b440e965da o Another round fixes for mmc(4), mmcsd(4) and sdhci(4) regarding
comments, marking unused parameters as such, style(9), whitespace,
  etc.
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
  - Remove redundant assignments of the default bus_generic_print_child
    device method (I've whipped these out of the tree as part of r227843
    once, but they keep coming back ...),
  - use DEVMETHOD_END,
  - use NULL instead of 0 for pointers.
o Trim/adjust includes.

e1f21017a3 [mips/onionomega] WiFi & gpio kernel configuration bits
This patch adds missing hints for ath0 (eepromaddr) and GPIO (mask & leds).
ath0 doesn't work without eeprom hints, so this commit should make wifi
works on Onion Omega.

GPIO mask is required if you want to use gpiobus and GPIO pins on your
board. Onion Omega has several leds connected to gpio pins (one on board,
one color on dock).
This commit adds mask for gpiobus and allow you to turn off/on leds via
/dev/leds/{board,blue,green,red} (on by default).

Tested on Onion Omega 1.

58ffa42f64 Use db_printsym() to display function names in stack traces.
Previously, the stack unwinder tried to locate the start of the function
in each frame by walking backwards until it found an instruction that
modified the stack pointer and then assumed that was the first instruction
in a function.  The unwinder would only print a function name if the
starting instruction's address was an exact match for a symbol name.
However, not all functions generated by modern compilers start off functions
with that instruction.  For those functions, the unwinder would fail to
find a matching function name.  As a result, most frames in a stack
trace would be printed as raw hex PC's instead of a function name.

Stop depending on this incorrect assumption and just use db_printsym()
like other platforms to display the function name and offset for each
frame.  This generates a far more useful stack trace.

While here, don't print out curproc's pid at the end of the trace.  The
pid was always from curproc even if tracing some other process.

In addition, remove some rotted comments about hardcoded constants that
are no longer hardcoded.

da53b41194 Only call stacktrace_subr() from DDB.
There was a single call to stacktrace() under an #ifdef DEBUG to obtain
a stack trace during a fault that resulted in a function pointer to a
printf function being passed to stacktrace_subr() in db_trace.c.  The
kernel now has existing interfaces for obtaining a stack trace outside
of DDB (kdb_backtrace(), or the stack_*() API) that should be used instead.
Rather than fix the one call however, remove it since the kernel will
dump a trace anyway once it panics.

Make stacktrace_subr() static, remove the function pointer and change it
to use db_printf() explicitly.

While here, dump the value of the CAUSE and BADVADDR registers when
crossing a trapframe.

8e7c7e4ed7 Use mips_dcache_wbinv_range instead of mips_dcache_wb_range on CPU_XBURST
Ingenic CPUs treat plain cache writeback as local-only operation and do
nothing if that is a remote CPU that holds the dirty cache line. They
do broadcast invalidate and write-and-invalidate to other cores though,
so take advantage of that and use wbinv in place of wb as this still gives
us required busdma semantics. Otherwise we'd have to do IPI to remote CPU
ourselves.
