if all registers are 0xff.
This allows me to run with flags 0xc0ff on my IBM-DMCA-21440 disk, which
gives 5MB/sec sequential read :-)
If you have a laptop, try adding flag 0x4000 to your disk, and tell me if
it makes any difference for you.
cache lines. Removed the struct ip proto since only a couple of chars
were actually being used in it. Changed the order of compares in the
PCB hash lookup to take advantage of partial cache line fills (on PPro).

Don't return EPERM in setre[ug]id() just because the caller passes in
the current effective id in the second arg (ie: no change), as suggested
by ache.
uid/gid in question was in the cache, but did not exist
in the password file. This causes the -nouser and -nogroup
options to find(1) to only print the first file owned by
an unknown user/group in some cases.
Use snprintf instead of sprintf to avoid buffer overflows
Use snprintf in uu_lockerr instead of lots of hardcoded constants
and not null-terminated strncpy
Return "" for OK and "device in use" for INUSE, it allows simple
strcpy(buf, uu_lockerr(retcode)) without testing for special OK
case (NULL was there) and obtaining meaningful result for INUSE
("" was there) without special testing for it too.
1) Fix mkdir -p to exit with the proper exit status and issue an error
message if it was unable to create all of the specified directories
and they did not previously exist. POSIX says:
The mkdir utility shall exit with one of the following values:
0 All the specified directories were created successfully or the
-p option was specified and all the specified directories now
exist.
E.g.
% mkdir -p /var/mkdir
mkdir: /var/mkdir: Permission denied
% touch /tmp/file
% mkdir -p /tmp/file/dir
mkdir: /tmp/file: Not a directory
Previously the above examples would exit with a zero exit status
and no error message. Something like the following run as a
normal user will still not produce an error:
% id
uid=629(mpp) gid=629(mpp)....
% mkdir -p /usr/local/etc
% ls -ld /usr/local/etc
drwxr-xr-x 4 bin bin 512 Dec 26 14:55 /usr/local/etc/
2) Cleaned up the mode handling to be more efficient when multiple
directories are being created.
3) Fixed a problem where directories could be created with the wrong mode
if the the -p option was specified and the build() routine returned
and error. It would leave the umask set incorrectly at this point.
4) Removed an unused variable.
Closes PR# 2304.
