Remove the pci_dma functionality from the Acorn SCSI drivers, and
replace with the new DMA API, passing in the generic struct device.

Add 00-INDEX and booting documentation, remove obsolete DMA
documentation.

cpu-sa11x0: CPUFREQ_ALL_CPUS shouldn't be passed as argument to
cpufreq_notify_transition() any more, but the exact CPU number.

mach-integrator: cpufreq_notify_transition() isn't called -- which
means that the transition notifiers are not informed. This patch adds
these callbacks. Also, CPUFREQ_ALL_CPUS can't passed to
cpufreq_driver->set_policy any longer, so some code can safely be
removed.

This fixes the ARM __put_user implementation.  The gcc folk have
agreed that the %Qn and %Rn register notation in asm() statements
should become official, and have been in all compilers which can
be used to build the ARM kernel.

In addition, we remove some historical gunk from when put_user()
and get_user() was inlined on ARM.

The old consistent memory allocator, which sat behind
dma_coherent_alloc() and pci_consistent_alloc() was completely unable
to handle allocations from interrupt context because we traditionally
used ioremap, which in turn:
  - allocates memory using GFP_KERNEL for the vm_struct
    and the page tables themselves.
  - calls get_vm_area, which uses write_lock, and therefore
    is unsafe to call from interrupt context.

In order to address this issue, a new consistent_alloc() which avoids
the above issues has been implemented.  Essentially, we set aside
a section of the kernel VM space, and pre-allocate page tables to
cover this area.  We allocate "consistent" memory within this region.

The handling of the allocation is designed to be generic; it should
be possible to replace the vmalloc(), ioremap() and module_alloc()
without too much hastle, but that would clearly be a 2.7 thing at
this stage.

This brings sa1100fb up to date with 2.5.54.

The CPU ID no longer contains sufficient information to reliably
determine the manufacturer of a specific part.  To prevent #ifdef
madness appearing in the per-CPU support files, it is better to
remove the CPU manufacturer string entirely.

This patch, which depends on the previous %ebx -> %ebp patch, removes
all pop instruction in the sysenter return path.

This leaks the thread_info address to user mode but this shouldn't be
a security problem.

This is what happens to the various registers:

	%eax: return value from system call: already in place
	%ebx, %esi, %edi: saved by the C compiler
	%ecx, %edx, %ebp: restored by user mode, fixed values by kernels
	%esp, eip: copied to %ecx/%edx and restored by sysexit
	%ds, %es: initialized to __USER_DS on kernel entry
	%cs, %ss: restored by sysexit based on msr
	%fs, %gs: not modified by the kernel (saved around context switch)
	eflags: not preserved, iopl saved around context switch
	FP, XMM: any code that modifies them must save/restore them

Note that while it is possible to change %ebx, %esi, %edi, %ecx, %edx
or %ebp via struct pt_regs, anything that does should set TIF_IRET or
another work flag (and it hopefully already does).

This patch changes assembly code that accesses thread_info to use %ebp
rather than %ebx.

This allows me to take advantage of the fact that %ebp is restored by
user mode in the sysenter register pop removal patch.

Supply the old termios, along with the max and min acceptable baud
rate to uart_get_baud_rate().  uart_get_baud_rate() will now try to
find a baud rate that satisfies the max and min constraint out of
(requested rate, old rate, 9600 baud).

We remove the code which performed a similar act in uart_get_divisor()
and pass an appropriate min and max baud rate to uart_get_baud_rate()
based on the UART clock rate.
