2013-10-29printk: pr_debug_ratelimited: check state first to reduce "callbacks ↵Joe Perches
suppressed" messages pr_debug_ratelimited should be coded similarly to dev_dbg_ratelimited to reduce the "callbacks suppressed" messages. Add #include <linux/dynamic_debug.h> to printk.h. Unfortunately, this new #include must be after the prototype/declaration of function printk. It may be better to split out these _ratelimited declarations into a separate file one day. Any use of these pr_<foo>_ratelimited functions must also have another specific #include <ratelimited.h>. Most users have this done indirectly via #include <linux/kernel.h> printk.h may not #include <linux/ratelimit.h> as it causes circular dependencies and compilation failures.

2013-10-29serial: omap: Add support for optional wake-upTony Lindgren
With the recent pinctrl-single changes, omaps can treat wake-up events from deeper idle states as interrupts. There's a separate "io chain" controller on most omaps that stays enabled when the device hits off-idle and the regular interrupt controller is powered off. Let's add support for the optional second interrupt for wake-up events. And then serial-omap can manage the wake-up interrupt from it's runtime PM calls to avoid spurious interrupts during runtime. Note that the wake interrupt is board specific as it uses the UART RX pin, and for omap3, there are six pin options for UART3 RX pin. Also Note that the legacy platform based booting handles the wake-ups in the legacy mux driver and does not need to pass the wake-up interrupt to the driver. And finally, to pass the wake-up interrupt in the dts file, either interrupt-map or the pending interrupts-extended property needs to be passed. It's probably best to use interrupts-extended when it's available.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to vxlan, net, ixgbe, ixgbevf, and i40e. Joseph provides a single patch against vxlan which removes the burden from the NIC drivers to check if the vxlan driver is enabled in the kernel and also makes available the vxlan headrooms to the drivers. Jacob provides majority of the patches, with patches against net, ixgbe and ixgbevf. His net patch adds might_sleep() call to napi_disable so that every use of napi_disable during atomic context will be visible. Then Jacob provides a patch to fix qv_lock_napi call in ixgbe_napi_disable_all. The other ixgbe patches cleanup ixgbe_check_minimum_link function to correctly show that there are some minor loss of encoding, even though we don't calculate it and remove unnecessary duplication of PCIe bandwidth display. Lastly, Jacob provides 4 patches against ixgbevf to add ixgbevf_rx_skb in line with how ixgbe handles the variations on how packets can be received, adds support in order to track how many packets were cleaned during busy poll as part of the extended statistics. Wei Yongjun provides a fix for i40e to return -ENOMEN in the memory allocation error handling case instead of returning 0, as done elsewhere in this function. ==================== Signed-off-by: David S.

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.
