kernel/oce: Fix sysctl names and firmware updating instructions.
kernel/platform: Remove some #include duplicates.
kernel - Remove Warning: busy page %p found in cache

* Remove the "Warning: busy page %p found in cache" kprintf.  DragonFly
  now allows VM pages to be busied regardless of what queue they are or
  are not on.
kernel: Remove unused invlpg() function
sys/conf/files: Adjust some excessive tabs.
firmware.9: Adjust ARM specific example to one from our tree.
kernel - Flesh out AHCI 1.3 regs / detection (FBSS not yet supported)

* Detect the CAP2 register.  Add definitions for new CAP and CAP2 bits.

* Detect and report FBSS support when a PM is attached.  Note that
  the driver does not yet support FBSS (I'm still tring to find a
  mobo whos AHCI has it).
kernel/aic: Remove redundant #ifdefs.
kernel/asr: Clean up the include jungle a bit.
kernel/dev: Remove some #include duplicates.
kernel: Remove some #include duplicates in vfs/ and vm/
kernel: Remove two unused header files (we use dev/netif/ic_layer's copy).
kernel: Stop building 3 i386 specific modules (ar, glxsb, sbni) on x86_64.
iicbus/iic.h: Sync with FreeBSD
kernel/usb4bsd: Fix ukbd's polled mode (for ddb etc.).
kernel/sppp: Clean up #ifdef jungle a bit.
kernel/net*: Remove some #include duplicates.
kernel/mps: Fix a panic after the recent upgrade.

It was crashing in xpt_done() with a NULL ccb. Reverting FreeBSD's
r249468 fixes that.

Something seems to be missing or different in our CAM here.
Sync zoneinfo database with tzdata2013d from ftp://ftp.iana.org/tz/releases

* africa: Morocco's midsummer transitions this year are July 7 and
    August 10, not July 9 and August 8. (Thanks to Andrew Paprocki.)

* asia: Israel now falls back on the last Sunday of October. (Thanks
    to Ephraim Silverberg.)

* iso3166.tab: Fix typos in the entries for country codes BQ and SX.

    the pre-1880 times by 2 s.

* miscellaneous files: Deemphasize the significance of national borders.
    Update several URLs. Spelling fixes (thanks to Kevin Lyda and
    Jonathan Leffler).
