2014-03-20Btrfs: cache extent states in defrag code pathFilipe Manana
When locking file ranges in the inode's io_tree, cache the first extent state that belongs to the target range, so that when unlocking the range we don't need to search in the io_tree again, reducing cpu time and making and therefore holding the io_tree's lock for a shorter period.

2014-03-20Btrfs: fix deadlock with nested trans handlesJosef Bacik
Zach found this deadlock that would happen like this btrfs_end_transaction <- reduce trans->use_count to 0 btrfs_run_delayed_refs btrfs_cow_block find_free_extent btrfs_start_transaction <- increase trans->use_count to 1 allocate chunk btrfs_end_transaction <- decrease trans->use_count to 0 btrfs_run_delayed_refs lock tree block we are cowing above ^^ We need to only decrease trans->use_count if it is above 1, otherwise leave it alone. This will make nested trans be the only ones who decrease their added ref, and will let us get rid of the trans->use_count++ hack if we have to commit the transaction.

2014-03-20rcu: Provide grace-period piggybacking APIPaul E. McKenney
The following pattern is currently not well supported by RCU: 1. Make data element inaccessible to RCU readers. 2. Do work that probably lasts for more than one grace period. 3. Do something to make sure RCU readers in flight before #1 above have completed. Here are some things that could currently be done: a. Do a synchronize_rcu() unconditionally at either #1 or #3 above. This works, but imposes needless work and latency. b. Post an RCU callback at #1 above that does a wakeup, then wait for the wakeup at #3. This works well, but likely results in an extra unneeded grace period. Open-coding this is also a bit more semi-tricky code than would be good. This commit therefore adds get_state_synchronize_rcu() and cond_synchronize_rcu() APIs. Call get_state_synchronize_rcu() at #1 above and pass its return value to cond_synchronize_rcu() at #3 above. This results in a call to synchronize_rcu() if no grace period has elapsed between #1 and #3, but requires only a load, comparison, and memory barrier if a full grace period did elapse.

2014-03-20x86, cpu: Add forcepae parameter for booting PAE kernels on PAE-disabled ↵Chris Bainbridge
Pentium M Many Pentium M systems disable PAE but may have a functionally usable PAE implementation.

2014-03-20x86: Load the 32-bit vdso in place, just like the 64-bit vdsosAndy Lutomirski
This replaces a decent amount of incomprehensible and buggy code with much more straightforward code. It also brings the 32-bit vdso more in line with the 64-bit vdsos, so maybe someday they can share even more code. This wastes a small amount of kernel .data and .text space, but it avoids a couple of allocations on startup, so it should be more or less a wash memory-wise.

This makes the generic of_mdiobus_register parse the DT compatible string for the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that matches the phy-id register normally readable through MDIO. When the ID is given the phy autoprobing is defeated and the phy is created directly. This is necessary to support phy's that cannot be autoprobed when of_mdiobus_register is called. Specifically, my case has the phy in reset at of_mdiobus_register, the reset is only released once the ethernet driver starts, before it attaches to the phy.

Since all the VF interaction with the firmware passes through the PF driver, we can emulate to the VF they have one port, and further create a set of the VFs which act on port1 of the device and another set which acts on port2. Series done against net-next commit 3ab428a "netfilter: Add missing vmalloc.h include to nft_hash.c" Roland, we send this through netdev, but if you have comments, will love to hear them. ==================== Signed-off-by: David S.

2014-03-20net/mlx4: Adapt num_vfs/probed_vf params for single port VFMatan Barak
A new syntax is added for the module parameters num_vfs and probe_vf. num_vfs=p1,p2,p1+p2 probe_bf=p1,p2,p1+p2 Where p1(2) is the number of VFs on / probed VFs for physical port1(2) and p1+p2 is the number of dual port VFs. Single port VFs are currently supported only when the link type for both ports of the device is Ethernet.

2014-03-20net/mlx4: Adapt code for N-Port VFMatan Barak
Adds support for N-Port VFs, this includes: 1. Adding support in the wrapped FW command In wrapped commands, we need to verify and convert the slave's port into the real physical port. Furthermore, when sending the response back to the slave, a reverse conversion should be made. 2. Adjusting sqpn for QP1 para-virtualization The slave assumes that sqpn is used for QP1 communication. If the slave is assigned to a port != (first port), we need to adjust the sqpn that will direct its QP1 packets into the correct endpoint. 3. Adjusting gid[5] to modify the port for raw ethernet In B0 steering, gid[5] contains the port. It needs to be adjusted into the physical port. 4. Adjusting number of ports in the query / ports caps in the FW commands When a slave queries the hardware, it needs to view only the physical ports it's assigned to. 5. Adjusting the sched_qp according to the port number The QP port is encoded in the sched_qp, thus in modify_qp we need to encode the correct port in sched_qp.

2014-03-20net/mlx4: Add utils for N-Port VFsMatan Barak
This patch adds the following utils: 1. Convert slave_id -> VF 2. Get the active ports by slave_id 3. Convert slave's port to real port 4. Get the slave's port from real port 5. Get all slaves that uses the i'th real port 6. Get all slaves that uses the i'th real port exclusively Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.

2014-03-20net/mlx4: Add data structures to support N-Ports per VFMatan Barak
Adds the required data structures to support VFs with N (1 or 2) ports instead of always using the number of physical ports. Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-03-20IB/mlx4_ib: Adapt code to use caps.num_ports instead of a constantMatan Barak
Some code in the mlx4 IB driver stack assumed MLX4_MAX_PORTS ports. Instead, we should only loop until the number of actual ports in i the device, which is stored in dev->caps.num_ports.
