arch/avr32/kernel/cpu.c needs THIS_MODULE, so it must include
linux/module.h.

Since size_t is defined as unsigned long, ssize_t ought to be long
and not int. It could have been the other way around, but gcc defines
size_t as unsigned long, so this is correct.
This fixes a couple of printk format warnings.

The PIOE device was left out before because it muxes SDRAM pins (and
is therefore a bit dangerous to mess with) and because no existing
drivers had any use for it.
It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.

at32_reserve_pin() can be used for reserving portmux pins without
altering their configuration. Useful for e.g. SDRAM pins where we
really don't want to change the bootloader-provided configuration.

Fix bug in dma_map_single(..., DMA_FROM_DEVICE) caused by incorrect
invalidation of shared cachelines at the beginning and/or end of
the specified buffer. Those shared cachelines need to be flushed,
since they may hold valid data (which must not be discarded).

Bugfixes for external irq handler set_irq_type():
- If set_irq_type() can't set the type, don't change anything!
- It's not OK to change the flow handler as part of set_irq_type(),
among other issues that violates spinlock rules. Instead, we can
call the relevant handler when we demux the external interrupts.
- The external irq demux has no need to grab the spinlock. And in
fact grabbing it that way was wrong, since that code might be
pre-empted by an irq at a different priority level, and that code
might then have tried to grab that spinlock...

Using blkcipher/hash crypto operations in hard IRQ context can lead
to random memory corruption due to the reuse of kmap_atomic slots.
Since crypto operations were never meant to be used in hard IRQ
contexts, this patch checks for such usage and returns an error
before kmap_atomic is performed.

GCC (correctly) says:
net/socket.c: In function ‘sys_sendto’:
net/socket.c:1510: warning: ‘err’ may be used uninitialized in this function
net/socket.c: In function ‘sys_recvfrom’:
net/socket.c:1571: warning: ‘err’ may be used uninitialized in this function
sock_from_file() either returns filp->private_data or it
sets *err and returns NULL.
Callers return "err" on NULL, but filp->private_data could
be NULL.
Some minor rearrangements of error handling in sys_sendto
and sys_recvfrom solves the issue.

I believe dead code from sock_from_file() can be cleaned up.
All sockets are now built using sock_attach_fd(), that puts the 'sock' pointer
into file->private_data and &socket_file_ops into file->f_op
I could not find a place where file->private_data could be set to NULL,
keeping opened the file.
So to get 'sock' from a 'file' pointer, either :
- This is a socket file (f_op == &socket_file_ops), and we can directly get
'sock' from private_data.
- This is not a socket, we return -ENOTSOCK and dont even try to find a socket
via dentry/inode :)

ehash table layout is currently this one :
First half of this table is used by sockets not in TIME_WAIT state
Second half of it is used by sockets in TIME_WAIT state.
This is non optimal because of for a given hash or socket, the two chain heads
are located in separate cache lines.
Moreover the locks of the second half are never used.
If instead of this halving, we use two list heads in inet_ehash_bucket instead
of only one, we probably can avoid one cache miss, and reduce ram usage,
particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK,
CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep
together related chains to speedup lookups and socket state change.
In this patch I did not try to align struct inet_ehash_bucket, but a future
patch could try to make this structure have a convenient size (a power of two
or a multiple of L1_CACHE_SIZE).
I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so
maybe we dont need to scratch our heads to align the bucket...
Note : In case struct inet_ehash_bucket is not a power of two, we could
probably change alloc_large_system_hash() (in case it use __get_free_pages())
to free the unused space. It currently allocates a big zone, but the last
quarter of it could be freed. Again, this should be a temporary 'problem'.
Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.
