[PATCH v4 2/4] kvm/ppc/mpic: drop unused IRQ_testbit

From: Arseny Solokha
Date: Sat Mar 21 2015 - 02:57:17 EST

Drop unused static procedure which doesn't have callers within its
translation unit. It had been already removed independently in QEMU[1]
from the OpenPIC implementation borrowed by the kernel.

[1] https://lists.gnu.org/archive/html/qemu-devel/2014-06/msg01812.html

v4: Fixed the comment regarding the origination of OpenPIC codebase
and CC'ed KVM mailing lists, as suggested by Alexander Graf.

v3: In patch 4/4, do not remove fsl_mpic_primary_get_version() from
arch/powerpc/sysdev/mpic.c because the patch by Jia Hongtao
("powerpc/85xx: workaround for chips with MSI hardware errata") makes
use of it.

v2: Added a brief explanation to each patch description of why removed
functions are unused, as suggested by Michael Ellerman.
