Hello,

Upon ack, please pull from the following git tree.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git tj-percpu-convert-most-archs

As per David Miller's request, I trimmed most arch maintainers from cc
list and just added the arch mailing list.

This is the third take of percpu-convert-most-archs-to-dynamic-percpu
patchset. Changes from the last take[L] are

* Rebased on the current linus#master (more updates in
enforce-global-definitions patch). The remap patchset is pushed
after this one.

* Rebased on top of tj-percpu-fix-remap.

* CRIS drop-volatile patch added.

* fix-too-lazy-vunmap-cache-flushing patch added.

This patchset contains the following nine patches.

0001-percpu-fix-too-lazy-vunmap-cache-flushing.patch
0002-percpu-use-dynamic-percpu-allocator-as-the-default.patch
0003-CRIS-Change-DEFINE_PER_CPU-of-current_pgd-to-be-non.patch
0004-percpu-cleanup-percpu-array-definitions.patch
0005-percpu-clean-up-percpu-variable-definitions.patch
0006-percpu-enforce-global-definition.patch
0007-alpha-kill-unnecessary-__used-attribute-in-PER_CPU_.patch
0008-alpha-switch-to-dynamic-percpu-allocator.patch
0009-s390-switch-to-dynamic-percpu-allocator.patch

0001 and 0003 are the new ones. Other remain mostly the same other
than added updates in 0005 and 0006 for newly introduced percpu
variables.

Kyle McMartin reported that default allocator change breaks parisc.
The problem is still under investigation and he is okay with pushing
this patchset forward and fixing parisc later.

This patchset is on top of the current
linus#master(300df7dc89cc276377fc020704e34875d5c473b6).

and contains the following changes.
