2011-03-28sony-laptop: ignore hard switch rfkill events (SPIC)Mattia Dongili
There is not much use for these events in userspace and handling the events themselves seems to get in the way of the actual activation of the rf devices. The SNC device doesn't expose them already. https://bugzilla.kernel.org/show_bug.cgi?id=15303 Signed-off-by: Mattia Dongili <malattia@linux.it> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem). Tested with modified (to reproduce this bug) myri10ge driver. Cc: stable@kernel.org # 2.6.37+ Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: David S.

2011-03-27NFS: Fix a hang in the writeback pathTrond Myklebust
Now that the inode scalability patches have been merged, it is no longer safe to call igrab() under the inode->i_lock. Now that we no longer call nfs_clear_request() until the nfs_page is being freed, we know that we are always holding a reference to the nfs_open_context, which again holds a reference to the path, and so the inode cannot be freed until the last nfs_page has been removed from the radix tree and freed. We can therefore skip the igrab()/iput() altogether. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2011-03-27genirq: Split irq_set_affinity() so it can be called with lock held.David Daney
The .irq_cpu_online() and .irq_cpu_offline() functions may need to adjust affinity, but they are called with the descriptor lock held.

2011-03-27mfd: Add MAX8997/8966 IRQ controlMyungJoo Ham
This patch enables IRQ handling for MAX8997/8966 chips. Please note that Fuel-Gauge-related IRQs are not implemented in this initial release. The fuel gauge module in MAX8997 is identical to MAX17042, which is already in Linux kernel. In order to use the already-existing MAX17042 driver for fuel gauge module in MAX8997, the main interrupt handler of MAX8997 should relay related interrupts to MAX17042 driver. However, in order to do this, we need to modify MAX17042 driver as well because MAX17042 driver does not have any interrupt handlers for now. We are not going to implement this in this initial release as it is not crucial in basic operations of MAX8997.

2011-03-27mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to itAndres Salomon
Replace mfd_shared_platform_driver_register with mfd_clone_cell. The former was called by an mfd client, and registered both a platform driver and device. The latter is called by an mfd driver, and registers only a platform device. The downside of this is that mfd drivers need to be modified whenever new clients are added that share a cell; the upside is that it fits Linux's driver model better. It's also simpler. This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to them via platform drivers.

2011-03-26Regulator: add suspend-finish API for regulator core.MyungJoo Ham
The regulator core had suspend-prepare that turns off the regulators when entering a system-wide suspend. However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

2011-03-25mmc: tmio: convert the SDHI MMC driver from MFD to a platform driverGuennadi Liakhovetski
On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO MFD cell driver. Now that the tmio_mmc driver has been split into a core and a separate MFD glue, we can support SDHI natively without the need to emulate an MFD controller. This also allows to support systems with an on-SoC SDHI controller and a separate MFD with a TMIO core.

2011-03-24fs: rename inode_lock to inode_hash_lockDave Chinner
All that remains of the inode_lock is protecting the inode hash list manipulation and traversals. Rename the inode_lock to inode_hash_lock to reflect it's actual function. Signed-off-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-03-24fs: move i_wb_list out from under inode_lockDave Chinner
Protect the inode writeback list with a new global lock inode_wb_list_lock and use it to protect the list manipulations and traversals. This lock replaces the inode_lock as the inodes on the list can be validity checked while holding the inode->i_lock and hence the inode_lock is no longer needed to protect the list.

2011-03-24fs: protect inode->i_state with inode->i_lockDave Chinner
Protect inode state transitions and validity checks with the inode->i_lock. This enables us to make inode state transitions independently of the inode_lock and is the first step to peeling away the inode_lock from the code. This requires that __iget() is done atomically with i_state checks during list traversals so that we don't race with another thread marking the inode I_FREEING between the state check and grabbing the reference. Also remove the unlock_new_inode() memory barrier optimisation required to avoid taking the inode_lock when clearing I_NEW. Simplify the code by simply taking the inode->i_lock around the state change and wakeup. Because the wakeup is no longer tricky, remove the wake_up_inode() function and open code the wakeup where necessary.

2011-03-24lib, arch: add filter argument to show_mem and fix private implementationsDavid Rientjes
Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which resulted in build warnings on all architectures that implement their own versions of show_mem(): lib/lib.a(show_mem.o): In function `show_mem': show_mem.c:(.text+0x1f4): multiple definition of `show_mem' arch/sparc/mm/built-in.o:(.text+0xd70): first defined here The fix is to remove __show_mem() and add its argument to show_mem() in all implementations to prevent this breakage. Architectures that implement their own show_mem() actually don't do anything with the argument yet, but they could be made to filter nodes that aren't allowed in the current context in the future just like the generic implementation.
