Use the newly introduced pci_ioremap_bar() function in drivers/usb.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

This patch corrects the issue when one connects a Nokia 5200 cell

The MicroSD card in the phone remains inaccessible and finally the
cell phone turns itself off. The patch solves this problem and makes
the cell phone fully accessible:

I've found necessary to use the FL_US_CAPACITY_FIX switch, as without

low-level functions on it (a fdisk -l /dev/uba for example).

I have another Argosy USB storage device, which has the same problem
with the Argosy USB storage device already fixed in 2.6.27.7. But this
device has another product ID (840:84), so this patch adds a new entry
into unusual_devs to fix the mount problem.
I enclose here two patches: one against 2.6.27.8, and another against
the latest linus-git tree.
The information about the Argosy device is like below:

The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the
no-longer-existant ___swab32() method (three underscores). We got rid
of some of the worst indirection and complexity, and now it should just
use the 32-bit swab function that was defined right above it.

The first step to make swab.h a regular header that will
include an asm/swab.h with arch overrides.
Avoid the gratuitous differences introduced in the new
linux/swab.h by naming the ___constant_swabXX bits and
__fswabXX bits exactly as found in the old implementation
in byteorder/swab[b].h
Use this new swab.h in byteorder/[big|little]_endian.h and
remove the two old swab headers.
Although the inclusion of asm/byteorder.h looks strange in
linux/swab.h, this will allow each arch to move the actual
arch overrides for the swab bits in an asm file and then
the includes can be cleaned up without requiring a flag day
for all arches at once.
Keep providing __fswabXX in case some userspace was using them
directly, but the revised __swabXX should be used instead in
any new code and will always do constant folding not dependent
on the optimization level, which means the __constant versions
can be phased out in-kernel.
Arches that use the old-style arch macros will lose their
optimized versions until they move to the new style, but at
least they will still compile. Many arches have already moved
and the patches to move the remaining arches are trivial.

This avoids a BUG_ON in the enter_vt path due to objects being in the GTT
when we shouldn't have ever let them be (as we're not supposed to touch the
device during that time).
This was triggered by a change in the 2D driver to use the GTT mapping of
objects after pinning them to improve software fallback performance.

Use del_timer_sync() instead of del_timer() to make sure the timer won't
be running when we return from parport_wait_event(), because this would
crash due to destruction of timer_list.
This is untested and just based on a code review. Just think about the
following sequence of events:
- add_timer()
- down_interruptible() is interrupted by a signal.
- we enter the timer callback handler on another CPU.
- del_timer(), but the timer callback is still running.
- eturn from parport_wait_even, which destroys the automatic variable
"timer" while the callback is running on another CPU.

Since all sanity checks rely on the validity of s_start which gets only
checked to be smaller than s_end, we should also check if s_end is sane.
Now we also try to retrieve the last block of the filesystem, which is
computed by s_end. If this fails, something is bogus.

bfs_fill_super() already touches all inodes, so we can easily add some
cheap sanity checks and check if the inode start and end blocks are
smaller than the maximum number of blocks, the inode start block lies
behind the end block or the file end offset is behind the end of the
filesystem. Also check if the start of data offset in the super block
fits the filesystem.
The added sanity checks catch softlockup issues early when we try to
sb_bread() lots of blocks in a loop in bfs_readdir() and bfs_find_entry().
In addition an oom issue in bfs_fill_super() is prevented by this when
s_start is corrupted, which influences imap_len and we try to allocate a
huge info->si_imap.
