Fixed macros for temporarily relinquishing and restoring setuid/setgid
privileges so that they never change the real user and group IDs of
the calling process.
The setre[ug]id() calls are still used in the REDUCE_PERM macro (with
the r[ug]id arguments of -1) so that the call changes the saved user
and group IDs of the process to that specified.
Also, the panic() and perr() functions had insufficient privileges to
delete the problematic file under /var/at.
documented behavior. Only a certain set of file flags were recognized,
and "no" flags did not match files that have corresponding flags bits
turned off.
Fix and extend the -flags functionality as follows:
: -flags [-|+]<flags>,<notflags>
: The flags are specified using symbolic names (see chflags(1)).
: Those with the "no" prefix (except "nodump") are said to be
: <notflags>. Flags in <flags> are checked to be set, and flags in
: <notflags> are checked to be not set. Note that this is different
: from -perm, which only allows the user to specify mode bits that
: are set.
:
: If flags are preceded by a dash (``-''), this primary evaluates
: to true if at least all of the bits in <flags> and none of the bits
: in <notflags> are set in the file's flags bits. If flags are pre-
: ceded by a plus (``+''), this primary evaluates to true if any of
: the bits in <flags> is set in the file's flags bits, or any of the
: bits in <notflags> is not set in the file's flags bits. Otherwise,
: this primary evaluates to true if the bits in <flags> exactly match
: the file's flags bits, and none of the <flags> bits match those of
: <notflags>.

Note that -l remains an ugly exception, to which no known rules apply,
since the specification of a single option multiple times isn't normal
standards-compliant CLI behaviour.

function and csc interrupt routing path (eg, ISA or PCI) so that we
can more easily switch between the two.
When we don't have a card ISR, put the function interrupt into ISA
mode. This effectively masks the interrupt since it happens once, and
not again until we have an ISR. This should help hangs, and might
help people that unwisely update the kernel w/o updating pccardd.
This is done at mapirq time.
Force CL-PD6729/30 to use ISA interrupt routing and maybe even detect
the number of pccard slots properly (this is still WIP). We aren't
going to support PCI interrupts for this release. A future release
should support them, however. Shibata-san's 3.3V fixes are not
included.
Add a hack which should, in i386, rewrite IRQ 0 cardbus bridges to be
IRQ 255, which should cause interrupts to be routed. This is mostly
untested since my one tester disappeared after reporting nothing
changed.
Implement, but do not use, a power method called cardbus. It looked
like a great way to get around the 3.3V problem, but it seems that you
can only use it to power cardbus cards (I get no CIS when I enable it,
so maybe we're programming things bogusly).
GC the intr and argp stuff from the slot database.
Improve the ToPIC support with the power hacks that Nakagawa-san
published in FreeBSD Press and that Hiroyuki Aizu-san ported to
-stable. The ToPIC hacks were for 3.3V support in ToPIC 100, but it
looks like the '97 also has identical registers, so use them too.
Add some #defines for the cardbus power stuff.
Finally implement making CSC on the Ricoh chips ISA or PCI. This will
allow polling mode to work on vaios, I think.
Add some minor debugging. This should likely be cleaned up or put
behing a bootverbose.
Some of this work, and earlier work, was influanced by Chiharu
Shibata-san's power handing patches posted to bsd-nomads:15866.

16 bits access is required by nsp driver to work in SMIT mode.
Since previously (1.65 and before in current, and 1.46.28 and before
in stable branch) 16 bits access was default, I hope it will break nothing.

Improve handling of cross-builds (which requires creation of

The "picobsd" script will not probably work on -current because it still
uses 'vn' instead of 'md', but i am commiting it anyways to keep it
in sync with the version in -stable.
