Add support for accelerated AES_CBC in ubsec(4) for BCM5823 and newer.
Update man-page and bump date.
Adjust OpenBSD RCS IDs to reflect roughly the version we are in sync with.
Use $(SHELL) to run move-if-change.
ldscript for ppc64 kernels
Add PCI register definitions
Normal memory is not poolpage memory unless poolpage memory is default memory.
Set ac_install_sh="$SHELL $ac_aux_dir/$ac_t -c"
instead of ac_install_sh="$ac_aux_dir/$ac_t -c"
in all configure scripts in the gcc/dist tree.
This ensures that the install-sh script is always run
under the correct shell.
Move the WDT register definitions to the C source to unclutter the directory
Enable the exywdt watchdog since its now implemented and remove the
VERBOSE_INIT_ARM; its debugging is not needed normally.
Add 6.0.5 and 6.1.4.
Set ac_install_sh="$SHELL $ac_aux_dir/$ac_t -c"
instead of ac_install_sh="$ac_aux_dir/$ac_t -c"
in all configure scripts in the gcc.old/dist tree.
This ensures that the install-sh script is always run
under the correct shell.
Add note about sending bsd-family-tree changes upstream to FreeBSD.
Move the watchdog registers back to the exynos_reg.h
Clarify the NetBSD-specific and Linux-specific code at the top of
compat_defs.h:

* Explain why _NETBSD_SOURCE should not be defined on NetBSD.
* Move NetBSD-specific block to the top of the file.
* Improve comment about Linux <feature.h>.
* Move #undef _POSIX_SOURCE and #undef _POSIX_C_SOURCE to the
  Linux-specific block instead of a place that would affect all
  non-NetBSD platforms.  This makes the code match the comment.

This will need to be re-visited if other platforms also need
#undef _POSIX_SOURCE or #undef _POSIX_C_SOURCE.  At present, I suspect
that they are needed only for Linux.
Use the conspeed and div/frac from the uart to figure out the frequency
for the console.   XXX until we actually compute from the chip clocks.
Basic unwind support for HPPA.
copyinargs: Plug theoretical memory leak when fakearg is too long.

Pointed out & reviewed by Maxime Villard.
copyinargs: Shorten a local var name.
execve_runproc: Isolate emul specific code into a function.
