* combine.c (try_combine): Stop and undo after the first combination
if an autoincrement side-effect on the first insn has effectively
been lost.
The issue was detected in OpenBSD but their fix was not very good. Huge
thanks to the upstream author, Eric Botcazou, for permitting the use of
this patch under GPLv2.

* Do not match symlinks that are followed because of -H or -L. This is
explicitly documented in GNU find's info file and is like -type l.
* Fix matching symlinks in subdirectories when fts changes directories.
Also, avoid some readlink() calls on files that are obviously not symlinks
(because of fts(3) restrictions, not all of them).

related to setting up static device mappings. Since it was only used by
arm/mv/mv_pci.c, it's now just static functions within that file, plus
one public function that gets called only from arm/mv/mv_machdep.c.
The code did not take into account that readlink() does not add a
terminating '\0', and therefore did not work reliably.
As before, symlinks of length PATH_MAX or more are not handled correctly.
(These can only be created on other operating systems.)

One particularly notable addition amongst the kernel config changes is
USB_HOST_ALIGN=32, which may help eliminate data corruption on USB drives.

obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
(aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
requests to its parent (nexus). This allows x86 FDT devices to allocate
both memory and IO requests and removes the last notionally MI use of
fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
FDT_MAP_IRQ and FDT_INTR_MAX have been removed.
static device mappings.
This SoC relied heavily on the fact that all devices were static-mapped
at a fixed address, and it (rather bogusly) used bus_space read and write
calls passing hard-coded virtual addresses instead of proper bus handles,
relying on the fact that the virtual addresses of the mappings were known
at compile time, and relying on the implementation details of arm
bus_space never changing. All such usage was replaced with calls to
bus_space_map() to obtain a proper bus handle for the read/write calls.
This required adjusting some of the #define values that map out hardware
registers, and some of them were renamed in the process to make it clear
which were defining absolute physical addresses and which were defining
offsets. (The ones that just define offsets don't appear to be referenced
and probably serve no value other than perhaps documentation.)
Block objects [1] are a C-level syntactic and runtime feature. They
are similar to standard C functions, but in addition to executable
code they may also contain variable bindings to automatic (stack)
or managed (heap) memory. A block can therefore maintain a set of
state (data) that it can use to impact behavior when executed.
This port is based on Apple's GCC 5646 with some bugfixes from
Apple GCC 5666.3. It has some small differences with the support
in clang, which remains the recommended compiler.
Perhaps the most notable difference is that in GCC that __block
is not actually a keyword, but a macro. There will be workaround
for this issue in a near future. Other issues can be consulted in
the clang documentation [2]
For better compatiblity with Apple's GCC and llvm-gcc some related
fixes and features from Apple have been included. Support for the
non-standard nested functions in GCC is now off by default.
No effort was made to update the ObjC support since FreeBSD doesn't
carry ObjC in the base system, but some of the code crept in and
was more difficult to remove than to adjust.

ability to set any of the other WPA options. Regardless, this is
generally sufficient to associate.
Perhaps in the future this could allow full configuring (e.g. being able
to set "anonymous identity", and perhaps some of the more obscure WPA
options), though perhaps that will better belong in bsdconfig when that
grows wlan config ability.

New algorithm does not create additional lock congestion, while some races
it includes should not be a problem. Those races may keep requests in DRC
cache for some more time by returning ACK position smaller then actual,
but it still should be able to drop thems when proper ACK finally read.
Races of the original algorithm based on TCP seq number were worse because
they happened when reply sequence number were recorded. After that even
correctly read ACKs could not clean DRC sometimes.
