Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* chcr: Support for Chelsio's Crypto HardwareHariprasad Shenai2016-08-195-0/+2519
The Chelsio's Crypto Hardware can perform the following operations: SHA1, SHA224, SHA256, SHA384 and SHA512, HMAC(SHA1), HMAC(SHA224), HMAC(SHA256), HMAC(SHA384), HAMC(SHA512), AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-XTS, AES-256-XTS This patch implements the driver for above mentioned features. This driver is an Upper Layer Driver which is attached to Chelsio's LLD (cxgb4) and uses the queue allocated by the LLD for sending the crypto requests to the Hardware and receiving the responses from it. The crypto operations can be performed by Chelsio's hardware from the userspace applications and/or from within the kernel space using the kernel's crypto API. The above mentioned crypto features have been tested using kernel's tests mentioned in testmgr.h. They also have been tested from user space using libkcapi and Openssl.
