Merge branch 'akpm' (patchbomb from Andrew Morton)
Merge incoming from Andrew Morton: - Various misc things. - arch/sh updates. - Part of ocfs2. Review is slow. - Slab updates. - Most of -mm. - printk updates. - lib/ updates. - checkpatch updates. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (226 commits) checkpatch: update $declaration_macros, add uninitialized_var checkpatch: warn on missing spaces in broken up quoted checkpatch: fix false positives for --strict "space after cast" test checkpatch: fix false positive MISSING_BREAK warnings with --file checkpatch: add test for native c90 types in unusual order checkpatch: add signed generic types checkpatch: add short int to c variable types checkpatch: add for_each tests to indentation and brace tests checkpatch: fix brace style misuses of else and while checkpatch: add --fix option for a couple OPEN_BRACE misuses checkpatch: use the correct indentation for which() checkpatch: add fix_insert_line and fix_delete_line helpers checkpatch: add ability to insert and delete lines to patch/file checkpatch: add an index variable for fixed lines checkpatch: warn on break after goto or return with same tab indentation checkpatch: emit a warning on file add/move/delete checkpatch: add test for commit id formatting style in commit log checkpatch: emit fewer kmalloc_array/kcalloc conversion warnings checkpatch: improve "no space after cast" test checkpatch: allow multiple const * types ...
