2012-05-14NFS: Turn v3 on by defaultBryan Schumaker
Most users will use NFS v3 or possibly v4 so this makes it easier for them. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Make v2 configurableBryan Schumaker
With this patch NFS v2 can be disabled during Kconfig. I default the option to "y" to match the current behavior. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Create an NFS v3 stat_to_errno()Bryan Schumaker
In theory, NFS v3 can have different error versions than NFS v2. v4 is already using its own nfs4_stat_to_errno() to map error codes, so rather than create something in the generic client for v2 and v3 to share I instead give v3 its own function. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Pass mntfh as part of the nfs_mount_info structureBryan Schumaker
This allows me to use the filehandle allocated in nfs_fs_mount() for nfs v4 mounts instead of allocating a new one. Rather than change nfs4_mount() to look almost exactly like nfs_fs_mount(), I instead remove the function.

2012-05-14NFS: Create a single nfs_validate_mount_data() functionBryan Schumaker

2012-05-14NFS: Create a single function for text mount dataBryan Schumaker
The v2/3 and v4 cases were very similar, with just a few parameters changed. This makes it easy to share code. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Create a new nfs_try_mount()Bryan Schumaker
This function returns the same same return type as nfs4_try_mount() so they two can be more easily substituted. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Let mount data parsing set the NFS versionBryan Schumaker
This field is unconditionally set while parsing mount data, so there is no need to fill it in here. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2012-05-14NFS: Use nfs_fs_mount_common() for xdev mountsBryan Schumaker
At this point, there are only a few small differences between these two functions. I can set a few function pointers in the nfs_mount_info struct to get around these differences. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Create a common xdev_mount() functionBryan Schumaker
The only difference between nfs_xdev_mount() and nfs4_xdev_mount() is the clone_super() function called to clone the super block. I can combine these two functions by using the fill_super field in the mount_info structure. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Create a common fs_mount() functionBryan Schumaker
The nfs4_remote_mount() function was only slightly different from the nfs_fs_mount() function used by the generic client. I created a new nfs_mount_info structure to set different parameters to help combine these functions. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Remove NFS4_MOUNT_UNSHAREDBryan Schumaker
This flag is numerically equivalent to NFS_MOUNT_UNSHARED, so I can remove it to make collapsing functions more straightforward. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Don't pass mount data to nfs_fscache_get_super_cookie()Bryan Schumaker
I intend on creating a single nfs_fs_mount() function used by all our mount paths. To avoid checking between new mounts and clone mounts, I instead pass both structures to a new function in super.c that finds the cache key and then looks up the super cookie. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Create a single nfs_get_root()Bryan Schumaker
This patch splits out the NFS v4 specific functionality of nfs4_get_root() into its own rpc_op called by the generic client, and leaves nfs4_proc_get_rootfh() as its own stand alone function. This also allows me to change nfs4_remote_mount(), nfs4_xdev_mount() and nfs4_remote_referral_mount() to use the generic client's nfs_get_root() function. Later patches in this series will collapse these functions into one common function, so using the same get_root() function everywhere simplifies future changes. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-05-14NFS: Rename nfs4_proc_get_root()Bryan Schumaker
This function is really getting the root filehandle and not the root dentry of the filesystem. I also removed the rpc_ops lookup from nfs4_get_rootfh() under the assumption that if we reach this function then we already know we are using NFS v4.

2012-05-14stmmac: add mixed burst for DMAGiuseppe CAVALLARO
In mixed burst (MB) mode, the AHB master always initiates the bursts with fixed-size when the DMA requests transfers of size less than or equal to 16 beats. This patch adds the MB support and the flag that can be passed from the platform to select it.

2012-05-14stmmac: extend mac addr reg and fix perfect fileringGiuseppe CAVALLARO
This patch is to extend the number of MAC address registers for 16 to 32. In fact, other new 16 registers are available in new chips and this can help on perfect filter mode for unicast.

2012-05-14target: Fix SPC-2 RELEASE bug for multi-session iSCSI client setupsBernhard Kohl
This patch addresses a bug in a special case for target core SPC-2 RELEASE logic where the same physical client (eg: iSCSI InitiatorName) with differing iSCSI session identifiers (ISID) is allowed to incorrectly release the same client's SPC-2 reservation from the non reservation holding path. Note this bug is specific to iscsi-target w/ SPC-2 reservations, and with the default enforce_pr_isids=1 device attr setting in target-core controls if a InitiatorName + different ISID reservations are handled the same as a single iSCSI client entity.

2012-05-14x86/mce: Only restart instruction after machine check recovery if it is safeTony Luck
Section 15.3.1.2 of the software developer manual has this to say about the RIPV bit in the IA32_MCG_STATUS register: RIPV (restart IP valid) flag, bit 0 — Indicates (when set) that program execution can be restarted reliably at the instruction pointed to by the instruction pointer pushed on the stack when the machine-check exception is generated. When clear, the program cannot be reliably restarted at the pushed instruction pointer. We need to save the state of this bit in do_machine_check() and use it in mce_notify_process() to force a signal; even if memory_failure() says it made a complete recovery ... e.g. replaced a clean LRU page.

2012-05-14workqueue: skip nr_running sanity check in worker_enter_idle() if trustee is ↵Tejun Heo
active worker_enter_idle() has WARN_ON_ONCE() which triggers if nr_running isn't zero when every worker is idle. This can trigger spuriously while a cpu is going down due to the way trustee sets %WORKER_ROGUE and zaps nr_running. It first sets %WORKER_ROGUE on all workers without updating nr_running, releases gcwq->lock, schedules, regrabs gcwq->lock and then zaps nr_running. If the last running worker enters idle inbetween, it would see stale nr_running which hasn't been zapped yet and trigger the WARN_ON_ONCE(). Fix it by performing the sanity check iff the trustee is idle. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Cc: stable@vger.kernel.org
