Subject: [PATCH 0/3] crypto: x86/aesni - Improve XTS data type

The field within the struct aesni_xts_ctx is currently defined as a
byte array, sized to match the struct crypto_aes_ctx. However, it
actually represents the struct data type.

To accurately redefine the data type, some adjustments have to be made
to the address alignment code. It involved refactoring the common
alignment code initially, followed by updating the structure's
definition. Finally, the XTS alignment is now performed early in the
process, rather than at every access point.

This change was suggested during Eric's review of another series
intended to enable an alternative AES implementation [1][2]. I viewed
it as an enhancement to the mainline, independent of the series.

I have divided these changes into incremental pieces, making them
considerably more reviewable and maintainable.

The series is based on the cryptodev's master branch:

    git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git master

Thanks,
Chang
