an initiator/target nexus and thus mark the correct queue (if any) a
command is on.
* If a disconnected command times out, just leave it on the nexus queue
and do nothing (for now). I need yet to decide on the strategy to
follow in this case. Note: we used to move the command to the `ready'
queue and then do nothing, which is worse.
merge (ints -> longs). The only platform on which this might have caused
a problem is the Alpha, and it happens to be safe because the first 6 arguments
are passed in registers on the Alpha (and are thus implicitly promoted to
longs anyhow).
valid bit. This is faster than the "unmap all" solution that were described
in that Mach paper _and_ it eliminates the need for checking the wired bit.
As a result of this; swapping started working again on vax :-)
string. The actual functional changes are:
1. in vm_page_alloc(), restore some long lost code by Paul Kranenburg
that reserves the last few pages for kernel objects, adding an
additional escape for the pageout daemon.
2. In vm_wait() (replaces VM_WAIT), recognize the amusing fatal
deadlock where the pagedemon sleeps on a channel that only it ever
wakes up, and add a timeout and printf. Mod 1 should generally
prevent this from happening in any case.
3. Fix a livelock in vm_pageout_page() caused by a pre-wakeup of
page consumers prior to the pageout, which can easily fail over
memory issues in NFS and IP code. Also, ++ cnt.v_pageouts only
if the pageout succeeded.
bus_dma's appearance in the tree) to support sram bounce buffers.
When a busified if_de.c appears, this module can join awd.c at the
end of that long walk on a short pier.
AC_SUBST to configure the PSIM simulator. Add an comment noting that
these files are now obsolete (they are different from the ppc*-eabi.mt
files only by this comment).
characters escaped with a backslash, but recognise the backslashes for
backwards compatibility. When matching names, do any escaping of
the regexp '.' metacharacter automatically, if needed.
When a shared object dependency is printed out, use a form that does
not have the backslashes in it, for readability.
Print out the full pathname of the matching shared object, for clarity.
