SELinux fixups needed for preemptable RCU from -rt
SELinux: no BUG_ON(!ss_initialized) in selinux_clone_mnt_opts
---------------------------
-What: Solaris/SunOS syscall and binary support on Sparc
-When: 2.6.26
-Why: Largely unmaintained and almost entirely unused. File system
- layering used to divert library and dynamic linker searches to
- /usr/gnemul is extremely buggy and unfixable. Making it work
- is largely pointless as without a lot of work only the most
- trivial of Solaris binaries can work with the emulation code.
-Who: David S. Miller <davem@davemloft.net>
-
----------------------------
-
What: init_mm export
When: 2.6.26
Why: Not used in-tree. The current out-of-tree users used it to
uses the 32-bit UID system calls properly otherwise.
This affects at least:
- SunOS emulation
- Solaris emulation
iBCS on Intel
sparc32 emulation on sparc64

- This allows you to run most SunOS binaries. If you want to do this,
- say Y here and place appropriate files in /usr/gnemul/sunos. See
- <http://www.ultralinux.org/faq.html> for more information. If you
- want to run SunOS binaries on an Ultra you must also say Y to
- "Kernel support for 32-bit a.out binaries" above.

- * udf_lookup
- *
- * PURPOSE
- * Look-up the inode for a given name.
- *
- * DESCRIPTION
- * Required - lookup_dentry() will return -ENOTDIR if this routine is not
- * available for a directory. The filesystem is useless if this routine is
- * not available for at least the filesystem's root directory.
- *
- * This routine is passed an incomplete dentry - it must be completed by
- * calling d_add(dentry, inode). If the name does not exist, then the
- * specified inode must be set to null. An error should only be returned
- * when the lookup fails for a reason other than the name not existing.
- * Note that the directory inode semaphore is held during the call.
- *
- * Refer to lookup_dentry() in fs/namei.c
- * lookup_dentry() -> lookup() -> real_lookup() -> .
- *
- * PRE-CONDITIONS
- * dir Pointer to inode of parent directory.
- * dentry Pointer to dentry to complete.
- * nd Pointer to lookup nameidata
- *
- * POST-CONDITIONS
- * <return> Zero on success.
- *
- * HISTORY
- * July 1, 1997 - Andrew E. Mileski
- * Written, tested, and released.

- * udf_set_blocksize

- * PURPOSE

- * DESCRIPTION
- * To allow room for a DMA transfer, it is best to guess big when unsure.
- * This routine picks 2048 bytes as the blocksize when guessing. This
- * should be adequate until devices with larger block sizes become common.
- *
- * Note that the Linux kernel can currently only deal with blocksizes of
- * 512, 1024, 2048, 4096, and 8192 bytes.
- *
- * PRE-CONDITIONS
- * sb Pointer to _locked_ superblock.
- *
- * POST-CONDITIONS
- * sb->s_blocksize Blocksize.
- * sb->s_blocksize_bits log2 of blocksize.
- * <return> 0 Blocksize is valid.
- * <return> 1 Blocksize is invalid.
- *
- * HISTORY
- * July 1, 1997 - Andrew E. Mileski
- * Written, tested, and released.
