Impact: on SGI UV platforms, fix boot crash
UV initialization is currently called too late to call alloc_bootmem_pages().
The current sequence is:
start_kernel()
mem_init()
free_all_bootmem() <--- discard of bootmem
rest_init()
kernel_init()
smp_prepare_cpus()
native_smp_prepare_cpus()
uv_system_init() <--- uses alloc_bootmem_pages()
It should be calling kmalloc().

Impact: fix guest kernel boot crash on certain configs
Recent i686 2.6.27 kernels with a certain amount of memory (between
736 and 855MB) have a problem booting under a hypervisor that supports
batched mprotect (this includes the RHEL-5 Xen hypervisor as well as
any 3.3 or later Xen hypervisor).
The problem ends up being that xen_ptep_modify_prot_commit() is using
virt_to_machine to calculate which pfn to update. However, this only
works for pages that are in the p2m list, and the pages coming from
change_pte_range() in mm/mprotect.c are kmap_atomic pages. Because of
this, we can run into the situation where the lookup in the p2m table
returns an INVALID_MFN, which we then try to pass to the hypervisor,
which then (correctly) denies the request to a totally bogus pfn.
The right thing to do is to use arbitrary_virt_to_machine, so that we
can be sure we are modifying the right pfn. This unfortunately
introduces a performance penalty because of a full page-table-walk,
but we can avoid that penalty for pages in the p2m list by checking if
virt_addr_valid is true, and if so, just doing the lookup in the p2m
table.
The attached patch implements this, and allows my 2.6.27 i686 based
guest with 768MB of memory to boot on a RHEL-5 hypervisor again.
Thanks to Jeremy for the suggestions about how to fix this particular
issue.

This is harmless, because the .acpi_madt_oem_check is only called

Impact: fix missing CPUs in /proc/cpuinfo after CPU hotunplug/hotreplug
In my test, I found that if a cpu has been offline,
the next cpus may not be shown in the /proc/cpuinfo.
if one read() cannot consume the whole /proc/cpuinfo,
c_start() will be called again in the next read() calls.
And *pos has been increased by 1 by the caller(seq_read()).
if this time the cpu#*pos is offline, c_start() will return
NULL, and the next cpus can not be shown.
this fix use next_cpu_nr(*pos - 1, cpu_online_map) to
search the next unshown cpu.
the most easy way to reproduce this bug:
1) offline cpu#1 (cpu#0 is online)
2) dd ibs=2 if=/proc/cpuinfo
the result is that only cpu#0 is shown.
cpu#2 and cpu#3 .... cannot be shown in /proc/cpuinfo
it's bug.

Impact: make warning message disappear - functionality unchanged
Problems with bogus IRQ0 override of those laptops should be fixed
with commits
x86: SB600: skip IRQ0 override if it is not routed to INT2 of IOAPIC
x86: SB450: skip IRQ0 override if it is not routed to INT2 of IOAPIC
that introduce early-quirks based on chipset configuration.
For further information, see
http://bugzilla.kernel.org/show_bug.cgi?id=11516
Instead of removing the related dmi-quirks completely we'd like to
keep them for (at least) one kernel version -- to double-check whether
the early-quirks really took effect. But the dmi-quirks need to be
called after early-quirks are executed. With this patch calling
sequence for dmi-quriks is changed as follows:
acpi_boot_table_init() (dmi-quirks)
...
early_quirks() (detect bogus IRQ0 override)
...
acpi_boot_init() (late dmi-quirks and setup IO APIC)
Note: Plan is to remove the "late dmi-quirks" with next kernel version.

There's a corner case in 32 bit x86 kdump at the moment. When the box
panics via nmi, we call bust_spinlocks(1) to disable sensitivity to the
console_sem (allowing us to print to the console in all cases), but we don't
call crash_kexec, until after we call bust_spinlocks(0), which re-enables
console_sem sensitivity.
The result is that, if we get an nmi while the console_sem is held and
kdump is configured, and we try to print something to the console during
kdump shutdown (which we often do) we deadlock the box. The fix is to
simply do what 64 bit die_nmi does which is to not call bust_spinlocks(0)
until after we call crash_kexec.
Patch below tested successfully by me.

Running machine checks with interrupt on is a extremly bad idea. The machine
check handler only runs when the system is broken and needs to finish
as quickly as possible.
