[PATCH 5/5] crypto: cast5/avx - avoid using temporary stack buffers

Introduce new assembler functions to avoid use temporary stack buffers in glue code. This also allows use of vector instructions for xoring output in CTR and CBC modes and construction of IVs for CTR mode. ECB mode sees ~0.5% decrease in speed because added one extra function call. CBC mode decryp

[PATCH 1/5] crypto: x86/glue_helper - use le128 instead of u128 for CTR mode

'u128' currently used for CTR mode is on little-endian 'long long' swapped and would require extra swap operations by SSE/AVX code. Use of le128 instead of u128 allows IV calculations to be done with vector registers easier. Signed-off-by: Jussi Kivilinna --- arch/x86/crypto/camellia_glue.c

[PATCH 0/5] Avoid stack buffers in glue code of AVX implementations

Patches modify AVX implementations so that they avoid using extra stack memory. Stack is not needed since implementation store blocks in registers. --- Jussi Kivilinna (5): crypto: x86/glue_helper - use le128 instead of u128 for CTR mode crypto: cast6/avx - avoid using temporary stack

[PATCH] crypto: cryptd - disable interrupts in cryptd_queue_worker to prevent data corruption

cryptd_queue_worker attempts to prevent simultaneous accesses to crypto workqueue by cryptd_enqueue_request using preempt_disable/preempt_enable. However cryptd_enqueue_request might be called from interrupt context, so add local_irq_save/local_irq_restore to prevent data corruption and panics. Bu
