2011-03-09microblaze: Remove r0_ram pointer and PTO alignmentMichal Simek

2011-03-09nilfs2: get rid of nilfs_sb_info structureRyusuke Konishi
This directly uses sb->s_fs_info to keep a nilfs filesystem object and fully removes the intermediate nilfs_sb_info structure. With this change, the hierarchy of on-memory structures of nilfs will be simplified as follows: Before: super_block -> nilfs_sb_info -> the_nilfs -> cptree --+-> nilfs_root (current file system) +-> nilfs_root (snapshot A) +-> nilfs_root (snapshot B) : -> nilfs_sc_info (log writer structure) After: super_block -> the_nilfs -> cptree --+-> nilfs_root (current file system) +-> nilfs_root (snapshot A) +-> nilfs_root (snapshot B) : -> nilfs_sc_info (log writer structure) The reason why we didn't design so from the beginning is because the initial shape also differed from the above. The early hierachy was composed of "per-mount-point" super_block -> nilfs_sb_info pairs and a shared nilfs object. On the kernel 2.6.37, it was changed to the current shape in order to unify super block instances into one per device, and this cleanup became applicable as the result.

2011-03-09ARM: 6777/1: gic: Add hooks for architecture specific extensionsSantosh Shilimkar
Few architectures combine the GIC with an external interrupt controller. On such systems it may be necessary to update both the GIC registers and the external controller's registers to control IRQ behavior. This can be addressed in couple of possible methods. 1. Export common GIC routines along with 'struct irq_chip gic_chip' and allow architectures to have custom function by override. 2. Provide architecture specific function pointer hooks within GIC library and leave platforms to add the necessary code as part of these hooks. First one might be non-intrusive but have few shortcomings like arch needs to have there own custom gic library. Locks used should be common since it caters to same IRQs etc. Maintenance point of view also it leads to multiple file fixes. The second probably is cleaner and portable. It ensures that all the common GIC infrastructure is not touched and also provides archs to address their specific issue.
