On some smp sysfs store attributes get_online_cpus() may block on
cpu_hotplug.lock, but we hold already smp_cpu_state_mutex. Since the
locking order on cpu hotplug via arch_update_cpu_topology is inverse
this might lead to deadlocks.
So make sure locking order is always the same.

Because ext4_check_descriptors is called at mount time you can't use ext4_error
as it calls ext4_commit_sb, which since the sb isn't all the way initialized
causes bad things to happen (ie a panic). This patch changes the ext4_error's
to printk's to keep this problem from happening. Thanks much,

The recently announced "Linux POSIX file system test suite"
caught a truncate issue when using extents:
mtime and ctime are not updated when truncate is successful.
This is the single issue caught with "default" ext4 (mkfs and mount
with minimal options).
The testsuite does not report failure with -o noextents.
With the following patch, all tests of the testsuite pass.

Legacy HP ia64 platforms currently cannot provide
/proc/cpuinfo/physical_id due to legacy SAL/PAL implementations.
However, that physical topology information can be obtained
via ACPI.
Provide an interface that gives ACPI one last chance to provide
physical_id for these legacy platforms. This logic only comes
into play iff:
- ACPI actually provides slot information for the CPU
- we lack a valid socket_id
Otherwise, we don't do anything.
Since x86 uses the ACPI processor driver as well, we provide a nop
stub function for arch_fix_phys_package_id() in asm-x86/topology.h
