Since the BIO-layer assumes that blocks can be merged virtually
at the granularity of BIO_VMERGE_BOUNDARY, independent of what device
is in use, we always need to go through the I/O MMU, even for 64-bit
devices.  Hopefully, the BIO-layer can be made smarter some day.

Add support for the mm->free_area_cache so that we do not stupidly
search from TASK_UNMAPPED_BASE every time we need to allocate some
virtual memory.

Single Unix Specification says:
[ENOMEM] MAP_FIXED was specified, and the range [addr, addr + len) exceeds
that allowed for the address space of a process.

Therefore if addr + len > IA32_PAGE_OFFSET, we should return ENOMEM.

Native IA-32 returns EINVAL on a unmap of size 0. Our behavior is currently
not compatible.

... and also fix the embarrassing bug where NFTL and INFTL will
barf and exit if the add_mtd_blktrans_dev() function _exists_,
rather than actually calling it and barfing if it returns non-zero :)

	compiler warning in perfmon.c.

	this variable will be removed eventually and then irq_descp()
	can be renamed to irq_desc() again.  But for now, this makes it

No need to explicitly zero out global variables.

Jeff Garzik points out the initializing the exit completion at
exit time is foolish: we should just initialize it at creation time
live everything else in that structure, and avoid the memory barrier.

This makes NBD work with the new linux 2.5 block layer design.
Specifically, it fixes memory corruption that results from module
removal and possible memory corruption from sending or receiving disk
data from the server.

It essentially rolls together the changes from two of the last patchlets
that I emailed: the fix for module removal & the fix for incorrect
struct bio usage.  I believe it's wisest to roll these both together
into this one patch since they both deal with making NBD work better
with the 2.5 linux block layer design and without either of which, it's
possible that NBD will corrupt memory.

Other changes I'd like to see introduced (like in the earlier jumbo
patch) meanwhile are feature enhancements so they can wait.  This patch
also should address all the very helpful concerns that have been raised
so far.  Particularly:

1. that the very first submitted NBD patch was broken down [Andrew]
2. that only 1 spinlock is used for all the NBD request_queue structures
   used [Jens,Al]
3. that kmap() is used in case of highmem pages [Jens]
4. that the allocation of request_queue is dynamic and seperate from
   other allocated objects [Al]

This does the following:
 - remove trailing spaces
 - make loop.h independent by including bio.h, blk.h, spinlock.h
 - replace the lock/unlock functions by module_get/module_put;
   in struct loop this is the change
	-       void (*lock)(struct loop_device *);
	-       void (*unlock)(struct loop_device *);
	+       struct module *owner;
 - replace the integer lo_encrypt_type by the pointer lo_encryption;
   there was a race with loop_unregister_transfer
 - fixed an off-by-one in loop_register_transfer

This is Step 1 of a series of half a dozen or so.

Half of the above is from Jari. Anything that is wrong is mine.

There are some bad compiler issues with section confusion ("const" stuff
likes going into the rodata section).

This corrects the back off count so that write errors will not be
ignored

This patch:
- re-enables cumana partition parsing
- adds eesox partition parsing
- makes the powertec partition parsing fail if sector 0 looks like
  a PC bios partition table

Rather than having a single "acorn_partition" parser for all these
types, we list them explicitly in check.c instead, along with some
explaination about why they're where they are.

cifs_statfs() is called with a pointer to a struct kstatfs, so let's
propagate this type into the helper function.

Fix a couple of compilation errors in the mouse code.

It was using a non-existent socket[] index and not doing it for all
sockets.
