This change alters the behavior of the "MCP10x Store Gathering
Enable" option.  Previously, selecting this option would enable
store gathering, while not selecting the option would leave the
firmware-provided state. In short, there was no way to disable
store gathering if the firmware had left it enabled. This caused
problems with the Adaptec 2940U2W when run in 8240 and 8245
Sandpoint systems. The new code will disable store gathering unless
the user requests it.

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.

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.

Next in line for the -W cleanups is this patch from Willy
which I've been carrying since 2.5.29 or so. Should be no
functional differences, just no more warnings when we compile
with -W

s/boundry/boundary/

Without this fix, compiling with CONFIG_DEBUG_SPINLOCK
dies with an unknown variable error..

This looks extremely suspect to me, and seems like
it will prefetch past the end of the pmd, which is a no no.
