all the debugging code into the function versions of the mutex operations
in kern_mutex.c. This reduced the __mtx_* macros to simply wrappers of
the _{get,rel}_lock_* macros, so the __mtx_* macros were also abolished in
favor of just calling the _{get,rel}_lock_* macros. The tangled hairy mass
of macros calling macros is at least a bit more sane now.
* Don't get confused when memory regions don't lie on page boundaries -
remember our page size is typically larger than the firmware's page size.
* Add a function ia64_running_in_simulator() which is intended to detect
whether the kernel is running in SKI or on real hardware.
environment. This fixes an annoying bug where hitting Ctrl-C and
telling sysinstall to 'restart' will do no such thing since many of
the options are still set and so you won't be prompted for them
again.

variable to check for debug functionality. Previously, you had to set
both 'debug' and 'SYSINSTALL_DEBUG' to get a log of sysinstall's
activities. Now, only 'debug' is necessary.
ppc to go into EPP mode. These 8 inputs are timestamped in polled
loop so their resolution will be nanoseconds but their granularity
will only be 1/hz.
Remove explicit mention of IP stack, since it might not be accurate for all
interfaces.
Change if_enable to if_capenable, as it is spelled.

selrecord() in ptcpoll(). The pre-KSE code used the passed in proc pointer
rather than curproc, and an earlier seltrue() call uses the passed in
thread and not curthread.
was locked by the proc lock and td_flags is locked by the sched_lock.
The places that read, set, and cleared TDF_SELECT weren't updated, so they
read and modified td_flags w/o holding the sched_lock, meaning that they
could corrupt the per-thread flags field. As an immediate band-aid,
grab sched_lock while reading and manipulating td_flags in relation to
TDF_SELECT. This will probably be cleaned up some later on.
credentials rather than the real credentials. This is useful for
implementing GUI's which need to modify icons based on access rights,
but where use of open(2) is too expensive, use of stat(2) doesn't
reflect the file system's real protection model, and use of
access() suffers from real/effective credential confusion. This
implementation provides the same semantics as the call of the same
name on SCO OpenServer. Note: using this call improperly can
leave you subject to some of the same races present in the
access(2) call.
o To implement this, break out the basic logic of access(2) into
vpaccess(), which accepts a passed credential to perform the
invocation of VOP_ACCESS(). Add eaccess(2) to invoke vpaccess(),
and modify access(2) to use vpaccess().
