speedtouch: remove some redundant casts.

This is the mysterious masked patch I just sent, but with a name this time.

  speedtouch: get rid of the global minor_data array.  This means that there is now no
  limit to the number of devices that can be handled by the driver.

  speedtouch: remove the kernel thread and all the junk that went with it.
  The work it did can all be done in interrupt context, so use a tasklet instead.

[PATCH] USB visor: Split up the initialization command logic to handle different device types better.

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.

vm86() direct return code updated to match [ Linus ]

This also cleans up the machine check code generally.

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.

- Merged AES code from Adam J. Richter <adam@yggdrasil.com>
- Add kconfig help and test vector code from
  Martin Clausen <martin@ostenfeld.dk>
- Minor cleanups: removed EXPORT_NO_SYMBOLS (not needed for 2.5),
  removed debugging code etc.
- Documentation updates.

Since we killed off the broken 486 strings copies,
the config item isn't needed any longer.
