Just a Kbuild subtlety, not listing a target file inside targets causes it to be rebuilt each time, and as a consequence everything depending on it is rebuilt. Signed-off-by:

With Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Revert the following patch, because of miscompilation problems in different environments leading to UML not working *at all* in TT mode; it was merged lately in 2.6 development cycle, a little after being written, and has caused problems to lots of people; I know it's a bit too long, but it shouldn't have been merged in first place, so I still apply for inclusion in the -stable tree. Anyone using this feature currently is either using some older kernel (some reports even used 2.6.12-rc4-mm2) or using this patch, as included in my -bs patchset. For now there's not yet a fix for this patch, so for now the best thing is to drop it (which was widely reported to give a working kernel, and as such was even merged in -stable tree). "Convert the boot-time host ptrace testing from clone to fork. They were essentially doing fork anyway. This cleans up the code a bit, and makes valgrind a bit happier about grinding it."

This patch is an attempt to fix deadlocks discovered in the core dm. The problems boil down to md->lock having to be held in too many places, so I've split it into two: md->suspend_lock and md->io_lock. suspend_lock is now held throughout dm_suspended() as well as dm_resume() and dm_swap_table() so that these functions cannot run concurrently: there's no requirement for that and it added complexity. DMF_FS_LOCKED becomes redundant: DMF_SUSPENDED provides adequate protection. Signed-Off-By:

Some code tidy-ups in preparation for the next patches. Change dm_table_pre/postsuspend_targets to accept NULL. Use dm_suspended() throughout. Signed-Off-By:

While booting with SMT disabled in bios, when using acpi srat to setup cpu_to_node[], sparse apic_ids create problems. Without this patch, intel x86_64 boxes with hyperthreading disabled in the bios (and which rely on srat for numa setup) endup having incorrect values in cpu_to_node[] arrays, causing sched domains to be built incorrectly etc. Signed-off-by:

This patch eliminates the GCC4 warning on the x86_64 platform: kernel/sched.c:1824: warning: control may reach end of non-void function 'sched_find_first_bit' being inlined. The change follows the lead of others, i.e. it is guaranteed that at least one of b[0], b[1], or b[2] will have a bit set and evaluate to true. That being said, GCC4.0.0 notices that the code flow does not return anything if b[0], b[1] and b[2] are not true. Since we know better, if it's not b[0] or b[1], it has to be b[2]. Signed-off-by:

Save a byte here and there. Ultimatively useless, but these things always catch my eyes when reading the code so just fix them for now. Also I got at least one patch fixing of them already, which gives a good excuse. Signed-off-by:

Icecream preprocesses c sources locally, and sends the result off to a remote host for compiling. It does not recognize includes at assembler level. The fix is to put the assemberincludes an a separate .s file, which will always be assembled locally. Signed-off-by:

This patch will create machinecheck sysdev directories per CPU. All of the cpus still share the same ctl banks. When compiled with CONFIG_HOTPLUG_CPU, it will also bring up/down sysdev directories as cpus go up/down. I have tested the patch along with CONFIG_HOTPLUG_CPU option on in 2.6.13-rc1 kernel.

When the x86_64 cpu hotplug changes went in it added a check in default_do_nmi() which kills NMI delivery on any CPU but the BSP. The NMI watchdog is brought up quite some time before the online bit is set in num_online_cpus so this won't work very well. The nmi watchdogs on cpus that are not BSP will never be reprogrammed and no NMIs. Why was this check added? How does an offlined cpu receive an NMI? Signed-off-by:

I ran glade-2 on the glade file, fixed two missing stock icons and cleaned up the C code that inserts the single/split/full modes. The rest of the patch is minor cleanups only. I refrained from using all the included xpm icons in images.c (like qconf.cc does) in favour of using the stock Gtk+ icons instead. Oh, yes there was a "back" bug in split mode that I also removed, oh well... It has been tested with success by several people, including Jesper Juhl, Randy Dunlap and myself. Signed-off-by:
