This allows drivers to pass their struct device through to
tty_register_device, which in turn allows sysfs to show which
device and driver owns the UART.

8250.c should be using the replacement UPIO_xxx macros instead.

Patch from Ben Dooks

Serial driver for S3C2410 on board UARTs. Re-post of 1796/1

Includes BAST driver to register on-board 16550s.

We default to "long" (which is what POSIX says), but since
a number of architectures have used "int" for historical
reasons, we need to allow overrides.

At least sparc64 needs this. Possibly others, but so far
architecture maintainers haven't spoken up. ppc64 and x86-64
are known to be ok with the default "long".

Patch fixes the build for PPC40x platforms.

From: Tom Rini <trini@kernel.crashing.org>

When I was updating ppc/boot/simple/relocate.S to work on PPC_PREP systems, I
in advertantly broke 4xx systems.  On classic PPC, the first three
instructions are nops, of which the first two can be overwritten.  This is
not true of 4xx (or 8xx, but that's not working right now anyhow).  The
following is needed to fix this.

The commoncap module calls this.

- Use -march=armv6 where available.
- CFLAGS_BOOT isn't needed - the decompressor uses CFLAGS, remove it.
- PROCESSOR is never used, remove it.
- LDFLAGS_BLOB is never used, remove it.
- Remove MACHINE macro.
- Correct comments for include/asm-arm/.arch target.
- Copy format of include/asm symlink rule.
- Arrange for configuration to be split before making
  include/asm-arm/arch symlink.
- This means that asm-offsets.s no longer depends on
  include/config/MARKER.

diva_os_cancel_soft_isr() may not call tasklet_kill(), because it is
interrupt context.  This will be done correctly in the cleanup function
anyway.

The patch to check "maxcpus=N" early broke by putting maxcpus (a
variable which is only exported by mpparse.c) into
parse_cmdline_early().

The fix is to make it depend on the correct CONFIG_ option. 

In the subarchitectures:

CONFIG_X86_SMP is the one that means "I want standard x86 smp code" and
that's what this should depend on.

This patch from Christoph Hellwig does much welcomes cleanup of
the old mac53c94 and mesh SCSI drivers, removing sillycaps etc...

Fix this:

 	  Building modules, stage 2.
 	  MODPOST
 	LANG := en_US.UTF-8
 	make: LANG: Command not found
 	make: *** [all] Error 127

by removing the tab in front of the LANG assignment.

This fixes a problem in sys_swapon that can cause the creation of invalid
swap ptes.  This has its cause in the arch-independent swap entries vs. 
the pte coded swap entries.  The swp_entry_t uses 27 bits for the offset
and 5 bits for the type.  In sys_swapon this definition is used to find how
many swap devices and how many pages on each device there can be.  But the
swap entries encoded in a pte can be subject to additional restrictions due
to the hardware besides the 27/5 division of the bits in the swp_entry_t
type.  This is solved by adding pte_to_swp_entry and swp_entry_to_pte calls
to the calculations for maximum type and offset.

In addition the s390 swap pte division for offset/type is changed from 19/6
bits to 20/5 bits.

Seven callsites and an out-of-line copy is a bit excessive.  562 bytes saved.

Display number of slab, mapped and pagetable pages in the sysrq-M output.

If someone runs page_address() before page_address_init(), the kernel locks
up over uninitialised spinlocks.

This only happens with the 4:4 patch, but it is more robust to run
page_address_init() before setup_arch().  page_address_init() simply
initialises statically allocated storage.
