This lifts the code diddling the TF and DF bits for signal handler setup
out of the several places copying the same code into the one place that

I also separated the recently-added DF bit clearing from the TF diddling.
The compiler turns them back into one instruction anyway.  The tossing

arcane than seems wise.

f7f17a67c5 x86: remove NexGen support
It is claimed that NexGen CPUs were never shipped:

   http://lkml.org/lkml/2008/4/20/179

Also, the kernel support for these chips has been broken for
a long time, the code intended to support NexGen thereby being
essentially dead.

As an outcome of the discussion that can be found using the URL
above, this patch removes the NexGen support altogether.

The changes in this patch survived a defconfig build for i386, a
couple of successful randconfig builds, as well as a runtime test,
which consisted in booting a 32-bit x86 box up to the shell prompt.

911f6a7ba2 x86-64: extend MCE CPU quirk handling
At least on my Barcelona, I see MCE log entries after cold boot caused
by BIOS not properly clearing the respective registers. Therefore, this
patch extends the workaround to families 0x10 and 0x11 (the latter just
for completeness, I have nothing to verify this against).
At the same time, provide a way to make these entries visible via the
'mce=bootlog' command line option even on these machines.

86d78f6402 x86: fix watchdog ops for CoreDuo
There apparently was an unnoticed conflict between an earlier patch to
this file and mine (d1e084746b), which
I noticed only now. I suppose a change like the one below (untested) is
needed; I didn't get any response on a confirmation request for this from
the submitter of the first patch.

The issue is the writing of the 'checkbit' member at the end of
setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops
rather than wd_ops.

b33d24c4cc V4L/DVB (7750): au0828/ cleanups and fixes
This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
  renamed it to "au0828_debug"
  this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
  already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static

b9ef6bbbbe V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug enabled
set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't
reported.

This patch changed set_addr printk to print a message only if set_addr is
wrong.

It also fix printk at set_type, since, if an attach were failing, nothing
were reported.

With the current code, working or not, a call to set_addr will produce a debug
printk.

also, set_type() were producing a false error message on tuner_xc2028, since
it were requesting for setting a frequency on a place where firmware name
weren't set yet.
