When btrfs discovers the generation number in a btree block is
incorrect, it can loop forever without forcing the RAID
code to try a valid mirror, and without returning EIO.
This changes things to properly kick out the EIO.

GCC version 4.5.1 gives the following warning:
drivers/base/power/runtime.c: In function ‘rpm_check_suspend_allowed’:
drivers/base/power/runtime.c:146:25: warning: comparison between ‘enum dpm_state’ and ‘enum rpm_status’
which seems to be a typo in that dev->power.runtime_status
should be compared instead of dev->power.status.

If you mount -o space_cache, the option will be persistent across mounts, but to
make sure the user knows that they did this, emit a message telling them if they
didn't mount with -o space_cache but the feature is still used.

If something goes wrong with the free space cache we need a way to make sure
it's not loaded on mount and that it's cleared for everybody. When you pass the
clear_cache option it will make it so all block groups are setup to be cleared,
which keeps them from being loaded and then they will be truncated when the
transaction is committed. Thanks,

There are just a few things that need to be fixed in the kernel to support mixed
data+metadata block groups. Mostly we just need to make sure that if we are
using mixed block groups that we continue to allocate mixed block groups as we
need them. Also we need to make sure __find_space_info will find our space info
if we search for DATA or METADATA only. Tested this with xfstests and it works
nicely. Thanks,

With the free space disk caching we can mark the block group as started with the
caching, but we don't have a caching ctl. This can race with anybody else who
tries to get the caching ctl before we cache (this is very hard to do btw). So
instead check to see if cache->caching_ctl is set, and if not return NULL.
Thanks,

This patch actually loads the free space cache if it exists. The only thing
that really changes here is that we need to cache the block group if we're going
to remove an extent from it. Previously we did not do this since the caching
kthread would pick it up. With the on disk cache we don't have this luxury so
we need to make sure we read the on disk cache in first, and then remove the
extent, that way when the extent is unpinned the free space is added to the
block group. This has been tested with all sorts of things.

This is a simple bit, just dump the free space cache out to our preallocated
inode when we're writing out dirty block groups. There are a bunch of changes
in inode.c in order to account for special cases. Mostly when we're doing the
writeout we're holding trans_mutex, so we need to use the nolock transacation
functions. Also we can't do asynchronous completions since the async thread
could be blocked on already completed IO waiting for the transaction lock. This
has been tested with xfstests and btrfs filesystem balance, as well as my ENOSPC
tests. Thanks,

MRSHPC is wholly unused here, no need to trap it specially. If support is
added in the future it can be taken care of via platform data like on the
others.

The only reason this board needs to do PIO trapping is for ethernet,
which happens to follow the same scheme as its bigger brother the
edosk7760. With ethernet properly supported through the platform device,
we can kill off the left over PIO abortion.

The PIO trapping was only for MRSHPC and the SMC ethernet. Given that the
SMC ethernet is already properly handled and that nothing is using the
MRSHPC, none of this is needed.

This code has been untouched since it was merged many years ago, and has
severely bitrotted since, suggesting that the board has no real users
left. Notice of intent to remove has been sent out over the last few
years, with no takers. Kill it off.

None of these PIO routines do anything other than basic error checking,
get rid of them and use the generic fallbacks.

flush_scheduled_work() is deprecated and scheduled to be removed.
sync_stop() currently cancels cpu_buffer works inside buffer_mutex and
flushes the system workqueue outside. Instead, split end_cpu_work()
into two parts - stopping further work enqueues and flushing works -
and do the former inside buffer_mutex and latter outside.

The kernel build with CONFIG_OPROFILE and CPU_HOTPLUG enabled.
The oprofile is initialised using system timer in absence of hardware
counters supports. Oprofile isn't started from userland.
In this setup while doing a CPU offline the kernel hangs in infinite
for loop inside lock_hrtimer_base() function
This happens because as part of oprofile_cpu_notify(, it tries to
stop an hrtimer which was never started. These per-cpu hrtimers
are started when the oprfile is started.
echo 1 > /dev/oprofile/enable
This problem also existwhen the cpu is booted with maxcpus parameter
set. When bringing the remaining cpus online the timers are started
even if oprofile is not yet enabled.
This patch fix this issue by adding a state variable so that
these hrtimer start/stop is only attempted when oprofile is
started
For stable kernels v2.6.35.y and v2.6.36.y.

The microdev only has to contend with silly PIO mangling on anything
within the SuperIO range. As each of the SuperIO modules is already
speciail cased, we just shift that logic over to the ioport map.
With microdev PCI never being merged (and being fudamentally broken in
hardware), and the ethernet chip only doing 16-bit accesses already,
there's no need to maintain any of the extra special casing. Kill it all
off.

nameidata_to_filp() drops nd->path or transfers it to opened
file. In the former case it's a Bad Idea(tm) to do mnt_drop_write()
on nd->path.mnt, since we might race with umount and vfsmount in
question might be gone already.
Fix: don't drop it, then... IOW, have nameidata_to_filp() grab nd->path
in case it transfers it to file and do path_drop() in callers. After
they are through with accessing nd->path...
