2012-02-02Fix race in process_vm_rw_coreChristopher Yeoh
This fixes the race in process_vm_core found by Oleg (see http://article.gmane.org/gmane.linux.kernel/1235667/ for details). This has been updated since I last sent it as the creation of the new mm_access() function did almost exactly the same thing as parts of the previous version of this patch did. In order to use mm_access() even when /proc isn't enabled, we move it to kernel/fork.c where other related process mm access functions already are.

2012-02-02cgroup: remove cgroup_subsys argument from callbacksLi Zefan
The argument is not used at all, and it's not necessary, because a specific callback handler of course knows which subsys it belongs to. Now only ->pupulate() takes this argument, because the handlers of this callback always call cgroup_add_file()/cgroup_add_files().

2012-02-01drivercore: Output common devicetree information in ueventGrant Likely
When userspace needs to find a specific device, it currently isn't easy to resolve a /sys/devices/ path from a specific device tree node. Nor is it easy to obtain the compatible list for devices. This patch generalizes the code that inserts OF_* values into the uevent device attribute so that any device that is attached to an OF node will have that information exported to userspace. Without this patch only platform devices and some powerpc-specific busses have access to this data. The original function also creates a MODALIAS property for the compatible list, but that code has not been generalized into the common case because it has the potential to break module loading on a lot of bus types. Bus types are still responsible for their own MODALIAS properties. Boot tested on ARM and compile tested on PowerPC and SPARC.

2012-02-01mtd: fix merge conflict resolution breakageArtem Bityutskiy
This patch fixes merge conflict resolution breakage introduced by merge d3712b9dfcf4 ("Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream"). The commit changed 'mtd_can_have_bb()' function and made it always return zero, which is incorrect. Instead, we need it to return whether the underlying flash device can have bad eraseblocks or not. UBI needs this information because it affects how it handles the underlying flash. E.g., if the underlying flash is NOR, it cannot have bad blocks and any write or erase error is fatal, and all we can do is to switch to R/O mode. We do not need to reserve a pool of good eraseblocks for bad eraseblocks handling, and so on. This patch also removes 'mtd_can_have_bb()' invocations from Logfs to ensure correct Logfs behavior. I've tested that with this patch UBI works on top of NOR and NAND flashes emulated by mtdram and nandsim correspondingly. This patch is based on patch from Linus Torvalds.

PROP_MAX_SHIFT should be set to <=32 on 64-bit box. This fixes two bugs in the below lines of bdi_dirty_limit(): bdi_dirty *= numerator; do_div(bdi_dirty, denominator); 1) divide error: do_div() only uses the lower 32 bit of the denominator, which may trimmed to be 0 when PROP_MAX_SHIFT > 32. 2) overflow: (bdi_dirty * numerator) could easily overflow if numerator used up to 48 bits, leaving only 16 bits to bdi_dirty Cc: <stable@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Reported-by: Ilya Tumaykin <librarian_rus@yahoo.com> Tested-by: Ilya Tumaykin <librarian_rus@yahoo.com> Signed-off-by: Wu Fengguang <fengguang.wu@intel.com>
