like the args to the config space accessors these functions replaced.
This reduces the likelyhood of overflow when the args are used in
macros on the alpha. This prevents memory management faults when
probing the pci bus on sables, multias and nonames.

- Use ACPI_PHYSICAL_ADDRESS
- RSDT -> XSDT
- FACP -> FADT
- No APIC table support
- Don't install a global EC handler; this has bad side-effects
(it invokes _REG in *all* EC spaces in the namespace!)
- Check for PCI bus instances already existing before adding them
files. Mostly -I${.CURDIR} was needed -- especially for YACC generated
files as the new cpp does not look in the ultimate source file
(ie, the .y file)'s directory as told by the "#line" directive. Some were
misspellings of "-I${.CURDIR}" as "-I.".
but a hack! Add `flags 0x8000' to the psm driver to enable it.
The psm driver will try to get out of out-of-sync situation
by disabling the mouse and immediately enable it again.
If you are seeing this out-of-sync problem because of an
incompetent(?!) KVM switch, this hack will NOT be good
for you. However, if you are occasionally seeing the
problem because of lost mouse interrupt, this might help.
lock. Otherwise, if we block on the backing mutex while releasing the
allproc lock, then when we resume, we will be at SRUN, and we will stay
that way all the way through cpu_exit. As a result, our parent will never
harvest us.
depend on MUTEX_DEBUG. The MUTEX_DEBUG option turns on extra assertions
and checks to verify that mutexes themselves are implemented properly.
The WITNESS option uses extra checks and diagnostics to verify that other
code is using mutexes properly.
o In practice: the comment indicates that all but umask and
environmental variables of the users login class are applied when su
occurs, unless -m is used to specify a class. This was incorrect;
in practice, the uid, gids, resources, and priority were set, and
then resources and priority were selectively removed. This meant
that some aspects of the user context were not set, including handling
of login events (wtmp, utmp), as well as the path specified in
login.conf.
o I changed it so that the behavior is the same, but instead,
LOGIN_SETALL is used, and appropriate flags are removed, including
the LOGIN_SETLOGIN and LOGIN_SETPATH entries that were implicitly
not present before. I also updated the comment to reflect
reality, selecting reality as the "correct" behavior.
o This has the practical benefit that as new LOGIN_SET* flags are
introduced, they are supported by su unless specifically disabled.
For example, of a LOGIN_SETLABEL flag is introduced to support
MAC labels determined by the user's login class, then su no longer
has to be modified.
o It might be desirable to have su use LOGIN_SETPATH depending on
its command line parameters, as it might or might not be
considered part of the "environment".
