The iq80310 mtd map driver depends on ARCH_IQ80310, which isn't
defined anywhere in the tree (as we don't have 80310 support), and
furthermore, everything the driver does can be done with physmap
instead.

We certainly don't need the check for Linux version > 2.5.2, and in fact
we can also live without the __ECOS check, since we can just add it back
in the eCos git tree which is automatically derived from the Linux fs/jffs2
subdirectory in the upstream git tree.

Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is
always locked after power-up, so all sectors need to be unlocked before it
is usable.
If this flag is set, and the chip provides an unlock() operation,
mtd_add_device will unlock the whole MTD device if it's writeable. This
means that non-writeable partitions will stay locked.
Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work
as expected.

Noticed that the U3_*CFA macros have some typos:
#define U3_HT_CFA0(devfn, off) \
((((unsigned long)devfn) << 8) | offset)
(refers to offset rather than off)
#define U3_AGP_CFA0(devfn, off) \
((1 << (unsigned long)PCI_SLOT(dev_fn)) \
| (((unsigned long)PCI_FUNC(dev_fn)) << 8) \
(refers to dev_fn rather than devfn)

When there is a PCI-X mode 2 capable device behind the HT<->PCI-X
bridge, the pci core decides that the device has the extended 4K
config space, even though the bus is not operating in mode 2. This is
because the u3_ht pci ops silently accept offsets greater than 255 but
use only the 8 least significant bits, which means reading at offset
0x100 gets the data at offset 0x0, and causes confusion for lspci.
Reject accesses to configuration space offsets greater than 255.

Ulrich Weigand found a bug with the current version of the
asm-powerpc/ptrace.h that prevents building at least the
SPU target version of gdb, since some ptrace opcodes are
not defined.
The problem seems to have originated in the merging of 32 and
64 bit versions of that file, the problem is that some opcodes
are only valid on 64 bit kernels, but are also used by 32 bit
programs, so they can't depends on the __powerpc64__ symbol.

Fix a bug in the directory reading code, where we might have dereferenced
a NULL pointer in case of OOM. Updated the directory code to use the new
& improved version of gfs2_meta_ra() which now returns the first block
that was being read. Previously it was releasing it requiring following
code to grab the block again at each point it was called.
Also turned off readahead on directory lookups since we are reading a
hash table, and therefore reading the entries in order is very
unlikely. Readahead is still used for all other calls to the
directory reading function (e.g. when growing the hash table).
Removed the DIO_START constant. Everywhere this was used, it was
used to unconditionally start i/o aside from a couple of places, so
I've removed it and made the couple of exceptions to this rule into
separate functions.
Also hunted through the other DIO flags and removed them as arguments
from functions which were always called with the same combination of
arguments.
Updated gfs2_meta_indirect_buffer to be a bit more efficient and
hopefully also be a bit easier to read.

Keep hashed user tokens, with the following changes:
32-bit physical device addresses are mapped directly to user-tokens. No
duplicate maps are allowed, and the addresses are assumed to be outside
of the range 0x10000000 through 0x30000000. The user-token is identical
to the 32-bit physical start-address of the map.
64-bit physical device addressed are mapped to user-tokens in the range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
Other map types, like upcoming TTM maps are mapped to user-tokens in the
range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
Implement hashed map lookups.
