7d3af7ae88 autofs: Fix a comment on autofs_args 
mount_autofs(8) also uses this.
mount_autofs(8) was added by NetBSD as an optional command (not needed to use autofs).

b770b2aad5 Store the flags passed to SUNXI_CCU_FRACTIONAL macro. 
Previously the macro dropped the flags argument entirely, and did not
initialize the structure with it.

6e1e41dfe9 - On-demand zeroing pages with MOVNTI is crazy. It empties L1/L2/L3. 
- Disable zeroing in the idle loop.  That needs a cache-friendly strategy.

Result: 3 to 4% reduction in kernel build time on my test system.
Inspired by a discussion with Mateusz Guzik and David Maxwell.

6f40daa312 Several improvements. In particular, reduce CS.limit, because Intel CPUs 
perform strict sanity checks, and the previous (too high) limit caused the
VM entry to fail.

6df93363ad Fix regression introduced to ptrace_regs() in rev 1.27: 
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/sys_ptrace_common.c#rev1.27

Size of registers should be determined from tracer, NOT tracee.

Now, 64-bit tracer can manipulate registers of 32-bit tracee again.
gdb for amd64 works for i386 binaries to some extent.

XXX
pullup to netbsd-9 and -8.

try mounting gpt label "cgdroot" as a root filesystem first and
only mount /dev/cgd0a if that gpt label doesn't exist or fails
to mount.

b7b6f4ad9a Fix PR/54074 and PR/54093 completely. 
More similar to the ld.elf_so logic, it is necessary to align with
p_align first.  Also, invert the #ifdef condition for consistency.

Should fix regression for static linking binaries:

b5034f0391 Minor improvements to select/poll: 
- Increase the maximum number of clusters from 32 to 64 for large systems.
  kcpuset_t could potentially be used here but that's an excursion I don't
  want to go on right now.  uint32_t -> uint64_t is very simple.

- In the case of a non-blocking select/poll, or where we won't block
  because there are events ready to report, stop registering interest in
  the back-end objects early.

- Change the wmesg for poll back to "poll".

c825105bdc - Don't give up kpriority boost in preempt(). That's unfair and bad for 
interactive response.  It should only be dropped on final return to user.
- Clear l_dopreempt with atomics and add some comments around concurrency.
- Hold proc_lock over the lightning bolt and loadavg calc, no reason not to.
- cpu_did_preempt() is useless - don't call it.  Will remove soon.
