* NFS: Use nfs4_destroy_server() to clean up NFS v4Bryan Schumaker2012-06-29
| | | | | | | | | I can use this function to return delegations and unset the pnfs layout driver rather than continuing to do these things in the generic client. With this change, we no longer need an nfs4_kill_super(). Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | Now that xdr_inline_decode() will automatically cross into the page buffers, we need to ensure that it doesn't exceed the total reply message length. This patch sets up a counter that tracks the number of words remaining in the reply message, and ensures that xdr_inline_decode, xdr_read_pages and xdr_enter_page respect the end of message boundary.

* NFSv2/v3: Remove incorrect dprintks from the readdir reply codeTrond Myklebust2012-06-24
| | | | | | | | | | The actual size of the directory is unknown to the client, so it is always requesting the maximum number it can handle. If the server is replying with fewer entries than was requested, then that will usually reflect the fact that we've hit the end of the directory. Flagging it as an error is therefore incorrect.

| * KVM: PPC: Book3S HV: Drop locks around call to kvmppc_pin_guest_pagePaul Mackerras2012-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we call kvmppc_pin_guest_page() in kvmppc_update_vpa() with two spinlocks held: the vcore lock and the vcpu->vpa_update_lock. This is not good, since kvmppc_pin_guest_page() calls down_read() and get_user_pages_fast(), both of which can sleep. This bug was introduced in 2e25aa5f ("KVM: PPC: Book3S HV: Make virtual processor area registration more robust"). This arranges to drop those spinlocks before calling kvmppc_pin_guest_page() and re-take them afterwards. Dropping the vcore lock in kvmppc_run_core() means we have to set the vcore_state field to VCORE_RUNNING before we drop the lock, so that other vcpus won't try to run this vcore.

Unfortunately, this is still needed for the definition of IO_SPACE_LIMIT which overrides the default 64K. All Orion based systems have 1Mbyte of IO space per PCI[e] bus, and try to request_resource() this size. Orion5x has two such PCI buses. It is likely that the original, removed version, was broken. This version might be less broken. However, it has not been tested on hardware with a PCI card, let alone hardware with a PCI card with IO capabilities.
