* drop async transfer requests on the floor (no, this does not make
anything work, but it's the easiest way to prevent a receive pipe
transfer request from hanging everything. one tiny bugstep at a time ...)
since ltsleep abuses "while (!mutex_tryenter()) continue;" for NOT
releasing the kernel biglock before sleeping, we cannot do a normal
mutex_enter() in the wakeup path, or otherwise we might be a
situation where the sleeper holds the kernel lock and wants the
sleepermutex (and will not back down) and the wakeupper holds the
sleepermutex and wants the kernel lock. So introduce kernel lock
backdown to the wakeup path.
queue mutex doesn't work very well. I get various deadlocks and corrupted
queue entries. Change to IPL_SCHED [IPL_CLOCK] to block IPI interrupts
while the cpu is mucking with the shootdown queue.
vfs in nature, and therefore it belongs here (can't load a firmware
from a file system without file system support, right?). Rename
rump_cwdi to cwdi0, since firmload depends on that name (naughty
firmload).
which take softnet_lock and might run before the lock is actually
initialized. Also, soinit() itself already calls soinit2(), so no
need to call it twice.
Don't try to load a driver module if the driver is already exist but just
not attached. [bc]dev_open() could return ENXIO even if the driver exists.

to reuse any elements. Look in the whole list instead.

- Rename sched_init() to synch_init(), and introduce a new sched_init()
in sys_sched.c where we (a) initialize the sysctl node (no more
link-set) and (b) listen on the process scope with sched_listener.

that CERROR returns -1 in %a0 in addition to %d0 and %d1, to make functions
like mmap(2), mremap(2), shmat(2) or sbrk(2) return -1 in case of an error.
A side effect of this bug was a segfault caused by jemalloc, when mmap()
failed.
close to it). Useful for secmodels.
Replace open-coded form with it in secmodel code (securelevel, keylock).
Note: I need to find a way to make secmodel_keylock.c ~<100 lines.
- Remove redundant assertions.
- Properly check for NULL pointers.
- No real need to keep track whether the internal event handler is installed.
- Add a missing function to pass possible extra information associated with
an event. Mentioned in the specification.
for the first swap partition use type sw,dp instead of sw, so dump device
gets configured correctly if swap is not on the second partition.
Fixes PR install/42148.
