[PATCH 0/7] Fix issues and factorize arm/arm64 capacity information code

[Juri Lelli]

Hi,

arm and arm64 topology.c share a lot of code related to parsing of capacity
information. This set of patches proposes a solution (based on Will's,
Catalin's and Mark's off-line suggestions) to move such common code in a single
place: drivers/base/arch_topology.c (by creating such file and conditionally
compiling it for arm and arm64 only).

First 5 patches are actually fixes for the current code.

Patch 6 is the actual refactoring.

Last patch removes one of the extern symbols by changing a bit the now common
code. We still remain with some other externs, which are not nice. Moving them
in some header file solves the issue, should I just create a new include/
linux/arch_topology.h file and move them there?

The set is based on top of linux/master (4.10-rc4 fb1d8e0e2c50) and it is also
available from:

 git://linux-arm.org/linux-jl.git upstream/default_caps_factorize

Best,

- Juri
