This patch moves pin SD3_DAT5/4 (CD/WP) from pinctrl_hog to pinctrl_usdhc3. It also explicitly sets the pad SD3_DAT5 to 0x1b0b0, which is also the value that it has before this patch if using mainline u-boot.

This makes the structure of Sabre Lite board files the same as Sabre SD board files so that they are easier to compare. By this, I mean that the majority of the file imx6q-sabrelite.dts is moved to imx6qdl-sabrelite.dtsi so that both imx6q-sabrelite.dts and imx6dl-sabrelite.dts can include it. Now Sabre Lite has support for Dual Lite/Solo processors.

We must specify the value of audmux pinctrl if we want to use pinctrl_pm(). Thus change bypass value 0x80000000 to what we exactly need. This patch also seperately unset PUE bit for TXD so that IOMUX won't pull up/down the pin after turning into tristate. When we use SSI normal mode to playback monaural audio via I2S signal, there'd be a pulled curve occur to its signal at the second slot if setting PUE bit for TXD. And it will make the second channel to play a constant noise. So by keeping the signal level in the second slot, we can get a constant high level signal (-1) or a low level one (0).

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that boards that share the same pinctrl setting do not have to define it time and time again in <board>.dts. However, along with the devices and use cases being added continuously, the pinctrl setting nodes under iomuxc becomes more than expected. This bloats device tree blob for particular board unnecessarily since only a small subset of those pinctrl setting nodes will be used by the board. It impacts not only the DTB file size but also the run-time device tree lookup efficiency. The patch moves all the pinctrl data into individual boards as needed. With the changes, the pinctrl setting nodes becomes local to particular board, and it makes no sense to continue numbering the setting for given peripheral. Thus, all the pinctrl phandler name gets updated to have only peripheral name in there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Pull parisc updates from Helge Deller: "The three major changes in this patchset is a implementation for flexible userspace memory maps, cache-flushing fixes (again), and a long-discussed ABI change to make EWOULDBLOCK the same value as EAGAIN. parisc has been the only platform where we had EWOULDBLOCK != EAGAIN to keep HP-UX compatibility. Since we will probably never implement full HP-UX support, we prefer to drop this compatibility to make it easier for us with Linux userspace programs which mostly never checked for both values. We don't expect major fall-outs because of this change, and if we face some, we will simply rebuild the necessary applications in the debian archives" * 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: add flexible mmap memory layout support parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc parisc: convert uapi/asm/stat.h to use native types only parisc: wire up sched_setattr and sched_getattr parisc: fix cache-flushing parisc/sti_console: prefer Linux fonts over built-in ROM fonts

HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).

Add support for the flexible mmap memory layout (as described in http://lwn.net/Articles/91829). This is especially very interesting on parisc since we currently only support 32bit userspace (even with a 64bit Linux kernel). Signed-off-by: Helge Deller <deller@gmx.de>

The built-in ROM fonts lack many necessary ASCII characters, which is why it makes sens to prefer the Linux fonts instead if they are available. This makes consoles on STI graphics cards which are not supported by the stifb driver (e.g. Visualize FXe) looks much nicer.
