xed/frame 0xfffffe0504df0ac0
  sbp_cam_scan_lun() at 0xffffffff80474667 = sbp_cam_scan_lun+0x37/frame 0xfffffe0504df0af0
  xpt_done_process() at 0xffffffff802aacfa = xpt_done_process+0x2da/frame 0xfffffe0504df0b30
  xpt_done_td() at 0xffffffff802ac2e5 = xpt_done_td+0xd5/frame 0xfffffe0504df0b80
  fork_exit() at 0xffffffff805ff72f = fork_exit+0xdf/frame 0xfffffe0504df0bf0
  fork_trampoline() at 0xffffffff8082483e = fork_trampoline+0xe/frame
  0xfffffe0504df0bf0
  --- trap 0, rip = 0, rsp = 0, rbp = 0 ---

Also, I tried to reduce the scope of the sbp lock to avoid holding it
while doing bus_dma allocations.

The code badly needs some re-engineering.  SBP really should implement
a CAM transport, so that it avoids control flow inversion when re-scanning
the bus.  Also, the sbp lock seems to be too coarse.

Additionally, the commit includes some changes not related to locking.

- sbp_cam_scan_lun: restore CAM_DEV_QFREEZE before re-queueing the ccb
  because xpt_setup_ccb resets ccb_h.flags
- sbp_post_busreset: call xpt_release_simq only if it's actually frozen
- don't place private SIMQ_FREEZED flag (sic, "freezed") into sim->flags,
  use sbp->flags for that
- some style fixes and control flow enhancements

b38bd91f4f don't stop in issignal() if P_SINGLE_EXIT is set
Suppose a traced process is stopped in ptracestop() due to receipt of a
SIGSTOP signal, and is awaiting orders from the tracing process on how
to handle the signal. Before sending any such orders, the tracing
process exits. This should kill the traced process. But suppose a second
thread handles the SIGKILL and proceeds to exit1(), calling
thread_single(). The first thread will now awaken and will have a chance
to check once more if it should go to sleep due to the SIGSTOP.  It must
not sleep after P_SINGLE_EXIT has been set; this would prevent the
SIGKILL from taking effect, leaving a stopped orphan behind after the
tracing process dies.

Also add new tests for this condition.
