havoc if the server erroneously uses the same filehandle for
different files. This changes back revision 1.28; the PR that
that revision fixed doesn't apply anymore, it has been verified
not to be a problem with this change.
the page is wired down. Flushing both halves of a wired TLB entry resulted
in hangs when in programs called for and released kernel memory
soon after being invoked. In particular, we see this when single-stepping
a process using GDB.
It would be better if we could arrange to use both halves of the TLB
entry for the PCB, but for some reason we frequently end up with things
on an odd page boundary.
- move status handling in siop_scsicmd_end(), it's better than in siop_intr()
- define 2 internal SIOP status, for "no status reported by device" and
reset condition
- add a list of "urgent" command, to be executed before the list of command
queued the normal way; this is used for command which got aborted
by a QUEUE FULL and have to be requeued in order.
- Don't accept to send a Q_TAG message not immediatly folowing a IDENTIFY
Install the core of the scheduler in main script (so it's in RAM when there is
one), and avoid jump in the common case. The command part of the scheduler now
lives in host memory, with tables.
Add template for a tag switch.
-shared or -symbolic (as on other platforms). Also, override LIBGCC_SPEC for
all platforms (where it would incorrectly include the .a file explicitly on
some).
This should fix Mozilla on macppc.
calls to swap_bytes() do indeed have non-aligned sources and destinations.
Fixes unaligned access problems on alpha and probably some of our other
architectures.
rm complains because it can't actually nuke the mount point. Anything serious
like permissions or I/O errors will get caught in the install's after this
anyways.
environment variable; since there isn't a standard format provided by the
C library that corresponds to pr's default header format, add a new option
'-T' to take a strftime() format string if desired.
