2017-04-27dm ioctl: prevent stack leak in dm ioctl callAdrian Salido
When calling a dm ioctl that doesn't process any data (IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct dm_ioctl are left initialized. Current code is incorrectly extending the size of data copied back to user, causing the contents of kernel stack to be leaked to user. Fix by only copying contents before data and allow the functions processing the ioctl to override.

2017-04-27statx: correct error handling of NULL pathnameMichael Kerrisk (man-pages)
The change in commit 1e2f82d1e9d1 ("statx: Kill fd-with-NULL-path support in favour of AT_EMPTY_PATH") to error on a NULL pathname to statx() is inconsistent. It results in the error EINVAL for a NULL pathname. Other system calls with similar APIs (fchownat(), fstatat(), linkat()), return EFAULT. The solution is simply to remove the EINVAL check. As I already pointed out in [1], user_path_at*() and filename_lookup() will handle the NULL pathname as per the other APIs, to correctly produce the error EFAULT.

2017-04-27rhashtable: Cap total number of entries to 2^31Herbert Xu
When max_size is not set or if it set to a sufficiently large value, the nelems counter can overflow. This would cause havoc with the automatic shrinking as it would then attempt to fit a huge number of entries into a tiny hash table. This patch fixes this by adding max_elems to struct rhashtable to cap the number of elements. This is set to 2^31 as nelems is not a precise count. This is sufficiently smaller than UINT_MAX that it should be safe. When max_size is set max_elems will be lowered to at most twice max_size as is the status quo.

So the CPCAP interrupt is clearly a level interrupt and not an edge interrupt.

MFD support for DA9061 is provided as part of the DA9062 device driver. The registers header file adds two new chip variant IDs defined in DA9061 and DA9062 hardware. The core header file adds new software enumerations for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration for distinguishing between DA9061/62 devices in software. The core source code adds a new .compatible of_device_id entry. This is extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The .data entry now holds a reference to the enumerated device type. A new regmap_irq_chip model is added for DA9061 and this supports the new list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the new sub system components for DA9061. Support is added for a new DA9061 regmap_config which lists the correct readable, writable and volatile ranges for this chip. The probe function uses the device tree compatible string to switch on the da9062_compatible_types and configure the correct mfd cells, irq chip and regmap config.
