commit 9d3a0de makes slaves expire as they would do on the master
with much shorter timeouts. But it introduces another problem:
When we close a connection, on master server the connection became
CLOSE_WAIT/TIME_WAIT, it was synced to slaves, but if master is
finished within it's timeouts (CLOSE), it will not be synced to
slaves. Then slaves will be kept on CLOSE_WAIT/TIME_WAIT until
timeout reaches. Thus we should also sync with CLOSE.

There is not enough users to warrant its existence, and it is actually
an obstacle to progress with the new DMA API which cannot cover this

There's no point having the hardware support background operations
if we issue a cache operation, and then wait for it to complete
before calculating the address of the next operation. We gain no
advantage in the cache controller stalling the bus until completion.
What we should be doing is using the 'wait' time productively by
calculating the address of the next operation, and only then waiting
for the previous operation to complete. This means that cache
operations can occur in parallel with the CPU calculating the next
address.

Add check if APIC is not disabled since thermal
monitoring depends on it. As only apic gets disabled
we should not try to install "thermal monitor" vector,
print out that thermal monitoring is enabled and etc...
Note that "Intel Correct Machine Check Interrupts" already
has such a check.
Also I decided to not add cpu_has_apic check into
mcheck_intel_therm_init since even if it'll call apic_read on
disabled apic -- it's safe here and allow us to save a few code
bytes.

This fixes the following breakage of the commit
75f1cdf1dd:
- GART systems that don't AGP with broken BIOS and more than 4GB
memory are forced to use swiotlb. They can allocate aperture by
hand and use GART.
- GART systems without GAP must disable GART on shutdown.
- swiotlb usage is forced by the boot option,
gart_iommu_hole_init() is not called, so we disable GART
early_gart_iommu_check().

The reason of removal, "replaced by allowdac and no dac
combination" is incorrect. There is no way to do the same thing
with "allowdac" and "nodac" combination.

DAC with this option even if some of VIA bridges seem to be

This was intended to allow manual override of CPU settings copied automatically
to Kconfig.auto, however it's problematic for several reasons, but mostly:
* If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for
that defconfig to iverride the values in the kernel source tree. This leads
to very strange errors where the kernel is compiled with the wrong CPUFLAGS.
Next patch in the series will back out the default in Kconfig.auto to baseline
settings, so a kernel built with no default values will at least boot on any
hardware, just not make use of additional CPU features.
