The commit f4780ca005404166cc40af77ef0e86132ab98a81 moves
swiotlb initialization before dma32_free_bootmem(). It's
supposed to fix a bug that the commit
75f1cdf1dda92cae037ec848ae63690d91913eac introduced, we
initialize SWIOTLB right after dma32_free_bootmem so we wrongly
steal memory area allocated for GART with broken BIOS earlier.
However, the above commit introduced another problem, which
likely breaks machines with huge amount of memory. Such a box
use the majority of DMA32_ZONE so there is no memory for
swiotlb.
With this patch, the x86 IOMMU initialization sequence are:
1. We set swiotlb to 1 in the case of (max_pfn > MAX_DMA32_PFN
&& !no_iommu). If swiotlb usage is forced by the boot option,
we go to the step 3 and finish (we don't try to detect IOMMUs).
2. We call the detection functions of all the IOMMUs. The
detection function sets x86_init.iommu.iommu_init to the IOMMU
initialization function (so we can avoid calling the
initialization functions of all the IOMMUs needlessly).
3. We initialize swiotlb (and set dma_ops to swiotlb_dma_ops) if
swiotlb is set to 1.
4. If the IOMMU initialization function doesn't need swiotlb
(e.g. the initialization is sucessful) then sets swiotlb to zero.
5. If we find that swiotlb is set to zero, we free swiotlb
resource.

This adds a new category of symbols to the relocs program: symbols
which are known to be relative, even though the linker emits them as
absolute; this is the case for symbols that live in the linker script,
which currently applies to _end.
Unfortunately the previous workaround of putting _end in its own empty
section was defeated by newer binutils, which remove empty sections
completely.
This patch also changes the symbol matching to use regular expressions
instead of hardcoded C for specific patterns.
This is a decidedly non-minimal patch: a modified version of the
relocs program is used as part of the Syslinux build, and this is
basically a backport to Linux of some of those changes; they have
thus been well tested.

The MSR driver would compute the values for cpu and c at declaration,
and then again in the body of the function. This isn't merely
redundant, but unsafe, since cpu might not refer to a valid CPU at
that point.
Remove the unnecessary and dangerous references in the declarations.
This code now matches the equivalent code in the CPUID driver.

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
75f1cdf1dda92cae037ec848ae63690d91913eac:
- 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().

When there are a large number of processors in a system, there
is an excessive amount of messages sent to the system console.
It's estimated that with 4096 processors in a system, and the
console baudrate set to 56K, the startup messages will take
about 84 minutes to clear the serial port.
This set of patches limits the number of repetitious messages
which contain no additional information. Much of this information
is obtainable from the /proc and /sysfs. Some of the messages
are also sent to the kernel log buffer as KERN_DEBUG messages so
dmesg can be used to examine more closely any details specific to
a problem.
The new cpu bootup sequence for system_state == SYSTEM_BOOTING:
Booting Node 0, Processors #1 #2 #3 #4 #5 #6 #7 Ok.
Booting Node 1, Processors #8 #9 #10 #11 #12 #13 #14 #15 Ok.
...
Booting Node 3, Processors #56 #57 #58 #59 #60 #61 #62 #63 Ok.
Brought up 64 CPUs
After the system is running, a single line boot message is displayed
when CPU's are hotplugged on:
Booting Node %d Processor %d APIC 0x%x
Status of the following lines:
CPU: Physical Processor ID: printed once (for boot cpu)
CPU: Processor Core ID: printed once (for boot cpu)
CPU: Hyper-Threading is disabled printed once (for boot cpu)
CPU: Thermal monitoring enabled printed once (for boot cpu)
CPU %d/0x%x -> Node %d: removed

The current rd/wrmsr_on_cpus helpers assume that the supplied
cpumasks are contiguous. However, there are machines out there
like some K8 multinode Opterons which have a non-contiguous core
enumeration on each node (e.g. cores 0,2 on node 0 instead of 0,1), see
http://www.gossamer-threads.com/lists/linux/kernel/1160268.
This patch fixes out-of-bounds writes (see URL above) by adding per-CPU
msr structs which are used on the respective cores.
Additionally, two helpers, msrs_{alloc,free}, are provided for use by
the callers of the MSR accessors.

Jens found the following crash/regression:
[ 0.000000] found SMP MP-table at [ffff8800000fdd80] fdd80
[ 0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 0-fff BIOS data page
and
[ 0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 6000-7fff TRAMPOLINE
and bisected it to b24c2a9 ("x86: Move find_smp_config()
earlier and avoid bootmem usage").
It turns out the BIOS is using the first 64k for mptable,
without reserving it.
So try to find good range for the real-mode trampoline instead of
hard coding it, in case some bios tries to use that range for sth.

The per_cpu cpuid4_info shared_map can contain stale data when CPUs are added
and removed.
The stale data can lead to a NULL pointer derefernce panic on a remove of a
CPU that has had siblings previously removed.
This patch resolves the panic by verifying a cpu is actually online before
adding it to the shared_cpu_map, only examining cpus that are part of
the same lower level cache, and by updating other siblings lowest level cache
maps when a cpu is added.

The data structure changes to use dev->archdata.iommu field
broke the iommu=pt mode because in this case the

set_iopl_mask() is a no-op on 64 bits, but it is also a paravirt hook,
so call it even on 64 bits.

In the PTREGSCALL1 and 2 macros, we can trivially avoid an unnecessary
pipeline serialization, so do so.
In PTREGSCALLS3 this is much less clear-cut since we have to push a
new value to the stack. Leave it alone for now assuming it is as good
as it is going to be; may want to check on Atom or another in-order
x86 to see if we can do better.

Add new stubs which add the pt_regs pointer as the last arg, matching
64-bit. This will allow these syscalls to be easily merged.
