Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.
In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

With board files, all I2C busses run at 400KHz. Fix the device-tree
to be consistent with this. It's possible this is incorrect, but at
least it keeps the board files and device-tree consistent.
Also, disable any I2C controllers that the board files don't register,
also for consistency.

The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.
In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.

There are no drivers in the kernel at present which can make use of the
memory reserved by /memreserve/, so there is no point reserving it. Remove
/memreserve/ to allow the user more memory. It's also unclear whether any
future driver would actually require /memreserve/, or allocate memory
through some other mechanism.

The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(),
ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These
are wrapper macros for ext2_*_bit() which need to take an unsigned long
aligned address (though some architectures are able to handle unaligned
address correctly)
So some 64bit architectures may not be able to access the dqc_bitmap
correctly.
This avoids such unaligned access by using another wrapper functions for
ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to
handle unaligned bitmap access.

With indexed_dir enabled, ocfs2 maintains a list of dirblocks having
space.
The credit calculation in ocfs2_link_credits() did not correctly account
for adding an entry that exactly fills a dirblock that triggers removing
that dirblock by changing the pointer in the previous block in the list.
The credit calculation did not account for that previous block.
To expose, do:
mkfs.ocfs2 -b 512 -M local /dev/sdX
mount /dev/sdX /ocfs2
mkdir /ocfs2/linkdir
touch /ocfs2/linkdir/file1
for i in `seq 1 29` ; do link /ocfs2/linkdir/file1
/ocfs2/linkdir/linklinklinklinklinklink$i; done
rm -f /ocfs2/linkdir/linklinklinklinklinklink10
sleep 8
link /ocfs2/linkdir/file1
/ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Note:
The link names have been crafted for a 512 byte blocksize. Reproducing
with a larger blocksize will require longer (or more) links. The sleep
is important. We want jbd2 to commit the transaction so that the missing
block does not piggy back on account of the previous transaction.

ocfs2: Fix cleancache initialization call to correctly pass uuid
As reported by Steven Whitehouse in https://lkml.org/lkml/2011/5/27/221
the ocfs2 volume UUID is incorrectly passed to cleancache.
As a result, shared-ephemeral tmem pools will not actually
be created; instead they will be private (unshared) which
misses out on a major benefit of tmem.

When we deleting a direntry from a directory, if it's the first in a block we
invalid it by setting inode to 0; otherwise, we merge the deleted one to the
prior and contiguous direntry. And we don't truncate directories.
There is a problem for the later case since inode is not set to 0.
This problem happens when the caller passes a file position as parameter to
ocfs2_dir_foreach_blk(). If the position happens to point to a stale(not
the first, deleted in betweens of ocfs2_dir_foreach_blk()s) direntry, we are
not able to recognize its staleness. So that we treat it as a live one wrongly.
The fix is to set inode to 0 in both cases indicating the direntry is stale.
This won't introduce additional IOs.

ocfs2 implements its own llseek() to provide the SEEK_HOLE/SEEK_DATA
functionality.
SEEK_HOLE sets the file pointer to the start of either a hole or an unwritten
(preallocated) extent, that is greater than or equal to the supplied offset.
SEEK_DATA sets the file pointer to the start of an allocated extent (not
unwritten) that is greater than or equal to the supplied offset.
If the supplied offset is on a desired region, then the file pointer is set
to it. Offsets greater than or equal to the file size return -ENXIO.
Unwritten (preallocated) extents are considered holes because the file system
treats reads to such regions in the same way as it does to holes.

This patch address two shortcomings in ocfs2_page_mkwrite():
1. Makes the function return better VM_FAULT_* errors.
2. It handles a error that is triggered when a page is dropped from the mapping

The cluster up check only checks to see if the node is heartbeating or not.
If yes it continues assuming that the node is connected to all the nodes. But
if that is not the case, the cluster join aborts with a stack of errors that

This patch adds the network connect check upfront and prints the nodes that
the node is not yet connected to, before aborting.

In dlmlock_remote(), we wait for the resource to stop being active before
setting the inprogress flag. Active includes recovery, migration, etc.
The problem here is that if the resource was being recovered or migrated, the
new owner could very well be that node itself (and thus not a remote node).
This problem was observed in Oracle bug#12583620. The error messages observed
were as follows:
dlm_send_remote_lock_request:337 ERROR: Error -40 (ELOOP) when sending message 503 (key 0xd6d8c7) to node 2

The inflight reference count, in the lock resource, is taken to pin the resource
in memory. We take it when a new resource is created and release it after a
lock is attached to it. We do this to prevent the resource from getting purged
prematurely.
Earlier this reference count was being taken for locally mastered resources
only. This patch extends the same functionality for remotely mastered ones.
We are doing this because the same premature purging could occur for remotely
mastered resources if the remote node were to die before completion of the
create lock.
Fix for Oracle bug#12405575.

When someone writes to an inode, readers accessing the same inode via
ocfs2_readpage() just busyloop trying to get ip_alloc_sem because
do_generic_file_read() looks up the page again and retries ->readpage()
when previous attempt failed with AOP_TRUNCATED_PAGE. When there are enough
readers, they can occupy all CPUs and in non-preempt kernel the system is
deadlocked because writer holding ip_alloc_sem is never run to release the
semaphore. Fix the problem by making reader block on ip_alloc_sem to break
the busy loop.

Fix a corruption that can happen when we have (two or more) outstanding
aio's to an overlapping unaligned region. Ext4
(e9e3bcecf44c04b9e6b505fd8e2eb9cea58fb94d) and xfs recently had to fix
similar issues.
In our case what happens is that we can have an outstanding aio on a region
and if a write comes in with some bytes overlapping the original aio we may
decide to read that region into a page before continuing (typically because
of buffered-io fallback). Since we have no ordering guarantees with the
aio, we can read stale or bad data into the page and then write it back out.
If the i/o is page and block aligned, then we avoid this issue as there
won't be any need to read data from disk.
I took the same approach as Eric in the ext4 patch and introduced some
serialization of unaligned async direct i/o. I don't expect this to have an
effect on the most common cases of AIO. Unaligned aio will be slower
though, but that's far more acceptable than data corruption.

The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be
UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a
SWP instruction will cause an oops when the kprobes emulation code
executes an undefined instruction.
As the SWP instruction should be rare or non-existent in kernels for
ARMv6 and later, we can simply avoid these problems by not allowing
probing of these.

There is a kprobes testcase for the instruction "strd r2, [r3], r4".
This has unpredictable behaviour as it uses r3 for register writeback
addressing and also stores it to memory.
On a cortex A9, this testcase would fail because the instruction writes
the updated value of r3 to memory, whereas the kprobes emulation code
writes the original value.
Fix this by changing testcase to used r5 instead of r3.
