2013-10-30Merge remote-tracking branch 'scott/next' into nextBenjamin Herrenschmidt
Highlights include corenet board file consolidation, the ability to run userspaces with lwsync on e500v1/v2, some cleanup patches that other KVM patches will build on, support for stripped-down e6500 emulation targets, and some fixes of minor longstanding issues.
2013-10-29mdio_bus: convert bus code to use dev_groupsGreg Kroah-Hartman
The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the MDIO bus code to use the correct field. Cc: David S.

2013-10-29misc/at24: avoid infinite loop on write()Vladimir Zapolskiy

2013-10-29misc: atmel_pwm: add deferred-probing supportJohan Hovold
Two drivers (atmel-pwm-bl and leds-atmel-pwm) currently depend on the atmel_pwm driver to have bound to any pwm-device before their devices are probed. Support deferred probing of such devices by making sure to return -EPROBE_DEFER from pwm_channel_alloc when no pwm-device has yet been bound.

2013-10-29lkdtm: add tests for additional page permissionsKees Cook
Testing execution and access of userspace from the kernel is needed for validating things like Intel's SMEP and SMAP protections.

2013-10-29lkdtm: adjust recursion size to avoid warningsKees Cook
When CONFIG_FRAME_WARN is set low (e.g. some ARM builds), the hard-coded stack buffer size used for kernel stack over run testing triggers build warnings. Instead, avoid the warning by recalcuating the buffer size and recursion count needed to trigger the test. Also uses the recursion counter indirectly to avoid changing the parameter during the test.

2013-10-29device: Make dev_WARN/dev_WARN_ONCE print device as well as driver nameBjorn Helgaas
dev_WARN() and dev_WARN_ONCE() are annoying because (1) they include only the driver name, not the device name, and (2) they print a spurious newline in the middle. This results in messages like this that are less useful than they should be: [ 40.094995] Device pcieport disabling already-disabled device This patch makes them work more like dev_printk().

2013-10-29sysfs: separate out dup filename warning into a separate functionTejun Heo
Separate out sysfs_warn_dup() out of sysfs_add_one(). This will help separating out the core sysfs functionalities into kernfs so that it can be used by non-sysfs users too.

2013-10-29sysfs: honor bin_attr.attr.ignore_lockdepTejun Heo
ignore_lockdep is currently honored only for regular files. There's no reason to ignore it for bin files. Update sysfs_ignore_lockdep() so that bin_attr.attr.ignore_lockdep works too. While this doesn't have any in-kernel user, this unifies the behaviors between regular and bin files and will help later changes.

2013-10-29sysfs: merge sysfs_elem_bin_attr into sysfs_elem_attrTejun Heo
3124eb1679 ("sysfs: merge regular and bin file handling") folded bin file handling into regular file handling. Among other things, bin file now shares the same open path including sysfs_open_dirent association using sysfs_dirent->s_attr.open. This is buggy because ->s_bin_attr lives in the same union and doesn't have the field. This bug doesn't trigger because sysfs_elem_bin_attr doesn't have an active field at the conflicting position. It does have a field "buffers" but it isn't used anymore. This patch collapses sysfs_elem_bin_attr into sysfs_elem_attr so that the bin_attr is accessed through ->s_attr.bin_attr which lives with ->s_attr.attr in an anonymous union. The code paths already assume bin_attr contains attr as the first element, so this doesn't add any more assumptions while making it explicit that the two types are handled together.

Always register the R4K clocksource when CONFIG_CSRC_R4K is selected, regardless of selected support for other clocksources.
