git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pinctrl update from Linus Walleij: "These are the pinctrl changes for v3.10: - Patrice Chotard contributed a new configuration debugfs interface and reintroduced fine-grained locking into the core: instead of having a "big pinctrl lock" we have a per-controller lock and specialized locks for the global controller and pinctrl handle lists. - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and replaced them with pinctrl-single (which is also used by other SoCs) so we are gaining consolidation. The platform particulars now come in through the device tree. - Haoijan also added support for generic pin config into the pinctrl-single driver which is another big consolidation win. - Finally also GPIO ranges are now supported by the pinctrl-single driver. - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing more of the older Samsung platforms under the pinctrl umbrella and out of arch/arm. - Maxime Ripard contributed new Allwinner A10/A13 drivers. - Sachin Kamat, Wei Yongjun and Axel Lin did a lot of cleanups." * tag 'pinctrl-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (66 commits) pinctrl: move subsystem mutex to pinctrl_dev struct pinctrl/pinconfig: fix misplaced goto pinctrl: s3c64xx: Fix build error caused by undefined chained_irq_enter pinctrl/pinconfig: add debug interface pinctrl: abx500: fix issue when no pdata pinctrl: pinctrl-single: add missing double quote pinctrl: sunxi: Rename wemac functions to emac pinctrl: exynos5440: add gpio interrupt support pinctrl: exynos5440: fix probe failure due to missing pin-list in config nodes pinctrl: ab8505: Staticize some symbols pinctrl: ab8540: Staticize some symbols pinctrl: ab9540: Staticize some symbols pinctrl: ab8500: Staticize some symbols pinctrl: abx500: Staticize some symbols pinctrl: Add pinctrl-s3c64xx driver pinctrl: samsung: Handle banks with two configuration registers pinctrl: samsung: Remove hardcoded register offsets pinctrl: samsung: Split pin bank description into two structures pinctrl: samsung: Include pinctrl-exynos driver data conditionally pinctrl: samsung: Protect bank registers with a spinlock ...

2013-04-26efivars: only check for duplicates on the registered listMatt Fleming
variable_is_present() accesses '__efivars' directly, but when called via gsmi_init() Michel reports observing the following crash, BUG: unable to handle kernel NULL pointer dereference at (null) IP: variable_is_present+0x55/0x170 Call Trace: register_efivars+0x106/0x370 gsmi_init+0x2ad/0x3da do_one_initcall+0x3f/0x170 The reason for the crash is that '__efivars' hasn't been initialised nor has it been registered with register_efivars() by the time the google EFI SMI driver runs. The gsmi code uses its own struct efivars, and therefore, a different variable list. Fix the above crash by passing the registered struct efivars to variable_is_present(), so that we traverse the correct list.

2013-04-26pinctrl: move subsystem mutex to pinctrl_dev structPatrice Chotard
This mutex avoids deadlock in case of use of multiple pin controllers. Before this modification, by using a global mutex, deadlock appeared when, for example, a call to pinctrl_pins_show() locked the pinctrl_mutex, called the ops->pin_dbg_show of a particular pin controller. If this pin controller needs I2C access to retrieve configuration information and I2C driver is using pinctrl to drive its pins, a call to pinctrl_select_state() try to lock again pinctrl_mutex which leads to a deadlock. Notice that the mutex grab from the two direction functions was moved into pinctrl_gpio_direction(). For several cases, we can't replace pinctrl_mutex by pctldev->mutex, because at this stage, pctldev is not accessible : - pinctrl_get()/pinctrl_put() - pinctrl_register_maps() So add respectively pinctrl_list_mutex and pinctrl_maps_mutex in order to protect pinctrl_list and pinctrl_maps list instead. Reintroduce pinctrldev_list_mutex in find_pinctrl_by_of_node(), pinctrl_find_and_add_gpio_range() pinctrl_request_gpio(), pinctrl_free_gpio(), pinctrl_gpio_direction(), pinctrl_devices_show(), pinctrl_register() and pinctrl_unregister() to protect pinctrldev_list. Changes v2->v3: - Fix a missing EXPORT_SYMBOL_GPL() for pinctrl_select_state(). Changes v1->v2: - pinctrl_select_state_locked() is removed, all lock mechanism is located inside pinctrl_select_state(). When parsing the state->setting list, take the per-pin-controller driver lock. (Patrice). - Introduce pinctrldev_list_mutex to protect pinctrldev_list in all functions which parse or modify pictrldev_list. (Patrice). - move find_pinctrl_by_of_node() from pinctrl/devicetree.c to pinctrl/core.c in order to protect pinctrldev_list. (Patrice). - Sink mutex:es into some functions and remove some _locked variants down to where the lists are actually accessed to make things simpler. (Linus) - Drop *all* mutexes completely from pinctrl_lookup_state() and pinctrl_select_state() - no relevant mutex was taken and it was unclear what this was protecting against.

2013-04-26TTY: fix atime/mtime regressionJiri Slaby
In commit b0de59b5733d ("TTY: do not update atime/mtime on read/write") we removed timestamps from tty inodes to fix a security issue and waited if something breaks. Well, 'w', the utility to find out logged users and their inactivity time broke. It shows that users are inactive since the time they logged in. To revert to the old behaviour while still preventing attackers to guess the password length, we update the timestamps in one-minute intervals by this patch.

2013-04-26s390/memory hotplug: prevent offline of active memory incrementsHeiko Carstens
In case a machine supports memory hotplug all active memory increments present at IPL time have been initialized with a "usecount" of 1. This is wrong if the memory increment size is larger than the memory section size of the memory hotplug code. If that is the case the usecount must be initialized with the number of memory sections that fit into one memory increment. Otherwise it is possible to put a memory increment into standby state even if there are still active sections. Afterwards addressing exceptions might happen which cause the kernel to panic. However even worse, if a memory increment was put into standby state and afterwards into active state again, it's contents would have been zeroed, leading to memory corruption. This was only an issue for machines that support standby memory and have at least 256GB memory. This is broken since commit fdb1bb15 "[S390] sclp/memory hotplug: fix initial usecount of increments".

2013-04-23pinctrl: s3c64xx: Fix build error caused by undefined chained_irq_enterTomasz Figa
Commit de88cbb7 moved definitions of chained_irq_enter and chained_irq_exit to a generic header, which must be now included instead of the legacy arch-specific one. This patch fixes build error caused by including the legacy header leading to undefined chained_irq_enter and chained_irq_exit symbols.

Make sure we don't execute the early microcode patching if family < 6, since it would touch MSRs which don't exist on those families, causing crashes. 2. The Xen partial emulation of HyperV can be dealt with more gracefully than just disabling the driver. 3. More EFI variable space magic. In particular, variables hidden from runtime code need to be taken into account too." * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, microcode: Verify the family before dispatching microcode patching x86, hyperv: Handle Xen emulation of Hyper-V more gracefully x86,efi: Implement efi_no_storage_paranoia parameter efi: Export efi_query_variable_store() for efivars.ko x86/Kconfig: Make EFI select UCS2_STRING efi: Distinguish between "remaining space" and actually used space efi: Pass boot services variable info to runtime code Move utf16 functions to kernel core and rename x86,efi: Check max_size only if it is non-zero. x86, efivars: firmware bug workarounds should be in platform code

2013-04-19net: ax88796: avoid 64 bit arithmeticArnd Bergmann
When building ax88796 on an ARM platform with 64-bit resource_size_t, we currently get drivers/net/ethernet/8390/ax88796.c:875: undefined reference to `__aeabi_uldivmod' because we do a division on the length of the MMIO resource. Since we know that this resource is very short, using an "unsigned long" instead of "resource_size_t" is entirely sufficient, and avoids this link-time error.
