In commit ee6aeff, a swatch warning was fixed by moving some code inside
an if block that is executed only when the pointer padapter is not NULL.
In fact, padapter can never be NULL and the corect fix should have been
the removal of the test of padapter.

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.

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.

bootmem
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).

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.

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.

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.
