Note that r271282 contains only the src change from Clang rev 200797.
This patch file includes two follow-on changes to the test case, which
do not apply to the copy in the FreeBSD tree.
Upstream Clang revisions:
200797:
Debug info: fix a crasher when when emitting debug info for
not-yet-completed templated types. getTypeSize() needs a complete type.
Make it possible to use empty user name ("-U ''") for mount_smbfs(8).
It's just like "-U guest", except that it actually works, at least
with Samba 4, which seems to return authentication failure for "-U guest".

the function calls.

in soalloc().
vt(4): Change the terminal and buffer sizes, even without a font
This fixes a bug where scroll lock would not work for tty #0 when using
vt_vga's textmode. The reason was that this window is created with a
static 256x100 buffer, larger than the real size of 80x25.
Now, in vt_change_font() and vt_compute_drawable_area(), we still
perform operations even of the window has no font loaded (this is the
case in textmode here vw->vw_font == NULL). One of these operation
resizes the buffer accordingly.
In vt_compute_drawable_area(), we take the terminal size as is (ie.
80x25) for the drawable area.
The font argument to vt_set_border() is removed (it was never used) and
the code now uses the computed drawable area instead of re-doing its own
calculation.

Temporarily remove the warning added r270781 - it prints the warning
regardless of whether the usage is correct or not and this generates a
LOT of noise, even when you have specified a mask.

(more) correctly account TX completion status for A-MPDU session frames.
The rules turn out to be:
* for non-aggregation session TX queues - it's either sent or not sent.
* for aggregation session TX queues - if nframes=1, then the status reflects
the completed transmission.
* however, for nframes > 1, then this is just a status reflecting what
the initial transmission did. The compressed BA (immediate or delayed)
may not have yet been received, so the actual frame status is in the
compressed BA updates.
Whilst here, I fiddled with debugging and formatting a bit.
There's also RTS attempts (what the atheros chips call "short retries")
which weren't being logged and they aren't yet being used in the rate
control statistics updates. For now, at least log them.
TODO:
* This still isn't 100% correct! So I have to tinker with this some more.
(The failures aren't always failures..)
* Extend the rate control API in net80211 so it can take both short and
long retry counts.

When entering the kernel with the MMU off assume we are running from a
va == pa map.
I'm not sure the code would work if we are not running from the identity
map as the ARM core may attempt to read the next instruction from an
invalid memory location.
Iterate through all the children instead of returning error when we hit
the first error. This makes the error message give more information
rather than just the first device that causes problem.

Use union sctp_sockstore instead of struct sockaddr_storage. This

There should be no functional change.

SDM rev. 50 defines the use of the next 8 bytes in the xstate header.
It is the compaction bitmask, with the highest bit defining if compact

When registering an association between a device and an xref phandle, create
an entry in the xref list if one doesn't already exist for the given handle.
On a system that uses phandle properties, the init-time scan of the tree
which builds the xref list will pre-create entries for every xref handle
that exists in the data. On systems where the xref and node handles are
synonymous there is no phandle property in referenced nodes, and the xref
list will initialize to an empty state. In the latter case, we still need
to be able to associate a device_t with an xref handle, so we create list
entries on the fly as needed. Since the node and xref handles are
synonymous, we have all the info needed to create a list entry at device
registration time.
The downside to this change is that it basically allows on the fly creation
of xref handles as synonyms of node handles, and the association of a
device_t with them. Whether this is a bug or a feature is in the eye of
the beholder, I guess.

Revert rr271190, it was based on a misunderstanding. The problem of
non-existant device<->xref info needs to be handled by creating the info,
which will come in a subsequent commit.
Add more bits for the XSAVE features from CPUID 0xd, sub-function 1
%eax report.
Print the XSAVE features 0xd/1 in the boot banner. The printcpuinfo()
is executed late enough so that XSAVE is already enabled.
There is no known to me off the shelf hardware that implements any
feature bits except XSAVEOPT, the list is taken from SDM rev. 50. The
banner printing will allow us to note the hardware arrival.

Create a separate structure for per-CPU state saved across suspend and
resume that is a superset of a pcb. Move the FPU state out of the pcb and
into this new structure. As part of this, move the FPU resume code on
amd64 into a C function. This allows resumectx() to still operate only on
a pcb and more closely mirrors the i386 code.

Add OF_xref_from_node_strict() which returns -1 if there is no xref handle
for the node. The default routine returns the untranslated handle, which
is sometimes useful, but sometimes you really need to know there's no
entry in the xref<->node<->device translation table.

Add the fp{get,set}{mask,round} functions to the public symbols in the map.
These are only exported for armv6hf as the soft-float ABIs have these in

Garbage collect NFSMINOFF() from the NFS stack; this unused macro replicates
mbuf-initialisation logic that is best left to centralised mbuf utility
code rather than scattered around the kernel.
Clarify a diagnostic printf() in the mbuf code: M_EXT doesn't necessarily
imply a cluster is attached; it could also refer to some other sort of

Invert AHCI_Q_NOBSYRES quirk meaning, waiting for readiness by default.
I gave up to update list of Marvell chips that require this quirk.
The final nail was growing number of PCIe/M.2 SSDs where Marvell chips

I've looked at the GCC sources and I now understand what's going wrong.
THe C11 keywords are simply nonexistent when using C++ mode. They are
marked as C-only in the parser. This is absolutely impractical for
multiple reasons:
- The C11 keywords do not conflict with C++ naming rules. They all start
with _[A-Z]. There is no reason to make them C-only.
- It makes it practically impossible for people to use these keywords in
C header files and expect them to work from within C++ sources.
As I said in my previous commit message: GCC is by far the weirdest
compiler that I've ever used.
Incredibly weird: GCC 4.7/4.9 do support the _Noreturn and _Thread_local
keywords, but not during bootstrapping. GCC is by far the weirdest
compiler that I've ever used.
The legacy USB circuit tends to give trouble on MacBook.

use a straight buffer instead of an iov w/ 1 segment... The aesni
driver when it hits a mbuf/iov buffer, it mallocs and copies the data
for processing.. This improves perf by ~8-10% on my machine...
I have thoughts of fixing AES-NI so that it can better handle segmented
buffers, which should help improve IPSEC performance, but that is for
the future...
Separate out PCI attachment from the main AHCI driver. Move checks of
PCI IDs into quirks, which mostly fit (though you'd get no argument
from me that AHCI_Q_SATA1_UNIT0 is oddly specific). Set these quirks
in the PCI attachment. Make some shared functions public so that PCI
and possibly other bus attachments can use them.
The split isn't perfect yet, but it is functional. The split will be
perfected as other bus attachments for AHCI are written.
Allow multiple image activators to run on the same execution by changing
imgp->interpreted to a bitmask instead of, functionally, a bool. Each
imgactivator now requires its own flag in interpreted to indicate whether
or not it has already examined argv[0].
Change imgp->interpreted to an unsigned char to add one extra bit for
future use.
With this change, one can execute a shell script from a 64bit host native
make and still get the binmisc image activator to fire for the script
interpreter. Prior to this, execution would fail.
Delete old arm dts tree. This was created by cherry picking from a
full vendor tree. This worked great until it was time to update, but
now it is time to update. Hit the rest button by removing this branch
and re-adding it by a full copy of whatever is in the vendor tree.
Properly trim the vendor tree to include only those files that we want
merged into FreeBSD. Cherry picking from a full vendor tree was too
hard and lead to undestirable svn results.
Note: We only tim the dts* files, we don't trim the dt-bindings tree,
since having all of them causes no problems and the benefit to
trimming there is far out weighed by the cost of doing the trim each
time.
