cmci_discover() works out which machine check banks support CMCI, and
which of those are shared by multiple logical processors. It uses this
information to ensure that exactly one cpu is designated the owner of
each bank so that when interrupts are broadcast to multiple cpus, only one
of them will look in a shared bank to log the error and clear the bank.

At boot time cmci_discover() performs this task silently. But during
certain cpu hotplug operations it prints out a set of summary lines
like this:

CPU 35 MCA banks CMCI:0 CMCI:1 CMCI:3 CMCI:5 CMCI:6 CMCI:7 CMCI:8 CMCI:9 CMCI:10 CMCI:11
CPU 1 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 39 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 38 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 32 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 37 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 36 MCA banks CMCI:0 CMCI:1 CMCI:3
CPU 34 MCA banks CMCI:0 CMCI:1 CMCI:3

The value of these messages seems very low. A user might painstakingly
cross-check against the data sheet for a processor to ensure that all
CMCI supported banks are correctly reported, but this seems improbable.
If users really wanted to do this, we should print the information at
boot time too.

Remove the messages.

There are two ways to create /sys/firmware/memmap/X sysfs:

  - firmware_map_add_early
    When the system starts, it is calledd from e820_reserve_resources()
  - firmware_map_add_hotplug
    When the memory is hot plugged, it is called from add_memory()

But these functions are called without unifying value of end argument as
below:

  - end argument of firmware_map_add_early()   : start + size - 1
  - end argument of firmware_map_add_hogplug() : start + size

The patch unifies them to "start + size".  Even if applying the patch,
/sys/firmware/memmap/X/end file content does not change.

there are 3 funcs which need to be _initcalled in a logic sequence:

xen_late_init_mcelog must register xen_mce_chrdev_device before
native mce_chrdev_device registration if running under xen platform;

mcheck_init_device should be inited before threshold_init_device to
initialize mce_device, otherwise a a NULL ptr dereference will cause panic.

so we use following _initcalls
1. device_initcall(xen_late_init_mcelog);
2. device_initcall_sync(mcheck_init_device);

x86/apic/x2apic: Use multiple cluster members for the irq destination only with the explicit affinity

During boot or driver load etc, interrupt destination is setup
using default target cpu's. Later the user (irqbalance etc) or
the driver (irq_set_affinity/ irq_set_affinity_hint) can request
the interrupt to be migrated to some specific set of cpu's.

In the x2apic cluster routing, for the default scenario use
single cpu as the interrupt destination and when there is an
explicit interrupt affinity request, route the interrupt to
multiple members of a x2apic cluster specified in the cpumask of
the migration request.

This will minmize the vector pressure when there are lot of
interrupt sources and relatively few x2apic clusters (for
example a single socket server). This will allow the performance
critical interrupts to be routed to multiple cpu's in the x2apic
cluster (irqbalance for example uses the cache siblings etc
while specifying the interrupt destination) and allow
non-critical interrupts to be serviced by a single logical cpu.

For the x2apic cluster mode, vector for an interrupt is
currently reserved on all the cpu's that are part of the x2apic
cluster. But the interrupts will be routed only to the cluster
(derived from the first cpu in the mask) members specified in
the mask. So there is no need to reserve the vector in the
unused cluster members.

Modify __assign_irq_vector() to reserve the vectors based on the
user specified irq destination mask. If the new mask is a proper
subset of the currently used mask, cleanup the vector allocation
on the unused cpu members.

Also, allow the apic driver to tune the vector domain based on
the affinity mask (which in most cases is the user-specified
mask).

Currently __assign_irq_vector() goes through each cpu in the
specified mask until it finds a free vector in all the cpu's
that are part of the same interrupt domain. We visit all the
interrupt domain sibling cpus to reserve the free vector. So,
when we fail to find a free vector in an interrupt domain, it is
safe to continue our search with a cpu belonging to a new
interrupt domain. No need to go through each cpu, if the domain
containing that cpu is already visited.

Use the irq_cfg's old_domain to track the visited domains and
optimize the cpu traversal while finding a free vector in the
given cpumask.

NOTE: We can also optimize the search by using for_each_cpu() and
skip the current cpu, if it is not the first cpu in the mask
returned by the vector_allocation_domain(). But re-using the
cfg->old_domain to track the visited domains will be slightly
faster.
