commit d95abbbb291bf5bce078148f53603ce9c0aa1d44 upstream. Testing the arm chromebook config against the upstream kernel produces a linker error for the zsmalloc module from staging. The symbol flush_tlb_kernel_range is not available there. Fix this by removing the reimplementation of unmap_kernel_range in the zsmalloc module and using the function directly. The unmap_kernel_range function is not usable by modules, so also disallow building the driver as a module for now.

2013-04-30dpa_offload: Add DPA IPsec componentAndrei Varvara
The DPA IPSec component exports a set of functions used to: - initialize the DPA IPSec module internal data structures - create and configure full inbound IPSec hardware accelerated paths - create and configure full outbound IPSec hardware accelerated paths - replace expired SAs (after rekeying) without packet loss During the initialization phase the DPA IPSec implementation performs a series of actions meant to remove the need to perform memory allocations and hardware/software object initializations during the runtime phases. INBOUND PATH: _____________ ______________ _______________________________ __________ || SA lookup ||--> || Decryption || --> || Inbound Policy Verification || --> || App Rx || ||___________|| ||____________|| ||_____________________________|| ||________|| The inbound processing of an encrypted packet begins by determining the SA that will be used for decryption and authentication. In accordance to the RFC the packets are classified based on a 3-tuple that uniquely identifies the SA. This 3-tuple is formed from: - the destination IP address in the IP header of the encrypted packet - the value of the IP protocol field in the IP header of the encrypted packet - the value in the SPI field in the ESP header A special case is that were the encrypted packets are encapsulated in an UDP header in order to support NAT traversal. In this case the classification key should contain the following fields: - the destination IP address in the IP header of the encrypted packet - the IP protocol field in the IP header of the encrypted packet - the SPI field in the ESP header - the source UDP port in the UDP header - the destination UDP port in the UDP header This lookup is offloaded to FMAN by means of classifier API and FMAN API. When an encrypted packet matches an offloaded key, it is directed by the hardware into the decryption process by enquing the packet to a SEC frame queue (FQ). A shared descriptor (representing the decryption SA) is set on this FQ and the SEC will begin the decryption process and then place the clear text packet to a FQ that is input for an offline port (OH). Processing continues with inbound policy verification done on OH using the FMAN hardware. After this step the packet is enqueued to a FQ created by the application which benefits of IPSec security OUTBOUND PATH: __________ _________________ ______________ __________________ || App Tx || --> || Policy Lookup || --> || Encryption || --> || Error Checking || ||________|| ||_______________|| ||____________|| ||________________|| The primary function of the policy lookup block is to classify frames and determine the correct SA on which they should be processed. The DPA IPSec can be configured to build a policy key using any subset of the following fields: - masked source IP address - masked destination IP address - optionally masked IP protocol field value - masked source port value / ICMP type field value - masked destination port value / ICMP code field value IP fragmentation can be configured per policy and is performed, if required, on the packets before being sent to the Encryption Block. A fragmentation header manipulation identifier has to be passed when offloading the policy. If a clear text packet hits an offloaded policy the packet will be directed by FMAN hardware into the proper FQ for SEC processing. After the SEC has completed all the required operations, a new frame is created containing the ESP encapsulated packet. This frame will be sent to the next block for further processing i.e input to offline port where error checking is done prior to forwarding the packet to an application desired FQ based on the SA that processed that packet.

2013-04-30dpa_offload: Add packet classification componentMarian Chereji
The packet classification offloading driver implements its functionalities using the NetCommSw FMan driver. It exposes an easy-to-use API which can be called either from kernel space or from user space (through the classification offloading driver wrapper). It is able to create or import (from FMD resources) 3 types of tables - exact match table, indexed table and HASH table. Imported tables can be either empty or prefilled. It offers an API to insert, remove, or modify entries. It allows the users to classify and - enqueue - multicast - discard - re-classify or - return-to-KeyGen network packets. It is able to create or import (from FMD resources) header manipulation operations and attach them to table entries. It allows runtime modification of existing (created or imported) header manipulation operations. It offers an API to create or import (from FMD resources) multicast groups. It allows the user to add or remove members to existing multicast groups.

2013-04-23fsl_qbman: Enable preemption in bman_create_affine_portal()Priyanka Jain
bman_create_affine_portal() calls bman_create_portal() which in turn calls request_irq() to register portal_isr. In case of PREEMPT_RT enabled, request_irq() is converted into request_threaded_irq() as portal_isr is threaded IRQ handler. But this request_threaded_irq() can sleep, so it is mandatory to call request_threaded_irq() only from context that can sleep. bman_create_affine_portal() is called from context that is already affine to CPU or in other words this is non-migratable to other CPUs. Hence, it is not required to run this function in non-preemptible context. Enabling preemption will allow subsequent functions to sleep. Call put_affine_portal() on entry i.e. before calling bman_create_portal() to enable preemption.
