This patch adds the kernel side of the PPS support currently named "LinuxPPS". PPS means "pulse per second" and a PPS source is just a device which provides a high precision signal each second so that an application can use it to adjust system clock time. Common use is the combination of the NTPD as userland program with a GPS receiver as PPS source to obtain a wallclock-time with sub-millisecond synchronisation to UTC. To obtain this goal the userland programs shoud use the PPS API specification (RFC 2783 - Pulse-Per-Second API for UNIX-like Operating Systems, Version 1.0) which in part is implemented by this patch. It provides a set of chars devices, one per PPS source, which can be used to get the time signal. The RFC's functions can be implemented by accessing to these char devices.

On embedded devices, sleep mode conditions can be tricky to handle, Especially when processors tend to pull-down the w1 bus during sleep. Bus slaves (such as the ds2760) may interpret this as a reason for power-down conditions and entirely switch off the device. This patch adds a callback function pointer to let users switch on and off the external pull-up resistor. This lets the outside world know whether the processor is currently actively driving the bus or not. When this callback is not provided, the code behaviour won't change.

We unified x86 and IA64's handling of multiple dma mapping operations (struct dma_map_ops in linux/dma-mapping.h) so we can remove duplication in their arch/include/asm/dma-mapping.h. This patchset adds include/asm-generic/dma-mapping-common.h that provides some generic dma mapping function definitions for the users of struct dma_map_ops. This enables us to remove about 100 lines. This also enables us to easily add CONFIG_DMA_API_DEBUG support, which only x86 supports for now. The 4th patch adds CONFIG_DMA_API_DEBUG support to IA64 by adding only 8 lines. This patch: This header file provides some mapping function definitions that the users of struct dma_map_ops can use.

Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

find_task_by_pid_type_ns is only used to implement find_task_by_vpid and find_task_by_pid_ns, but both of them pass PIDTYPE_PID as first argument. So just fold find_task_by_pid_type_ns into find_task_by_pid_ns and use find_task_by_pid_ns to implement find_task_by_vpid. While we're at it also remove the exports for find_task_by_pid_ns and find_task_by_vpid - we don't have any modular callers left as the only modular caller of he old pre pid namespace find_task_by_pid (gfs2) was switched to pid_task which operates on a struct pid pointer instead of a pid_t. Given the confusion about pid_t values vs namespace that's generally the better option anyway and I think we're better of restricting modules to do it that way.

This patch fixes mis-accounting of swap usage in memcg. In the current implementation, memcg's swap account is uncharged only when swap is completely freed. But there are several cases where swap cannot be freed cleanly. For handling that, this patch changes that memcg uncharges swap account when swap has no references other than cache. By this, memcg's swap entry accounting can be fully synchronous with the application's behavior. This patch also changes memcg's hooks for swap-out.

Add file RSS tracking per memory cgroup We currently don't track file RSS, the RSS we report is actually anon RSS. All the file mapped pages, come in through the page cache and get accounted there. This patch adds support for accounting file RSS pages. It should 1. Help improve the metrics reported by the memory resource controller 2. Will form the basis for a future shared memory accounting heuristic that has been proposed by Kamezawa. Unfortunately, we cannot rename the existing "rss" keyword used in memory.stat to "anon_rss".

Several code paths in reiserfs have a construct like: if (is_direntry_le_ih(ih = B_N_PITEM_HEAD(src, item_num))) ... which, in addition to being ugly, end up causing compiler warnings with gcc 4.4.0. Previous compilers didn't issue a warning. fs/reiserfs/do_balan.c:1273: warning: operation on `aux_ih' may be undefined fs/reiserfs/lbalance.c:393: warning: operation on `ih' may be undefined fs/reiserfs/lbalance.c:421: warning: operation on `ih' may be undefined fs/reiserfs/lbalance.c:777: warning: operation on `ih' may be undefined I believe this is due to the ih being passed to macros which evaluate the argument more than once. This is old code and we haven't seen any problems with it, but this patch eliminates the warnings. It converts the multiple evaluation macros to static inlines and does a preassignment for the cases that were causing the warnings because that code is just ugly.

This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions).

The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

Add accelerated bitblt functions to s1d13xxx based video chipsets, more specificly functions copyarea and fillrect. It has only been tested and activated for 13506 chipsets but is expected to work for the majority of s1d13xxx based chips. This patch also cleans up the driver with respect of whitespaces and other formatting issues. We update the current status comments.

With KMS we have ran into an issue where we really want the KMS fb driver to be the one running the console, so panics etc can be shown by switching out of X etc. However with vesafb/efifb built-in, we end up with those on fb0 and the KMS fb driver on fb1, driving the same piece of hw, so this adds an fb info flag to denote a firmware fbdev, and adds a new aperture base/size range which can be compared when the hw drivers are installed to see if there is a conflict with a firmware driver, and if there is the firmware driver is unregistered and the hw driver takes over. It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.
