Subject[PATCH 0/8] NX crypto driver reestructure

This set of patches deals with the reescruture of NX driver replacing the
use of spinlocks, that assure crypto context concurrency, by a copy of crypto
ctx to another region of memory in order to be used by the current algorithm.
As this region of memory tends to be used constantly also was added a kmemcache
chunk avoiding the cost of constant allocations.


Leonidas Da Silva Barbosa (8):
Adding nx_copy_ctx and kmemcache to handle with crypto context
Replacing spinlocks by nx_copy_ctx on NX-AES-CBC
Replacing spinlocks by nx_copy_ctx on NX-AES-CCM
Replacing spinlocks by nx_copy_ctx on NX-AES-CTR
Replacing spinlocks by nx_copy_ctx on NX-AES-ECB
Replacing spinlocks by nx_copy_ctx on NX-AES-GCM
Replacing spinlocks by nx_copy_ctx on NX-AES-XCBC
Replacing spinlocks by nx_copy_ctx on NX-SHA256 and NX-SHA512
