Hello,

Upon ack, please pull from the following git tree.

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

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

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

* As suggested by Rusty Russell, complex percpu definition macros
which used dummy variables to guarantee scope and uniqueness have
been dropped. Instead, now all percpu variables are required to be
global. No statics allowed. All in-kernel users are converted by
this patchset.

* Linker script .discard section handling patch no longer necessary
and dropped.

This patchset contains the following seven patches.

0001-percpu-use-dynamic-percpu-allocator-as-the-default.patch
0002-percpu-cleanup-percpu-array-definitions.patch
0003-percpu-clean-up-percpu-variable-definitions.patch
0004-percpu-enforce-global-definition.patch
0005-alpha-kill-unnecessary-__used-attribute-in-PER_CPU_.patch
0006-alpha-switch-to-dynamic-percpu-allocator.patch
0007-s390-switch-to-dynamic-percpu-allocator.patch

0001 converts archs which are easy to convert and make dynamic percpu
allocator the default. 0002-0003 prepares for percpu variable
definition change. 0004 enforces global definitions. 0005-0007
convert alpha and s390 to dynamic percpu variable using the weak
attribute.

This patchset is on top of

core/percpu (e1b9aa3f47242e757c776a3771bb6613e675bf9c)
+ linus-2.6#master (3218911f839b6c85acbf872ad264ea69aa4d89ad)
+ x86-percpu-fix-pageattr patchset, take#3 [1]

and contains the following changes.
