* usb: phy: ab8500-usb: update irq handling codeFabio Baltieri2013-03-18
| | | | | | | | | | | | | | Update irq handling code to notify all possible link status changes of AB8500 and AB8505 to the ux500-musb glue driver. The additional event codes will be used for pm-runtime implementation, and are defined in a separate ux500-specific header. This also modify the irq registration code to use devm_* helpers and drop all non necessary fail path code.

* usb: phy: return -ENXIO when PHY layer isn't enabledFelipe Balbi2013-03-18
| | | | | | | | | | | | | | | | in cases where PHY layer isn't enabled, we want to still return an error code (actually an error pointer) so that our users don't need to cope with either error pointer of NULL.

* usb: phy: introduce ->set_vbus() methodFelipe Balbi2013-03-18
| | | | | | | | | | | | | | | | | | | | | this method will be used to enable or disable the charge pump. Whenever we have DRD devices, we need to be able to turn VBUS on or off whenever we want. Note that in the ideal case, this would be controlled by the ID-pin Interrupt, but not all devices have ID-pin properly routed since manufacturers can choose to save that trace if they're building a host-only product out of a DRD IP. This is also useful during debugging where we might not have the proper cable hanging around. Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: gadget: udc-core: allow udc class register gadget deviceFelipe Balbi2013-03-18
| | | | | | | | | | | | | | | | | | | | | Currently all UDC drivers are calling device_register() before calling usb_add_gadget_udc(). In order to avoid code duplication, we can allow udc-core.c register that device. However that would become a really large patch, so to cope with the meanwhile and allow us to write bite-sized patches, we're adding a flag which will be set by UDC driver once it removes the code for registering the gadget device. Once all are converted, the new flag will be removed. Reviewed-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

The patch here moves two defines from asm-generic/atomic.h to asm-generic/cmpxchg.h to make things work as they should. - The VIRT_TO_BUS selector was added for OpenRISC, but OpenRISC does not have the virt_to_bus methods, so there's a patch to remove it again. * tag 'for-3.9-rc3' of git://openrisc.net/jonas/linux: openrisc: remove HAVE_VIRT_TO_BUS asm-generic: move cmpxchg*_local defs to cmpxchg.h openrisc: require gpiolib

* | | perf,x86: fix kernel crash with PEBS/BTS after suspend/resumeStephane Eranian2013-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a kernel crash when using precise sampling (PEBS) after a suspend/resume. Turns out the CPU notifier code is not invoked on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly by the kernel and keeps it power-on/resume value of 0 causing any PEBS measurement to crash when running on CPU0. The workaround is to add a hook in the actual resume code to restore the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0, the DS_AREA will be restored twice but this is harmless.

This is OK for normal lock-based use because in that case, the pointer cannot change. However, when the pointer is protected by RCU (as in "rcu_dereference(p)"), then the pointer can change at any time. This use case can result in the following sequence of events: 1. CPU 0 invokes hlist_entry_safe(), fetches the RCU-protected pointer as sees that it is non-NULL. 2. CPU 1 invokes hlist_del_rcu(), deleting the entry that CPU 0 just fetched a pointer to. Because this is the last entry in the list, the pointer fetched by CPU 0 is now NULL. 3. CPU 0 refetches the pointer, obtains NULL, and then gets a NULL-pointer crash. This commit therefore applies gcc's "({ })" statement expression to create a temporary variable so that the specified pointer is fetched only once, avoiding the above sequence of events. Please note that it is the caller's responsibility to use rcu_dereference() as needed. This allows RCU-protected uses to work correctly without imposing any additional overhead on the non-RCU case.

The problem we are hitting is that the module xen-acpi-processor which uses the ACPI's functions: acpi_processor_register_performance, acpi_processor_preregister_performance, and acpi_processor_notify_smm fails at acpi_processor_register_performance with -22. Note that earlier during bootup in arch/x86/xen/setup.c there is also an call to cpufreq's API: disable_cpufreq(). This is b/c we want the Linux kernel to parse the ACPI data, but leave the cpufreq decisions to the hypervisor. In v3.9 all the checks that d5aaffa9dd531c978c6f3fea06a2972653bd7fc8 added are now hit and the calls to cpufreq_register_notifier will now fail. This means that acpi_processor_ppc_init ends up printing: "Warning: Processor Platform Limit not supported" and the acpi_processor_ppc_status is not set. The repercussions of that is that the call to acpi_processor_register_performance fails right away at: if (!(acpi_processor_ppc_status & PPC_REGISTERED)) and we don't progress any further on parsing and extracting the _P* objects. The only reason the Xen code called that function was b/c it was exported and the only way to gather the P-states. But we can also just make acpi_processor_get_performance_info be exported and not use acpi_processor_register_performance. This patch does so. Acked-by: Rafael J.

A common practice is to build all of the kernel code and leave code that is not commonly needed as modules, with the result that many users are exposed to any bug anywhere in the kernel. Looking for filesystems with a fs- prefix limits the pool of possible modules that can be loaded by mount to just filesystems trivially making things safer with no real cost. Using aliases means user space can control the policy of which filesystem modules are auto-loaded by editing /etc/modprobe.d/*.conf with blacklist and alias directives. Allowing simple, safe, well understood work-arounds to known problematic software. This also addresses a rare but unfortunate problem where the filesystem name is not the same as it's module name and module auto-loading would not work. While writing this patch I saw a handful of such cases. The most significant being autofs that lives in the module autofs4. This is relevant to user namespaces because we can reach the request module in get_fs_type() without having any special permissions, and people get uncomfortable when a user specified string (in this case the filesystem type) goes all of the way to request_module. After having looked at this issue I don't think there is any particular reason to perform any filtering or permission checks beyond making it clear in the module request that we want a filesystem module. The common pattern in the kernel is to call request_module() without regards to the users permissions. In general all a filesystem module does once loaded is call register_filesystem() and go to sleep. Which means there is not much attack surface exposed by loading a filesytem module unless the filesystem is mounted. In a user namespace filesystems are not mounted unless .fs_flags = FS_USERNS_MOUNT, which most filesystems do not set today.

What USB actually needs, though, is to call usb_acpi_find_device() for USB ports that don't have a bus type defined, but have usb_port_device_type as their device type, as well as for USB devices. To fix that replace the struct bus_type pointer in struct acpi_bus_type used for matching devices to specific subsystems with a .match() callback to be used for this purpose and update the users of struct acpi_bus_type, including USB, accordingly. Define the .match() callback routine for USB, usb_acpi_bus_match(), in such a way that it will cover both USB devices and USB ports and remove the now redundant .find_bridge() callback pointer from usb_acpi_bus.
