Display the total slab memory in /proc/meminfo.  Handy while we play
with the slab pruning code.

This info is also available via /proc/slabinfo, but I think this
convenience is worth the extra few lines.

Patch from Christoph Hellwig.

Move the buffer_head-based IO functions out of ll_rw_blk.c and into
fs/buffer.c.  So the buffer IO functions are all in buffer.c, and
ll_rw_blk.c knows nothing about buffer_heads.

This patch has been acked by Jens.

From Anton Altaparmakov

The below bk patch against your current bk repository adds an export
for fs/buffer.c::unmap_underlying_metadata() to modules.

It is required to make ntfs compile as a module in the current kernel.

Note that NTFS doesn't currently dirty bufferheads of the underlying
blockdevice and as such could probably live without calling
unmap_underlying_metadata() but as soon as we enable writing to
compressed files it will do so and considering some of the
infrastructure code is already present I would rather not rip it out
now.

Patch by Christoph Hellwig.

This patch is cleanup of mmap.c with the side-effect of making the lock
order of mapping->i_shared_lock and mm->page_table_lock consistant.

__remove_shared_vm_struct is merged into its only caller,
remove_shared_vm_struct, which now also does the job of
{lock,unlock}_vma_mappings itself, to avoid duplicate checks.

Similarly, vma_link is updated to take and release i_shared_lock
itself, fixing the lock order.  split_vma is updated to use
insert_vm_struct instead of using __insert_vm_struct and taking
page_table_lock and i_shared_lock itself (wrongly).  __insert_vm_struct
is removed as it is unused now.

Patch from Christoph Hellwig.  250 lines of code go away.

The three syscalls madvice/mlock/mprotect all change attributes of
memory regions.  These attributes are stored in vm_area_structs (VMAs).

The current code for those syscalls does this by having four
subroutines each, for changing a whole VMA, one for just setting new
flags if a full VMA is affected, one that creates a new VMA in the
right part of the old one and sets the flags there, one for the left
part, and one that splits of both the left and the right part and sets
the new flags in the middle.

This patch makes those routines create new VMAs on the left and on te
right hand first and then always setting the flags in the old VMA.
Together with using a library function (split_vma) to to the split this
simplies the code and makes it more readable.  As a side affect it
fixes some VM accounting bugs observed by Hugh Dickins.

Patch from Christoph Hellwig moves the madvise implementation out of
filemap.c and into its own .c file.  No other changes are made.

Andrew removed a flush_dcache_page in his kmap_atomic generic_file_*
changes.

Doing that sort of corrupts data on some platforms.

Now that all archs use the same way to generate the link script, we can
handle it from the common top-level Makefile instead of the individual
arch/*/Makefile's.

Untested, but at least it should show how to adapt the mips arch.

Untested, but at least it should show how to adapt the cris arch.

This is an untested attempt to convert ARM to preprocessing vmlinux.lds.S
instead of running sed on it - This probably allows for further cleanup,
but I'll leave that to _rmk_.

For consistency reasons, generate 

	arch/$(ARCH)/vmlinux.lds.s

from 

 	arch/$(ARCH)/vmlinux.lds.S

on all archs, even those which do not need preprocessing (yet).

Sam Ravnborg:

Yep, "if_changed_dep" uses fixdep, so a dependency to scripts is needed.
Added echo_target as well, so the result file is printed as well.

remove unused pdc202xx.h

but makes it impossible to shut down cleanly.

Renames console.c and vt.c. The idea is to break these massive files into smaller ones. The main goal is to move all the high end tterminal emulation into one file. This way we can have a light weight printk without the extra weight. nice for embedded systems.

Removed selection.h header. It is not needed and in the future selections will be a pure userland solution. Use set_current_state instead in tty_ioctl.c.
