Restrict strictly-aligned versions of memcmp(9), memcpy(9), and
memmove(9) to 403, instead of all evbppc machines.

Introduce strict-align LIBKERN_MD_FLAGS for this purpose.

Improve previous:

- Add suffix ``d'' for mkdep(1).
- Improve comment a little...

For evbppc, use C version of memcpy(3), memcmp(3), and memmove(3)
consistently for *.{po,pico,go} (for RUMP), in order to avoid
alignment faults for 403.

Add the _restgpr* and _savegpr* entries that GCC 4.5 wants. This file is
designed to support the other GCC 4.5 variants that may be required.

Kill _NOREGNAMES. Everything should be using %rX now. If it doesn't it
soon will.

branches: 1.29.2;
Add -D_NOREGNAMES

Move that majority of the 'SRCS+= foo.c' into the main Makefile.libkern.
Any .S files added by the arch/*/Makefile.inc cause the .c file to
be excluded.
Specific exclusions added using NO_SRCS to match previous files.
At least sparc, sparc64, i386, amd64 and vax GENERIC still build.
(There is a fubar with the naming of the byte-swap files ...)

Split the lines that add .c to SRCS from those that add .S
No changes (apart from the order) intended.

- remove bcmp(9), bcopy(9), and bzero(9) from libkern since <sys/systm.h> has
macro which replace them with mem*() functions in #ifdef _KERNEL as noted
in man pages
- move declarations of bcopy(3) and bzero(3) into <lib/libsa/stand.h>
since they are still in libsa for some MD standalone sources
(I guess all bcmp(3) in standalone sources have been replaced with memcmp(3)
but they should be replaced with memcmp() anyway)

Back out the ppc assembler changes for memcpy/memmove/memcmp on evbppc.
It breaks the explora because the cpu (403) cannot deal with unaligned
accesses. Reported by Juergen Hannken-Illjes.

branches: 1.24.70;
merge ktrace-lwp.

Add a memset.S (does not use dcbz; to be added later). It does both bzero
and memset.

branches: 1.22.2;
Switch back to generic bzero/memset until new one is shown to work.

Actually use bzero.S. Also fix bzero to use GET_CPUINFO

Don't make memset.c since bzero.o has memset in addition to bzero.

Disable bzero/memset assembler implementation until the dependency
problem on assym.h is sorted out and TRW to get at CACHELINESIZE in
the kernel is determined.

Add assembler version of strlen.

Add assembler versions of ffs, bzero and memset.

remove memcpy.c -- I forgot this gets built anyway

remove memmove.c -- I forgot this gets built anyway

add memcmp.c memcpy.c memmove.c

Fix typo.

Don't list bcopy.c here, since we only want memcpy() and not bcopy().
XXX What a kluge!

We need memcpy().

Add some missing things.

Pull in [hn]to[nh][ls].c.

add rules like those in libc to build strchr() and strrchr() (the latter
is being added to libkern by this commit). remove strchr.c from
archs' Makefile.inc files to go along with this. (If an arch has
a .S version, it should be copied down and added to the apropriate
Makefile.inc.)

add memchr() to libkern

Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

branches: 1.2.8;
add strchr() to libkern. strchr.c copied from libc's "index.c", but with
appropriate definitions so that it'll build strchr(), and so that it builds
correctly in libkern (needed to #define NULL).

PowerPC port

Add a memset.S (does not use dcbz; to be added later). It does both bzero
and memset.

branches: 1.5.2;
Actually use bzero.S. Also fix bzero to use GET_CPUINFO

cpu_info is not in spr0, but spr_g_0.

shouldn't need .size for ppc64.

Fix bug when only restoring r31 (lr was not being restored properly).

fix the names of the _END symbols passed to .size; fixes rump issues,
and kernels still work fine, and ofwboot still links.

Add the _restgpr* and _savegpr* entries that GCC 4.5 wants. This file is
designed to support the other GCC 4.5 variants that may be required.

Don't define _NOREGNAMES since all of libkern is now compiled with it.

Refresh from libc.

Use size_t in prototype (so this will be LP64 clean for PPC64 someday).
Calculate len separately for icache & dcache in case each has different
cacheline widths. Make the code for both loops the same except for the
dcbst/icbi. Deal with sizes >=2GB properly (like that'll happen but ...)
