* [PATCH] device-mapper: fix md->lock deadlocks in coreAlasdair G Kergon2005-07-29
| | | | | | | | | | | | | | | | | | 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.

* [PATCH] x86_64: fix cpu_to_node setup for sparse apic_idsRavikiran G Thirumalai2005-07-29
| | | | | | | | | | | | | | | 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: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Shai Fultheim <shai@scalex86.org> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] x86_64: Fix gcc 4 warning in sched_find_first_bitJesse Millan2005-07-29
| | | | | | | | | | | | | | | | | | | 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].

* [PATCH] x86_64: cpu hotplug changes kills nmi watchdogAlexander Nyberg2005-07-29
| | | | | | | | | | | | | | | | | | | 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?

* [PATCH] fix gconfig crashJoachim Nilsson2005-07-28
| | | | | | | | | | | | | | | 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.

* Revert broken "statement with no effect" warning fixLinus Torvalds2005-07-28
| | | | | | | | | | It may shut up gcc, but it also incorrectly changes the semantics of the smp_call_function() helpers. You can fix the warning other ways if you are interested (create another inline function that takes no arguments and returns zero), but preferably gcc just shouldn't complain about unused return values from statement expressions in the first place.
