  to on state. Without this the devices may not work correctly after

  let's also remove the unusable states.

Signed-off-by: Olof Johansson <olof@lixom.net>

This patch fixes a non-booting issue in Mainline.

When booting with a compressed kernel, we need to be careful how we
populate memory close to DDR start.  AUTO_ZRELADDR is enabled by default
in multi-arch enabled configurations, which place some restrictions on
where the kernel is placed and where it will be uncompressed to on boot.

AUTO_ZRELADDR takes the decompressor code's start address and masks out
the bottom 28 bits to obtain an address to uncompress the kernel to
(thus a load address of 0x42000000 means that the kernel will be
uncompressed to 0x40000000 i.e. DDR START on this platform).

Even changing the load address to after the co-processor's shared memory
won't render a booting platform, since the AUTO_ZRELADDR algorithm still
ensures the kernel is uncompressed into memory shared with the first
co-processor (0x40000000).

Another option would be to move loading to 0x4A000000, since this will
mean the decompressor will decompress the kernel to 0x48000000. However,
this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of
memory would essentially be wasted for no good reason.

Until we can work with ST to find a suitable memory location to
relocate co-processor shared memory, let's disable the shared memory
nodes.  This will ensure a working platform in the mean time.

NB: The more observant of you will notice that we're leaving the DMU
shared memory node enabled; this is because a) it is the only one in
active use at the time of this writing and b) it is not affected by
the current default behaviour which is causing issues.

The isa_bus_init function must be called before drivers which utilize
the ISA bus driver are registered. A race condition for initilization
exists if device_initcall is used (the isa_bus_init callback is placed
in the same initcall level as dependent drivers which use module_init).
This patch ensures that isa_bus_init is called first by utilizing
postcore_initcall in favor of device_initcall.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.

To allow ISA-style drivers on modern systems, this patch introduces the
ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now
build conditionally on the ISA_BUS_API Kconfig option, which defaults to
the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the
ISA_BUS_API Kconfig option to be selected on architectures which do not
enable ISA (e.g. X86_64).

The ISA_BUS Kconfig option is currently only implemented for X86
architectures. Other architectures may have their own ISA_BUS Kconfig
options added as required.

This fixes a problem introduced in commit 2f3165ec
"btrfs: don't force mounts to wait for cleaner_kthread to delete one or more subvolumes".

open_ctree eventually calls btrfs_replay_log which in turn calls
btrfs_commit_super which tries to lock the cleaner_mutex, causing a
recursive mutex deadlock during mount.

Instead of playing whack-a-mole trying to keep up with all the
functions that may want to lock cleaner_mutex, put all the cleaner_mutex
lockers back where they were, and attack the problem more directly:
keep cleaner_kthread asleep until the filesystem is mounted.

When filesystems are mounted read-only and later remounted read-write,
open_ctree did not set fs_info->open and neither does anything else.
Set this flag in btrfs_remount so that neither btrfs_delete_unused_bgs
nor cleaner_kthread get confused by the common case of "/" filesystem
read-only mount followed by read-write remount.

This is just a screwup for developers, so change it to an ASSERT() so developers
notice when things go wrong and deal with the error appropriately if ASSERT()
isn't enabled.  Thanks,
