sparc64: Set CRYPTO_TFM_REQ_MAY_SLEEP consistently in CAMELLIA code.

2013-01-11T17:18:51+00:00

[ Upstream commit 62ba63dc892cf836ecb9ce4fdb7644d45c95070b ]

We use the FPU and therefore cannot sleep during the crypto
loops.

Things works better when you increment the source buffer pointer
properly.

sparc64: Fix AES ctr mode block size.

2013-01-11T17:18:51+00:00

[ Upstream commit a8d97cef2168ffe5af1aeed6bf6cdc3ce53f3d0b ]

Like the generic versions, we need to support a block size
of '1' for CTR mode AES.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

sparc64: Fix unrolled AES 256-bit key loops.

2013-01-11T17:18:50+00:00

[ Upstream commit 9f28ffc03e93343ac04874fda9edb7affea45165 ]

The basic scheme of the block mode assembler is that we start by
enabling the FPU, loading the key into the floating point registers,
then iterate calling the encrypt/decrypt routine for each block.

For the 256-bit key cases, we run short on registers in the unrolled
loops.

So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that
get clobbered.

The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this.

So if we have a mix of multi-block and single-block calls, the
single-block unrolled 256-bit encrypt/decrypt can run with some
of the key registers clobbered.

Handle this by always explicitly loading those registers before using
the non-unrolled 256-bit macro.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

sparc: huge_ptep_set_* functions need to call set_huge_pte_at()

2013-01-11T17:18:50+00:00

[ Upstream commit 6cb9c3697585c47977c42c5cc1b9fc49247ac530 ]

Modifying the huge pte's requires that all the underlying pte's be
modified.

sparc: Fix piggyback with newer binutils.

2012-12-03T19:24:25+00:00

Newer versions of binutils mark '_end' as 'B' instead of 'A' for
whatever reason.

To be honest, the piggyback code doesn't actually care what kind
of symbol _start and _end are, it just wants to find them and
record the address.

So remove the type from the match strings.
