This patch fixes a bug, (wrongfully) resetting the value of LPC32XX_CLKPWR_MS_CTRL back to its initial contents (after careful setup). This was discovered only with a board/bootloader combination (EA3250) where the contents of the respective register wasn't already at the correct value on Linux boot.

If the privileges given to root threads (3% of allowable memory) or a negative value of /proc/pid/oom_score_adj happen to exceed the amount of rss of a thread, its badness score overflows as a result of commit a7f638f9 ("mm, oom: normalize oom scores to oom_score_adj scale only for userspace"). Fix this by making the type signed and return 1, meaning the thread is still eligible for kill, if the value is negative.

This reverts commit 9e612a00. It incorrectly finds VGA connectors where none are attached, apparently not noticing that nothing replied to the EDID queries, and happily using the default EDID modes that have nothing to do with actual hardware. That in turn then causes X to fall down to the lowest common denominator, which is usually the default 1024x768 mode that is in the default EDID and pretty much anything supports). I'd suggest that if not relying on the HDP pin, the code should at least check whether it gets valid EDID data back, rather than just assume there's something on the VGA connector.

This reverts commit 7732a557 (and commit 3f50fff4, which was a follow-up cleanup). We're chasing an elusive bug that Dave Jones can apparently reproduce using his system call fuzzer tool, and that looks like some kind of locking ordering problem on the directory i_mutex chain. Our i_mutex locking is rather complex, and depends on the topological ordering of the directories, which is why we have been very wary of splicing directory entries around. Of course, we really don't want to ever see aliased unconnected directories anyway, so none of this should ever happen, but this revert aims to basically get us back to a known older state. Bruce points to some of the previous discussion at http://marc.info/?i=<20110310105821.GE22723@ZenIV.linux.org.uk> and in particular a long post from Neil: http://marc.info/?i=<20110311150749.2fa2be66@notabene.brown> It should be noted that it's possible that Dave's problems come from other changes altohgether, including possibly just the fact that Dave constantly is teachning his fuzzer new tricks. So what appears to be a new bug could in fact be an old one that just gets newly triggered, but reverting these patches as "still under heavy discussion" is the right thing regardless.
