at dmamap load time that the mapping will be used for a unidirectional
transfer of the specified direction.

Do more intelligent calculation of KVM size. This reduces the amount of
...
pre-allocated physical memory significantly.
A 11/750, for example, get 2MB more free (of 14MB), about 12%.

Add System V semaphore resource limits to each GENERIC file that has an
...
option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.
options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory
If anyone thinks that this is incorrect for any of these files, please
correct it.
Note - the i386 port was not forgotten. It was done separately.

> More EMODD work:
> - Using CVTDL and subtracting to seperate integer from fraction does
> not work if the integer is >32 bits long; instead, rearrange the bits

> Also:

> - move the zero checks earlier in the routine
>
> - instead of 'ret' in zeroexit, use brw goback
> Switch a "BGTR foo" to a "BLSS bar; BRW foo; bar:". In this case, the
> difference between the BGTR and foo: is too large for a byte displacement.
> as should give an error or at least a warning here, but it doesn't;
