Herbert Xu a8d7ac2797 crypto: padlock-sha - Add import/export support
As the padlock driver for SHA uses a software fallback to perform
partial hashing, it must implement custom import/export functions.
Otherwise hmac which depends on import/export for prehashing will
not work with padlock-sha.

Márton Németh 6c3f975a4c crypto: Make Open Firmware device id constant
From: Márton Németh <nm127@freemail.hu>

The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make the initialization data also constant.

The fallback code in cipher mode touch the union fallback.blk instead
of fallback.cip. This is wrong because we use the cipher and not the
blockcipher. This did not show any side effects yet because both types /

Tejun Heo 390dfd95c5 percpu: make misc percpu symbols unique
This patch updates misc percpu related symbols such that percpu
symbols are unique and don't clash with local symbols.  This serves
two purposes of decreasing the possibility of global percpu symbol
collision and allowing dropping per_cpu__ prefix from percpu symbols.

* drivers/crypto/padlock-aes.c: s/last_cword/paes_last_cword/

* drivers/lguest/x86/core.c: s/last_cpu/lg_last_cpu/

* drivers/s390/net/netiucv.c: rename the variable used in a macro to
  avoid clashing with percpu symbol

* arch/mn10300/kernel/kprobes.c: replace current_ prefix with cur_ for
  static variables.  Please note that percpu symbol current_kprobe
  can't be changed as it's used by generic code.

Partly based on Rusty Russell's "alloc_percpu: rename percpu vars
which cause name clashes" patch.

Herbert Xu 4c6ab3ee4c crypto: padlock-sha - Fix stack alignment
The PadLock hardware requires the output buffer for SHA to be
128-bit aligned.  We currentply place the buffer on the stack,
and ask gcc to align it to 128 bits.  That doesn't work on i386
because the kernel stack is only aligned to 32 bits.  This patch
changes the code to align the buffer by hand so that the hardware
doesn't fault on unaligned buffers.

Herbert Xu faae890883 crypto: padlock - Fix compile error on i386
The previous change to allow hashing from states other than the
initial broke compilation on i386 because the inline assembly
tried to squeeze a u64 into a 32-bit register.  As we've already
checked for 32-bit overflows we can simply truncate it to u32,
or unsigned long so that we don't truncate at all on x86-64.

This patch changes crypto4xx to use the new style ahash type.
In particular, we now use ahash_alg to define ahash algorithms

This is achieved by introducing a union that encapsulates the
new type and the existing crypto_alg structure.  They're told
apart through a u32 field containing the type value.

Herbert Xu bbbee4679a crypto: padlock - Switch sha to shash
This patch converts the padlock-sha implementation to shash.
In doing so the existing mechanism of storing the data until
final is no longer viable as we do not have a way of allocating
data in crypto_shash_init and then reliably freeing it.

This is just as well because a better way of handling the problem
is to hash everything but the last chunk using normal sha code
and then provide the intermediate result to the padlock device.

This is good enough because the primary application of padlock-sha
is IPsec and there the data is laid out in the form of an hmac
header followed by the rest of the packet.  In essence we can
provide all the data to the padlock as the hmac header only needs
to be hashed once.

Herbert Xu a760a6656e crypto: api - Fix module load deadlock with fallback algorithms
With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first.  The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.

As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.

As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest.  Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.

Lee Nipper ca38a814c6 crypto: talitos - Ack done interrupt in isr instead of tasklet
Previous commit for interrupt mitigation moved the done interrupt
acknowlegement from the isr to the talitos_done tasklet.
This patch moves the done interrupt acknowledgement back
into the isr so that done interrupts will always be acknowledged.
This covers the case for acknowledging interrupts for channel done processing
that has actually already been completed by the tasklet prior to fielding
a pending interrupt.
