2008-07-16hwmon: (ad7418) Convert to a new-style i2c driverJean Delvare1-83/+26
The ad7418 driver is only used on embedded platforms where i2c devices can easily be declared in platform code. Thus a new-style i2c driver makes perfect sense. This lets us get rid of quirky detection code (these chips have no identification registers) and shrinks the binary driver size by 38%.

The new-style pca9539 driver implements the optional detect() callback to cover the use cases of the legacy driver. Warning: users will now have to use the force module parameter to get the driver to attach to their device. That's not a bad thing as these devices can't be detected anyway.

Clear i2c_adapter.dev on adapter removal. This makes it possible to re-add the adapter at a later point, which some drivers (i2c-amd756-s4882, i2c-nforce2-s4985) actually do.

2008-07-16x86/PCI: ACPI based PCI gap calculationAlok Kataria1-0/+80
Using ACPI to find free address space allows us to find a gap for the unallocated PCI resources or MMIO resources for hotplug devices within the BIOS allowed PCI regions. It works by evaluating the _CRS object under PCI0 looking for producer resources. Then searches the e820 memory space for a gap within these producer resources.

2008-07-16SUNRPC: Remove the BKL from the callback functionsTrond Myklebust5-9/+17

2008-07-16NFS: Remove BKL from NFS lookup codeTrond Myklebust1-8/+1
All dentry-related operations are already BKL-safe, since they are protected by the VFS locking. No extra locks should be needed in the NFS code. In the case of nfs_revalidate_inode(), we're only doing an attribute update (protected by the inode->i_lock). In the case of nfs_lookup(), we're instantiating a new dentry, so there should be no contention possible until after we call d_materialise_unique.

2008-07-16NFS: Remove BKL requirement from attribute updatesTrond Myklebust2-11/+71
The main problem is dealing with inode->i_size: we need to set the inode->i_lock on all attribute updates, and so vmtruncate won't cut it. Make an NFS-private version of vmtruncate that has the necessary locking semantics. The result should be that the following inode attribute updates are protected by inode->i_lock nfsi->cache_validity nfsi->read_cache_jiffies nfsi->attrtimeo nfsi->attrtimeo_timestamp nfsi->change_attr nfsi->last_updated nfsi->cache_change_attribute nfsi->access_cache nfsi->access_cache_entry_lru nfsi->access_cache_inode_lru nfsi->acl_access nfsi->acl_default nfsi->nfs_page_tree nfsi->ncommit nfsi->npages nfsi->open_files nfsi->silly_list nfsi->acl nfsi->open_states inode->i_size inode->i_atime inode->i_mtime inode->i_ctime inode->i_nlink inode->i_uid inode->i_gid The following is protected by dir->i_mutex nfsi->cookieverf Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-07-16nfs: set correct fl_len in nlmclnt_test()Felix Blyakher1-1/+1
fcntl(F_GETLK) on an nfs client incorrectly returns the values for the conflicting lock. fl_len value is always 1. If the conflicting lock is (0, 4095) the F_GETLK request for (1024, 10) returns (0, 1), which doesn't even cover the requested range, and is quite confusing. The fix is trivial, set fl_end from the fl_end value recieved from the nfs server. Signed-off-by: Felix Blyakher <felixb@sgi.com> Signed-off-by: "J.

2008-07-16SUNRPC: Support registering IPv6 interfaces with local rpcbind daemonChuck Lever2-4/+177
Introduce a new API to register RPC services on IPv6 interfaces to allow the NFS server and lockd to advertise on IPv6 networks. Unlike rpcb_register(), the new rpcb_v4_register() function uses rpcbind protocol version 4 to contact the local rpcbind daemon. The version 4 SET/UNSET procedures allow services to register address families besides AF_INET, register at specific network interfaces, and register transport protocols besides UDP and TCP. All of this functionality is exposed via the new rpcb_v4_register() kernel API. A user-space rpcbind daemon implementation that supports version 4 of the rpcbind protocol is required in order to make use of this new API. Note that rpcbind version 3 is sufficient to support the new rpcbind facilities listed above, but most extant implementations use version 4.
