This reverts commit 59365d13. It turns out that this can break certain existing user land setups. Quoth Sarah Sharp: "On Wednesday, I updated my branch to commit 460781b5 from linus' tree, and my box would not boot. klogd segfaulted, which stalled the whole system. At first I thought it actually hung the box, but it continued booting after 5 minutes, and I was able to log in. It dropped back to the text console instead of the graphical bootup display for that period of time. dmesg surprisingly still works. I've bisected the problem down to this commit (commit 59365d13) The box is running klogd 1.5.5ubuntu3 (from Jaunty). Yes, I know that's old. I read the bit in the commit about changing the permissions of kallsyms after boot, but if I can't boot that doesn't help." So let's just keep the old default, and encourage distributions to do the "chmod -r /proc/kallsyms" in their bootup scripts. This is not worth a kernel option to change default behavior, since it's so easily done in user space.

Frame buffer compression is broken on Ironlake due to buggy hardware. Currently it is disabled through chicken bits, but it still consumes over 1W more than if we simply never attempt to enable the FBC code paths.

Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

Linus Torvalds found that it was rather trivial to trigger a system freeze: In fact, with lockdep, I don't even need to do the sysrq-d thing: it shows the bug as it happens. It's the X server taking the same lock recursively. Here's the problem: ============================================= [ INFO: possible recursive locking detected ] 2.6.37-rc2-00012-gbdbd01ac #7 --------------------------------------------- Xorg/2816 is trying to acquire lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e but task is already holding lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a other info that might help us debug this: 2 locks held by Xorg/2816: #0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a #1: (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b This recursion was introduced by rearranging the locking to avoid the double locking on the fast path (4f27b5d and fbd5a26d) and the introduction of the prefault to encourage the fast paths (b5e4f2b). In order to undo the problem, we rearrange the code to perform the access validation upfront, attempt to prefault and then fight for control of the mutex. the best case scenario where the mutex is uncontended the prefaulting is not wasted.

This really isn't the right thing to do, and strictly speaking we should have the BKL depth count in the thread info right next to the preempt count. The two really do go together. However, since that would involve a patch to all architectures, and the BKL is finally going away, it's simply not worth the effort to do the RightThing(tm). Just re-instate the <linux/sched.h> include that we used to get accidentally from the smp_lock.h one. This is all fallout from the same old "BKL: remove extraneous #include <smp_lock.h>" commit.

In that case the first process should give up trying to reserve and return -EAGAIN.
