The older AIO code awakened all pending AIO requests on a socket
when any data arrived. This could result in AIO daemons blocking on
an empty socket buffer. These requests could not be cancelled
which led to a deadlock during process exit. This test reproduces
this case. The newer AIO code is able to cancel the pending AIO
request correctly.

Fix a symbol table handling bug in elfcopy: elfcopy puts .symtab,
.strtab and .shstrtab sections in the end of the output object. If
the input objects have more sections after any of these 3 sections,
the section table will be reordered, and in that case the section
symbols should be regenerated for relocations.
The bug is triggered since newer clang puts .strtab section in the
beginning of the object produced.

(And 4Kn minidump support, but only for amd64.)
Make sure all I/O to the dump device is of the native sector size. To
that end, we keep a native sector sized buffer associated with dump
devices (di->blockbuf) and use it to pad smaller objects as needed (e.g.
kerneldumpheader).
Add dump_write_pad() as a convenience API to dump smaller objects with
zero padding. (Rather than pull in NPM leftpad, we wrote our own.)
Savecore(1) has been updated to deal with these dumps. The format for
512-byte sector dumps should remain backwards compatible.
Minidumps for other architectures are left as an exercise for the
reader.

Prior to this change, vdev_geom_open_by_path would call vdev_geom_attach
prior to verifying the device's GUIDs. vdev_geom_attach calls
vdev_geom_attrchange to set the physpath in the vdev object. The result is
that if the disk could not be found, then the labels for other disks in the
same TLD would overwrite the missing disk's physpath with the physpath of
whichever disk currently has the same devname as the missing one used to
have.

This revision suggests dtsi patches to be used with the original OpenWRT
dtsi files so we can re-use what has already been done in OpenWRT for the
Mediatek/Ralink SoCs.
The only thing that is required after importing this revision should be
the following:
1. Import OpenWRT dts/dtsi files into sys/gnu/dts/mips
2. Run the following script in sys/gnu/dts/mips:
for f in `ls [mr]t*.dtsi`; do
printf "\n#include <fbsd-$f>\n" > $f
done
This will apply our dtsi patches to OpenWRT's dtsi files and will allow us
to re-use dts/dtsi files for ~170 Mediatek/Ralink boards.
Currently our drivers are not 100% compatible with OpenWRT's dts files, but
they're compatible enough.
We can add more functionality in the future that would better leverage the
OpenWRT work as well.

fdt_static_dtb.S dependency in sys/conf/files is currently set as:
$S/boot/fdt/dts/${MACHINE}/${FDT_DTS_FILE}
This is wrong, as what fdt_static_dtb.S actually uses is the DTB file
produced from the FDT_DTS_FILE.
In addition it also makes using DTS files stored in $S/gnu/dts/${MACHINE}/
impossible.
So, change the dependency to "fdt_dtb_file", which seems to be the right
option here anyway.

the following:
1. Give the appropriate board dts file to be used by either:
1.1. edit the SoC kernel config required (e.g., MT7620A_FDT) and include
the required FDT_DTS_FILE makeoption; or
1.2. simply supply FDT_DTS_FILE="xx.dts" on the command line when building
the kernel
Of course, the user can also create a completely new kernel config to
match the desired board and include the SoC kernel config from within
it.
If required, edit the MEDIATEK config file, which includes optional
drivers and comment out the unneeded ones.
2.1. this would only make sense if kernel size is a concern. Even if we
build the kernel with all drivers, if we lzma it and package it as a uImage,
its size is still around 1.1MiB.
The user will have to choose a dts file (or create a new one) from
sys/gnu/dts/mips , where all Mediatek/Ralink dts files will be imported via
a later revision.

write to the End of Interrupt (EOI) register before handling the interrupt.
This should be a noop as it will be set for all edge triggered interrupts,
however this will not be the case for MSI interrupts. These are also edge
triggered, however we should not write to the EOI register until later in
arm_gic_pre_ithread.

Revert r292255 because it can create bounced regions without contiguous
page offsets, which is needed for USB devices.
Another solution would be to force bouncing the full buffer always (even
when only one page requires bouncing), but this seems overly complicated and
unnecessary, and it will probably involve using more bounce pages than the
current code.
