0dbf17e6eb Make kern_nanosleep() and pause_sbt() to use per-CPU sleep queues.
This removes significant sleep queue lock congestion on multithreaded
microbenchmarks, making them scale to multiple CPUs almost linearly.

4b5e84f615 Convert the offset into the bar that contains the MSI-X table to an offset
into the MSI-X table before using it to calculate the table index.

In the common case where the MSI-X table is located at the begining of the
BAR these two offsets are identical and thus the code was working by accident.

This change will fix the case where the MSI-X table is located in the middle
or at the end of the BAR that contains it.

0e168bb8e3 Add a few new fields to the RX vendor radiotap header:
* a flags field that lets me know what's going on;
* the hardware ratecode, unmolested by conversion to a bitrate;
* the HAL rs_flags field, useful for debugging;
* specifically mark aggregate sub-frames.

This stuff sorely needs tidying up - it's missing some important
stuff (eg numdelims) and it would be nice to put the flags at the
beginning rather than at the end.

Tested:

* AR9380, STA mode, 2x2 HT40, monitoring RSSI and EVM values

b9372765c6 - Clang doesn't understand the -mno-thumb-interwork. Only use it with gcc.
- We need to add "-mllvm -arm-enable-ehabi" to clangs CFLAGS when
  generating the unwind tables to tell it to add the required directives to
  the assembly it generates.

536daf817a Tell the unwinder we can't unwind swi_entry. This fixes an infinite loop
when the kernel attempts to unwind through this function.

are currently missing an END macro on ARM.

7554e820bb Attach the elf section headers to the loaded kernel as metadata, so
they can easily be used by later post-processing.  When searching for
a compiled-in fdt blob, use the section headers to get the size and
location of the .dynsym section to do a symbol search.

This fixes a problem where the search could overshoot the symbol
table and wander into the string table.  Sometimes that was harmless
and sometimes it lead to spurious panic messages about an offset
bigger than the module size.

fb769e0f72 __FreeBSD_ARCH_armv6__ is undefined on clang. We can use __ARM_ARCH in
it's place. This makes 'uname -p' correctly output 'armv6' on a kernel
built with clang.

dd9b8b36dd Since ubldr doesn't necessarily load a kernel at the physical address in the
elf headers, mask out the high nibble of that address.  This effectly makes
the entry point the offset from the load address, and it gets adjusted for
the actual load address before jumping to it.

Masking the high nibble makes assumptions about memory layout that are true
for all the arm platforms we support right now, but it makes me uneasy.
This needs to be revisited.

1fc8c346d5 Improve UMTX_PROFILING:
- Use u_int values for length and max_length values
- Add a way to reset the max_length heuristic in order to have the
  possibility to reuse the mechanism consecutively without rebooting
  the machine
- Add a way to quick display top5 contented buckets in the system for
  the max_length value.
  This should give a quick overview on the quality of the hash table
  distribution.
