- cv_wait and friends: after resuming execution, check to see if we have
been restarted as a result of cv_signal. If we have, but cannot take
the wakeup (because of eg a pending Unix signal or timeout) then try to
ensure that another LWP sees it. This is necessary because there may
be multiple waiters, and at least one should take the wakeup if possible.
Prompted by a discussion with pooka@.
- typedef struct lwp lwp_t;
- int -> bool, struct lwp -> lwp_t in a few places.
counterparts apart from not adding the new type to the link set and
hence not registering automatically at boot time. This can be used
to avoid a separate #ifdef _LKM path in some cases.
bunch of bugs.
* park structures are now always allocated from a pool instead of a
mixed stack/malloc allocation
* get rid of the whole adjbuf concept, always just alloc the maximal
amount of memory to satisfy a request
* little regression: don't allow interrupting wait from file system
to userspace; this had problems already before, but now the problems
really started to shine through. I'll try to make this work again
some day.
* fix bmap to return a sensible value in runp
As a result of this a user could supply a bad 'sockaddr' structure to
clnp_route() via connect(2).

__attribute__((always_inline)) or gcc might decide not to inline them,
resulting in P2->P1 call while we mess with the cache, and kernel
would just hang immediately on boot.
platforms that don't provide these services.
In drm_mmap, don't wrap the return value with atop() if we're on macppc.
While we're here, fix:
pci_intr_establish(&dev->pa.pa_pc, ...);
to:
pci_intr_establish(dev->pa.pa_pc, ...);
The former doesn't even compile on macppc, and I'm amazed that it works at
all anywhere else.
test(1) scans for "operators" linearly in an array using strcmp() to
find a match. Since the list of "operators" is fixed, split them
into one and two character ones, and ones that start with a `-' and
ones they don't. This way we can optimize the compare function to
just check for one or two characters. Sort and use bsearch(3). We
could have used a single sorted array and bsearch(3), to save some
complexity, but I decided to be a bit fancier.
files. (It was already possible to use several -s options.)
* Change man page to refer to "-s tgzdir" instead of "-s tempdir",
to reduce confusion between tempdir and temproot.
* Always use a temproot directory, even if passed "-s tgzdir".
* Always invoke "postinstall check", even when not using a source dir.
* Add a BUGS section saying that using -s srcdir is not recommended.
