There is an issue when memcg unregisters events that were attached to the same eventfd: - On the first call mem_cgroup_usage_unregister_event() removes all events attached to a given eventfd, and if there were no events left, thresholds->primary would become NULL; - Since there were several events registered, cgroups core will call mem_cgroup_usage_unregister_event() again, but now kernel will oops, as the function doesn't expect that threshold->primary may be NULL. That's a good question whether mem_cgroup_usage_unregister_event() should actually remove all events in one go, but nowadays it can't do any better as cftype->unregister_event callback doesn't pass any private event-associated cookie. So, let's fix the issue by simply checking for threshold->primary. FWIW, w/o the patch the following oops may be observed: BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 Pid: 574, comm: kworker/0:2 Not tainted 3.3.0-rc4+ #9 Bochs Bochs RIP: 0010:[<ffffffff810be32c>] [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 RSP: 0018:ffff88001d0b9d60 EFLAGS: 00010246 Process kworker/0:2 (pid: 574, threadinfo ffff88001d0b8000, task ffff88001de91cc0) Call Trace: [<ffffffff8107092b>] cgroup_event_remove+0x2b/0x60 [<ffffffff8103db94>] process_one_work+0x174/0x450 [<ffffffff8103e413>] worker_thread+0x123/0x2d0 Cc: stable <stable@vger.kernel.org> Signed-off-by: NAnton Vorontsov <anton.vorontsov@linaro.org> Acked-by: NKAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Kirill A.

With kernel 3.1, Christoph removed i_alloc_sem and replaced it with calls (namely inode_dio_wait() and inode_dio_done()) which are EXPORT_SYMBOL_GPL() thus they cannot be used by non-GPL file systems and further inode_dio_wait() was pushed from notify_change() into the file system ->setattr() method but no non-GPL file system can make this call. That means non-GPL file systems cannot exist any more unless they do not use any VFS functionality related to reading/writing as far as I can tell or at least as long as they want to implement direct i/o. Both Linus and Al (and others) have said on LKML that this breakage of the VFS API should not have happened and that the change was simply missed as it was not documented in the change logs of the patches that did those changes. This patch changes the two function exports in question to be EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible for all modules. Christoph, who introduced the two functions and exported them GPL-only is CC-ed on this patch to give him the opportunity to object to the symbols being changed in this manner if he did indeed intend them to be GPL-only and does not want them to become available to all modules.

This fixes: - We kept interrupts soft-disabled when schedule'ing or calling do_signal when returning to userspace as a result of a hardware interrupt. - Rename do_signal to do_notify_resume like all other archs (and do_signal_pending back to do_signal, which it was before Roland changed it). - Add the missing call to key_replace_session_keyring() to do_notify_resume().

The 'poll()' system call timeout parameter is supposed to be 'int', not 'long'. Now, the reason this matters is that right now 32-bit compat mode is broken on at least x86-64, because the 32-bit code just calls 'sys_poll()' directly on x86-64, and the 32-bit argument will have been zero-extended, turning a signed 'int' into a large unsigned 'long' value. We could just introduce a 'compat_sys_poll()' function for this, and that may eventually be what we have to do, but since the actual standard poll() semantics is *supposed* to be 'int', and since at least on x86-64 glibc sign-extends the argument before invocing the system call (so nobody can actually use a 64-bit timeout value in user space _anyway_, even in 64-bit binaries), the simpler solution would seem to be to just fix the definition of the system call to match what it should have been from the very start. If it turns out that somebody somehow circumvents the user-level libc 64-bit sign extension and actually uses a large unsigned 64-bit timeout despite that not being how poll() is supposed to work, we will need to do the compat_sys_poll() approach.

This provides unified readq()/writeq() helper functions for 32-bit drivers. For some cases, readq/writeq without atomicity is harmful, and order of io access has to be specified explicitly. So in this patch, new two header files which contain non-atomic readq/writeq are added. - <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/ writeq with the order of lower address -> higher address - <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/ writeq with reversed order This allows us to remove some readq()s that were added drivers when the default non-atomic ones were removed in commit dbee8a0a ("x86: remove 32-bit versions of readq()/writeq()") The drivers which need readq/writeq but can do with the non-atomic ones must add the line: #include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */ But this will be nop in 64-bit environments, and no other #ifdefs are required. So I believe that this patch can solve the problem of 1. driver-specific readq/writeq 2. atomicity and order of io access This patch is tested with building allyesconfig and allmodconfig as ARCH=x86 and ARCH=i386 on top of tip/master.

This patch (as1521b) fixes the interaction between usb-storage's scanning thread and the freezer. The current implementation has a race: If the device is unplugged shortly after being plugged in and just as a system sleep begins, the scanning thread may get frozen before the khubd task. Khubd won't be able to freeze until the disconnect processing is complete, and the disconnect processing can't proceed until the scanning thread finishes, so the sleep transition will fail. The implementation in the 3.2 kernel suffers from an additional problem. There the scanning thread calls set_freezable_with_signal(), and the signals sent by the freezer will mess up the thread's I/O delays, which are all interruptible. The solution to both problems is the same: Replace the kernel thread used for scanning with a delayed-work routine on the system freezable work queue. Freezable work queues have the nice property that you can cancel a work item even while the work queue is frozen, and no signals are needed. The 3.2 version of this patch solves the problem in Bugzilla #42730.

Merge tag 'for-usb-linus-2012-02-21' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-linus Hi Greg, Here's three bug fixes that should be queued for 3.3. The first fixes an issue we saw with an Intel Panther Point xHCI host, where a certain OSV's custom BIOS would disable the PCI device during boot. It changes the generic PCI quirks handler for all USB host controllers, but in a way both Jesse Barnes and Oliver Neukum have agreed is safe. The second patch is Elric Fu's first kernel patch! Congrats! It fixes a bug in the USB 3.0 hub reset handling. The last patch fixes a bug in the xHCI driver that feeds invalid input to the xHC host. Only the VIA host controller seems to have issues with it. Thanks to Felipe Contreras for testing this patch on his VIA host, and Andiry Xu for suggesting the fix. All three patches are marked for stable. Sarah Sharp

The xHCI 0.96 spec says that HS bulk and control endpoint NAK rate must be encoded as an exponent of two number of microframes. The endpoint descriptor has the NAK rate encoded in number of microframes. We were just copying the value from the endpoint descriptor into the endpoint context interval field, which was not correct. This lead to the VIA host rejecting the add of a bulk OUT endpoint from any USB 2.0 mass storage device. The fix is to use the correct encoding. Refactor the code to convert number of frames to an exponential number of microframes, and make sure we convert the number of microframes in HS bulk and control endpoints to an exponent. This should be back ported to kernels as old as 2.6.31, that contain the commit dfa49c4a "USB: xhci - fix math in xhci_get_endpoint_interval" Signed-off-by: NSarah Sharp <sarah.a.sharp@linux.intel.com> Tested-by: NFelipe Contreras <felipe.contreras@gmail.com> Suggested-by: NAndiry Xu <andiry.xu@amd.com> Cc: stable@vger.kernel.org

The superspeed device attached to a USB 3.0 hub(such as VIA's) doesn't respond the address device command after resume. The root cause is the superspeed hub will miss the Hub Depth value that is used as an offset into the route string to locate the bits it uses to determine the downstream port number after reset, and all packets can't be routed to the device attached to the superspeed hub. Hub driver sends a Set Hub Depth request to the superspeed hub except for USB 3.0 root hub when the hub is initialized and doesn't send the request again after reset due to the resume process. So moving the code that sends the Set Hub Depth request to the superspeed hub from hub_configure() to hub_activate() is to cover those situations include initialization and reset. The patch should be backported to kernels as old as 2.6.39.

On some systems with an Intel Panther Point xHCI host controller, the BIOS disables the xHCI PCI device during boot, and switches the xHCI ports over to EHCI. This allows the BIOS to access USB devices without having xHCI support. The downside is that the xHCI BIOS handoff mechanism will fail because memory mapped I/O is not enabled for the disabled PCI device. Jesse Barnes says this is expected behavior. The PCI core will enable BARs before quirks run, but it will leave it in an undefined state, and it may not have memory mapped I/O enabled. Make the generic USB quirk handler call pci_enable_device() to re-enable MMIO, and call pci_disable_device() once the host-specific BIOS handoff is finished. This will balance the ref counts in the PCI core. When the PCI probe function is called, usb_hcd_pci_probe() will call pci_enable_device() again. This should be back ported to kernels as old as 2.6.31. That was the first kernel with xHCI support, and no one has complained about BIOS handoffs failing due to memory mapped I/O being disabled on other hosts (EHCI, UHCI, or OHCI).

The xfs checks quota when reserving disk blocks and inodes. In the block reservation, it checks if the total number of blocks including current usage and new reservation exceed quota. In the inode reservation, it checks using the total number of inodes including only current usage without new reservation. However, this inode quota check works well since the caller of xfs_trans_dquot() always sets the argument of the number of new inode reservation to 1 or 0 and inode is reserved one by one in current xfs. To make it more general, this patch changes it to the same way as the block quota check.

These files aren't built when PM_OPP is disabled, causing the following build errors at link time: twl-common.c:(.init.text+0x2e48): undefined reference to `omap34xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e4c): undefined reference to `omap34xx_vddcore_volt_data' twl-common.c:(.init.text+0x2e5c): undefined reference to `omap36xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e60): undefined reference to `omap36xx_vddcore_volt_data' twl-common.c:(.init.text+0x2830): undefined reference to `omap44xx_vdd_mpu_volt_data' twl-common.c:(.init.text+0x283c): undefined reference to `omap44xx_vdd_iva_volt_data' twl-common.c:(.init.text+0x2844): undefined reference to `omap44xx_vdd_core_volt_data' Acked-by: NKevin Hilman <khilman@ti.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

The patch series to re-factor PCI's 'latency timer' setup (re: http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to remove the ARM specific definition of 'pcibios_max_latency' once such had been moved into the pci core resulting in ARM related compile errors - drivers/built-in.o:(.data+0x230): multiple definition of `pcibios_max_latency' arch/arm/common/built-in.o:(.data+0x40c): first defined here make[1]: *** [vmlinux.o] Error 1 In the series, patch 2/16 (commit 168c8619) converted the ARM specific version of 'pcibios_set_master()' to a non-inlined version. This was done in preperation for hosting it up into PCI's core, which was done in patch 10/16 (commit 96c55900) of the series (and where the removal of ARM's 'pcibios_max_latency' was overlooked).

Current ARM local timer code registers CPUFREQ notifiers even in case the twd_timer_setup() isn't called. That seems to be wrong and would eventually lead to kernel crash on the CPU frequency transitions on the SOCs where the local timer doesn't exist or broken because of hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt). The issue was observed with v3.3-rc3 and building an OMAP2+ kernel on OMAP3 SOC which doesn't have TWD. Below is the dump for reference : Unable to handle kernel paging request at virtual address 007e900 pgd = cdc20000 [007e9000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP Modules linked in: CPU: 0 Not tainted (3.3.0-rc3-pm+debug+initramfs #9) PC is at twd_update_frequency+0x34/0x48 LR is at twd_update_frequency+0x10/0x48 pc : [<c001382c>] lr : [<c0013808>] psr: 60000093 sp : ce311dd8 ip : 00000000 fp : 00000000 r10: 00000000 r9 : 00000001 r8 : ce310000 r7 : c0440458 r6 : c00137f8 r5 : 00000000 r4 : c0947a74 r3 : 00000000 r2 : 007e9000 r1 : 00000000 r0 : 00000000 Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment usr Control: 10c5387d Table: 8dc20019 DAC: 00000015 Process sh (pid: 599, stack limit = 0xce3102f8) Stack: (0xce311dd8 to 0xce312000) 1dc0: 6000c 1de0: 00000001 00000002 00000000 00000000 00000000 00000000 00000 1e00: ffffffff c093d8f0 00000000 ce311ebc 00000001 00000001 ce310 1e20: c001386c c0437c4c c0e95b60 c0e95ba8 00000001 c0e95bf8 ffff4 1e40: 00000000 00000000 c005ef74 ce310000 c0435cf0 ce311ebc 00000 1e60: ce352b40 0007a120 c08d5108 c08ba040 c08ba040 c005f030 00000 1e80: c08bc554 c032fe2c 0007a120 c08d4b64 ce352b40 c08d8618 ffff8 1ea0: c08ba040 c033364c ce311ecc c0433b50 00000002 ffffffea c0330 1ec0: 0007a120 0007a120 22222201 00000000 22222222 00000000 ce357 1ee0: ce3d6000 cdc2aed8 ce352ba0 c0470164 00000002 c032f47c 00034 1f00: c0331cac ce352b40 00000007 c032f6d0 ce352bbc 0003d090 c0930 1f20: c093d8bc c03306a4 00000007 ce311f80 00000007 cdc2aec0 ce358 1f40: ce8d20c0 00000007 b6fe5000 ce311f80 00000007 ce310000 0000c 1f60: c000de74 ce987400 ce8d20c0 b6fe5000 00000000 00000000 0000c 1f80: 00000000 00000000 001fbac8 00000000 00000007 001fbac8 00004 1fa0: c000df04 c000dd60 00000007 001fbac8 00000001 b6fe5000 00000 1fc0: 00000007 001fbac8 00000007 00000004 b6fe5000 00000000 00202 1fe0: 00000000 beb565f8 00101ffc 00008e8c 60000010 00000001 00000 [<c001382c>] (twd_update_frequency+0x34/0x48) from [<c008ac4c>] ) [<c008ac4c>] (smp_call_function_single+0x17c/0x1c8) from [<c0013) [<c0013890>] (twd_cpufreq_transition+0x24/0x30) from [<c0437c4c>) [<c0437c4c>] (notifier_call_chain+0x44/0x84) from [<c005efe4>] () [<c005efe4>] (__srcu_notifier_call_chain+0x70/0xa4) from [<c005f) [<c005f030>] (srcu_notifier_call_chain+0x18/0x20) from [<c032fe2) [<c032fe2c>] (cpufreq_notify_transition+0xc8/0x1b0) from [<c0333) [<c033364c>] (omap_target+0x1b4/0x28c) from [<c032f47c>] (__cpuf) [<c032f47c>] (__cpufreq_driver_target+0x50/0x64) from [<c0331d24) [<c0331d24>] (cpufreq_set+0x78/0x98) from [<c032f6d0>] (store_sc) [<c032f6d0>] (store_scaling_setspeed+0x5c/0x74) from [<c03306a4>) [<c03306a4>] (store+0x58/0x74) from [<c014d868>] (sysfs_write_fi) [<c014d868>] (sysfs_write_file+0x80/0xb4) from [<c00f2c2c>] (vfs) [<c00f2c2c>] (vfs_write+0xa8/0x138) from [<c00f2e9c>] (sys_write) [<c00f2e9c>] (sys_write+0x40/0x6c) from [<c000dd60>] (ret_fast_s) Code: e594300c e792210c e1a01000 e5840004 (e7930002) ---[ end trace 5da3b5167c1ecdda ]--- Reported-by: NKevin Hilman <khilman@ti.com> Acked-by: NMarc Zyngier <marc.zyngier@arm.com> Tested-by: NKevin Hilman <khilman@ti.com> Signed-off-by: NSantosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

(And define it properly for x86-32, which had its 'current_task' declaration in separate from x86-64) Bitten by my dislike for modules on the machines I use, and the fact that apparently nobody else actually wanted to test the patches I sent out. Snif. Nobody else cares. Anyway, we probably should uninline the 'kernel_fpu_begin()' function that is what modules actually use and that references this, but this is the minimal fix for now.
