Support for Core CPUs was broken in two ways in speedstep-lib: for x86_64,
we missed a MSR definition; for both x86_64 and i386, the FSB calculation
was wrong by four (it's a quad-pumped bus). Also increase the accuracy
of the calculation.

Fix the bug in duplicate states elimination in acpi-cpufreq.

Bug: Due to duplicate state elimiation in the loop earlier, the number
of valid_states can be less than perf->state_count, in which case
freq_table was ending up with some garbage/uninitialized entries
in the table.

On some systems there could be bits set in the upper half of
the control value provided by the _PSS object.  These bits are
only relevant for cpufreq drivers that use IO ports which are not
currently supported by the speedstep-centrino driver.  The current
MSR oriented code assumes that upper bits are not set and thus
fails to work correctly when they are.  e.g. the control and status
value equality check failed on the IBM x3650 even though the ACPI
spec allows inequality.

seqlock_init() needs to use spin_lock_init() for dynamic locks, so that
lockdep is notified about the presence of a new lock.

(this is a fallout of the recent networking merge, which started using
the so-far unused seqlock_init() API.)

This fix solves the following lockdep-internal warning on current -git:

While working on bidi support at struct request level
I have found that blk_queue_activity_fn is actually never used.
The only user is in ide-probe.c with this code:

	/* enable led activity for disk drives only */
	if (drive->media == ide_disk && hwif->led_act)
		blk_queue_activity_fn(q, hwif->led_act, drive);

And led_act is never initialized anywhere.
(Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18)
Unless it is all for future use off course.

This patch makes paging_init() use highend_pfn/highstart_pfn globals.

It removes the need of 'high' local which was needed only by HIGHMEM config.

More important perhaps, it fixes a bug when HIGHMEM is set but there's
actually no physical highmem (highend_pfn = 0)

While the recent cset 86384d54 did improve
things it didn't resolve all the problems.  So bite the bullet and discard
.exit.text and .exit.data at runtime.  Which of course sucks because it
bloats binaries with code that will never ever be used but it's the only
thing that will work reliable as demonstrated by the function sd_major() in
drivers/scsi/sd.c.

Gcc may compile sd_major() using a jump table which it will put into
.rodata.  If it also inlines sd_major's function body into exit_sd() which
gcc > 3.4.x does.  If CONFIG_BLK_DEV_SD has been set to y we would like ld
to discard exit_sd's code at link time.  However sd_major happens to
contain a switch statement which gcc will compile using a jump table in
.rodata on the architectures I checked.  So, when ld later discards
.exit.text only the jump table in .rodata with its stale references to
the discard .exit.text will be left which any no antique ld will honor
with a link error.

  Normally networking isn't invoked with interrupts turned off, but I
  suppose we don't have a choice here.  This is unique being a place where you
  can get called with BH on, off, or IRQs off.

  Given that this is only used for printk, the easiest solution is probably
  just to disable local IRQs instead of BH.
