Subject: [PATCH 0/2] sparc32: srmmu: improve type safety of __nocache_fix()
Date: Sun, 24 May 2020 16:21:49 +0000	[thread overview]
Message-ID: <20200524162151.3493-1-rppt@kernel.org> (raw)

From: Mike Rapoport <rppt@linux.ibm.com>

Hi,

As discussed at [1] the __nocache_fix() macro in sparc's SRMMU can be made
type safe and so the compiler will yell anout misuse of pXd pointers for
which the __nocache_fix() is primarily used.

The first patch is an fix of such misuse that I've discovered after adding
type cast to __nocache_fix(), but to avoid breaking bisection I've made it
the first commit.

Sincerely yours,
Mike.
