jffs2_write_end() is sometimes passing back a "written" length greater
than the length we passed into it, leading to a BUG at mm/filemap.c:1749
when used with unionfs.
It happens because we actually write more than was requested, to reduce
log fragmentation. These "longer" writes are fine, but they shouldn't
get propagated back to the vm/vfs.

Add read_buf/write_buf for s3c2440, which can read/write 32 bits at a
time rather than just 8. In my testing on an s3c2440a running at 400 MHz
with a 100 MHz HCLK, read performance improves by 36% (from 5.19 MB/s
to 7.07 MB/s).

[In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem
with standard permissions on newly-created inodes, when POSIX ACLs are
enabled. This cleans it up...]
The attached patch separate jffs2_init_acl() into two parts.
The one is jffs2_init_acl_pre() called from jffs2_new_inode().
It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL
objects associated with the new inode just before when inode meta
infomation is written to the medium.
The other is jffs2_init_acl_post() called from jffs2_symlink(),
jffs2_mkdir(), jffs2_mknod() and jffs2_do_create().
It actually writes in-memory ACL objects into the medium next to
the success of writing meta-information.
In the current implementation, we have to write a same inode meta
infomation twice when inode->i_mode is updated by the default ACL.
However, we can avoid the behavior by putting an updated i_mode
before it is written at first, as jffs2_init_acl_pre() doing.

This reverts commit a5bf3d891a6a0fb5aa122792d965e3774108b923.
David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.
Because this is a consolidation of a couple old missed patches, it touches both
