mce->socketid and cpu_data(mce->cpu).phys_proc_id are the same,
compare with mce_setup (in mce.c):
m->cpu = m->extcpu = smp_processor_id();
...
m->socketid = cpu_data(m->extcpu).phys_proc_id;
This makes it easier for example for XEN patches to hook into
the MCE subsystem.

Now that we are doing the locking correctly, we need to grab the
i_completed_io_lock() twice per end_io. We can clean this up by
removing the structure from the i_complted_io_list, and use this as
the locking mechanism to prevent ext4_flush_completed_IO() racing
against ext4_end_io_work(), instead of clearing the
EXT4_IO_END_UNWRITTEN in io->flag.
In addition, if the ext4_convert_unwritten_extents() returns an error,
we no longer keep the end_io structure on the linked list. This
doesn't help, because it tends to lock up the file system and wedges
the system. That's one way to call attention to the problem, but it
doesn't help the overall robustness of the system.

Commit "ARM: gic: add irq_domain support" (b49b6ff) breaks SPARSE_IRQ
on platforms with GIC. When SPARSE_IRQ is enabled, all NR_IRQS or
mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused
irq_alloc_descs to allocate irq_descs after the pre-allocated space.
Make irq_alloc_descs search for an exact irq range and assume it has
been pre-allocated on failure. For DT probing dynamic allocation is used.
DT enabled platforms should set their nr_irqs to NR_IRQ_LEGACY and have all
irq_chips allocate their irq_descs with irq_alloc_descs if SPARSE_IRQ is
enabled.
gic_init irq_start param is changed to be signed with negative meaning do
dynamic Linux irq assigment.

Convert the gic interrupt controller to use irq domains in preparation
for device-tree binding and MULTI_IRQ. This allows for translation between
GIC interrupt IDs and Linux irq numbers.
The meaning of irq_offset has changed. It now is just the number of skipped
GIC interrupt IDs for the controller. It will be 16 for primary GIC and 32
for secondary GICs.

Interrupt controllers can have non-zero starting value for h/w irq numbers.
Adding support in irq_domain allows the domain hwirq numbering to match
the interrupt controllers' numbering.
As this makes looping over irqs for a domain more complicated, add loop
iterators to iterate over all hwirqs and irqs for a domain.

v3: detection code is x86 and KVM specific, hide it under ifdef
v2: add detection for virtual environments (KVM and Parallels)
This patch is intended to improve performance in virtualized environments
like Parallels Desktop or KVM/VirtualBox/QEMU (virtual ICH/AC97 audio).
I/O access is very time-expensive operation in virtual world: VCPU
can be rescheduled and in the worst case we get more than 10ms delay on
each I/O access.
In the virtual environment loop exit rule
(old_civ == current_civ && old_picb == current_picb) is never satisfied,
because old_picb is never the same as current_picb due to delay inspired
by reading current_civ. As a result loop ended by timeout and we get 10x
more I/O operations.
Experimental data from Prallels Desktop 7, RHEL6 guest (I/O ops per
second):
Original code:

cards. For PCIe, a single revision ID per device (RayDAT, MADI, AIO,

one revision ID per firmware version.
Instead of listing all possible revisions individually, match the range.

This is a fairly serious bug in RAID10.
When a RAID10 array is degraded and a hot-spare is activated, the
spare does not take up the empty slot, but rather replaces the first
working device.
This is likely to make the array non-functional. It would normally
be possible to recover the data, but that would need care and is not
guaranteed.
This bug was introduced in commit
2bb77736ae
