2012-06-29NFS: Use nfs4_destroy_server() to clean up NFS v4Bryan Schumaker4-22/+9
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>
2012-06-29NFS: set_pnfs_layoutdriver() from nfs4_proc_fsinfo()Bryan Schumaker2-2/+7
The generic client doesn't need to know about pnfs layout drivers, so this should be done in the v4 code. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2012-06-28NFS: Cleanup - only store the write verifier in struct nfs_pageTrond Myklebust6-16/+26
The 'committed' field is not needed once we have put the struct nfs_page on the right list. Also correct the type of the verifier: it is not an array of __be32, but simply an 8 byte long opaque array. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2012-06-28NFS: Let xdr_read_pages() check for buffer overflowsTrond Myklebust3-72/+12
xdr_read_pages will already do all of the buffer overflow checks that are currently being open-coded in the various callers. This patch simplifies the existing code by replacing the open coded checks. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-06-28SUNRPC: xdr_read_pages should return the amount of XDR encoded page dataTrond Myklebust2-4/+7

2012-06-28SUNRPC: Don't decode beyond the end of the RPC reply messageTrond Myklebust2-7/+22
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.

2012-06-28SUNRPC: Clean up xdr_set_iov()Trond Myklebust1-7/+7

2012-06-24NFSv2/v3: Remove incorrect dprintks from the readdir reply codeTrond Myklebust2-16/+4
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.

2012-06-23ARM: Orion: Fix Virtual/Physical mixup with watchdogAndrew Lunn5-2/+5
The orion watchdog is expecting to be passed the physcial address of the hardware, and will ioremap() it to give a virtual address it will use as the base address for the hardware. However, when creating the platform resource record, a virtual address was being used. Add the necassary #define's so we can pass the physical address as expected. Tested on Kirkwood and Orion5x.

A custom variant of clock gating, that calls a custom function before gating the clock off, has been introduced. However in clk_register_gate_fn() this custom function "fn" is never assigned.

2012-06-23ARM: Orion5x - Restore parts of io.h, with reworkAndrew Lunn2-0/+23
Commit 4d5fc58dbe34b78157c05b319669bb3e064ba8bd (ARM: remove bunch of now unused mach/io.h files) removed the orion5x io.h. 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.

2012-06-21ARM: OMAP4: hwmod data: Force HDMI in no-idle while enabledRicardo Neri1-0/+5
As per the OMAP4 documentation, audio over HDMI must be transmitted in no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses no-idle/force-idle settings instead of smart-idle mode. This is required as the DSS interface clock is used as functional clock for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could be choppy, have bad quality or not be audible at all.

Until the OMAP4 code is converted to disable the use of the clock framework-based clockdomain enable/disable sequence, any clock used as a hwmod main_clk must have a clockdomain associated with it.
