UBUNTU: reduce disk usage during buildd builds
BugLink: http://bugs.launchpad.net/bugs/645653
For each flavour build we keep all of intermediate trees intact.
This allows simple incremental updates in a development environment but
leads to very large disk footprints on the build. For Maverick with three
flavours we are seeing 19GB for i386 and 25GB for amd64. Anything over
15GB is likely to run the buildds out of disk and fail the build.
When building on a buildd (in full_build=true mode) clean out
the main build tree and the package tree for the debugging deb.
This reduces consumption to more like 10GB maximum regardless of
the flavour count.

omap_hsmmc: Ensure regulator enable / disable are paired
Without this the kernel fails to initialize the SDHC card and find the
root partition. Work is currently underway with the community to find a
real solution to the problem. This a temporary measure to unblock
developers and will have to be reverted when the real fix gets upstream.

UBUNTU: SAUCE: fix pv-ops for legacy Xen
Import fix_xen_guest_on_old_EC2.patch from fedora 14
Legacy hypervisors (RHEL 5.0 and RHEL 5.1) do not handle guest writes to
cr4 gracefully. If a guest attempts to write a bit of cr4 that is
unsupported, then the HV is so offended it crashes the domain. While
later guest kernels (such as RHEL6) don't assume the HV supports all
features, they do expect nicer responses. That assumption introduced
code that probes whether or not xsave is supported early in the boot. So
now when attempting to boot a RHEL6 guest on RHEL5.0 or RHEL5.1 an early
crash will occur.
This patch is quite obviously an undesirable hack. The real fix for this
problem should be in the HV, and is, in later HVs. However, to support
running on old HVs, RHEL6 can take this small change. No impact will
occur for running on any RHEL HV (not even RHEL 5.5 supports xsave).
There is only potential for guest performance loss on upstream Xen.
All this by way of explanation for why is this patch not going upstream.

Allow broken Lucid userspace tools to load policy, on Maverick kernel.
The fix for http://launchpad.net/bugs/581525 blocks Lucid tools from

reintroducing the bug.
The apparmor_parser when compiling policy could generate invalid dfas
that did not have sufficient padding to avoid invalid references, when
used by the kernel. The kernels check to verify the next/check table
size was broken meaning invalid dfas were being created by userspace

To remain compatible with old tools that are not fixed, pad the loaded
dfas next/check table. The dfa's themselves are valid except for the
high padding for potentially invalid transitions (high bounds error),
which have a maximimum is 256 entries. So just allocate an extra null filled
256 entries for the next/check tables. This will guarentee all bounds
are good and invalid transitions go to the null (0) state.

+ write the value to the XINO file using a workqueue

Since the workqueue handles the request one by one, both of processA and
B waits forever.

(A commit in a series of introducing pid map/tree and making sure to
acquire sbinfo lock in deleting inode. While every commit is
git-bisect-able, you shoule read all commits in the series since a
single commit may have less meaning.)
s_umount rwsem in struct super_block prevents a race condition among
umount, remount and kswapd. It is good.
But if an inode is going to be deleted by other than kswapd, aufs may be
doing another operation which requires a lock for sbinfo. In this case,
si_noflush_read_trylock() in au_iinfo_fin() will not acquire the
lock. Before au_iinfo_fin() completes or during its operations, another
operation may release the lock and remount or a branch management
process may start. Here if the branch management process changes the
union members, then xino management in au_iinfo_fin() will not work
correctly.
In order to fix this potential problem, there another bad approch is
introduced which uses a bitmap to mark the pid which acquired the sbinfo
lock. In au_iinfo_fin(), if the bit is set, then the function will not
try acquiring the lock.
To support the pid larger than PID_MAX_DEFAULT, sbinfo prepares a radix
tree too.
With this commit, we can remove si_noflush_read_trylock(). But it will
be necessary in aufs2-31 branch, so leave it now.

aufs: possible bugfix, revalidate inode race between readdir and lookup
Both of readdir and lookup operation need to assign the aufs inode
number, but it requires other aufs locks including xi_nondir_mtx which
prevents hard-linked inode number from race condition. There can happen
a violation of the order of these locks.
They acquire these locks.
aufs_readdir("./dirA")
+ si_read_lock
+ fi_write_lock
+ di_write_lock
+ ii_write_lock for dirA
+ xi_nondir_mtx for non-dir
aufs_lookup("./dirA/fileB")
+ si_read_lock
+ di_write_lock
+ xi_nondir_mtx for non-dir
+ ii_write_lock_nested for fileB
Here the fileB may be in copy-up operation which acquires the parent's
dentry-info and inode->info lock. So aufs_lookup() waits for the
completion of copy-up, aufs_readdir() waits for xi_nondir_mtx, and the
copy-up waits for the parent, but it is held by readdir.
This is very complicated situation and I am afraid the design of aufs
inode assignment is not godd. But I don't have other idea.
This commit refines xi_nondir_mtx and releases it before
"ii_write_lock_nested for fileB."

UBUNTU: SAUCE: Yama: verify inode is symlink to avoid bind mounts
The inode_follow_link LSM hook is called in bind mount situations as
well as for symlink situations, so we must explicitly check for the
inode being a symlink to not reject bind mounts in 1777 directories,
which seems to be a common NFSv4 configuration.
