Subject: [PATCH v3 0/5] crypto: hisilicon - Improve SEC performance

From: Longfang Liu <[email protected]>

Improve SEC throughput by allocating a workqueue for each device
instead of one workqueue for all SEC devices. What's more,
when IOMMU translation is turned on, the plat buffer (pbuffer)
will be reserved for small packets (<512Bytes) to
which small packets are copied. This can avoid DMA mapping on
user small packets and improve performance.

This series is based on:
git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git

Changes v2 -> v3:
- Updated some comments and commit messages from Jonathan Cameron.
- Removed CPU intensive workqueue flag WQ_CPU_INTENSIVE
- Some small misc fixes.

Changes v1 -> v2:
- Split pbuf patch into two patches.
- Move 'use_pbuf' from 'qp_ctx' to TFM request.
- Misc fixes on coding style.

Longfang Liu (3):
crypto: hisilicon/sec2 - Add iommu status check
crypto: hisilicon/sec2 - Update IV and MAC operation
crypto: hisilicon/sec2 - Add pbuffer mode for SEC driver

Shukun Tan (1):
crypto: hisilicon - Use one workqueue per qm instead of per qp

Ye Kai (1):
crypto: hisilicon/sec2 - Add workqueue for SEC driver.
