Hypervisor interfaces need to be negotiated in order to use
some API calls reliably. So add a small set of interfaces
to request API versions and query current settings.
This allows us to fix some bugs in the hypervisor console:
1) If we can negotiate API group CORE of at least major 1
minor 1 we can use con_read and con_write which can improve
console performance quite a bit.
2) When we do a console write request, we should hold the
spinlock around the whole request, not a byte at a time.
What would happen is that it's easy for output from
different cpus to get mixed with each other.
3) Use consistent udelay() based polling, udelay(1) each
loop with a limit of 1000 polls to handle stuck hypervisor
console.

Building with GCC 4.2, I get the following error:
CC arch/ia64/kernel/mca.o
arch/ia64/kernel/mca.c:275: error: __ksymtab_ia64_mlogbuf_finish causes a
section type conflict
This is because ia64_mlogbuf_finish is both declared static and exported.
Fix by removing the export (which is unneeded now).

The current implementation of kdump on INIT events would enter
kdump processing on DIE_INIT_MONARCH_ENTER and DIE_INIT_SLAVE_ENTER
events. Thus, the monarch cpu would go ahead and boot up the kdump
On SN shub2 systems, this out-of-sync situation causes some slave
cpus on different nodes to enter POD.
This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and
DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in
the DIE_INIT_MONARCH_PROCESS event to not dump all active stack
traces to the console in the case of kdump.
I have tested this patch on an SN machine and a HP RX2600.

This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53.
Andi Kleen is unhappy with the changes, and they really do not seem
worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.
Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.

When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to
deduce the available frequency multipliers from the _PSS tables.
Upon frequency change, processor_perflib performs some verification on the
frequency (checks that it's within allowable bounds).
powernow-k7 deals with absolute frequencies in KHz, whereas perflib only
deals with MHz values. When performing the above verification, perflib
multiplies the MHz values by 1000 to obtain the KHz value.
We then end up with situations like the following:
- powernow-k7 multiplies the multiplier by the FSB, and obtains a value
such as 1266768 KHz
- perflib belives the same state has frequency of 1266 MHz
- acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify
that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000)
- it's not, so that frequency is rejected
- the maximum CPU frequency is not reachable
This patch solves the problem by rounding up the MHz values stored in perflib's
tables. Additionally it corrects a broken URL.
It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this
case is a bit different: the frequencies in the _PSS tables are wildly wrong,
but we get better results if we force ACPI to respect the fsb * multiplier
calculations (even though it seems that the multiplier values aren't entirely
correct either).

SLUB cannot run on i386 at this point because i386 uses the page->private and
page->index field of slab pages for the pgd cache.
Make SLUB run on i386 by replacing the pgd slab cache with a quicklist.
Limit the changes as much as possible. Leave the improvised linked list in place
etc etc. This has been working here for a couple of weeks now.
