2008-05-10BKL: revert back to the old spinlock implementationLinus Torvalds
The generic semaphore rewrite had a huge performance regression on AIM7 (and potentially other BKL-heavy benchmarks) because the generic semaphores had been rewritten to be simple to understand and fair. The latter, in particular, turns a semaphore-based BKL implementation into a mess of scheduling. The attempt to fix the performance regression failed miserably (see the previous commit 00b41ec2611dc98f87f30753ee00a53db648d662 'Revert "semaphore: fix"'), and so for now the simple and sane approach is to instead just go back to the old spinlock-based BKL implementation that never had any issues like this. This patch also has the advantage of being reported to fix the regression completely according to Yanmin Zhang, unlike the semaphore hack which still left a couple percentage point regression. As a spinlock, the BKL obviously has the potential to be a latency issue, but it's not really any different from any other spinlock in that respect. We do want to get rid of the BKL asap, but that has been the plan for several years. These days, the biggest users are in the tty layer (open/release in particular) and Alan holds out some hope: "tty release is probably a few months away from getting cured - I'm afraid it will almost certainly be the very last user of the BKL in tty to get fixed as it depends on everything else being sanely locked." so while we're not there yet, we do have a plan of action.

2008-05-10Revert "semaphore: fix"Linus Torvalds
This reverts commit bf726eab3711cf192405d21688a4b21e07b6188a, as it has been reported to cause a regression with processes stuck in __down(), apparently because some missing wakeup. Quoth Sven Wegener: "I'm currently investigating a regression that has showed up with my last git pull yesterday. Bisecting the commits showed bf726e "semaphore: fix" to be the culprit, reverting it fixed the issue. Symptoms: During heavy filesystem usage (e.g. a kernel compile) I get several compiler processes in uninterruptible sleep, blocking all i/o on the filesystem. System is an Intel Core 2 Quad running a 64bit kernel and userspace. Filesystem is xfs on top of lvm. See below for the output of sysrq-w." See http://lkml.org/lkml/2008/5/10/45 for full report. In the meantime, we can just fix the BKL performance regression by reverting back to the good old BKL spinlock implementation instead, since any sleeping lock will generally perform badly, especially if it tries to be fair.

2008-05-10x86: sysfs cpu?/topology is empty in 2.6.25 (32-bit Intel system)Vaidyanathan Srinivasan
System topology on intel based system needs to be exported for non-numa case as well. All parts of asm-i386/topology.h has come under #ifdef CONFIG_NUMA after the merge to asm-x86/topology.h /sys/devices/system/cpu/cpu?/topology/* is populated based on ENABLE_TOPO_DEFINES The sysfs cpu topology is not being populated on my dual socket dual core xeon 5160 processor based (x86 32 bit) system. CONFIG_NUMA is not set in my case yet the topology is relevant and useful. irqbalance daemon application depends on topology to build the cpus and package list and it fails on Fedora9 beta since the sysfs topology was not being populated in the 2.6.25 kernel. I am not sure if it was intentional to not define ENABLE_TOPO_DEFINES for non-numa systems. This fix has been tested on the above mentioned dual core, dual socket system.

2008-05-10x86: revert commit 709f744 ("x86: bitops asm constraint fixes")Simon Holm Thøgersen
709f744 causes my computer to freeze during the start up of X and my login manger (GDM). It gets to the point where it has shown the default X mouse cursor logo (a big X / cross) and does not respond to anything from that point on. This worked fine before 709f744, and it works fine with 709f744 reverted on top of Linus' current tree (f74d505). The revert had conflicts, as far as I can tell due to white space changes. The diff I ended up with is below. It is 100% reproducible. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-05-10x86: restrict keyboard io ports reservation to make ipmi driver workHelge Wagner
On some of our (single board computer) boards (x86) we are using an IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard controller style) IPMI system interface. Trying to load the openipmi driver fails, because the ports (0x62/0x66) are reserved for keyboard. keyboard reserves the full range 0x60-0x6F while it doesn't need to. Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad controller instead of 0x60-0x6F to allow the openipmi driver to work.

2008-05-09module: don't ignore vermagic string if module doesn't have modversionsRusty Russell
Linus found a logic bug: we ignore the version number in a module's vermagic string if we have CONFIG_MODVERSIONS set, but modversions also lets through a module with no __versions section for modprobe --force (with tainting, but still). We should only ignore the start of the vermagic string if the module actually *has* crcs to check. Rather than (say) having an entertaining hissy fit and creating a config option to work around the buggy code.

2008-05-09module: be more picky about allowing missing module versionsRusty Russell
We allow missing __versions sections, because modprobe --force strips it. It makes less sense to allow sections where there's no version for a specific symbol the module uses, so disallow that.

2008-05-09module: put modversions in vermagicRusty Russell
Don't allow a module built without versions altogether to be inserted into a kernel which expects modversions. modprobe --force will strip vermagic as well as modversions, so it won't be effected, but this will make sure that a non-CONFIG_MODVERSIONS module won't be accidentally inserted into a CONFIG_MODVERSIONS kernel.

2008-05-09[POWERPC] Document when printk is useableBenjamin Herrenschmidt
When debugging early boot problems, it's common to sprinkle printk's all over the place. However, on 64-bit powerpc, this can lead to memory corruption if done too early due to the PACA pointer and lockdep core not being initialized. This adds some comments to early_setup() that document when it is safe to do so in order to save time for whoever has to debug that stuff next.
