crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementation Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations in parallel to improve performance on out-of-order CPUs). Glue code is based on one from AES-NI implementation, so requests from irq context are redirected to cryptd. v2: - add missing include of linux/module.h (appearently crypto.h used to include module.h, which changed for 3.2 by commit 7c926402a7e8c9b279968fd94efec8700ba3859e) Patch has been tested with tcrypt and automated filesystem tests.

crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementation Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations in parallel to improve performance on out-of-order CPUs). Glue code is based on one from AES-NI implementation, so requests from irq context are redirected to cryptd. v2: - add missing include of linux/module.h (appearently crypto.h used to include module.h, which changed for 3.2 by commit 7c926402a7e8c9b279968fd94efec8700ba3859e) Patch has been tested with tcrypt and automated filesystem tests.
