2010-05-30ia64: revert __node_random additionLinus Torvalds
This partially reverts commit 4ec37de89d8c758ee8115e0e64b3f994910789ee ("[IA64] Fix build breakage"), since the commit that made it necessary got reverted earlier (see commit 35926ff5fba8, 'Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"') Even if we ever re-introduce this, there is no reason to make __node_random be some architecture-specific function.

2010-05-30Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"Linus Torvalds
This reverts commit 0ac0c0d0f837c499afd02a802f9cf52d3027fa3b, which caused cross-architecture build problems for all the wrong reasons. IA64 already added its own version of __node_random(), but the fact is, there is nothing architectural about the function, and the original commit was just badly done. Revert it, since no fix is forthcoming. Requested-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-05-30parisc: Call pagefault_disable/pagefault_enable in kmap_atomic/kunmap_atomicJohn David Anglin
Based on the generic implementation of kmap_atomic and kunmap_atomic, we should call pagefault_disable and pagefault_enable in our PA8000 implementation. The define for kmap_atomic_prot was also missing, and I updated kmap_atomic_pfn to use the generic implementation because of the change to kmap_atomic.

2010-05-27rename the generic fsync implementationsChristoph Hellwig
We don't name our generic fsync implementations very well currently. The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-05-28mfd: New AB8500 driverRabin Vincent
Add a new driver to support the AB8500 Power Management chip, replacing the current AB4500. The new driver replaces the old one, instead of an incremental modification, because this is a substantial overhaul including: - Split of the driver into -core and -spi portions, to allow another interface layer to be added - Addition of interrupt support - Switch to MFD core API for handling subdevices - Simplification of the APIs to remove a redundant block parameter - Rename of the APIs and macros from ab4500_* to ab8500_* - Rename of the files from ab4500* to ab8500* - Change of the driver name from ab4500 to ab8500 Acked-by: Linus Walleij <linus.walleij@stericsson.com> Acked-by: Srinidhi Kasagar <srinidhi.kasagar@stericsson.com> Signed-off-by: Rabin Vincent <rabin.vincent@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
