[PATCH v2 0/2] netfilter: nf_tables: Fix percpu address space issues in nf_tables_api.c

[Uros Bizjak <ubizjak@gmail.com>]

Use {ERR_PTR,IS_ERR,PTR_ERR}_PCPU() macros when crossing between generic
and percpu address spaces and add __percpu annotation to *stats pointer
to fix percpu address space issues.

NOTE: The patch depends on a patch that introduces *_PCPU() macros [1]
that is on the way to mainline through the mm tree. For convience, the
patch is included in this patch series, so CI tester is able to test
the second patch without compile failures.

The netfilter patch obsoletes patch [2].
