| * MIPS: Remove redundant addr_limit assignment on exec.Mathias Krause2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address limit is already set in flush_old_exec() via set_fs(USER_DS) so this assignment is redundant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 6be63bbbdab66b9185dc6f67c8b1bacb6f37f946 (lmo) rsp. af3a1f6f4813907e143f87030cde67a9971db533 (kernel.org) the Malta code does no longer probe for presence of GCMP if CMP is not configured. This means that the variable gcmp_present well be left at its default value of -1 which normally is meant to indicate that GCMP has not yet been mmapped. This non-zero value is now interpreted as GCMP being present resulting in a write attempt to a GCMP register resulting in a crash.

| * | | ext3: Fix data corruption in inodes with journalled dataJan Kara2011-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When journalling data for an inode (either because it is a symlink or because the filesystem is mounted in data=journal mode), ext3_evict_inode() can discard unwritten data by calling truncate_inode_pages(). This is because we don't mark the buffer / page dirty when journalling data but only add the buffer to the running transaction and thus mm does not know there are still unwritten data. Fix the problem by carefully tracking transaction containing inode's data, committing this transaction, and writing uncheckpointed buffers when inode should be reaped.

| * | | ext2: check xattr name_len before acquiring xattr_sem in ext2_xattr_getWang Sheng-Hui2011-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ext2_xattr_get(), the code will acquire xattr_sem first, later checks the length of xattr name_len > 255. It's unnecessarily time consuming and also ext2_xattr_set() checks the length before other checks. So move the check before acquiring xattr_sem to make these two functions consistent.
