Fixed trivial conflicts in drivers/gpu/vga/Kconfig

This makes sure that we pick the synchronous signals caused by a
processor fault over any pending regular asynchronous signals sent to
use by [t]kill().

This is not strictly required semantics, but it makes it _much_ easier
for programs like Wine that expect to find the fault information in the
signal stack.

Without this, if a non-synchronous signal gets picked first, the delayed
asynchronous signal will have its signal context pointing to the new
signal invocation, rather than the instruction that caused the SIGSEGV
or SIGBUS in the first place.

This is not all that pretty, and we're discussing making the synchronous
signals more explicit rather than have these kinds of implicit
preferences of SIGSEGV and friends.  See for example

	http://bugzilla.kernel.org/show_bug.cgi?id=15395

for some of the discussion.  But in the meantime this is a simple and
fairly straightforward work-around, and the whole

	if (x & Y)
		x &= Y;

thing can be compiled into (and gcc does do it) just three instructions:

	movq    %rdx, %rax
	andl    $Y, %eax
	cmovne  %rax, %rdx

so it is at least a simple solution to a subtle issue.

qcaux: add driver for QCDM-capable ports on various devices

Many Qualcomm-based devices provide a CDC-ACM port which accepts
normal AT commands and PPP connections.  But they only provide one
which makes status or signal strength requests impossible while
PPP is active.  They also provide secondary USB interfaces that
talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be
used for status and strength.  Make those QCDM ports accessible.

I've got a trivial patch for the pl2303 driver, that's what I needed to
make the wacom serial tablet driver work properly. It uses the

not, which I gather is rather common, but the pl2303 driver didn't
implement that ioctl.

again.

If no break occurred, the index equals config->desc.bNumInterfaces. A

config->interface[config->desc.bNumInterfaces] at label reset_old_alts.
