- when yielding the cpu while using the vnode's page list, use a marker page
to keep our place in the list (like the other cases where we drop the lock).
- wait until no one else has the page busy before deciding if the page needs
to be cleaned. a page will be dirty while it's being initialized but will
be marked clean before PG_BUSY is cleared.
both found by enami.
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
just add the additional commands to the `.configure_done' target.
Also, since the groff distribution Makefiles don't get their dependencies
right, use internal knowledge to add additional target ordering to the
generated makefile. Note, this hack can be removed once our own make(1)
can be invoked in true sequential (i.e. compatible) mode again for subdir
makes.
- bug with order in args in mask conversion md code.
- flags can be both int and long on the alpha. kludge around that, by not
passing pointers to the conversion function.
- something is wrong with the toolchain look at the void * cast in copyout().
- sa_restorer is in a different place on the aplha. Deal with that, by not
initializing it as before. XXX: this should be changed in the MD signal
definition.
* Beef up that goo so that for each ".WAIT group" all of the install targets
in the previous group have completed before starting the `all', `depend'
or `dependall' targets.
