curcpu()->ci_want_resched is now required, so get rid of the
want_resched global. Also, cpu_need_resched() now takes two arguments.
The l_next and l_back fields in struct lwp no longer exists, so delete
references to it from genassym.cf.
Also, m68k/m68k/proc_subr.s is no longer used, says mhitch, so remove its use.
This brings the atari BOOT kernel back to a buildable state.
- don't use void * for pointer arithmetic
- don't try to modify const parameters
A kernel with 'options TCP_SIGNATURE' works as well as it ever did, now.
(ie, clunky, but passable)
the struct tcphdr * argument of tcp_dooptions(). RFC2385 support
(options TCP_SIGNATURE) needs to modify the header during options
processing, and this revision broke it.
OK yamt@.
reference count goes to 0) reclaim of deleted nodes as opposed to
waiting for the system to start reclaiming the freelist
* combine some nodeflags from different variable to one status variable
the kernel it has 0 references to the node in question. In other
words, this can be used to avoid inactive(), or, if the file server
does not implement inactive, prompt reclaim for removed nodes.
as we give a reference to userspace for the puffs_node for the
duration of the poll call. So reference count puffs_node separately
from the parent vnode. vref()/vrele() is not possible due to a possible
surprise visit from VOP_INACTIVE.
loop function might generate some results. and this is still "after"
event handling (except for the first call, but I'm not too keen on
optimizing for that)
* don't be such a baby about EINTR from kevent(). if we get it, suck
it up and continue instead of quitting
called by the MI code.
Implement a way of tracking the vmspace allocated to a process and its
LWPs so that if it changes underneath us we can correct the space id in
the trapframe in pmap_activate for now.
An example of when this happens is vfork/exec.
An exec hook is probably the way to go.
creating a trapframe, with exceptions disabled and using only BANK1
registers. If a valid pte is found, load it and return. Otherwise
create a trapframe and proceed to the full-blown C handler.
shouldn't release resources. As a quick hack to prevent double
frees etc, introduce "dead" variable into fuse channel to signal
if the backing puffs resource was already freed. XXX: the check
is only in exit/unmount currently.
Proper fix really depends on some puffs features I still haven't
gotten around to doing.
