* vm/vm_resident.c (vm_page_grab): Only block unprivileged allocations over vm_page_external_limit if they are actually external allocations. Reported by Mark Kettenis (kettenis@wins.uva.nl>.

* i386/i386at/model_dep.c (init_alloc_aligned): Revert previous change except for the one to AVAIL_NEXT. All the rest of the previous code was correct. Correction from Momchil Velikov (velco@fadata.bg).

Force subdirectory targets so they get recompiled properly. * i386/Makefile.in (linux/linux.o): Depend on FORCE instead of linux. (FORCE): New target. * i386/Makefrag (i386/sysdep.o, FORCE): Likewise.

* linux/dev/drivers/block/genhd.c (check_partition): Change message to say these are only the DOS partitions. * i386/linux/dev/include/linux/autoconf.h (CONFIG_BSD_DISKLABEL, CONFIG_SMD_DISKLABEL): #undef these. The dev/glue/block.c code deals with BSD disklabels and expects the Linux genhd.c code to handle only the DOS partitions; having genhd.c do BSD disklabels too just confuses things.

* i386/i386at/model_dep.c (init_alloc_aligned): Make the checks correctly for addresses falling into skip regions. Reported by Momchil Velikov (velco@fadata.bg).

* i386/linux/Makefile.in: For each .o file in $(linux-objs) include a corresponding .d file, unless `no_deps' is `t'. (make-deps): New function. (%.d): New pattern rules for building %.d from %.c and %.S.

* vm/vm_resident.c (vm_page_grab): Don't bounce requests when vm_page_external_count == vm_page_external_limit, so that before initialization is complete we can still allocate memory without relying on current_thread. (vm_page_wait): Also block if we are over the external page limit. * vm/vm_pageout.c (vm_pageout_scan): Rewrite the scan-for-pages-to-pageout loop to not crash when we hit the end of the inactive queue; instead jump back to the pause-for-a-little-while code.

* linux/dev/drivers/net/Space.c (ethif_probe): Probe tc59x_probe (CONFIG_VORTEX) after el3_probe (CONFIG_EL3), because the latter card matches the former probe, but the driver doesn't work with it. Reported by Marcus Brinkmann <brinkmd@debian.org>.
