* Revert "PCI: PCIE ASPM support"Greg Kroah-Hartman2008-02-0210-900/+0
| | | | | | | | | | | This reverts commit 6c723d5bd89f03fc3ef627d50f89ade054d2ee3b. It caused build errors on non-x86 platforms, config file confusion, and even some boot errors on some x86-64 boxes.

| | | | | | | | | | | | | | | | | | | | | | | | | | In power_supply_create_attrs(), we create static attributes as referenced by power_supply_static_attrs[i].

This patch fixes it to unregister the correct attrib. Another line which was unnecessarily line wrapped is also unwrapped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CAPACITY_LEVEL stuff defines various levels of charge; however, what is the difference between them? What differentiates between HIGH and NORMAL, LOW and CRITICAL, etc? As it appears that these are fairly arbitrary, we end up making such policy decisions in the kernel (or in hardware). This is the sort of decision that should be made in userspace, not in the kernel. If the hardware does not support _CAPACITY and it cannot be easily calculated, then perhaps the driver should register a custom CAPACITY_LEVEL attribute; however, userspace should not become accustomed to looking for such a thing, and we should certainly not encourage drivers to provide CAPACITY_LEVEL stubs. The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The OLPC battery driver is the only driver making use of this, so it's removed from there as well.

Actually, given the implementation of simple_transaction_get(), buf[-1] is zero, so in both of these cases the subsequent check of the value of buf[size-1] will catch this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neither EPERM and ENOENT map to valid errors for PUTROOTFH according to rfc 3530, and, if anything, ENOENT is likely to be slightly more informative; so don't bother mapping ENOENT to EPERM. (Probably this was originally done because one likely cause was that there is an fsid=0 export but that it isn't permitted to this particular client. Now that we allow WRONGSEC returns, this is somewhat less likely.) In the long term we should work to make this situation less likely, perhaps by turning off nfsv4 service entirely in the absence of the pseudofs root, or constructing a pseudofilesystem root ourselves in the kernel as necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file implements the RDMA transport sendto function. A RPC reply on an RDMA transport consists of some number of RDMA_WRITE requests followed by an RDMA_SEND request. The sendto function parses the ONCRPC RDMA reply header to determine how to send the reply back to the client. The send queue is sized so as to be able to send complete replies for requests in most cases. In the event that there are not enough SQ WR slots to reply, e.g. big data, the send will block the NFSD thread. The I/O callback functions in svc_rdma_transport.c that reap WR completions wake any waiters blocked on the SQ. In general, the goal is not to block NFSD threads and the has_wspace method stall requests when the SQ is nearly full.

The function dequeues work reqeust completion contexts from an I/O list that it shares with the I/O tasklet in svc_rdma_transport.c. For ONCRPC RDMA, an RPC may not be complete when it is received. Instead, the RDMA header that precedes the RPC message informs the transport where to get the RPC data from on the client and where to place it in the RPC message before it is delivered to the server. The svc_rdma_recvfrom function therefore, parses this RDMA header and issues any necessary RDMA operations to fetch the remainder of the RPC from the client. Special handling is required when the request involves an RDMA_READ. In this case, recvfrom submits the RDMA_READ requests to the underlying transport driver and then returns 0. When the transport completes the last RDMA_READ for the request, it enqueues it on a read completion queue and enqueues the transport. The recvfrom code favors this queue over the regular DTO queue when satisfying reads. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Acked-by: Neil Brown <neilb@suse.de> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file implements the core transport data management and I/O path. The I/O path for RDMA involves receiving callbacks on interrupt context. Since all the svc transport locks are _bh locks we enqueue the transport on a list, schedule a tasklet to dequeue data indications from the RDMA completion queue. The tasklet in turn takes _bh locks to enqueue receive data indications on a list for the transport. The svc_rdma_recvfrom transport function dequeues data from this list in an NFSD thread context.

Convenience functions are added to set and get the local and remote addresses of a transport from the transport provider as well as determine the length of a sockaddr. A transport is responsible for setting the xpt_local and xpt_remote addresses in the svc_xprt structure as part of transport creation and xpo_accept processing. This cannot be done in a generic way and in fact varies between TCP, UDP and RDMA. A set of xpo_ functions (e.g. getlocalname, getremotename) could have been added but this would have resulted in additional caching and copying of the addresses around. Note that the xpt_local address should also be set on listening endpoints; for TCP/RDMA this is done as part of endpoint creation. For connected transports like TCP and RDMA, the addresses never change and can be set once and copied into the rqstp structure for each request. For UDP, however, the local and remote addresses may change for each request. In this case, the address information is obtained from the UDP recvmsg info and copied into the rqstp structure from there. A svc_xprt_local_port function was also added that returns the local port given a transport. This is used by svc_create_xprt when returning the port associated with a newly created transport, and later when creating a generic find transport service to check if a service is already listening on a given port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the transport independent sk_deferred list to the svc_xprt structure and updates the svc_deferred_req structure to keep pointers to svc_xprt's directly. The deferral processing code is also moved out of the transport dependent recvfrom functions and into the generic svc_recv path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the authinfo cache to svc_xprt. This allows both the TCP and RDMA transports to share this logic. A flag bit is used to determine if auth information is to be cached or not. Previously, this code looked at the transport protocol. I've also changed the spin_lock/unlock logic so that a lock is not taken for transports that are not caching auth info.
