Fix potential NULL pointer dereference in edac_unregister_sysfs() on system boot introduced in 3.6-rc1. Since commit 7a623c03 ("edac: rewrite the sysfs code to use struct device") edac_mc_alloc() no longer initializes embedded kobjects in struct mem_ctl_info. Therefore edac_mc_free() can no longer simply decrement a kobject reference count to free the allocated memory unless the memory controller driver module had also called edac_mc_add_mc(). Now edac_mc_free() will check if the newly embedded struct device has been registered with sysfs before using either the standard device release functions or freeing the data structures itself with logic pulled out of the error path of edac_mc_alloc(). The BUG this patch resolves for me: BUG: unable to handle kernel NULL pointer dereference at (null) EIP is at __wake_up_common+0x1a/0x6a Process modprobe (pid: 933, ti=f3dc6000 task=f3db9520 task.ti=f3dc6000) Call Trace: complete_all+0x3f/0x50 device_pm_remove+0x23/0xa2 device_del+0x34/0x142 edac_unregister_sysfs+0x3b/0x5c [edac_core] edac_mc_free+0x29/0x2f [edac_core] e7xxx_probe1+0x268/0x311 [e7xxx_edac] e7xxx_init_one+0x56/0x61 [e7xxx_edac] local_pci_probe+0x13/0x15 ...

coccinelle warns about: + drivers/edac/edac_mc.c:429:9-23: ERROR: reference preceded by free on line 429 421 if (mci->csrows) { > 422 for (chn = 0; chn < tot_channels; chn++) { 423 csr = mci->csrows[chn]; 424 if (csr) { > 425 for (chn = 0; chn < tot_channels; chn++) 426 kfree(csr->channels[chn]); 427 kfree(csr); 428 } > 429 kfree(mci->csrows[i]); 430 } 431 kfree(mci->csrows); 432 } and that code block seem to mess things up in several ways (double free, memory leak, out-of-bound reads etc.): L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be "row" and "tot_csrows" respectively. Which means either memory leak, or out-of-bound reads (which if does not trigger an immediate page fault error, will further lead to kfree() on random addresses). L425: The inner loop is reusing the same iterator "chn" as the outer loop, which could lead to premature end of the outer loop, and hence memory leak. L429: The array index 'i' in mci->csrows[i] is a temporary value used in previous loops, and won't change at all in the current loop. Which means either out-of-bound read and possibly kfree(random number), or the same mci->csrows[i] get freed once and again, and possibly double free for the kfree(csr) in L427. L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory. The buggy code was introduced by commit de3910eb ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1 merge window. Fix it by freeing up resources in this order: free csrows[i]->channels[j] free csrows[i]->channels free csrows[i] free csrows CC: Mauro Carvalho Chehab <mchehab@redhat.com> CC: Shaun Ruffell <sruffell@digium.com> Signed-off-by: NFengguang Wu <fengguang.wu@intel.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

coretemp_init loops with for_each_online_cpu, adding platform_devices and sysfs interfaces, then calls register_hotcpu_notifier. There is a race if a CPU is offlined or onlined after the loop, but before register_hotcpu_notifier. The race might result in the absence of a platform_device+sysfs interface for an online CPU, or the presence of a platform_device+sysfs interface for an offline CPU. A similar race occurs during coretemp_exit, after the module calls unregister_hotcpu_notifier, but before it unregisters all devices, a CPU might offline and a device for an offline CPU will exist for a short while. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus. Build tested. Signed-off-by: NSilas Boyd-Wickizer <sbw@mit.edu> Signed-off-by: NJean Delvare <khali@linux-fr.org>

via_cputemp_init loops with for_each_online_cpu, adding platform_devices, then calls register_hotcpu_notifier. If a CPU is offlined between the loop and register_hotcpu_notifier, then later onlined, via_cputemp_device_add will attempt to add platform devices with the same ID. A similar race occurs during via_cputemp_exit, after the module calls unregister_hotcpu_notifier, a CPU might offline and a device will exist for a CPU that is offline. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus.

Pull ARM and clkdev fixes from Russell King: "Two patches for clkdev which resolve the long standing issue that the devm_* versions were dependent on clkdev, which they shouldn't have been. Instead, they're dependent on HAVE_CLK instead, which implies that you're providing clk_get() and clk_put(). A small fix to the ARM decompressor to ensure that the page tables are properly interpreted by the CPU, and reserve syscall 378 for kcmp (the checksyscalls.sh script is unfortunately currently broken so arch maintainers aren't getting notified of new syscalls...) Lastly, a larger fix for an issue between the common clk subsystem and smp_twd which causes warnings to be spat out." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: reserve syscall 378 for kcmp ARM: 7535/1: Reprogram smp_twd based on new common clk framework notifiers ARM: 7537/1: clk: Fix release in devm_clk_put() ARM: 7532/1: decompressor: reset SCTLR.TRE for VMSA ARMv7 cores ARM: 7534/1: clk: Make the managed clk functions generically available
