no one else has stepped forward to claim it. It'll be in the Attic for safe
keeping for now.
Use kern_open() to implement creat() rather than taking the long route
through open(). Mark creat as MPSAFE.
While I'm at it, mark nosys() (syscall 0) as MPSAFE, for all the
difference it will make.
set it to avoid the need for a bunch of code that tests whether or
not the lock member is set to REQ_WIRED in order to determine which
length member should be used.
Fix another bug in the oldlen return value code.
Fix a potential wired memory leak if a sysctl handler uses
sysctl_wire_old_buffer() and returns an EAGAIN error to trigger
a retry.
If vslock() returns ENOMEM, sysctl_wire_old_buffer() should set
wiredlen to zero and return zero (success) so that the handler will
operate according to sysctl(3):
The size of the buffer is given by the location specified by
oldlenp before the call, and that location gives the amount
of data copied after a successful call and after a call that
returns with the error code ENOMEM.
The handler will return an ENOMEM error because the zero length
buffer will overflow.

ptrace_set_pc(), and cpu_ptrace() so that those functions are free to
acquire Giant, sleep, etc. We already do a PHOLD/PRELE around them so
that it is safe to sleep inside of these routines if necessary. This
allows ptrace() to be marked MP safe again as it no longer triggers lock
order reversals on Alpha.

snprintf() and vsnprintf() in FreeBSD kernel land).
This is needed by the Intel Centrino 2200BG driver. Unfortunately, this
driver still doesn't work right with Project Evil even with this tweak,
but I'm unable to diagnose the problem since I don't have access to a
sample card.
- Add <sys/param.h> and <limits.h> where required (do not depend on other
headers pulling it in).
- __dead -> __dead2
- #if defined() -> #ifdef
- Remove ugly PRIu64 macros and use %llu w/ (unsigned long long) cast.
All changes looped back to OpenBSD (where applicable) for easier sync in the
future.

This adds support for cardbus ATA/SATA controllers. I get roughly the
same transfer speeds as on true PCI controllers. Nice to be able to add
a couble of "real" disks to a laptop :)
