This patch increases the performance of AES x86-64 implementation. The
average increment is more than 6.3% and the max increment is
more than 10.2% on Intel CORE 2 CPU. The performance increment is
gained via the following methods:
- Two additional temporary registers are used to hold the subset of
the state, so that the dependency between instructions is reduced.
- The expanded key is loaded via 2 64bit load instead of 4 32-bit load.
This patch is based on 2.6.25-rc8-mm1.
The file attached is the test data via: modprobe tcrypt mode=200
- dmesg_1_core-stockn: stock kernel data
- dmesg_1_core-op4n: patched kernel data
- percent.txt: (time_patched - time_stock) / time_stock * 100
