Add the ADC driver for Atmel's AT91SAM9G20-EK, AT91SAM9M10G45-EK and AT91SAM9X5 family boards. It has support for both software and hardware triggers. Signed-off-by:

The AT91 SoCs often embeds an ADC. This patch adds the needed platform data to specify the informations required by the driver to work properly. For now, we only need the reference voltage and which channels are available on the board. Signed-off-by:

RAMster does many zcache-like things. In order to avoid major merge conflicts at 3.4, ramster used lzo1x directly for compression and retained a local copy of xvmalloc, while zcache moved to the new zsmalloc allocator and the crypto API. This patch moves ramster forward to use zsmalloc and crypto. Signed-off-by:

Currently the sysfs device attributes are created by the comedi core after each comedi device is created. This can lead to a race condition where userspace gets an add event before the files are created. Register the device attributes with the comedi class so that the driver core handles creating them and we avoid the race. Signed-off-by:

A corresponding function to persistent_ram_new(). Signed-off-by:

This includes devices' memory (e.g. framebuffers or memory mapped EEPROMs on a local bus), as well as the normal RAM that we don't use for the main memory. For the normal (but unused) ram we could use kmaps, but this assumes highmem support, so we don't bother and just use the memory via ioremap. As a side effect, the following hack is possible: when used together with pstore_ram (new ramoops) module, we can limit the normal RAM region with mem= and then point ramoops to use the rest of the memory, e.g. mem=128M ramoops.mem_address=0x8000000 Sure, we could just reserve the region with memblock_reserve() early in the arch/ code, and then register a pstore_ram platform device pointing to the reserved region. It's still a viable option if platform wants to do so. Also, we might want to use IO accessors in case of a real device, but for now we don't bother (the old ramoops wasn't using it either, so at least we don't make things worse). Signed-off-by:

Factor out vmap logic out of persistent_ram_buffer_map(), this will make the code a bit more understandable when we'll add support for non-bootmem memory. Signed-off-by:

The routine just creates a persistent ram zone at a specified address. For persistent_ram_init_ringbuffer() we'd need to add a 'struct persistent_ram' to the global list, and associate it with a device. We don't need all this complexity in pstore_ram, so we introduce the simple function. Signed-off-by:

Factor post init logic out of __persistent_ram_init(), we'll need it for the new persistent_ram_new() routine. Signed-off-by:

This is a longstanding bug, almost unnoticeable when calling persistent_ram_write() for small buffers. But when called for large data buffers, the write routine behaves incorrectly, as the size may never update: instead of clamping the size to the maximum buffer size, buffer_size_add_clamp() returns an error (which is never checked by the write routine, btw). To fix this, we now use buffer_size_add() that actually clamps the size to the max value. Also remove buffer_size_add_clamp(), it is no longer needed. Signed-off-by:

This changes the log initialization to be dynamic, but still at boot time. These changes are a predecessor to implementing runtime allocation and freeing of logs, to make the Android logger less hard-coded. Change from a fixed set of static log structures, to allocation at init time into a list. Return proper error numbers on log allocation failure.

This driver had headers like big_endian.h, little_endian.h, swab.h and yet we can throw them all in the trash can and the thing still builds on x86-64 and ppc, just by deleting the references to the deleted files.
