Make is possible to de-select depended options (which are processed in
a separate pass). Example:
<files.foo>
defflag SOME_OPTION: SOME_OTHER_OPTION
<MYFOO>
options SOME_OPTION
no options SOME_OTHER_OPTION
Prior to this change, a warning that SOME_OTHER_OPTION was not selected
would be issued and SOME_OTHER_OPTION would remain selected in the output.
After this change, no warning is issued and SOME_OTHER_OPTION is not
selected in the output as expected.
This does not have broad utility, but can quite useful in certain situations.
s/mipsNN_cp0_cause_read/mips_cp0_cause_read/ in INGENIC_INTR_DEBUG guarded code.
It is disabled though, thus moving #ifdef 0 higher to make option build.
(otherwise buffer is unused and compiler complains)
Not sure why the code was disabled, potentially it was too verbose.
Replace MFC0 macro with CP0 accessor functions in debug code.
Include ingenic_var.h in ingenic/mainbus.c when INGENIC_DEBUG is enabled and
move "opt_ingenic.h" higher so this option is visible for the include.
MFC0 macro was removed in ingenic_regs.h v1.25, but debug code was not adopted.
Fixes INGENIC_DEBUG enabled build for the evbmips CI20 kernel config.
Rename the "basic 4BSD" disklabel routines readdisklabel_4bsd()
and writedisklabel_4bsd(), but add weak aliases to the standard
names. This easily allows machine-specific code to look for an
odd-ball machine-firmware-specific format that might be required
only for booting but otherwise use garden-variety BSD disklabels.
nvmm(4): Fix race in clearing vcpu->comm->stop bit.
Don't touch vcpu after nvmm_vcpu_put when we no longer hold the lock,
and certainly not after nvmm_machine_put when the vcpu could even be
freed.

nvmm(4) vmx: Don't read VMCS_EXIT_REASON if vmlaunch/vmresume failed.
It is not valid in that case; we might end up operating on the
_previous_ successful vmlaunch/vmresume's now-stale exit reason.

proc_regio: Clarify control flow and sprinkle comments.
Use `if (error) goto out' instead of `if (error == 0) error = ...' to
make the error case non-linear and indented, and the success case a
straight line of logic.
No functional change intended.

ptrace/procfs: Take lwp lock around process_read/write_(fp)regs(32).
And verify that the lwp is in LSSTOP state before trying to read.
Otherwise, we might catch an lwp while it's still running on the CPU,
with all FPU state active, making the result unstable and tripping
assertions on some architectures.

I was planning to do this in the same commit that fixes it, to keep

nfs: Avoid UB in integer shift amounts.
Just use ilog2 explicitly here, instead of writing out a loop with
shifts and increments to compute it more slowly and buggily. Note
the confusing fencepost adjustment. Clamp _PC_FILESIZEBITS at the
actual size of off_t since we can't go beyond that.

Make console input on virt68k 8-bit clean.
On signed-char ports you can't feed a "char *" to the tty layer. A cursory
glance for more instances of this didn't find any but it's possible.
Simplify the interface between the timers and the clock infrastructure,
and allow the clock infrastructure to select clock roles without having
netbsd,hardclock or netbsd,statclock properties in /chosen (they're now
optional).
Add fdtbus_get_reg_shift() to get the "reg-shift" property and provide
a default value, rather than open-coding it everywhere it's used. It's
common enough in various device bindings, and ePAPR describes it as a
generic device property.
