817045ffb8 Don't need to include assym.h 
Add a missing comma.

e0306b2b8a Add a routine to create an up to an 128 bitmask returned 
in VFP/NEON q0 starting at the rightmost bit (bit 0).

4118c7d32d Slighly improved (can deal with all 16 bytes being non-NUL and quickly 
proceed to next qword).

b54764018c Add a NEON(only) implementation of memset. 
This is a work in progress.

be5ab324d6 Change __XSCALE__ to _ARM_ARCH_DWORD_OK so that any cpu with dword load/store

3e441138b1 Provide an assembler version of _atomic_cas_up for sparc - the C code 
does not compile to something usable in a RAS. See PR 38482.

91f0e20769 Split out modsi3 and umodsi3 from the divsi3 file. This is so that 
we don't get re-defined symbols in libc from libgcc in static linking.
Example: cc -pthread -static main-calls-pthread-create.c

b40d79bcfb Add a ptree_mask_node_p to determine if an item is a mask node, and what 
its non-mask length is.

8588929dc5 Add "consttime_bcmp" and "explicit_bzero" functions for both kernel 
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.
Change some memset/memcmp uses to the new functions where it makes
sense -- these are just some examples, more to come.

85e052c5bf Actually use the assembly version of the atomic function if compiling 
for armv6 or armv7 cpus.  Use atomic_cas_ptr instead of _lock_cas so
we pick up the assembly version when it's used.

2fa47ecfcb Lint seems to prefer that we cast via (void*) and not directly to 
(u_char*), so follow suit.

2953114330 Change CTASSERT to __CTASSERT (the spelling used in <sys/cdefs.h>), 
include <sys/cdefs.h> so that it will be defined,
and move it to a better place.

The previous CTASSERT would never have been used because
of the ifdef.  If it had been used, it would have had
unwanted effects from being just after the "static inline"
that appears when BZERO is defined.

Also move the __RCSID to a more conventional location.
